Class DefaultMutableThemeStyle

java.lang.Object

com.googlecode.lanterna.graphics.DefaultMutableThemeStyle

All Implemented Interfaces:

ThemeStyle

public class DefaultMutableThemeStyle
extends java.lang.Object
implements ThemeStyle

This basic implementation of ThemeStyle keeps the styles in its internal state and allows you to mutate them. It can be used to more easily override an existing theme and make small changes programmatically to it, see Issue409 in the test section for an example of how to do this.
