Moving QTreeWidgetItem Up and Down in a QTreeWidget

[Staakman]

Hi,

I want to be able to swap two QTreeWidgetItem positions in a QtreeWidget.
With other words move items up and down 1 position in a QtreeWidget.

After searching for hours online I just can't find a proper solution.
Not a single one of them works.
Have to add to this that I'm very new to QT.

Does anyone have a solution to my problem?

Thanks in advance.

You get the parent item, then you call its indexOfChild method to determine the index if your current item, then call takeItem() and then insertItem with either index - 1 or index + 1

Worked as a charm!
Thank you very much.

QTreeWidgetItem* item = this->currentItem();
int row  = this->currentIndex().row();
if (item && row > 0)
{
	QTreeWidgetItem* parent = item->parent();
	int index = parent->indexOfChild(item);
	QTreeWidgetItem* child = parent->takeChild(index);
	parent->insertChild(index-1, child);
	parent->setExpanded(true);
	child->setExpanded(true);
}

QTreeWidgetItem* item = this->currentItem();
int row  = this->currentIndex().row();
if (item && row > 0)
{
	QTreeWidgetItem* parent = item->parent();
	int index = parent->indexOfChild(item);
	QTreeWidgetItem* child = parent->takeChild(index);
	parent->insertChild(index-1, child);
	parent->setExpanded(true);
	child->setExpanded(true);
}
