That looks like a good idea and should be easy to implement. Regards, Ulrich Doug Bell wrote:
You don't actually have to create all items at once with the tree-widget item-based approach. You can just create the visible items (that have open parents). Then create a method that loads children on demand and connect it to the itemExpanded(QTreeWidgetItem*) signal. To get the "+" button to display properly, you can add a single dummy child item to each closed parent item, then delete it when actually loading the real children. Doug.
