It's bug in your code (range error). You're using aHandle: System.THandle (longint) instead of LCLIntf.THandle which is of ptruint type. Best and correct usage would be to use HWND type which is what it needs to be on all platforms and widgetsets. When aHandle type is corrected, or LCLType is included with it's THandle then everything works as expected. Don't ask me my gtk2 works, in any case it's wrong on 64bit platform.
Thanks a lot. With the proper type of aHandle it works fine both with Qt and GTk2.
Maybe it was working with gtk2 because there's an additional check on handle validity but I didn't investigate further. A bug of mine is a bug of mine.
