U++ forum: Welcome to the forum

Edit: Never mind, the error seems to be fixed when I make TopPanel and BottomPanel inherit from ParentCtrl instead of Ctrl.

Hi,
In the below example, if you hover over the option, it's background becomes black.
If you push the button, which changes the text of the label, the background of the label becomes black.
