[QT3] QListView and Key_Delete - doesn't work?

[InZone]

Hi there,

I am trying to get a simple thing running: alowing the user to delete a listviewitem with the "del" key. But it seems that the listview doesn't get that key. Some other keys I tried are not a problem....

It seem that something is catching my keay away?

Any help is welcome

Thanks in advance

void CEngravingDialog::keyPressEvent( QKeyEvent *event )
{
if( listViewElements->hasMouse() )
	{
		switch( event->key() )
		{
		case Key_Delete:																//Delete if item in listview is selected
			ButtonDelete();
			break;
		default:
			QWidget::keyPressEvent( event );
		}
	}
}

void CEngravingDialog::keyPressEvent( QKeyEvent *event )
{
if( listViewElements->hasMouse() )
	{
		switch( event->key() )
		{
		case Key_Delete:																//Delete if item in listview is selected
			ButtonDelete();
			break;
		default:
			QWidget::keyPressEvent( event );
		}
	}
}

To copy to clipboard, switch view to plain text mode

you are catching the kePressEvent on the listView through the dialog.
Did you turn on global mouse grabbing?
Try doing the same as you did but with the listView directly.

I made such an option for myself

I subclassed QListView and then reimplemented the keyPressEvent..

Like this...

void MyListView::keyPressEvent( QKeyEvent *event )
{
    QListViewItemIterator it(this);
 
    if ( (event->key() == Qt::Key_Delete) )
    {   
        while ( it.current() ) 
        {
            if( it.current()->isSelected() )
            {
               ButtonDelete( it.current() );
               break;
            }
            else
            {
               it++;
            }
        }
    }
 
    QListView::keyPressEvent(event);
}

void MyListView::keyPressEvent( QKeyEvent *event )
{
    QListViewItemIterator it(this);

    if ( (event->key() == Qt::Key_Delete) )
    {   
        while ( it.current() ) 
        {
            if( it.current()->isSelected() )
            {
               ButtonDelete( it.current() );
               break;
            }
            else
            {
               it++;
            }
        }
    }

    QListView::keyPressEvent(event);
}

I think this works fine for single selection
It's a different approach than yours, but it's an idea
