Cannot clear PopUp, popup_clear(..) not working on Mac

[SamSandq]

I needed to have one popup button clear and re-populate another popup button, and discovered that the popup_clear(...) does not work on Mac.

Checking the code, it's not implemented. Correct by inserting the following code in ospopup.m : ospopup_elem, at line 180:

    else if (op == ekCTRL_OP_DEL) {
        [((OSXPopUp*)popup) removeItemAtIndex: idx];
    }

This seems to do the trick, but there might be other ramifications as well.

Just wanted to comment that I ran into the popup_clear() not working on macOS issue also, and the above patch seems to have solved it. Thanks.

It would be very helpful to have the above patch incorporated into NAppGUI, to implement popup_clear() in macOS - currently I have to keep a local repo of NAppGUI with the fix applied, as my application uses popup_clear() and crashes without this fix.

Fixed in this commit: b61c5cd
Also fixed allow duplicates in PopUp for macOS.
