public BasicTableHeaderUI()

createMouseInputListener

createUI

public static ComponentUI createUI(JComponent h)

installUI

public void installUI(JComponent c)

Description copied from class: [ComponentUI](../../../../javax/swing/plaf/ComponentUI.html#installUI%28javax.swing.JComponent%29)

Configures the specified component appropriate 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:

1. Install any 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.
2. Install a LayoutManager on the component if necessary.
3. Create/add any required sub-components to the component.
4. Create/install event listeners on the component.
5. Create/install a PropertyChangeListener on the component in order to detect and respond to component property changes appropriately.
6. Install keyboard UI (mnemonics, traversal, etc.) on the component.
7. Initialize any appropriate instance data.

Overrides:

[installUI](../../../../javax/swing/plaf/ComponentUI.html#installUI%28javax.swing.JComponent%29) in class [ComponentUI](../../../../javax/swing/plaf/ComponentUI.html "class in javax.swing.plaf")

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()

installDefaults

protected void installDefaults()

Initialize JTableHeader properties, e.g. font, foreground, and background. The font, foreground, and background properties are only set if their current value is either null or a UIResource, other properties are set if the current value is null.

See Also:

installUI(javax.swing.JComponent)

installListeners

protected void installListeners()

Attaches listeners to the JTableHeader.

installKeyboardActions

protected void installKeyboardActions()

Register all keyboard actions on the JTableHeader.

uninstallUI

public void uninstallUI(JComponent c)

Description copied from class: [ComponentUI](../../../../javax/swing/plaf/ComponentUI.html#uninstallUI%28javax.swing.JComponent%29)

Reverses configuration which was done on the specified component duringinstallUI. 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:

1. Remove any UI-set borders from the component.
2. Remove any UI-set layout managers on the component.
3. Remove any UI-added sub-components from the component.
4. Remove any UI-added event/property listeners from the component.
5. Remove any UI-installed keyboard UI from the component.
6. Nullify any allocated instance data objects to allow for GC.

Overrides:

[uninstallUI](../../../../javax/swing/plaf/ComponentUI.html#uninstallUI%28javax.swing.JComponent%29) in class [ComponentUI](../../../../javax/swing/plaf/ComponentUI.html "class in javax.swing.plaf")

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()

uninstallDefaults

protected void uninstallDefaults()

uninstallListeners

protected void uninstallListeners()

uninstallKeyboardActions

protected void uninstallKeyboardActions()

paint

public void paint(Graphics g, JComponent c)

Description copied from class: [ComponentUI](../../../../javax/swing/plaf/ComponentUI.html#paint%28java.awt.Graphics, javax.swing.JComponent%29)

Paints the specified component appropriate 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](../../../../javax/swing/plaf/ComponentUI.html#paint%28java.awt.Graphics, javax.swing.JComponent%29) in class [ComponentUI](../../../../javax/swing/plaf/ComponentUI.html "class in javax.swing.plaf")

Parameters:

g - the Graphics 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

[ComponentUI.update(java.awt.Graphics, javax.swing.JComponent)](../../../../javax/swing/plaf/ComponentUI.html#update%28java.awt.Graphics, javax.swing.JComponent%29)

getMinimumSize

public Dimension getMinimumSize(JComponent c)

Return the minimum size of the header. The minimum width is the sum of the minimum widths of each column (plus inter-cell spacing).

Overrides:

[getMinimumSize](../../../../javax/swing/plaf/ComponentUI.html#getMinimumSize%28javax.swing.JComponent%29) in class [ComponentUI](../../../../javax/swing/plaf/ComponentUI.html "class in javax.swing.plaf")

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 or null

See Also:

JComponent.getMinimumSize(), LayoutManager.minimumLayoutSize(java.awt.Container), ComponentUI.getPreferredSize(javax.swing.JComponent)

getPreferredSize

public Dimension getPreferredSize(JComponent c)

Return the preferred size of the header. The preferred height is the maximum of the preferred heights of all of the components provided by the header renderers. The preferred width is the sum of the preferred widths of each column (plus inter-cell spacing).

Overrides:

[getPreferredSize](../../../../javax/swing/plaf/ComponentUI.html#getPreferredSize%28javax.swing.JComponent%29) in class [ComponentUI](../../../../javax/swing/plaf/ComponentUI.html "class in javax.swing.plaf")

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)

getMaximumSize

public Dimension getMaximumSize(JComponent c)

Return the maximum size of the header. The maximum width is the sum of the maximum widths of each column (plus inter-cell spacing).

Overrides:

[getMaximumSize](../../../../javax/swing/plaf/ComponentUI.html#getMaximumSize%28javax.swing.JComponent%29) in class [ComponentUI](../../../../javax/swing/plaf/ComponentUI.html "class in javax.swing.plaf")

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 or null
