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.

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.

The client must then update its content, drawing it in + the configured state.

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.

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.
