In my page I have a Gxt ContentPanel with a white background. However, when the user mouses over the Header of the ContentPanel, I would like the background to change colors.
I tried achieving this by using the protected addStyleOnOver method of Gxt Component, but it doesn't have any effect. Is there anything else I need to do to use that methods (I'm already sinking the ONMOUSEOVER and ONMOUSEOUT events), or a better way to change the background?
