Determining CHECK Button Status

Proper interface design sometimes requires you to programmatically interact with the state of a button. An example is when you need to set a button’s state to checked, depending upon a value retrieved from a database or upon the occurrence of some other condition in the application

How do I do that?

The properties of Button are accessible using get and set methods in the JavaBeans paradigm. To programmatically cause a button to be checked, use this code:

Note

Pass false to setSelection( ) to uncheck the button.

b1.setSelection(true);

Use getSelection( ) to determine the current state of a variable:

boolean selected = b1.getSelection( );
