Class BasicTableHeaderUI

protected JTableHeader header

The table header that is using this interface.

protected MouseInputListener mouseInputListener

The mouse input listener, responsible for mouse manipulations with the table header.

protected CellRendererPane rendererPane

Paint the header cell.

public BasicTableHeaderUI()

Construct a new BasicTableHeaderUI, create mouse listeners.

protected MouseInputListener createMouseInputListener()

Create and return the mouse input listener.

Returns:

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

public static ComponentUI createUI(JComponent h)

Creates a delegate object for the specified component. Users should use the createUI method of a suitable subclass. The implementation of ComponentUI always throws an error.

Overrides:

createUI in interface ComponentUI

Parameters:

public Dimension getPreferredSize(JComponent ignored)

Get the preferred header size.

Overrides:

getPreferredSize in interface ComponentUI

Parameters:

ignored - unused

Returns:

the preferred size of the associated header.

protected void installDefaults()

protected void installKeyboardActions()

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.

public void installUI(JComponent c)

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 interface ComponentUI

Parameters:

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

ComponentUI.uninstallUI(JComponent), JComponent.setUI(ComponentUI), JComponent.updateUI()

public void paint(Graphics gfx,
                  JComponent c)

Repaint the table header.

Overrides:

paint in interface ComponentUI

protected void uninstallDefaults()

protected void uninstallKeyboardActions()

protected void uninstallListeners()

Remove the previously installed listeners.

public void uninstallUI(JComponent c)

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

Overrides:

uninstallUI in interface ComponentUI

Parameters:

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