Ok. I'm getting there. You want code like this:
handler() {
static Time time_released;
static unsigned int last_key_pressed;
static unsigned int last_state_pressed;
switch (event) {
case FL_KEYPRESS:
{
if (!ev) break;
XKeyEvent * xke = reinterpret_cast<XKeyEvent *>(ev);
if (xke->time - time_released < 25 // should perhaps be tunable
&& xke->state == last_state_pressed
&& xke->keycode == last_key_pressed) {
// purge events
if (XEventsQueued(fl_get_display(), QueuedAlready) > 0)
waitForX(true);
break;
}
// Go on to handle the key press and dispatch it to workAreaKeyPress
...
break;
}
case FL_KEYRELEASE:
if (!ev) break;
time_released = ev->xkey.time;
last_key_pressed = ev->xkey.keycode;
last_state_pressed = ev->xkey.state;
break;
}
}
Am I there?
