How do I make a component that when instantiated allows only the degrees of freedom I want?
For example the 48px high blue bordered white rectangle has a 48px square constrained left & top-bottom and that has a 24px icon, constrained to the centre of the blue square. The text lable is changeable, so the width of the white rectangle should be user settable but the height of the white rectangle and the blue square MUST remain 48px. I can’t see any way to do this. It seems like a basic feature but as far as I can see, it’s not there!
