|
|
<description summary="short-lived, popup surfaces for menus">
|
|
A popup surface is a short-lived, temporary surface that can be
|
|
used to implement menus. It takes an explicit grab on the surface
|
|
that will be dismissed when the user dismisses the 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.
|
|
|
|
When the popup is dismissed, a popup_done event will be sent out,
|
|
and at the same time the surface will be unmapped. The xdg_popup
|
|
object is now inert and cannot be reactivated, so clients should
|
|
destroy it. Explicitly destroying the xdg_popup object will also
|
|
dismiss the popup and unmap the surface.
|
|
|
|
Clients will receive events for all their surfaces during this
|
|
grab (which is an "owner-events" grab in X11 parlance). This is
|
|
done so that users can navigate through submenus and other
|
|
"nested" popup windows without having to dismiss the topmost
|
|
popup.
|
|
|
|
Clients that want to dismiss the popup when another surface of
|
|
their own is clicked should dismiss the popup using the destroy
|
|
request.
|
|
|
|
The parent surface must have either an xdg_surface or xdg_popup
|
|
role.
|
|
|
|
Specifying an xdg_popup for the parent 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.
|
|
|
|
If there is an existing popup when creating a new popup, the
|
|
parent must be the current topmost popup.
|
|
|
|
A parent surface must be mapped before the new popup is mapped.
|
|
|
|
When compositors choose to dismiss a popup, they will likely
|
|
dismiss every nested popup as well.
|
|
|
|
The x and y arguments specify where the top left of the popup
|
|
should be placed, relative to the local surface coordinates of the
|
|
parent surface.
