<interface name="xdg_popup" version="1">
<description summary="desktop-style metadata interface">
An interface that may be implemented by a wl_surface, for
implementations that provide a desktop-style popups/menus. A popup
surface is a transient surface with an added pointer grab.
<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.
An existing implicit grab will be changed to owner-events mode,
and the popup grab will continue after the implicit grab ends
(i.e. releasing the mouse button does not cause the popup to be
unmapped).
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.
The popup grab continues until the window is destroyed or a mouse
button is pressed in any other clients window. A click in any of
the clients surfaces is reported as normal, however, clicks in
other clients surfaces will be discarded and trigger the callback.
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.
The x and y arguments specify the locations of the upper left
corner of the surface relative to the upper left corner of the
parent surface, in surface local coordinates.
Clients that want to dismiss the popup when another surface of
their own is clicked should dismiss the popup using the destroy
request.
xdg_popup surfaces are always transient for another surface.
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.
