Class RoundedBackground

java.lang.Object

ej.mwt.style.background.RoundedBackground

All Implemented Interfaces:

Background

public class RoundedBackground
extends java.lang.Object
implements Background

Draws a plain color on the background with a round corner.

Should be used in association with a RoundedBorder to:

• anti-alias its edges by using the same color,
• draw a colored border that fits its shape.

For a better rendering, the border radius must be a bit smaller than the background one.

The corner radius is stored as a char for heap optimization and therefore cannot exceed 65535.
