@SGaist It worked. Thank you so much.

@MjrWilson Wow! Typical Visual Studio. One of the many reasons I try to avoid MSVC as a compiler. I've had similar issues at work lately, installing an older win api completely ruined 3 versions of visual studio to the point of reinstalling and having to manually clean the registry. Go Microsoft! Oh well as a MSFT stock owner at least other people like them even if I don't. ;) Glad you got it fixed. :)

@Vinod-Kuntoji No not working , rubberBand->setPalette(Qt::transparent); removes the color from borders also..

Thank you Gaist ! I'm noobcake here this was my first question.
