BasicInternalFrameTitlePane.SystemMenuBar
public BasicInternalFrameTitlePane.SystemMenuBar()
isFocusTraversable
public boolean isFocusTraversable()
- Description copied from class: JComponent
- Identifies whether or not this component can receive the focus.
A disabled button, for example, would return false.
- Overrides:
- isFocusTraversable in class JComponent
- Tags copied from class: JComponent
- Returns:
- true if this component can receive the focus
requestFocus
public void requestFocus()
- Description copied from class: JComponent
- Set focus on the receiving component if isRequestFocusEnabled returns true
- Overrides:
- requestFocus in class JComponent
- Tags copied from class: Component
- See Also:

Component.addFocusListener(java.awt.event.FocusListener)
,
Component.processFocusEvent(java.awt.event.FocusEvent)

paint
public void paint(Graphics g)
- Description copied from class: JComponent
- This method is 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) delegates paint
method should just override paintComponent
.
- Overrides:
- paint in class JComponent
- Tags copied from class: JComponent
- 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 region. A non-opaque component paints only some of
its pixels, allowing the pixels underneath it to "show through".
A component that does not fully paint its pixels therefore
provides a degree of transparency.
Subclasses that guarantee to always completely paint their contents should
override this method and return true.
This method will migrate to java.awt.Component in the next major JDK release
- Overrides:
- isOpaque in class JComponent
- Tags copied from class: JComponent
- Returns:
- true if this component is completely opaque.
- See Also:
JComponent.setOpaque(boolean)
