  public BasicDesktopIconUI()

Method Detail

• 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:

  1. 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.
  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 ComponentUI

  Parameters:

  c - the component where this UI delegate is being installed

  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 ComponentUI

  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

• 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 class ComponentUI

  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 class ComponentUI

  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)

• getMaximumSize

  public Dimension getMaximumSize(JComponent c)

  Desktop icons can not be resized. Therefore, we should always return the minimum size of the desktop icon.

  Overrides:

  getMaximumSize in class ComponentUI

  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

  public Insets getInsets(JComponent c)

• deiconize

  public void deiconize()
