The new Release 20.03 is out! You can download binaries for Windows and many major Linux distros here .
I can select icon from the icon property, but after compiled, the Frame's icon still using the stand blank icon.
Is that the only way to set the frame icon is to set it inside the frame's constructor by manual code as stated in http://forums.codeblocks.org/index.php/topic,5788.msg44389.html#msg44389?
