Hi, Peter,
following your suggestion, I have verified `xinput --test-xi2` works
correctly and reports all the XI_Leave events. After another half an
hour I have finally found the problem: the eventmask.mask was too small,
so XI_Leave (which corresponds to 1 << 8) was skipped, while XI_Enter (1
<< 7) was handled fine.
Thanks,
Artem

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).
weird. I copy/pasted your code (no changes, just added the missing
declarations and one missing param to XCreateSimpleWindow) I'm getting
events just as required.
do you see enter/leave events with "xinput --test-xi2"?
is the value of xinput_opcode off by any chance? try to hardcode it, you can
get the value from "xdpyinfo -ext XInputExtension | grep opcode"
Cheers,
Peter
