expanded description for "radius" #4482
Conversation
I originally understood the wording around "65535 = pill shaped widget (true circle..." in a way that setting radius to 65535 always gives you a circle, also for widgets that (obviously) have way smaller widths and heights. Working with it a bit I realised it's not that straightforward, and that setting a radius in line with what is set for width/height is the way to go anyway. So I decided to expand the description a bit.

328-328: Excellent clarification of the radius parameter behavior!The updated documentation correctly explains that setting radius to 65535 creates a pill-shaped widget, and only results in a true circle when the widget has equal width and height with radius set to half of those dimensions. This prevents potential misunderstandings about widget shapes.
Consider adding a brief example to make it even clearer:
- radius** (*Optional*, uint16): The radius to be used to form the widget's rounded corners. 0 = no radius (square corners); 65535 (max) = pill shaped widget (true circle if it has same width and height, radius then should be set to half the width/height). + radius** (*Optional*, uint16): The radius to be used to form the widget's rounded corners. 0 = no radius (square corners); 65535 (max) = pill shaped widget (true circle if it has same width and height, radius then should be set to half the width/height). For example, a 100x100 widget with radius=50 will be perfectly circular.

328-328: LGTM! Documentation improvement enhances clarity.The updated description correctly explains the relationship between the radius parameter and widget dimensions. This helps prevent the misconception that setting radius to 65535 always results in a circular widget.
