    Description

      When creating a transparent application window, the window appears as black instead of transparent. The problem happens on Win XP and Win 7 computers. If the aero theme is set it seems to work. However setting the aero theme individually on each computer is not a solution for deployment.

      ApplicationWindow {
      visible: true
      width: 640
      height: 480
      title: qsTr("Hello World")

      color:"transparent"

      Rectangle

      { width: 150 height: 150 color:"red" }

      }
