Subject: [PATCH] wayland: do not leak shortcut inhibit data
|
||||
|
||||
We would free the shortcut inhibit data only when the client destroys
|
||||
its request, which is not the case when the clients itself is
|
||||
destroyed, leading to a leak of the shortcut inhibit data.
|
||||
|
||||
Free the data on resource destruction instead, and simply destroy the
|
||||
resource on destroy request.

Subject: [PATCH] wayland: Keep the inhibit shortcut dialog
|
||||
|
||||
On Wayland, the grab()/ungrab() in gtk+/gdk are wired to the shortcut
|
||||
inhibitor mechanism, which in turn shows the dialog, which can take
|
||||
focus away from the client window when the dialog is shown.
|
||||
|
||||
If the client issues an ungrab() when the keyboard focus is lost, we
|
||||
would hide the dialog, causing the keyboard focus to be returned to the
|
||||
client surface, which in turn would issue a new grab(), so forth and so
|
||||
on, causing a continuous show/hide of the shortcut inhibitor dialog.
|
||||
|
||||
To avoid this issue, keep the dialog around even if the shortcut inhibit
|
||||
is canceled by the client, so that the user is forced to make a choice
|
||||
that we can reuse on the next request without showing the dialog again.
|
||||
|
||||
Instead of hiding the dialog when the shortcut inhibitor is destroyed by
|
||||
the client, we simply mark the request as canceled and do not apply the
|
||||
user's choice.
