How break pop window of StackView?

[_dmp]

I want catch poping window of StackView and break it, by user, for example.

Like this:

@import QtQuick 2.2
import QtQuick.Controls 1.1 as Controls

Controls.Stack.onStatusChanged: {
if (Control.Stack.status === Control.Stack.Deactivating)
Control.Stack.status = Control.Stack.Active; // status is read only now
}@

How make it correctly, if possible?
