Text across multiple columns in one row like colspan in HTML

WolleKette

Hello at all,
I use Python and pyside6 and I have a QTreeWidget with some rows (QTreeWidgetItem) and multiple columns. The rows are organized hierarchically by which I mean that there are parent and child nodes.

Now I want to place a text in the parent nodes which go over several columns. Like colspan in html for example.

I've been looking around for ages, but haven't found anything. That can not be. Somehow I'm looking in the wrong place. Please give me a tip.

There is QTreeView::setFirstColumnSpanned(). I think that's all for a QTreeView/QTreeWidget. Otherwise have a look at https://stackoverflow.com/questions/27149733/qtreeview-merge-some-cells.

I saw the setFirstColumnSpanned Method in the documentation but I have no idea how it should work and I didn’t found examples.

When I create a new node as follows and insert it in the tree, the text is still limited to the column width.

...
node = QTreeWidgetItem(['Some very long text'])
node.setFirstColumnSpanned(True)
tree.addTopLevelItem(node)
...
 insert some child nodes
...
tree.expandAll()

Oh, just now I had an idea. The trick is to call setFirstColumnSpanned after adding the node to the tree.
Then it works.
