.SH DESCRIPTION
.PP
Sx_GrabMouse is functionally almost identical to the XGrabMouse
routine, except that it grabs the mouse for a particular window
instead of a particular client.  After Sx_GrabMouse is called,
all future mouse events will only go to \fIwindow\fP.  The
ButtonPressed, ButtonReleased, EnterWindow, LeaveWindow, MouseMoved,
LeftDownMotion, MiddleDownMotion, and RightDownMotion bits of
\fImask\fP temporarily override the corresponding bits in any mask
previously passed to XSelectInput or Sx_HandlerCreate;  other bits
in \fImask\fP are ignored.
.PP
If one of the above-mentioned events occurs then Sx_HandleEvent
will send the event to \fIwindow\fP instead of the window that
would otherwise have received the event.  The difference between
Sx_GrabMouse and XGrabMouse is that XGrabMouse will only redirect
events for windows that don't have handlers declared by this
client through XSelectInput or Sx_HandlerCreate;  for other windows
in the same client the events are not redirected.  Sx_GrabMouse provides
the additional functionality of redirecting events from this client's
windows.
.PP
Sx_UngrabMouse undoes the effect of a previous call to Sx_GrabMouse,
restoring the mouse to normal operation.  Sx_UngrabMouse is invoked
automatically if a previous grab is still in effect when Sx_GrabMouse
is invoked.
.PP
These procedures call XGrabMouse and XUngrabMouse;  the caller should
not call XGrabMouse or XUngrabMouse directly if it is using Sx_GrabMouse.
