[Solved]Can QTreeWidget Really be edited?
I'm now puzzled about QTreeWidget.
The doc says, QTreeWidget inherits from QAbstractItemView.I want the QTreeWidgetItem in a QTreeWidget to be editable when users double click the mouse on the item.
But When I run the program,double click seems of no use.The item is still read-only and can't be modified.
Does anyone solve this problem before? Is the only way to use Model/View menthod & QTreeView instead?
I'm sorry to trouble you.But I just found the key to the problem.
It is about the QTreeWidgetItem.When you want to modify a item in QTreeWidget or others, set the edittriggers is not enough.
Every item to be added in the widget must set theis flags first.
And that may work.
