Ah, I understand what you mean, but I meant an instance of a source widget, as in a “Child” in the widget hierarchy of the Designer. I have a widget with 3 “child” widgets in the hierarchy, all marked as “is variable”.
Is there a way to override (in “Widget1”) a function that is defined on the source widget of the “child” in the hierarchy? e.g. I have a function called “ButtonPressed”, called when the button within the source widget is pressed, the behavior of which I want to customize for each instance of the source widget within “Widget1”. Thank you so much for your answer; I should have been clearer!
