How to Get The QTreeWidgetItem from QTreeWidget using a QWidget

[AbhiVarma]

Hi,

I have a QTreeWidget object which has lots of QTreeWidgetItem's and some of these items have a QWidget. Now I have an QWidget object I want to get the corresponding QTreeWidgetItem that has the same QWidget without iterating through all the items in QTreeWidget?

And how does that happen? Do you perchance use QTreeWidget::setItemWidget()?

You are basically out of luck. I would expect to have to iterate. setItemWidget() does not put anything into the widget so that its item/column can be retrieved. If it's really important to have fast lookup/back mapping, you might add this information to your widget(s) e.g. via QObject::setProperty(). I don't know how easy this might be to use if you adding/removing/moving your QTreeWidgetItems.
