How to ensure a widget is not resizable?

I've made a widget and UI for that widget and I've really just run into one problem: Is it possible to make the widget non-resizable? Although tedious, I like using scale to script my UI and it doesn't look amazing when you resize the parent widget. I've searched around about this, but there seems to be no property, or event, to resize or to tell when a user is resizing the widget. I'd usually show code I tried but I haven't encountered a way to do this yet. Any help is appreciated, even if you tell me it's not possible. Thank you :)
