bool QWidgetResizeHandler::eventFilter	(	QObject *	,
		QEvent *
	)		[protected, virtual]

Filters events if this object has been installed as an event filter for the watched object.

In your reimplementation of this function, if you want to filter the event e, out, i.e. stop it being handled further, return TRUE; otherwise return FALSE.

Example:

    class MyMainWindow : public QMainWindow
    {
    public:
        MyMainWindow( QWidget *parent = 0, const char *name = 0 );

    protected:
        bool eventFilter( QObject *obj, QEvent *ev );

    private:
        QTextEdit *textEdit;
    };

    MyMainWindow::MyMainWindow( QWidget *parent, const char *name )
        : QMainWindow( parent, name )
    {
        textEdit = new QTextEdit( this );
        setCentralWidget( textEdit );
        textEdit->installEventFilter( this );
    }

    bool MyMainWindow::eventFilter( QObject *obj, QEvent *ev )
    {
        if ( obj == textEdit ) {
            if ( e->type() == QEvent::KeyPress ) {
                QKeyEvent *k = (QKeyEvent*)ev;
                qDebug( "Ate key press %d", k->key() );
                return TRUE;
            } else {
                return FALSE;
            }
        } else {
            // pass the event on to the parent class
            return QMainWindow::eventFilter( obj, ev );
        }
    }

Notice in the example above that unhandled events are passed to the base class's eventFilter() function, since the base class might have reimplemented eventFilter() for its own internal purposes.

Atención:

If you delete the receiver object in this function, be sure to return TRUE. Otherwise, Qt will forward the event to the deleted object and the program might crash.
