@JavaBean(defaultProperty="UI", description="A component which displays commonly used controls or Actions.") public class JToolBar extends JComponent implements SwingConstants, Accessible
JToolBar
provides a component that is useful for displaying commonly used Action
s or controls. For examples and information on using tool bars see How to Use Tool Bars, a section in The Java Tutorial.
With most look and feels, the user can drag out a tool bar into a separate window (unless the floatable
property is set to false
). 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".
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

property, which is true
if the border should be painted. The default value for this property is true

Paints the tool bar's border if the borderPainted
property is true

@BeanProperty(preferred=true, description="Can the tool bar be made to float by the user?") public void setFloatable(boolean b)
Sets the floatable
property, which must be true
for the user to move the tool bar. Typically, a floatable tool bar can be dragged into a different position within the same container or out into its own window. The default value of this property is true
. Some look and feels might not implement floatable tool bars; they will ignore this property.
- Parameters:
-
b
- iftrue
, the tool bar can be moved;false
otherwise - See Also:
isFloatable()
getOrientation
public int getOrientation()

is an invalid value, an exception will be thrown.
- Parameters:
-
o
- the new orientation -- eitherHORIZONTAL
orVERTICAL
- Throws:
-

norVERTICAL
- See Also:
getOrientation()
setRollover
@BeanProperty(preferred=true, visualUpdate=true, description="Will draw rollover button borders in the toolbar.") public void setRollover(boolean rollover)
Sets the rollover state of this toolbar. If the rollover state is true then the border of the toolbar buttons will be drawn only when the mouse pointer hovers over them. The default value of this property is false.
