public abstract class AbstractButton
extends JComponent
implements ItemSelectable, SwingConstants

Defines the common behaviors for the JButton, JToggleButton, JCheckbox, and the JRadioButton classes.

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. A future release of Swing will provide support for long term persistence.

Constructor Detail

AbstractButton

public AbstractButton()
Method Detail

getText

public String getText()
Returns the button's text.
See Also:
setText(java.lang.String)

setText

public void setText(String text)
Sets the button's text.
Parameters:
t - the string used to set the text
See Also:
getText()

isSelected

public boolean isSelected()
Returns the state of the button. True if the toggle button is selected, false if it's not.

setSelected

public void setSelected(boolean b)
Sets the state of the button. Note that this method does not trigger an actionEvent. Call doClick() to perform a programatic action change.

doClick

public void doClick()
Programatically perform a "click". This does the same thing as if the user had pressed and released the button.

doClick

public void doClick(int pressTime)
Programatically perform a "click". This does the same thing as if the user had pressed and released the button. The button stays visually "pressed" for pressTime milliseconds.

setMargin

public void setMargin(Insets m)
Sets space for margin between the button's border and the label. Setting to null will cause the button to use the default margin. The button's default Border object will use this value to create the proper margin. However, if a non-default border is set on the button, it is that Border object's responsibility to create the appropriate margin space (else this property will effectively be ignored).
Parameters:
m - the space between the border and the label
