QTableView row height via delegate and setRootIndex

[pmaktieh.sirhc]

Hi,

I have a QTableView with a delegate, this sets the row height of the table view, via override sizeHint:

QSize MyClass::sizeHint(const QStyleOptionViewItem &option, const QModelIndex &index) const
{
	QSize s = QItemDelegate::sizeHint(option, index);
 
	if ( s.isValid() )
		s.setHeight(20);
 
	return s;
}

QSize MyClass::sizeHint(const QStyleOptionViewItem &option, const QModelIndex &index) const
{
	QSize s = QItemDelegate::sizeHint(option, index);
	
	if ( s.isValid() )
		s.setHeight(20);

	return s;
}

To copy to clipboard, switch view to plain text mode 

This works 100%. But if I set a new root index for the tableview:

void QAbstractItemView::setRootIndex ( const QModelIndex & index )

void QAbstractItemView::setRootIndex ( const QModelIndex & index )

To copy to clipboard, switch view to plain text mode 

the row height is set to default height. The delegate is ignored! I need a fixed row height, also after a new root index!


Does anyone know, what the problem is? How can I fix this?

Thanks!
Chris

Could you post a minimal compilable example reproducing the problem?

I've found my mistake, I must call

void QTableView::resizeRowsToContents()

void QTableView::resizeRowsToContents()

To copy to clipboard, switch view to plain text mode 

after the new index has set!

...nevertheless thanks for your help!
