Issues with Q3DockWindow and Q3DockArea

We are using the Q3Support library while porting our appplication from Qt version 3.0.4 to Qt version 4.8.0 and have some issues with the model browser (which uses Q3DockArea & Q3DockWindow).

In the new version of Qt that we are moving to (4.8.0), there are 2 cases in which the "hideEvent" of the QDockWindow class is called, which results in hiding the dock window.

These cases are:

Double clicking the title bar of the dock window
Dragging the dock window in the dock area

For both these actions, the exepectation is that the dock window widget docks to the docking area.

However, in 4.8.0, "hideEvent" of QDockWindow is called, hiding the dock window.

This was not the behavior in Qt 3.0.4.
