QTreeWidget with checkboxes
Hello,
I have a QTreeWidget without Checkboxes. Now I want to program a QDialog which contains the same QTreeWidget, but all items shall have a checkbox.
I tried 2 ways, but none of them was successful:
1. Create a new QTreeWidget and call setModel() with the Model of the first tree and then setFlags(Qt::ItemIsUserCheckable). But no CheckBox is visible.
2. Create a new QTreeWidget and insert a QTreeWidgetItem::clone() of the top level items of the first tree.
Then also setFlags(Qt::ItemIsUserCheckable). But no CheckBox is visible.
Does anybody have an idea?
Alex
