Thanks for the suggestion. I’ll add these four properties to GroupBox, available through the Inspector and in code:
- Border colour.
- Border thickness, including zero to hide it.
- Corner radius, including zero for square corners.
- Caption text colour.
The existing appearance will remain the default.
I won’t add the separate frame around the caption. That would introduce another set of border and spacing options, and I’d prefer to keep the caption simple.
