Detailed Description

Definition of a rounded rectangle shape.

When drawing a rounded rectangle it doesn't get blended on the surface but replaces the pixels instead. A blitting flag might be added later if needed.

Key	Type	Default	Description
corner_radius	f_unsigned	0	The radius of the rectangle's corners.
border_thickness	unsigned	0	The thickness of the border; if the thickness is zero it's not drawn.
border_color	color	""	The color of the border; if empty it's not drawn.
fill_color	color	""	The color of the interior; if omitted it's not drawn.
debug	string	""	Debug message to show upon creation; this message is not stored.

border_color_

typed_formula<color_t> gui2::round_rectangle_shape::border_color_

private

The border color of the rounded rectangle.

If the color is fully transparent the border isn't drawn.
