Hi everybody
when i compile and run code below, I get my internal frames to
display the screen portion, but the internal frames DON'T show the
title, closable, minimize, itd..it doesnt look like an internal
frames...
i tried calling super("title", true, true, true, true);
in the sourceWarp constructor but it doesnt change anything...does
anyone have indea what can i do...extremelly thankful
