@JavaBean(defaultProperty="UI") public class JSplitPane extends JComponent implements Accessible
JSplitPane
is used to divide two (and only two)
Component
s. The two Component
s
are graphically divided based on the look and feel
implementation, and the two Component
s can then be
interactively resized by the user.
Information on using JSplitPane
is in
How to Use Split Panes in
The Java Tutorial.
The two Component
s in a split pane can be aligned
left to right using
JSplitPane.HORIZONTAL_SPLIT
, or top to bottom using
JSplitPane.VERTICAL_SPLIT
.
The preferred way to change the size of the Component
s
is to invoke
setDividerLocation
where location
is either
the new x or y position, depending on the orientation of the
JSplitPane
.
To resize the Component
s to their preferred sizes invoke
resetToPreferredSizes
.
When the user is resizing the Component
s the minimum
size of the Components
is used to determine the
maximum/minimum position the Component
s
can be set to. If the minimum size of the two
components is greater than the size of the split pane the divider
will not allow you to resize it. To alter the minimum size of a
JComponent
, see JComponent.setMinimumSize(java.awt.Dimension)
.
When the user resizes the split pane the new space is distributed between
the two components based on the resizeWeight
property.
A value of 0,
the default, indicates the right/bottom component gets all the space,
where as a value of 1 indicates the left/top component gets all the space.
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.
