QTreeView automatic Widget Height adjustment

[mqt]

I am creating QTreeView with QStandardDataModel. The Height if the widget seems to be bigger than needed. How to fix it? Also I would like to edit the height of TreeView dynamically so that it is just enough to fit the current data / expansion state. Please help

It wont be a good idea. TreeView will be inherited from scroll area and will provide a scroll bar if the height of items is more than the height of the view.

You might try playing with QStandardItem::sizeHint

It will not be good when the contents are more. My problem is that, it comes with lot of blank area even though the contents are less. I want to avoid that space initially.When someone expands the view should become bigger upto a limit and then it scroll bar should appear.
