Hi guys,
I use a subclass of QAbtractItemModel and QTreeView to edit big xml files. It works fine, but today I noticed, that the app gets very slow, if the xml file is too big.
Then I debugged a little bit and noticed, that the index method i called everytime. Even if I move the mouse over the view.
What's wrong? What can I do. There are 400 items and it is slow. What, if there are 5000 items?
Please help me...thanks
