Have you implemented a correct flags() function for your model? Same for setData()? Have you tried your model with the qmodeltest program to check for other common mistakes?

Hi quadbyte,

did you try whether your model is editable, without your custom delegate?
That could deliver a first idea, where to search for the bug.

@ZapB, I check yours points.
@Gerolf,
You are correct Gerolf, I was not clear in my initial mail, but my Model seems to be not editable (even without custom Delegate).

I read the Qt doc to see how to make a Model editable…

Thanks a lot Guys for you help

Let me give you a hint:

an editable model [doc.qt.nokia.com]

The points are the method flags and setData.
