496// 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. Note that in some situations, compositors may clip rendering to the window geometry, so the client should avoid putting functional elements outside of it. 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.

504// 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 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).

884// 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.

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.
