Constructor Detail

BasicTableHeaderUI

public BasicTableHeaderUI()

Construct a new BasicTableHeaderUI, create mouse listeners.

Method Detail

createUI

public static ComponentUI createUI(JComponent h)

createMouseInputListener

protected MouseInputListener createMouseInputListener()

Create and return the mouse input listener.

Returns:

the mouse listener (BasicTableHeaderUI.MouseInputHandler, if not overridden.

installDefaults

protected void installDefaults()

installKeyboardActions

protected void installKeyboardActions()

installListeners

protected void installListeners()

Add the mouse listener and the mouse motion listener to the table header. The listeners support table column resizing and rearrangement by mouse.

installUI

public void installUI(JComponent c)

Description copied from class: ComponentUI

Sets up the specified component so it conforms the the design guidelines of the implemented look and feel. When the look and feel changes, a ComponentUI delegate is created. The delegate object then receives an installUI message.

This method should perform the following tasks:

• Set visual properties such as borders, fonts, colors, or icons. However, no change should be performed for those properties whose values have been directly set by the client application. To allow the distinction, LookAndFeels are expected to use values that implement the UIResource marker interface, such as BorderUIResource or ColorUIResource.
• If necessary, install a LayoutManager.
• Embed custom sub-components. For instance, the UI delegate for a JSplitPane might install a special component for the divider.
• Register event listeners.
• Set up properties related to keyborad navigation, such as mnemonics or focus traversal policies.

Overrides:

installUI in class ComponentUI

Parameters:

c - the component for which this delegate will provide services.

uninstallDefaults

protected void uninstallDefaults()

uninstallKeyboardActions

protected void uninstallKeyboardActions()

uninstallListeners

protected void uninstallListeners()

Remove the previously installed listeners.

uninstallUI

public void uninstallUI(JComponent c)

Description copied from class: ComponentUI

Puts the specified component into the state it had before ComponentUI.installUI(javax.swing.JComponent) was called.

Overrides:

uninstallUI in class ComponentUI

Parameters:

c - the component for which this delegate has provided services.

See Also:

ComponentUI.installUI(javax.swing.JComponent), JComponent.setUI(javax.swing.plaf.ComponentUI), JComponent.updateUI()

paint

public void paint(Graphics gfx,
         JComponent c)

Repaint the table header.

Overrides:

paint in class ComponentUI

Parameters:

gfx - the graphics for painting.

c - the component for which this delegate performs services.

getPreferredSize

public Dimension getPreferredSize(JComponent ignored)

Get the preferred header size.

Overrides:

getPreferredSize in class ComponentUI

Parameters:

ignored - unused

Returns:

the preferred size of the associated header.
