Constructors
BasicDesktopPaneUI
public BasicDesktopPaneUI()
Methods
createUI
public static ComponentUI createUI(JComponent c)
installUI
public void installUI(JComponent c)
Description copied from class: ComponentUI
Configures the specified component appropriately for the look and feel. This method is invoked when the ComponentUI
instance is being installed as the UI delegate on the specified component. This method should completely configure the component for the look and feel, including the following:
- Install default property values for color, fonts, borders, icons, opacity, etc. on the component. Whenever possible, property values initialized by the client program should not be overridden.
- Install a
LayoutManager
on the component if necessary. - Create/add any required sub-components to the component.
- Create/install event listeners on the component.
- Create/install a
PropertyChangeListener
on the component in order to detect and respond to component property changes appropriately. - Install keyboard UI (mnemonics, traversal, etc.) on the component.
- Initialize any appropriate instance data.
- Overrides:
-
installUI
in classComponentUI
- Parameters:
-
c
- the component where this UI delegate is being installed - See Also:
-
ComponentUI.uninstallUI(javax.swing.JComponent)
,JComponent.setUI(javax.swing.plaf.ComponentUI)
,JComponent.updateUI()
uninstallUI
public void uninstallUI(JComponent c)
Description copied from class: ComponentUI
Reverses configuration which was done on the specified component during installUI
. This method is invoked when this UIComponent
instance is being removed as the UI delegate for the specified component. This method should undo the configuration performed in installUI
, being careful to leave the JComponent
instance in a clean state (no extraneous listeners, look-and-feel-specific property objects, etc.). This should include the following:
- Remove any UI-set borders from the component.
- Remove any UI-set layout managers on the component.
- Remove any UI-added sub-components from the component.
- Remove any UI-added event/property listeners from the component.
- Remove any UI-installed keyboard UI from the component.
- Nullify any allocated instance data objects to allow for GC.
- Overrides:
-
uninstallUI
in classComponentUI
- Parameters:
-
c
- the component from which this UI delegate is being removed; this argument is often ignored, but might be used if the UI object is stateless and shared by multiple components - See Also:
-
ComponentUI.installUI(javax.swing.JComponent)
,JComponent.updateUI()

paint
public void paint(Graphics g, JComponent c)
Description copied from class: ComponentUI
Paints the specified component appropriately for the look and feel. This method is invoked from the ComponentUI.update
method when the specified component is being painted. Subclasses should override this method and use the specified Graphics
object to render the content of the component.
- Overrides:
-
paint
in classComponentUI
- Parameters:
-
g
- theGraphics
context in which to paint -
c
- the component being painted; this argument is often ignored, but might be used if the UI object is stateless and shared by multiple components - See Also:
ComponentUI.update(java.awt.Graphics, javax.swing.JComponent)
getPreferredSize
public Dimension getPreferredSize(JComponent c)
Description copied from class: ComponentUI
Returns the specified component's preferred size appropriate for the look and feel. If null
is returned, the preferred size will be calculated by the component's layout manager instead (this is the preferred approach for any component with a specific layout manager installed). The default implementation of this method returns null
.
- Overrides:
-
getPreferredSize
in classComponentUI
- Parameters:
-
c
- the component whose preferred size is being queried; this argument is often ignored, but might be used if the UI object is stateless and shared by multiple components - See Also:
-
JComponent.getPreferredSize()
,LayoutManager.preferredLayoutSize(java.awt.Container)
getMinimumSize
public Dimension getMinimumSize(JComponent c)
Description copied from class: ComponentUI
Returns the specified component's minimum size appropriate for the look and feel. If null
is returned, the minimum size will be calculated by the component's layout manager instead (this is the preferred approach for any component with a specific layout manager installed). The default implementation of this method invokes getPreferredSize
and returns that value.
- Overrides:
-
getMinimumSize
in classComponentUI
- Parameters:
-
c
- the component whose minimum size is being queried; this argument is often ignored, but might be used if the UI object is stateless and shared by multiple components - Returns:
- a
Dimension
object ornull
- See Also:
-
JComponent.getMinimumSize()
,LayoutManager.minimumLayoutSize(java.awt.Container)
,ComponentUI.getPreferredSize(javax.swing.JComponent)
getMaximumSize
public Dimension getMaximumSize(JComponent c)
Description copied from class: ComponentUI
Returns the specified component's maximum size appropriate for the look and feel. If null
is returned, the maximum size will be calculated by the component's layout manager instead (this is the preferred approach for any component with a specific layout manager installed). The default implementation of this method invokes getPreferredSize
and returns that value.
- Overrides:
-
getMaximumSize
in classComponentUI
- Parameters:
-
c
- the component whose maximum size is being queried; this argument is often ignored, but might be used if the UI object is stateless and shared by multiple components - Returns:
- a
Dimension
object ornull
- See Also:
-
JComponent.getMaximumSize()
,LayoutManager2.maximumLayoutSize(java.awt.Container)
createPropertyChangeListener
protected PropertyChangeListener createPropertyChangeListener()
Returns the PropertyChangeListener
to install on the JDesktopPane
.
- Returns:
- The PropertyChangeListener that will be added to track changes in the desktop pane.
- Since:
- 1.5
