[Qt-interest] Filtering Mouse events in QT

[Zaid Amir]

Hi

I have tried using an event filter but a drag event from QWebView does not
seem to occur when I drag the mouse to select text or pages from a webpage.
Most of the other mouse events seems to propagate from webview as I've been
able to filter out MouseButtonPress, MouseButtonRelease and MouseMove with
no problem. However, DragEnter, DragLeave and DragMove are not generated or
not grabbed by my event filter.

Any suggestions.

Hi Zaid,

I think a good place to start looking is the Mouse Tracking in QWidget 
(which will always trigger mouseMoveEvents on your widget, no matter if 
a mouse button was pressed on it or not) and the Drag&Drop functionality 
embedded in Qt: http://qt.nokia.com/doc/4.6/dnd.html

I don't think filtering the events is the best approach here, but other 
may prove me wrong.

Kind regards,

Jroen
