[Qt-interest] Restricting Mouse Movements

[Ender EREL]

I don't know if there is an automatic way to do this but i don't think 
so. You can achieve this by following these steps:

1 - Override mouseMoveEvent(QMouseEvent* event)[1] for your widget.
2 - In the overridden mouseMoveEvent, check if the mouse position is 
outside the allowed area. If it is, set the cursor position[2] to the 
nearest position inside your area.

The widget will normally recieve mouseMoveEvents only if a mouse button 
is down by default. You can recieve mouseMoveEvents when a mouse button 
is not down by calling setMouseTracking(true)[3] on your widget.
