* don't disable mouseTracking for a widget while using auto-hide for it.
*
* When disabling auto-hide, mouseTracking will be disabled, so if you need
* mouseTracking after disabling auto-hide, you have to reenable
* mouseTracking.

* If you want to use auto-hiding for widgets that don't take focus, e.g.
* a QCanvasView, then you have to pass all key-events that should trigger
* auto-hiding to autoHideEventFilter().

* KCursor doesn't get those events.
*
* In this case, you need to call setAutoHideCursor( widget, true, true );
* to tell KCursor not to install an eventFilter. Then you call this method
* from the beginning of your eventFilter, for example:
* \code
* edit = new KEdit( this, "some edit widget" );
* edit->installEventFilter( this );
* KCursor::setAutoHideCursor( edit, true, true );
*
* [...]
*
* bool YourClass::eventFilter( QObject *o, QEvent *e )
* {
* if ( o == edit ) // only that widget where you enabled auto-hide!
* KCursor::autoHideEventFilter( o, e );
*
* // now you can do your own event-processing
* [...]
* }
* \endcode
*
* Note that you must not call KCursor::autoHideEventFilter() when you
* didn't enable or after disabling auto-hiding.
