+    \class HbTransparentWindow
+    \brief The HbTransparentWindow class provides a easy way to create 
+    transparent area to UI.
+
+    A transparent window is transparent area in the UI which will show
+    underlying content through. The HbMainWindow needs to be constructed
+    with Hb::WindowFlagTransparent attribute to get the hole working. 
+    
+    Transparent window will erase all the pixels in the UI underneath the 
+    widget. You can place content on top of transparent window normally.
+    
+    This widget is meant to be used when developer has own window surface
+    running underneath the UI and this surface should be show through the 
+    hole in the UI e.g. video playback through own surface or HW accelerated 
+    3D content in own surface.
