Tk_CollapseMotionEvents, Tk_QueueWindowEvent — Add a window event
to the Tcl event queue
#include <tk.h>
int
Tk_CollapseMotionEvents(display, collapse)
Tk_QueueWindowEvent(eventPtr, position)
- Display *display (in)
- Display for which to control motion event collapsing.
- int collapse (in)
- Indicates whether motion events should be collapsed or
not.
- XEvent *eventPtr (in)
- An event to add to the event queue. It is important that all
unused fields of the structure be set to zero.
- Tcl_QueuePosition position (in)
- Where to add the new event in the queue: TCL_QUEUE_TAIL,
TCL_QUEUE_HEAD, or TCL_QUEUE_MARK.
Tk_QueueWindowEvent places a window event on Tcl's internal
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 window in
rapid succession, they are collapsed by default. This behavior can
be controlled with Tk_CollapseMotionEvents.
Tk_CollapseMotionEvents always returns the previous 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.
