Setting background color breaks windowsvista style



  • I have a Qt application consisting of a QTreeView inside a QMainWindow. The application works fine until I try to use a stylesheet to set the QTreeView's background color:

    @QTreeView {
    background-color: gray
    }@

    The background color does indeed change. But if I try to move or resize the window with the mouse, the application blocks. It looks as though the mouse is being grabbed and not released, because if I hit Ctrl-Alt-Del to get Windows' attention, and then hit Esc, it unblocks the application.

    Has anybody out there had similar problems? I am using Qt 5.0.0 on Windows 7.

    Thanks...



  • A new element: I only have this problem with the default style, which would appear to be "windowsvista"...
