QListView & QStandardItemModel check text before editing row

I want to check the text of a row in QListView before the user is editing it. If it doesn't fit a pattern, I don't want to accept it.

Currently I have a QListView and QStandardItemModel. I can easily add and remove items via the QStandardItemModel. I also set the model of the list view.

Are there some delegates or event function(s) on the list or the model for editing?

Solution

  • you can overload data() and setData() functions from QStandardItemModel, then when user tries to edit item your setData will be called with Qt::EditRole and there you can do your processing.
