  public BasicInternalFrameTitlePane.SystemMenuBar()

Method Detail

• isFocusTraversable

  public boolean isFocusTraversable()

  Description copied from class: Component
  Returns whether this Component can become the focus owner.

  Overrides:

  isFocusTraversable in class Component

  Returns:

  true if this Component is focusable; false otherwise

  See Also:

  Component.setFocusable(boolean)

• requestFocus

  public void requestFocus()

  Description copied from class: JComponent
  Requests that this Component gets the input focus. Refer to Component.requestFocus() for a complete description of this method.

  Note that the use of this method is discouraged because its behavior is platform dependent. Instead we recommend the use of requestFocusInWindow(). If you would like more information on focus, see How to Use the Focus Subsystem, a section in The Java Tutorial.

  Overrides:

  requestFocus in class JComponent

  Component.requestFocusInWindow(), Component.requestFocusInWindow(boolean)

• paint

  public void paint(Graphics g)

  Description copied from class: JComponent
  Invoked by Swing to draw components. Applications should not invoke paint directly, but should instead use the repaint method to schedule the component for redrawing.

  This method actually delegates the work of painting to three protected methods: paintComponent, paintBorder, and paintChildren. They're called in the order listed to ensure that children appear on top of component itself. Generally speaking, the component and its children should not paint in the insets area allocated to the border. Subclasses can just override this method, as always. A subclass that just wants to specialize the UI (look and feel) delegate's paint method should just override paintComponent.

  Overrides:

  paint in class JComponent

  Parameters:

  g - the Graphics context in which to paint

  See Also:

  JComponent.paintComponent(java.awt.Graphics), JComponent.paintBorder(java.awt.Graphics), JComponent.paintChildren(java.awt.Graphics), JComponent.getComponentGraphics(java.awt.Graphics), JComponent.repaint(long, int, int, int, int)

• isOpaque

  public boolean isOpaque()

  Description copied from class: JComponent
  Returns true if this component is completely opaque.

  An opaque component paints every pixel within its rectangular bounds. A non-opaque component paints only a subset of its pixels or none at all, allowing the pixels underneath it to "show through". Therefore, a component that does not fully paint its pixels provides a degree of transparency.

  Subclasses that guarantee to always completely paint their contents should override this method and return true.

  Overrides:

  isOpaque in class JComponent

  Returns:

  true if this component is completely opaque

  JComponent.setOpaque(boolean)
