+ The xdg_wm_base interface is exposed as a global object enabling clients
+ to turn their wl_surfaces into windows in a desktop environment. It
+ defines the basic functionality needed for clients and the compositor to
+ create windows that can be dragged, resized, maximized, etc, as well as
+ creating transient windows such as popup menus.
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+ Destroy this xdg_wm_base object.
+
+ Destroying a bound xdg_wm_base object while there are surfaces
+ still alive created by this xdg_wm_base object instance is illegal
+ and will result in a defunct_surfaces error.
+
+
+
+
+
+ Create a positioner object. A positioner object is used to position
+ surfaces relative to some parent surface. See the interface description
+ and xdg_surface.get_popup for details.
+
+
+
+
+
+
+ This creates an xdg_surface for the given surface. While xdg_surface
+ itself is not a role, the corresponding surface may only be assigned
+ a role extending xdg_surface, such as xdg_toplevel or xdg_popup. It is
+ illegal to create an xdg_surface for a wl_surface which already has an
+ assigned role and this will result in a role error.
+
+ This creates an xdg_surface for the given surface. An xdg_surface is
+ used as basis to define a role to a given surface, such as xdg_toplevel
+ or xdg_popup. It also manages functionality shared between xdg_surface
+ based surface roles.
+
+ See the documentation of xdg_surface for more details about what an
+ xdg_surface is and how it is used.
+
+
+
+
+
+
+
+ A client must respond to a ping event with a pong request or
+ the client may be deemed unresponsive. See xdg_wm_base.ping
+ and xdg_wm_base.error.unresponsive.
+
+
+
+
+
+
+ The ping event asks the client if it's still alive. Pass the
+ serial specified in the event back to the compositor by sending
+ a "pong" request back with the specified serial. See xdg_wm_base.pong.
+
+ Compositors can use this to determine if the client is still
+ alive. It's unspecified what will happen if the client doesn't
+ respond to the ping request, or in what timeframe. Clients should
+ try to respond in a reasonable amount of time. The “unresponsive”
+ error is provided for compositors that wish to disconnect unresponsive
+ clients.
+
+ A compositor is free to ping in any way it wants, but a client must
+ always respond to any xdg_wm_base object it created.
+
+
+
+
+
+
+
+ The xdg_positioner provides a collection of rules for the placement of a
+ child surface relative to a parent surface. Rules can be defined to ensure
+ the child surface remains within the visible area's borders, and to
+ specify how the child surface changes its position, such as sliding along
+ an axis, or flipping around a rectangle. These positioner-created rules are
+ constrained by the requirement that a child surface must intersect with or
+ be at least partially adjacent to its parent surface.
+
+ See the various requests for details about possible rules.
+
+ At the time of the request, the compositor makes a copy of the rules
+ specified by the xdg_positioner. Thus, after the request is complete the
+ xdg_positioner object can be destroyed or reused; further changes to the
+ object will have no effect on previous usages.
+
+ For an xdg_positioner object to be considered complete, it must have a
+ non-zero size set by set_size, and a non-zero anchor rectangle set by
+ set_anchor_rect. Passing an incomplete xdg_positioner object when
+ positioning a surface raises an invalid_positioner error.
+
+
+
+
+
+
+
+
+ Notify the compositor that the xdg_positioner will no longer be used.
+
+
+
+
+
+ Set the size of the surface that is to be positioned with the positioner
+ object. The size is in surface-local coordinates and corresponds to the
+ window geometry. See xdg_surface.set_window_geometry.
+
+ If a zero or negative size is set the invalid_input error is raised.
+
+
+
+
+
+
+
+ Specify the anchor rectangle within the parent surface that the child
+ surface will be placed relative to. The rectangle is relative to the
+ window geometry as defined by xdg_surface.set_window_geometry of the
+ parent surface.
+
+ When the xdg_positioner object is used to position a child surface, the
+ anchor rectangle may not extend outside the window geometry of the
+ positioned child's parent surface.
+
+ If a negative size is set the invalid_input error is raised.
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+ Defines the anchor point for the anchor rectangle. The specified anchor
+ is used derive an anchor point that the child surface will be
+ positioned relative to. If a corner anchor is set (e.g. 'top_left' or
+ 'bottom_right'), the anchor point will be at the specified corner;
+ otherwise, the derived anchor point will be centered on the specified
+ edge, or in the center of the anchor rectangle if no edge is specified.
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+ Defines in what direction a surface should be positioned, relative to
+ the anchor point of the parent surface. If a corner gravity is
+ specified (e.g. 'bottom_right' or 'top_left'), then the child surface
+ will be placed towards the specified gravity; otherwise, the child
+ surface will be centered over the anchor point on any axis that had no
+ gravity specified. If the gravity is not in the ‘gravity’ enum, an
+ invalid_input error is raised.
+
+
+
+
+
+
+ The constraint adjustment value define ways the compositor will adjust
+ the position of the surface, if the unadjusted position would result
+ in the surface being partly constrained.
+
+ Whether a surface is considered 'constrained' is left to the compositor
+ to determine. For example, the surface may be partly outside the
+ compositor's defined 'work area', thus necessitating the child surface's
+ position be adjusted until it is entirely inside the work area.
+
+ The adjustments can be combined, according to a defined precedence: 1)
+ Flip, 2) Slide, 3) Resize.
+
+
+
+ Don't alter the surface position even if it is constrained on some
+ axis, for example partially outside the edge of an output.
+
+
+
+
+ Slide the surface along the x axis until it is no longer constrained.
+
+ First try to slide towards the direction of the gravity on the x axis
+ until either the edge in the opposite direction of the gravity is
+ unconstrained or the edge in the direction of the gravity is
+ constrained.
+
+ Then try to slide towards the opposite direction of the gravity on the
+ x axis until either the edge in the direction of the gravity is
+ unconstrained or the edge in the opposite direction of the gravity is
+ constrained.
+
+
+
+
+ Slide the surface along the y axis until it is no longer constrained.
+
+ First try to slide towards the direction of the gravity on the y axis
+ until either the edge in the opposite direction of the gravity is
+ unconstrained or the edge in the direction of the gravity is
+ constrained.
+
+ Then try to slide towards the opposite direction of the gravity on the
+ y axis until either the edge in the direction of the gravity is
+ unconstrained or the edge in the opposite direction of the gravity is
+ constrained.
+
+
+
+
+ Invert the anchor and gravity on the x axis if the surface is
+ constrained on the x axis. For example, if the left edge of the
+ surface is constrained, the gravity is 'left' and the anchor is
+ 'left', change the gravity to 'right' and the anchor to 'right'.
+
+ If the adjusted position also ends up being constrained, the resulting
+ position of the flip_x adjustment will be the one before the
+ adjustment.
+
+
+
+
+ Invert the anchor and gravity on the y axis if the surface is
+ constrained on the y axis. For example, if the bottom edge of the
+ surface is constrained, the gravity is 'bottom' and the anchor is
+ 'bottom', change the gravity to 'top' and the anchor to 'top'.
+
+ The adjusted position is calculated given the original anchor
+ rectangle and offset, but with the new flipped anchor and gravity
+ values.
+
+ If the adjusted position also ends up being constrained, the resulting
+ position of the flip_y adjustment will be the one before the
+ adjustment.
+
+
+
+
+ Resize the surface horizontally so that it is completely
+ unconstrained.
+
+
+
+
+ Resize the surface vertically so that it is completely unconstrained.
+
+
+
+
+
+
+ Specify how the window should be positioned if the originally intended
+ position caused the surface to be constrained, meaning at least
+ partially outside positioning boundaries set by the compositor. The
+ adjustment is set by constructing a bitmask describing the adjustment to
+ be made when the surface is constrained on that axis.
+
+ If no bit for one axis is set, the compositor will assume that the child
+ surface should not change its position on that axis when constrained.
+
+ If more than one bit for one axis is set, the order of how adjustments
+ are applied is specified in the corresponding adjustment descriptions.
+
+ The default adjustment is none.
+
+
+
+
+
+
+ Specify the surface position offset relative to the position of the
+ anchor on the anchor rectangle and the anchor on the surface. For
+ example if the anchor of the anchor rectangle is at (x, y), the surface
+ has the gravity bottom|right, and the offset is (ox, oy), the calculated
+ surface position will be (x + ox, y + oy). The offset position of the
+ surface is the one used for constraint testing. See
+ set_constraint_adjustment.
+
+ An example use case is placing a popup menu on top of a user interface
+ element, while aligning the user interface element of the parent surface
+ with some user interface element placed somewhere in the popup surface.
+
+
+
+
+
+
+
+
+
+ When set reactive, the surface is reconstrained if the conditions used
+ for constraining changed, e.g. the parent window moved.
+
+ If the conditions changed and the popup was reconstrained, an
+ xdg_popup.configure event is sent with updated geometry, followed by an
+ xdg_surface.configure event.
+
+
+
+
+
+ Set the parent window geometry the compositor should use when
+ positioning the popup. The compositor may use this information to
+ determine the future state the popup should be constrained using. If
+ this doesn't match the dimension of the parent the popup is eventually
+ positioned against, the behavior is undefined.
+
+ The arguments are given in the surface-local coordinate space.
+
+
+
+
+
+
+
+ Set the serial of an xdg_surface.configure event this positioner will be
+ used in response to. The compositor may use this information together
+ with set_parent_size to determine what future state the popup should be
+ constrained using.
+
+
+
+
+
+
+
+ An interface that may be implemented by a wl_surface, for
+ implementations that provide a desktop-style user interface.
+
+ It provides a base set of functionality required to construct user
+ interface elements requiring management by the compositor, such as
+ toplevel windows, menus, etc. The types of functionality are split into
+ xdg_surface roles.
+
+ Creating an xdg_surface does not set the role for a wl_surface. In order
+ to map an xdg_surface, the client must create a role-specific object
+ using, e.g., get_toplevel, get_popup. The wl_surface for any given
+ xdg_surface can have at most one role, and may not be assigned any role
+ not based on xdg_surface.
+
+ A role must be assigned before any other requests are made to the
+ xdg_surface object.
+
+ The client must call wl_surface.commit on the corresponding wl_surface
+ for the xdg_surface state to take effect.
+
+ Creating an xdg_surface from a wl_surface which has a buffer attached or
+ committed is a client error, and any attempts by a client to attach or
+ manipulate a buffer prior to the first xdg_surface.configure call must
+ also be treated as errors.
+
+ After creating a role-specific object and setting it up (e.g. by sending
+ the title, app ID, size constraints, parent, etc), the client must
+ perform an initial commit without any buffer attached. The compositor
+ will reply with initial wl_surface state such as
+ wl_surface.preferred_buffer_scale followed by an xdg_surface.configure
+ event. The client must acknowledge it and is then allowed to attach a
+ buffer to map the surface.
+
+ Mapping an xdg_surface-based role surface is defined as making it
+ possible for the surface to be shown by the compositor. Note that
+ a mapped surface is not guaranteed to be visible once it is mapped.
+
+ For an xdg_surface to be mapped by the compositor, the following
+ conditions must be met:
+ (1) the client has assigned an xdg_surface-based role to the surface
+ (2) the client has set and committed the xdg_surface state and the
+ role-dependent state to the surface
+ (3) the client has committed a buffer to the surface
+
+ A newly-unmapped surface is considered to have met condition (1) out
+ of the 3 required conditions for mapping a surface if its role surface
+ has not been destroyed, i.e. the client must perform the initial commit
+ again before attaching a buffer.
+
+
+
+
+
+
+
+
+
+
+
+
+
+ Destroy the xdg_surface object. An xdg_surface must only be destroyed
+ after its role object has been destroyed, otherwise
+ a defunct_role_object error is raised.
+
+
+
+
+
+ This creates an xdg_toplevel object for the given xdg_surface and gives
+ the associated wl_surface the xdg_toplevel role.
+
+ See the documentation of xdg_toplevel for more details about what an
+ xdg_toplevel is and how it is used.
+
+
+
+
+
+
+ This creates an xdg_popup object for the given xdg_surface and gives
+ the associated wl_surface the xdg_popup role.
+
+ If null is passed as a parent, a parent surface must be specified using
+ some other protocol, before committing the initial state.
+
+ See the documentation of xdg_popup for more details about what an
+ xdg_popup is and how it is used.
+
+
+
+
+
+
+
+
+ The window geometry of a surface is its "visible bounds" from the
+ user's perspective. Client-side decorations often have invisible
+ portions like drop-shadows which should be ignored for the
+ purposes of aligning, placing and constraining windows.
+
+ The window geometry is double-buffered state, see wl_surface.commit.
+
+ When maintaining a position, the compositor should treat the (x, y)
+ coordinate of the window geometry as the top left corner of the window.
+ A client changing the (x, y) window geometry coordinate should in
+ general not alter the position of the window.
+
+ Once the window geometry of the surface is set, it is not possible to
+ unset it, and it will remain the same until set_window_geometry is
+ called again, even if a new subsurface or buffer is attached.
+
+ If never set, the value is the full bounds of the surface,
+ including any subsurfaces. This updates dynamically on every
+ commit. This unset is meant for extremely simple clients.
+
+ The arguments are given in the surface-local coordinate space of
+ the wl_surface associated with this xdg_surface, and may extend outside
+ of the wl_surface itself to mark parts of the subsurface tree as part of
+ the window geometry.
+
+ When applied, the effective window geometry will be the set window
+ geometry clamped to the bounding rectangle of the combined
+ geometry of the surface of the xdg_surface and the associated
+ subsurfaces.
+
+ The effective geometry will not be recalculated unless a new call to
+ set_window_geometry is done and the new pending surface state is
+ subsequently applied.
+
+ The width and height of the effective window geometry must be
+ greater than zero. Setting an invalid size will raise an
+ invalid_size error.
+
+
+
+
+
+
+
+
+
+ When a configure event is received, if a client commits the
+ surface in response to the configure event, then the client
+ must make an ack_configure request sometime before the commit
+ request, passing along the serial of the configure event.
+
+ For instance, for toplevel surfaces the compositor might use this
+ information to move a surface to the top left only when the client has
+ drawn itself for the maximized or fullscreen state.
+
+ If the client receives multiple configure events before it
+ can respond to one, it only has to ack the last configure event.
+ Acking a configure event that was never sent raises an invalid_serial
+ error.
+
+ A client is not required to commit immediately after sending
+ an ack_configure request - it may even ack_configure several times
+ before its next surface commit.
+
+ A client may send multiple ack_configure requests before committing, but
+ only the last request sent before a commit indicates which configure
+ event the client really is responding to.
+
+ Sending an ack_configure request consumes the serial number sent with
+ the request, as well as serial numbers sent by all configure events
+ sent on this xdg_surface prior to the configure event referenced by
+ the committed serial.
+
+ It is an error to issue multiple ack_configure requests referencing a
+ serial from the same configure event, or to issue an ack_configure
+ request referencing a serial from a configure event issued before the
+ event identified by the last ack_configure request for the same
+ xdg_surface. Doing so will raise an invalid_serial error.
+
+
+
+
+
+
+ The configure event marks the end of a configure sequence. A configure
+ sequence is a set of one or more events configuring the state of the
+ xdg_surface, including the final xdg_surface.configure event.
+
+ Where applicable, xdg_surface surface roles will during a configure
+ sequence extend this event as a latched state sent as events before the
+ xdg_surface.configure event. Such events should be considered to make up
+ a set of atomically applied configuration states, where the
+ xdg_surface.configure commits the accumulated state.
+
+ Clients should arrange their surface for the new states, and then send
+ an ack_configure request with the serial sent in this configure event at
+ some point before committing the new surface.
+
+ If the client receives multiple configure events before it can respond
+ to one, it is free to discard all but the last event it received.
+
+
+
+
+
+
+
+
+ This interface defines an xdg_surface role which allows a surface to,
+ among other things, set window-like properties such as maximize,
+ fullscreen, and minimize, set application-specific metadata like title and
+ id, and well as trigger user interactive operations such as interactive
+ resize and move.
+
+ A xdg_toplevel by default is responsible for providing the full intended
+ visual representation of the toplevel, which depending on the window
+ state, may mean things like a title bar, window controls and drop shadow.
+
+ Unmapping an xdg_toplevel means that the surface cannot be shown
+ by the compositor until it is explicitly mapped again.
+ All active operations (e.g., move, resize) are canceled and all
+ attributes (e.g. title, state, stacking, ...) are discarded for
+ an xdg_toplevel surface when it is unmapped. The xdg_toplevel returns to
+ the state it had right after xdg_surface.get_toplevel. The client
+ can re-map the toplevel by performing a commit without any buffer
+ attached, waiting for a configure event and handling it as usual (see
+ xdg_surface description).
+
+ Attaching a null buffer to a toplevel unmaps the surface.
+
+
+
+
+ This request destroys the role surface and unmaps the surface;
+ see "Unmapping" behavior in interface section for details.
+
+
+
+
+
+
+
+
+
+
+
+ Set the "parent" of this surface. This surface should be stacked
+ above the parent surface and all other ancestor surfaces.
+
+ Parent surfaces should be set on dialogs, toolboxes, or other
+ "auxiliary" surfaces, so that the parent is raised when the dialog
+ is raised.
+
+ Setting a null parent for a child surface unsets its parent. Setting
+ a null parent for a surface which currently has no parent is a no-op.
+
+ Only mapped surfaces can have child surfaces. Setting a parent which
+ is not mapped is equivalent to setting a null parent. If a surface
+ becomes unmapped, its children's parent is set to the parent of
+ the now-unmapped surface. If the now-unmapped surface has no parent,
+ its children's parent is unset. If the now-unmapped surface becomes
+ mapped again, its parent-child relationship is not restored.
+
+ The parent toplevel must not be one of the child toplevel's
+ descendants, and the parent must be different from the child toplevel,
+ otherwise the invalid_parent protocol error is raised.
+
+
+
+
+
+
+ Set a short title for the surface.
+
+ This string may be used to identify the surface in a task bar,
+ window list, or other user interface elements provided by the
+ compositor.
+
+ The string must be encoded in UTF-8.
+
+
+
+
+
+
+ Set an application identifier for the surface.
+
+ The app ID identifies the general class of applications to which
+ the surface belongs. The compositor can use this to group multiple
+ surfaces together, or to determine how to launch a new application.
+
+ For D-Bus activatable applications, the app ID is used as the D-Bus
+ service name.
+
+ The compositor shell will try to group application surfaces together
+ by their app ID. As a best practice, it is suggested to select app
+ ID's that match the basename of the application's .desktop file.
+ For example, "org.freedesktop.FooViewer" where the .desktop file is
+ "org.freedesktop.FooViewer.desktop".
+
+ Like other properties, a set_app_id request can be sent after the
+ xdg_toplevel has been mapped to update the property.
+
+ See the desktop-entry specification [0] for more details on
+ application identifiers and how they relate to well-known D-Bus
+ names and .desktop files.
+
+ [0] https://standards.freedesktop.org/desktop-entry-spec/
+
+
+
+
+
+
+ Clients implementing client-side decorations might want to show
+ a context menu when right-clicking on the decorations, giving the
+ user a menu that they can use to maximize or minimize the window.
+
+ This request asks the compositor to pop up such a window menu at
+ the given position, relative to the local surface coordinates of
+ the parent surface. There are no guarantees as to what menu items
+ the window menu contains, or even if a window menu will be drawn
+ at all.
+
+ This request must be used in response to some sort of user action
+ like a button press, key press, or touch down event.
+
+
+
+
+
+
+
+
+
+ Start an interactive, user-driven move of the surface.
+
+ This request must be used in response to some sort of user action
+ like a button press, key press, or touch down event. The passed
+ serial is used to determine the type of interactive move (touch,
+ pointer, etc).
+
+ The server may ignore move requests depending on the state of
+ the surface (e.g. fullscreen or maximized), or if the passed serial
+ is no longer valid.
+
+ If triggered, the surface will lose the focus of the device
+ (wl_pointer, wl_touch, etc) used for the move. It is up to the
+ compositor to visually indicate that the move is taking place, such as
+ updating a pointer cursor, during the move. There is no guarantee
+ that the device focus will return when the move is completed.
+
+
+
+

+ is being dragged in a resize operation.

+
+ Start a user-driven, interactive resize of the surface.
+
+ This request must be used in response to some sort of user action
+ like a button press, key press, or touch down event. The passed
+ serial is used to determine the type of interactive resize (touch,
+ pointer, etc).
+
+ The server may ignore resize requests depending on the state of
+ the surface (e.g. fullscreen or maximized).
+
+ If triggered, the client will receive configure events with the
+ "resize" state enum value and the expected sizes. See the "resize"
+ enum value for more details about what is required. The client
+ must also acknowledge configure events using "ack_configure". After
+ the resize is completed, the client will receive another "configure"
+ event without the resize state.
+
+ If triggered, the surface also will lose the focus of the device
+ (wl_pointer, wl_touch, etc) used for the resize. It is up to the
+ compositor to visually indicate that the resize is taking place,
+ such as updating a pointer cursor, during the resize. There is no
+ guarantee that the device focus will return when the resize is
+ completed.
+
+ The edges parameter specifies how the surface should be resized, and
+ is one of the values of the resize_edge enum. Values not matching
+ a variant of the enum will cause the invalid_resize_edge protocol error.
+ The compositor may use this information to update the surface position
+ for example when dragging the top left corner. The compositor may also
+ use this information to adapt its behavior, e.g. choose an appropriate

+ The different state values used on the surface. This is designed for
+ state values like maximized, fullscreen. It is paired with the
+ configure event to ensure that both the client and the compositor
+ setting the state can be synchronized.
+
+ States set in this way are double-buffered, see wl_surface.commit.
+
+
+
+ The surface is maximized. The window geometry specified in the configure
+ event must be obeyed by the client, or the xdg_wm_base.invalid_surface_state
+ error is raised.
+
+ The client should draw without shadow or other
+ decoration outside of the window geometry.
+
+
+
+
+ The surface is fullscreen. The window geometry specified in the
+ configure event is a maximum; the client cannot resize beyond it. For
+ a surface to cover the whole fullscreened area, the geometry
+ dimensions must be obeyed by the client. For more details, see
+ xdg_toplevel.set_fullscreen.

+
+ The surface is being resized. The window geometry specified in the

+ Clients that have aspect ratio or cell sizing configuration can use
+ a smaller size, however.
+
+
+
+
+ Client window decorations should be painted as if the window is
+ active. Do not assume this means that the window actually has
+ keyboard or pointer focus.
+
+
+
+
+ The window is currently in a tiled layout and the left edge is
+ considered to be adjacent to another part of the tiling grid.
+
+ The client should draw without shadow or other decoration outside of

+
+
+
+
+ The window is currently in a tiled layout and the right edge is

+
+
+ Set a maximum size for the window.
+
+ The client can specify a maximum size so that the compositor does
+ not try to configure the window beyond this size.
+
+ The width and height arguments are in window geometry coordinates.
+ See xdg_surface.set_window_geometry.
+
+ Values set in this way are double-buffered, see wl_surface.commit.
+
+ The compositor can use this information to allow or disallow
+ different states like maximize or fullscreen and draw accurate
+ animations.
+
+ Similarly, a tiling window manager may use this information to
+ place and resize client windows in a more effective way.
+
+ The client should not rely on the compositor to obey the maximum
+ size. The compositor may decide to ignore the values set by the
+ client and request a larger size.
+
+ If never set, or a value of zero in the request, means that the
+ client has no expected maximum size in the given dimension.
+ As a result, a client wishing to reset the maximum size
+ to an unspecified state can use zero for width and height in the
+ request.
+
+ Requesting a maximum size to be smaller than the minimum size of
+ a surface is illegal and will result in an invalid_size error.
+
+ The width and height must be greater than or equal to zero. Using
+ strictly negative values for width or height will result in a
+ invalid_size error.
+
+
+
+
+
+
+
+ Set a minimum size for the window.
+
+ The client can specify a minimum size so that the compositor does
+ not try to configure the window below this size.

+
+
+
+
+
+
+
+ Maximize the surface.
+
+ After requesting that the surface should be maximized, the compositor
+ will respond by emitting a configure event. Whether this configure
+ actually sets the window maximized is subject to compositor policies.
+ The client must then update its content, drawing in the configured
+ state. The client must also acknowledge the configure when committing
+ the new content (see ack_configure).
+
+ It is up to the compositor to decide how and where to maximize the
+ surface, for example which output and what region of the screen should
+ be used.
+
+ If the surface was already maximized, the compositor will still emit
+ a configure event with the "maximized" state.
+
+ If the surface is in a fullscreen state, this request has no direct
+ effect. It may alter the state the surface is returned to when
+ unmaximized unless overridden by the compositor.
+
+
+
+
+
+ Unmaximize the surface.
+
+ After requesting that the surface should be unmaximized, the compositor
+ will respond by emitting a configure event. Whether this actually
+ un-maximizes the window is subject to compositor policies.
+ If available and applicable, the compositor will include the window
+ geometry dimensions the window had prior to being maximized in the
+ configure event. The client must then update its content, drawing it in
+ the configured state. The client must also acknowledge the configure
+ when committing the new content (see ack_configure).
+
+ It is up to the compositor to position the surface after it was
+ unmaximized; usually the position the surface had before maximizing, if
+ applicable.
+
+ If the surface was already not maximized, the compositor will still
+ emit a configure event without the "maximized" state.
+
+ If the surface is in a fullscreen state, this request has no direct
+ effect. It may alter the state the surface is returned to when
+ unmaximized unless overridden by the compositor.
+
+
+
+
+
+ Make the surface fullscreen.
+
+ After requesting that the surface should be fullscreened, the
+ compositor will respond by emitting a configure event. Whether the
+ client is actually put into a fullscreen state is subject to compositor
+ policies. The client must also acknowledge the configure when
+ committing the new content (see ack_configure).
+
+ The output passed by the request indicates the client's preference as
+ to which display it should be set fullscreen on. If this value is NULL,
+ it's up to the compositor to choose which display will be used to map
+ this surface.
+
+ If the surface doesn't cover the whole output, the compositor will
+ position the surface in the center of the output and compensate with
+ with border fill covering the rest of the output. The content of the
+ border fill is undefined, but should be assumed to be in some way that
+ attempts to blend into the surrounding area (e.g. solid black).
+
+ If the fullscreened surface is not opaque, the compositor must make
+ sure that other screen content not part of the same surface tree (made
+ up of subsurfaces, popups or similarly coupled surfaces) are not
+ visible below the fullscreened surface.
+
+
+
+
+
+
+ Make the surface no longer fullscreen.
+
+ After requesting that the surface should be unfullscreened, the
+ compositor will respond by emitting a configure event.
+ Whether this actually removes the fullscreen state of the client is
+ subject to compositor policies.
+
+ Making a surface unfullscreen sets states for the surface based on the following:
+ * the state(s) it may have had before becoming fullscreen
+ * any state(s) decided by the compositor
+ * any state(s) requested by the client while the surface was fullscreen
+
+ The compositor may include the previous window geometry dimensions in
+ the configure event, if applicable.
+
+ The client must also acknowledge the configure when committing the new
+ content (see ack_configure).
+
+
+
+
+
+ Request that the compositor minimize your surface. There is no
+ way to know if the surface is currently minimized, nor is there
+ any way to unset minimization on this surface.
+
+ If you are looking to throttle redrawing when minimized, please
+ instead use the wl_surface.frame event for this, as this will
+ also work with live previews on windows in Alt-Tab, Expose or
+ similar compositor features.
+
+
+
+
+
+ This configure event asks the client to resize its toplevel surface or
+ to change its state. The configured state should not be applied
+ immediately. See xdg_surface.configure for details.
+
+ The width and height arguments specify a hint to the window
+ about how its surface should be resized in window geometry
+ coordinates. See set_window_geometry.
+
+ If the width or height arguments are zero, it means the client
+ should decide its own window dimension. This may happen when the
+ compositor needs to configure the state of the surface but doesn't
+ have any information about any previous or expected dimension.
+
+ The states listed in the event specify how the width/height
+ arguments should be interpreted, and possibly how it should be
+ drawn.
+
+ Clients must send an ack_configure in response to this event. See
+ xdg_surface.configure and xdg_surface.ack_configure for details.
+
+
+
+
+
+
+
+
+ The close event is sent by the compositor when the user
+ wants the surface to be closed. This should be equivalent to
+ the user clicking the close button in client-side decorations,
+ if your application has any.
+
+ This is only a request that the user intends to close the
+ window. The client may choose to ignore this request, or show
+ a dialog to ask the user to save their data, etc.
+
+
+
+
+
+
+
+ The configure_bounds event may be sent prior to a xdg_toplevel.configure
+ event to communicate the bounds a window geometry size is recommended
+ to constrain to.
+
+ The passed width and height are in surface coordinate space. If width
+ and height are 0, it means bounds is unknown and equivalent to as if no
+ configure_bounds event was ever sent for this surface.
+
+ The bounds can for example correspond to the size of a monitor excluding
+ any panels or other shell components, so that a surface isn't created in
+ a way that it cannot fit.
+
+ The bounds may change at any point, and in such a case, a new
+ xdg_toplevel.configure_bounds will be sent, followed by
+ xdg_toplevel.configure and xdg_surface.configure.
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+ This event advertises the capabilities supported by the compositor. If
+ a capability isn't supported, clients should hide or disable the UI
+ elements that expose this functionality. For instance, if the
+ compositor doesn't advertise support for minimized toplevels, a button
+ triggering the set_minimized request should not be displayed.
+
+ The compositor will ignore requests it doesn't support. For instance,
+ a compositor which doesn't advertise support for minimized will ignore
+ set_minimized requests.
+
+ Compositors must send this event once before the first
+ xdg_surface.configure event. When the capabilities change, compositors
+ must send this event again and then send an xdg_surface.configure
+ event.
+
+ The configured state should not be applied immediately. See
+ xdg_surface.configure for details.
+
+ The capabilities are sent as an array of 32-bit unsigned integers in
+ native endianness.
+
+
+
+
+
+
+
+ A popup surface is a short-lived, temporary surface. It can be used to
+ implement for example menus, popovers, tooltips and other similar user
+ interface concepts.
+
+ A popup can be made to take an explicit grab. See xdg_popup.grab for
+ details.
+
+ When the popup is dismissed, a popup_done event will be sent out, and at
+ the same time the surface will be unmapped. See the xdg_popup.popup_done
+ event for details.
+
+ Explicitly destroying the xdg_popup object will also dismiss the popup and
+ unmap the surface. Clients that want to dismiss the popup when another
+ surface of their own is clicked should dismiss the popup using the destroy
+ request.
+
+ A newly created xdg_popup will be stacked on top of all previously created
+ xdg_popup surfaces associated with the same xdg_toplevel.
+
+ The parent of an xdg_popup must be mapped (see the xdg_surface
+ description) before the xdg_popup itself.
+
+ The client must call wl_surface.commit on the corresponding wl_surface
+ for the xdg_popup state to take effect.
+
+
+
+
+
+
+
+
+ This destroys the popup. Explicitly destroying the xdg_popup
+ object will also dismiss the popup, and unmap the surface.
+
+ If this xdg_popup is not the "topmost" popup, the
+ xdg_wm_base.not_the_topmost_popup protocol error will be sent.
+
+
+
+
+
+ This request makes the created popup take an explicit grab. An explicit
+ grab will be dismissed when the user dismisses the popup, or when the
+ client destroys the xdg_popup. This can be done by the user clicking
+ outside the surface, using the keyboard, or even locking the screen
+ through closing the lid or a timeout.
+
+ If the compositor denies the grab, the popup will be immediately
+ dismissed.
+
+ This request must be used in response to some sort of user action like a
+ button press, key press, or touch down event. The serial number of the
+ event should be passed as 'serial'.
+
+ The parent of a grabbing popup must either be an xdg_toplevel surface or
+ another xdg_popup with an explicit grab. If the parent is another
+ xdg_popup it means that the popups are nested, with this popup now being
+ the topmost popup.
+
+ Nested popups must be destroyed in the reverse order they were created
+ in, e.g. the only popup you are allowed to destroy at all times is the
+ topmost one.
+
+ When compositors choose to dismiss a popup, they may dismiss every
+ nested grabbing popup as well. When a compositor dismisses popups, it
+ will follow the same dismissing order as required from the client.
+
+ If the topmost grabbing popup is destroyed, the grab will be returned to
+ the parent of the popup, if that parent previously had an explicit grab.
+
+ If the parent is a grabbing popup which has already been dismissed, this
+ popup will be immediately dismissed. If the parent is a popup that did
+ not take an explicit grab, an error will be raised.
+
+ During a popup grab, the client owning the grab will receive pointer
+ and touch events for all their surfaces as normal (similar to an
+ "owner-events" grab in X11 parlance), while the top most grabbing popup
+ will always have keyboard focus.
+
+
+
+
+
+
+
+ This event asks the popup surface to configure itself given the
+ configuration. The configured state should not be applied immediately.
+ See xdg_surface.configure for details.
+
+ The x and y arguments represent the position the popup was placed at
+ given the xdg_positioner rule, relative to the upper left corner of the
+ window geometry of the parent surface.
+
+ For version 2 or older, the configure event for an xdg_popup is only
+ ever sent once for the initial configuration. Starting with version 3,
+ it may be sent again if the popup is setup with an xdg_positioner with
+ set_reactive requested, or in response to xdg_popup.reposition requests.
+
+
+
+
+
+
+
+
+
+ The popup_done event is sent out when a popup is dismissed by the
+ compositor. The client should destroy the xdg_popup object at this
+ point.
+
+
+
+
+
+
+
+ Reposition an already-mapped popup. The popup will be placed given the
+ details in the passed xdg_positioner object, and a
+ xdg_popup.repositioned followed by xdg_popup.configure and
+ xdg_surface.configure will be emitted in response. Any parameters set
+ by the previous positioner will be discarded.
+
+ The passed token will be sent in the corresponding
+ xdg_popup.repositioned event. The new popup position will not take
+ effect until the corresponding configure event is acknowledged by the
+ client. See xdg_popup.repositioned for details. The token itself is
+ opaque, and has no other special meaning.
+
+ If multiple reposition requests are sent, the compositor may skip all
+ but the last one.
+
+ If the popup is repositioned in response to a configure event for its
+ parent, the client should send an xdg_positioner.set_parent_configure
+ and possibly an xdg_positioner.set_parent_size request to allow the
+ compositor to properly constrain the popup.
+
+ If the popup is repositioned together with a parent that is being
+ resized, but not in response to a configure event, the client should
+ send an xdg_positioner.set_parent_size request.
+
+
+
+
+
+
+
+ The repositioned event is sent as part of a popup configuration
+ sequence, together with xdg_popup.configure and lastly
+ xdg_surface.configure to notify the completion of a reposition request.
+
+ The repositioned event is to notify about the completion of a
+ xdg_popup.reposition request. The token argument is the token passed
+ in the xdg_popup.reposition request.
+
+ Immediately after this event is emitted, xdg_popup.configure and
+ xdg_surface.configure will be sent with the updated size and position,
+ as well as a new configure serial.
+
+ The client should optionally update the content of the popup, but must
+ acknowledge the new popup configuration for the new position to take
+ effect. See xdg_surface.ack_configure for details.

+
+
+ This protocol enhances normal drag and drop with the ability to move a
+ window at the same time. This allows having detachable parts of a window
+ that when dragged out of it become a new window and can be dragged over
+ an existing window to be reattached.
+
+ A typical workflow would be when the user starts dragging on top of a
+ detachable part of a window, the client would create a wl_data_source and
+ a xdg_toplevel_drag_v1 object and start the drag as normal via
+ wl_data_device.start_drag. Once the client determines that the detachable
+ window contents should be detached from the originating window, it creates
+ a new xdg_toplevel with these contents and issues a
+ xdg_toplevel_drag_v1.attach request before mapping it. From now on the new
+ window is moved by the compositor during the drag as if the client called
+ xdg_toplevel.move.
+
+ Dragging an existing window is similar. The client creates a
+ xdg_toplevel_drag_v1 object and attaches the existing toplevel before
+ starting the drag.
+
+ Clients use the existing drag and drop mechanism to detect when a window
+ can be docked or undocked. If the client wants to snap a window into a
+ parent window it should delete or unmap the dragged top-level. If the
+ contents should be detached again it attaches a new toplevel as described
+ above. If a drag operation is cancelled without being dropped, clients
+ should revert to the previous state, deleting any newly created windows
+ as appropriate. When a drag operation ends as indicated by
+ wl_data_source.dnd_drop_performed the dragged toplevel window's final
+ position is determined as if a xdg_toplevel_move operation ended.
+
+ Warning! The protocol described in this file is currently in the testing
+ phase. Backward compatible changes may be added together with the
+ corresponding interface version bump. Backward incompatible changes can
+ only be done by creating a new major version of the extension.
+
+
+
+
+
+
+
+
+ Destroy this xdg_toplevel_drag_manager_v1 object. Other objects,
+ including xdg_toplevel_drag_v1 objects created by this factory, are not
+ affected by this request.
+
+
+
+
+
+ Create an xdg_toplevel_drag for a drag and drop operation that is going
+ to be started with data_source.
+
+ This request can only be made on sources used in drag-and-drop, so it
+ must be performed before wl_data_device.start_drag. Attempting to use
+ the source other than for drag-and-drop such as in
+ wl_data_device.set_selection will raise an invalid_source error.
+
+ Destroying data_source while a toplevel is attached to the
+ xdg_toplevel_drag is undefined.

+
+
+
+
+
+
+
+

+
+ Destroy this xdg_toplevel_drag_v1 object. This request must only be
+ called after the underlying wl_data_source drag has ended, as indicated
+ by the dnd_drop_performed or cancelled events. In any other case an
+ ongoing_drag error is raised.
+
+
+
+
+
+ Request that the window will be moved with the cursor during the drag
+ operation. The offset is a hint to the compositor how the toplevel
+ should be positioned relative to the cursor hotspot in surface local
+ coordinates and relative to the geometry of the toplevel being attached.
+ See xdg_surface.set_window_geometry. For example it might only
+ be used when an unmapped window is attached. The attached window
+ does not participate in the selection of the drag target.
+
+ If the toplevel is unmapped while it is attached, it is automatically
+ detached from the drag. In this case this request has to be called again
+ if the window should be attached after it is remapped.
+
+ This request can be called multiple times but issuing it while a
+ toplevel with an active role is attached raises a toplevel_attached
+ error.
