Qt Adjust TreeWidget Row

[ruisebastiao]

i have a QTreeWidget with the following structure

@ Row 1 --> QPushButton
|
|--> Child 1 --> QFrame
|
|->QVBoxLayout
|
|->QListView@

The number of rows and thus the size of QListView can change, so i implemented a QStyledItemDelegate to set the sizehint according to size of QListView. My problem is that when i insert a row in QListView the QTreeWidget does not update the size of the row with the new sizehint value, if i use updateGeometry() the sizehint in the delegate is not called, but if i collapse and axpand the item then the row gets resized. how can i force the QTreeWidget to resize the row according to the sizehint without having to collapse and expand the root item, Thanks

Ok, i have to call QTreeView::doItemsLayout()
