From the Present extension specification: An event context is associated with a specific window; using an existing event context with a different window generates a Match error. If eventContext specifies an existing event context, then if eventMask is empty, PresentSelectInput deletes the specified context, otherwise the specified event context is changed to select a different set of events. If eventContext is an unused XID, then if eventMask is empty no operation is performed. Otherwise, a new event context is created selecting the specified events. Without this change, there's no way for a client to explicitly change or destroy an existing event mask entry. Trying to do so as specified above would just result in a protocol error. v2: (Keith Packard) * Use dixLookupResourceByType instead of walking window_priv->events * Return BadMatch if the existing event context is associated with a different window or client * Call LEGAL_NEW_RESOURCE again when creating a new event context * Drop invalid "leak fix" Signed-off-by: Michel Dänzer <michel.daenzer@amd.com> Signed-off-by: Keith Packard <keithp@keithp.com> Reviewed-by: Keith Packard <keithp@keithp.com> Reviewed-by: Kenneth Graunke <kenneth@whitecape.org>
X Server
The X server accepts requests from client applications to create windows,
which are (normally rectangular) "virtual screens" that the client program
can draw into.
Windows are then composed on the actual screen by the X server
(or by a separate composite manager) as directed by the window manager,
which usually communicates with the user via graphical controls such as buttons
and draggable titlebars and borders.
