Splitter between items in QTreeView

[flammmable]

I want to resize an items height in a QTreeView separately for each item. Is there an easy way to make splitters between each items in a QTreeView?

[Christian Ehrlicher]

No, you have to do it on your own - maybe by subclassing QTreeView but I don't think it's that easy...

Thank you. It's sad.

Hi,

Can you explain your use case in more details ?
Would resizing rows be enough ?

[VRonin]

Yeah, I think OP wants to do what QHeaderView::setResizeMode(QHeaderView::Interactive) does but on rows of a treeview

@SGaist Would resizing rows be enough ?
Yes it will de enough.
Now I try to use a QTreeWidget and itemAt to define an item under a mouse cursor. Also I try to redefine mouseMoveEvent in a QTreeWidgetItem but still have not reach a success. Can't write a right constructors fo MyTreeWidgetItem. I will be grateful for any advice

@flammmable The QTreeWidgetItem have not a mouseMoveEvent. Hmm...

[SGaist]

Because items have no visual representation, that's done by the delegate.

If you want to go that way, you have to re-implement the mouseXXXEvents of your QTreeWidget.

As an alternative, you might want to add a vertical QHeaderView like QTableView.
