public class JSeparator

extends JComponent

implements SwingConstants, Accessible

An implementation of a Menu Separator -- a divider between menu items that breaks them up into logical groupings.

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.

JSeparator

public JSeparator()

Create a new horizontal separator.

JSeparator

public JSeparator(int orientation)

Create a new separator with the specified horizontal or vertical orientation.

Parameters:

orientation - an int specifying SwingConstants.HORIZONTAL or SwingConstants.VERTICAL

Method Detail

getUI

public SeparatorUI getUI()

/** Returns the L&F object that renders this component.

Returns:

the SeparatorUI object that renders this component

setUI

public void setUI(SeparatorUI ui)

Sets the L&F object that renders this component.

Parameters:

ui - the SeparatorUI L&F object

See Also:

UIDefaults.getUI(javax.swing.JComponent)

updateUI

public void updateUI()

Notification from the UIFactory that the L&F has changed. Called to replace the UI with the latest version from the UIFactory.

Overrides:

updateUI in class JComponent

See Also:

JComponent.updateUI()

getUIClassID

public String getUIClassID()

Returns the name of the L&F class that renders this component.

Returns:

"SeparatorUI"

Overrides:

getUIClassID in class JComponent

See Also:

JComponent.getUIClassID(), UIDefaults.getUI(javax.swing.JComponent)

getOrientation

public int getOrientation()

Returns the orientation of this separator.

Returns:

The value of the orientation property, one of the following constants defined in SwingConstants: VERTICAL, or HORIZONTAL.

See Also:
