Jbutton events in java

Class JButton

Buttons can be configured, and to some degree controlled, by Action s. Using an Action with a button has many benefits beyond directly configuring a button. Refer to Swing Components Supporting Action for more details, and you can find more information in How to Use Actions, a section in The Java Tutorial.

See How to Use Buttons, Check Boxes, and Radio Buttons in The Java Tutorial for information and examples of using buttons.

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.beans package. Please see XMLEncoder .

Constructor Summary

Method Summary

Gets the value of the defaultButton property, which if true means that this button is the current default button for its JRootPane .

Overrides JComponent.removeNotify to check if this button is currently set as the default button on the RootPane , and if so, sets the RootPane ‘s default button to null to ensure the RootPane doesn’t hold onto an invalid button reference.

Sets the defaultCapable property, which determines whether this button can be made the default button for its root pane.

updateUI

getUIClassID

@BeanProperty(bound=false, expert=true, description=»A string that specifies the name of the L&F class.») public String getUIClassID ()

isDefaultButton

@BeanProperty(bound=false, description=»Whether or not this button is the default button») public boolean isDefaultButton ()

Gets the value of the defaultButton property, which if true means that this button is the current default button for its JRootPane . Most look and feels render the default button differently, and may potentially provide bindings to access the default button.

isDefaultCapable

setDefaultCapable

@BeanProperty(visualUpdate=true, description=»Whether or not this button can be the default button») public void setDefaultCapable (boolean defaultCapable)

Sets the defaultCapable property, which determines whether this button can be made the default button for its root pane. The default value of the defaultCapable property is true unless otherwise specified by the look and feel.

removeNotify

Overrides JComponent.removeNotify to check if this button is currently set as the default button on the RootPane , and if so, sets the RootPane ‘s default button to null to ensure the RootPane doesn’t hold onto an invalid button reference.

paramString

Returns a string representation of this JButton . 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 be null .

getAccessibleContext

@BeanProperty(bound=false, expert=true, description=»The AccessibleContext associated with this Button.») public AccessibleContext getAccessibleContext ()

Gets the AccessibleContext associated with this JButton . For JButton s, the AccessibleContext takes the form of an AccessibleJButton . A new AccessibleJButton instance is created if necessary.
