QTreeWidget and eventFilter

[luoyes]

I placed a QTreeWidget on a QDialog. And I want to get QTreeWiget's mouse press event,so I use eventFilter like this:
in QDialog's construction

ui.m_pTreeWidget->installEventFilter( this );

ui.m_pTreeWidget->installEventFilter( this );

To copy to clipboard, switch view to plain text mode 

in the eventFilter() function:

bool ***::(QObject *pTarget, QEvent *pEvent)
{
	if( pTarget == ui.m_pTreeWidget )
	{
		if( pEvent->type() == QEvent::MouseButtonPress )
		{
			return false;
		}
	}
	return QDialog::eventFilter( pTarget, pEvent );
}

bool ***::(QObject *pTarget, QEvent *pEvent)
{
	if( pTarget == ui.m_pTreeWidget )
	{
		if( pEvent->type() == QEvent::MouseButtonPress )
		{
			return false;
		}
	}
	return QDialog::eventFilter( pTarget, pEvent );
}

To copy to clipboard, switch view to plain text mode 

But I can't get the mouse press event,why?
Thanks a lot !
