Hello,
with a simple test - see the code snippet below - I successfully receive
XI_Enter notifications for my window, but XI_Leave are missed. Are there
any problems with the test, or something else is wrong?
----
display = XOpenDisplay(NULL);
root = RootWindow(display, 0);
window = XCreateSimpleWindow(display, root,
100, 100, 320, 240,
BlackPixel(display, 0),
WhitePixel(display, 0));
eventmask.deviceid = XIAllMasterDevices;
eventmask.mask_len = sizeof(mask);
eventmask.mask = mask;
XISetMask(mask, XI_Enter);
XISetMask(mask, XI_Leave);
XISelectEvents(display, window, &eventmask, 1);
XMapWindow(display, window);
XSync(display, True);
while (1) {
XNextEvent(display, &xev);
if ((xev.xcookie.type == GenericEvent) &&
(xev.xcookie.extension == xinput_opcode) &&
XGetEventData(display, &xev.xcookie)) {
switch (xev.xcookie.evtype) {
case XI_Enter:
fprintf(stderr, "XI_Enter\n");
break;
case XI_Leave:
fprintf(stderr, "XI_Leave\n");
break;
}
XFreeEventData(display, &xev.xcookie);
}
}
----
The problem is reproducible both with a single master device and with
multiple ones. If I modify the test to listen for regular EnterNotify
and LeaveNotify, these are received correctly (but XI_Leave is still
missed).
Any ideas?
Thanks,
Artem
