BasicInternalFrameTitlePane.SystemMenuBar
public BasicInternalFrameTitlePane.SystemMenuBar()
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
- Overrides:
requestFocus
in class JComponent
- See Also:
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
- See Also:
JComponent.setOpaque(boolean)
