问题 This has been bugging me for more than two days now, so i thought i should ask. I am using Qt 4.5.3 (compiled with VC2008) on Win7.

问题 I have a QT main window and on top of this I want to add a widget ( containing buttons), as similar to image below. If I add a dock widget , it is added in separate row, but not added as overlay on existing main window. Any inputs ? 回答1: The easiest is to set your overlay widget's parent to be the main window. But because it will not be in any layout you have to take care of its geometry yourself. In case you want to have multiple overlays, the last added will be the top most. #include
