voidzxdg_popup_v6_t::configure(int32_tx,int32_ty,int32_twidth,int32_theight,boolpost=true)
configure the popup surface
Parametersx x position relative to parent surface window geometry
y y position relative to parent surface window geometry
width window geometry width
height window geometry height
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.

std::function<void()>&zxdg_popup_v6_t::on_destroy()
remove xdg_popup interface 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, a protocol error will be sent.

std::function<void(seat_t,uint32_t)>&zxdg_popup_v6_t::on_grab()
make the popup take an explicit grab
Parametersseat the wl_seat of the user event
serial the serial of the user event
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.
The parent of a grabbing popup must either be another xdg_popup with an active explicit grab, or an
xdg_popup or xdg_toplevel, if there are no explicit grabs already taken.
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.

popup interaction is done 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.

Post 'not enough memory' error to the client
If the compositor has not enough memory to fulfill a certail request of the client, this function can be
called to notify the client of this circumstance.
