public class JToolBar

extends JComponent

implements SwingConstants, Accessible

JToolBar provides a component which is useful for displaying commonly used Actions or controls. It can be dragged out into a separate window by the user (unless the floatable property is set to false). In order for drag-out to work correctly, it is recommended that you add JToolBar instances to one of the four 'sides' of a container whose layout manager is a BorderLayout, and do not add children to any of the other four 'sides'.

For the keyboard keys used by this component in the standard Look and Feel (L&F) renditions, see the JToolBar key assignments.

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 Swing1.0 applications. It will not be possible to load serialized Swing1.0 objects with future releases of Swing. The JDK1.2 release of Swing will be the compatibility baseline for the serialized form of Swing objects.

Constructor Detail

JToolBar

public JToolBar()

Create a new toolbar.

JToolBar

public JToolBar(int orientation)

Method Detail

getUI

public ToolBarUI getUI()

Returns the toolbar's current UI.

See Also:

setUI

setUI

public void setUI(ToolBarUI ui)

Sets the L&F object that renders this component.

Parameters:

ui - the ToolBarUI L&F object

See Also:

UIDefaults.getUI(com.sun.java.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:

"ToolBarUI"

Overrides:

getUIClassID in class JComponent

See Also:

JComponent.getUIClassID(), UIDefaults.getUI(com.sun.java.swing.JComponent)

getComponentIndex

public int getComponentIndex(Component c)

getComponentAtIndex

public Component getComponentAtIndex(int i)

setMargin

public void setMargin(Insets m)

Sets the margin between the toolbar's border and its buttons. Setting to null causes the toolbar to use the default margins. The toolbar's default Border object uses this value to create the proper margin. However, if a non-default border is set on the toolbar, it is that Border object's responsibility to create the appropriate margin space (otherwise this property will effectively be ignored).

Parameters:

m - an Insets object that defines the space between the border and the buttons

See Also:

Returns the margin between the toolbar's border and its buttons.

Returns:

an Insets object containing the margin values
