Package ej.mwt.style.background

Class 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 (using same color, corner radius and border thickness) to:

    • draw the border,
    • anti-alias the corner edges (blending color with background).

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

        isTransparent in interface Background
        Parameters:
        width - the width of the background.
        height - the height of the background.
        Returns:
        true if the background is transparent, false otherwise.
