QListWidget, prompt before currentItemChanged signal
-
@jsulm, as far as I can see with a breakpoint on the first line in the select function, no it isn't.
@SPlatten Well, then find out why not.

@SPlatten How should I know?!
You did not even tell us to what signal select() is connected! -

@jsulm , I'm not asking out specifically....looking at the class, its derived from QItemSelectionModel:
https://doc.qt.io/qt-5/qitemselectionmodel.html#signals@SPlatten said in QListWidget, prompt before currentItemChanged signal:
QItemSelectionModel
OK, did not notice this

@Christian-Ehrlicher , thank you, I can see that the select slot is getting called, but it appears that it is being called after the currentItemChanged signal, which is wrong isn't it?

Why? Is it written down somewhere? And from my pov a cell has to be the current one until the selection can change.

@Christian-Ehrlicher , the intention is that when the user tries to make a new selection, an interim step checks that its ok to allow the change, by checking other content using the slot...it can then allow or disallow the selection.

@Christian-Ehrlicher , @jsulm , I think I've been going down a rabbit hole in trying to implement this model, when all I actually need to do is move the test for change into the slot and then if I don't want to allow the selection change assign QListWidgetItem* pobjCurrent to QListWidgetItem* pobjPrevious.
