Check Boxes

Check Boxes

The appearance of a checkbox is platform dependant, but usually shows a square followed by some text.

The user clicks on the square to select or unselect the option and can check or uncheck as many boxes as they wish.

Use the JCheckbox class to create a checkbox.
Here are a few useful methods that belong to the JCheckbox class:

JCheckbox(String text) - create a checkbox with the passed-in text as the label.

JCheckbox(String text, boolean on) - create a checkbox with the passed-in text as the label. If on is true, the the checkbox is selected. If on is false, the checkbox is not selected. (Note this is 1.1 only.)

String getLabel() - returns a string containing the checkbox's label.

boolean getState() - returns true if the check box is selected, false if it is not.

You can create the check box, then add it:


JCheckbox applebox = new Checkbox("apples", false);
getContentPane().add(applebox);

You can also instantiate the object and add it at the same time like the
Gui2 example.
