DESCRIPTION
Tk_QueueWindowEvent places a window event on Tcl's inter-
nal event queue for eventual servicing. It creates a
Tcl_Event structure, copies the event into that structure,
and calls Tcl_QueueEvent to add the event to the queue.
When the event is eventually removed from the queue it is
processed just like all window events.
When multiple motion events are received for the same win-
dow in rapid succession, they are collapsed by default.
This behavior can be controlled with Tk_CollapseMotion-
Events. Tk_CollapseMotionEvents always returns the previ-
ous value for collapse behavior on the display.
The position argument to Tk_QueueWindowEvent has the same
significance as for Tcl_QueueEvent; see the documentation
for Tcl_QueueEvent for details.
