 @JavaBean(description="A component which can be selected or deselected.") public class JCheckBox extends JToggleButton implements Accessible An implementation of a check box -- an item that can be selected or deselected, and which displays its state to the user. By convention, any number of check boxes in a group can be selected. See How to Use Buttons, Check Boxes, and Radio Buttons in The Java Tutorial for examples and information on using check boxes.Buttons can be configured, and to some degree controlled, by Actions. Using anActionwith a button has many benefits beyond directly configuring a button. Refer to Swing Components SupportingActionfor more details, and you can find more information in How to Use Actions, a section in The Java Tutorial.Warning: Swing is not thread safe. For more information see Swing's Threading Policy. Warning: Serialized objects of this class will not be compatible with future Swing releases. The current serialization support is appropriate for short term storage or RMI between applications running the same version of Swing. As of 1.4, support for long term storage of all JavaBeans™ has been added to the java.beanspackage. Please seeXMLEncoder.- Since:
- 1.2

Method Detail- 
setBorderPaintedFlat@BeanProperty(visualUpdate=true, description="Whether the border is painted flat.") public void setBorderPaintedFlat(boolean b) Sets theborderPaintedFlatproperty, which gives a hint to the look and feel as to the appearance of the check box border.

This method fires a property changed event. Some look and feels might not implement flat borders; they will ignore this property.- Parameters:
- b-- truerequests that the border be painted flat;- falserequests normal borders

- getUIClassIDin class- JToggleButton
- Returns:
- the string "CheckBoxUI"

paramStringprotected String paramString() Returns a string representation of this JCheckBox. This method is intended to be used only for debugging purposes, and the content and format of the returned string may vary between implementations. The returned string may be empty but may not benull. specific new aspects of the JFC components.- Overrides:
- paramStringin class- JToggleButton
- Returns:
- a string representation of this JCheckBox.
 
 - 
getAccessibleContext@BeanProperty(bound=false, expert=true, description="The AccessibleContext associated with this CheckBox.") public AccessibleContext getAccessibleContext() Gets the AccessibleContext associated with this JCheckBox. For JCheckBoxes, the AccessibleContext takes the form of an AccessibleJCheckBox. A new AccessibleJCheckBox instance is created if necessary.- Specified by:
- getAccessibleContextin interface- Accessible
- Overrides:
- getAccessibleContextin class- JToggleButton
- Returns:
