public void requestFocus()
Component
This method cannot be used to set the focus owner to no Component at
all. Use KeyboardFocusManager.clearGlobalFocusOwner()
instead.
Because the focus behavior of this method is platform-dependent,
developers are strongly encouraged to use
requestFocusInWindow
when possible.
requestFocus
in class JComponent
public void paint(Graphics g)
JComponent
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
.

public boolean isOpaque()
JComponent
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.
