QTableWidget NW corner header item?

[jtaylor108]

Does anyone know if there is there any way to format the NW corner button using a stylesheet? Setting the following style sheet on the NW corner button in my CTableWidget constructor doesn't seem to do anything:

CTableWidget::CTableWidget( QWidget* parent ):
	QTableWidget( parent )
{
	QList< QAbstractButton* > buttons = qFindChildren< QAbstractButton* >( this );
	for ( int i=0; i<buttons.size(); ++i )
	{
		buttons[i]->setStyleSheet( "QWidget{ background-color:red; }" );
	}
}

CTableWidget::CTableWidget( QWidget* parent ):
	QTableWidget( parent )
{
	QList< QAbstractButton* > buttons = qFindChildren< QAbstractButton* >( this );
	for ( int i=0; i<buttons.size(); ++i )
	{
		buttons[i]->setStyleSheet( "QWidget{ background-color:red; }" );
	}
}

To copy to clipboard, switch view to plain text mode 

I can paint the button myself using an event filter, but it doesn't seem like an end user can modify the appearance.

TIA,
