I want to call a function after a change in a QTreeView.

[developer_96]

How can i achive to call a function or doing something after a change in a QTreeView.
For Example:

if(change in QtreeView)
{
s = 3;
}

So how can I say that something is changed.

The model from the view has some nice signals for this.

@Christian-Ehrlicher thank you. But the problem is i already use a signal for an button that is triggered.
So how can i achive to say that the button can be only clicked after a change?
Is it possible to use the signal as a condition?

Enable the button after the model emitted a change signal.
