Field Detail

contListener

protected ContainerListener contListener

This protected field is implemenation specific. Do not access directly or override. Use the create method instead.

See Also:

createContainerListener()

---

rolloverListener

protected PropertyChangeListener rolloverListener

This protected field is implemenation specific. Do not access directly or override. Use the create method instead.

See Also:

createRolloverListener()

Constructor Detail

MetalToolBarUI

public MetalToolBarUI()

Method Detail

createUI

public static ComponentUI createUI(JComponent c)

Description copied from class: ComponentUI

Returns an instance of the UI delegate for the specified component. Each subclass must provide its own static createUI method that returns an instance of that UI delegate subclass. If the UI delegate subclass is stateless, it may return an instance that is shared by multiple components. If the UI delegate is stateful, then it should return a new instance per component. The default implementation of this method throws an error, as it should never be invoked.

---

installUI

public void installUI(JComponent c)

Description copied from class: ComponentUI

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 in class BasicToolBarUI

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:

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 in class BasicToolBarUI

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()

---

installListeners

protected void installListeners()

Overrides:

installListeners in class BasicToolBarUI

---

uninstallListeners

protected void uninstallListeners()

Overrides:

uninstallListeners in class BasicToolBarUI

---

createRolloverBorder

protected Border createRolloverBorder()

Description copied from class: BasicToolBarUI

Creates a rollover border for toolbar components. The rollover border will be installed if rollover borders are enabled.

Override this method to provide an alternate rollover border.

Overrides:

createRolloverBorder in class BasicToolBarUI

---

createNonRolloverBorder

protected Border createNonRolloverBorder()

Description copied from class: BasicToolBarUI

Creates the non rollover border for toolbar components. This border will be installed as the border for components added to the toolbar if rollover borders are not enabled.

Override this method to provide an alternate rollover border.

Overrides:

createNonRolloverBorder in class BasicToolBarUI

---

setBorderToNonRollover

protected void setBorderToNonRollover(Component c)

Description copied from class: BasicToolBarUI

Sets the border of the component to have a non-rollover border which was created by createNonRolloverBorder.

Overrides:

setBorderToNonRollover in class BasicToolBarUI

Parameters:

c - component which will have a non-rollover border installed

See Also:

BasicToolBarUI.createNonRolloverBorder()

---

createContainerListener

protected ContainerListener createContainerListener()

Creates a container listener that will be added to the JToolBar. If this method returns null then it will not be added to the toolbar.

Returns:

an instance of a ContainerListener or null

---

createRolloverListener

protected PropertyChangeListener createRolloverListener()

Creates a property change listener that will be added to the JToolBar. If this method returns null then it will not be added to the toolbar.

Returns:

an instance of a PropertyChangeListener or null

---

createDockingListener

protected MouseInputListener createDockingListener()

Overrides:

createDockingListener in class BasicToolBarUI

---

setDragOffset

protected void setDragOffset(Point p)

---
