Class ToggleButton

    Direct Known Subclasses:
    RadioButton
    public class ToggleButton
extends ButtonBase
implements Toggle
    A ToggleButton is a specialized control which has the ability to be selected. Typically a ToggleButton is rendered similarly to a Button. However, they are two different types of Controls. A Button is a "command" button which invokes a function when clicked. A ToggleButton on the other hand is simply a control with a Boolean indicating whether it has been selected.

    ToggleButton can also be placed in groups. By default, a ToggleButton is not in a group. When in groups, only one ToggleButton at a time within that group can be selected. To put two ToggleButtons in the same group, simply assign them both the same value for ToggleGroup.

    Unlike RadioButtons, ToggleButtons in a ToggleGroup do not attempt to force at least one selected ToggleButton in the group. That is, if a ToggleButton is selected, clicking on it will cause it to become unselected. With RadioButton, clicking on the selected button in the group will have no effect.

    Example:

    
 ToggleButton tb1 = new ToggleButton("toggle button 1");
 ToggleButton tb2 = new ToggleButton("toggle button 2");
 ToggleButton tb3 = new ToggleButton("toggle button 3");
 ToggleGroup group = new ToggleGroup();
 tb1.setToggleGroup(group);
 tb2.setToggleGroup(group);
 tb3.setToggleGroup(group);

    MnemonicParsing is enabled by default for ToggleButton.
