Member Function Documentation

void qdesigner_internal::TreeWidget::drawBranches	(	QPainter *	painter,
		const QRect &	rect,
		const QModelIndex &	index
	)			const [protected, virtual]

Draws the branches in the tree view on the same row as the model item index, using the painter given. The branches are drawn in the rectangle specified by rect.

Reimplemented from QTreeView.
