void	draw() Draw the button.
int	getHeight()
Dimension	getSize() Return the size of the button.
int	getWidth()
Dimension	minimumSize() Called by the LayoutManager.
void	processKeyEvent(KeyEvent ke_) Processes key events occurring on this object by dispatching them to any registered KeyListener objects.
void	requestFocus() This method should be invoked by all subclasses of Component which override this method; because this method generates the FOCUS_GAINED event when the component gains the keyboard focus.
void	setLabel(java.lang.String label_) Deprecated. Replaced by setText(String text)
void	setText(java.lang.String label_) Sets the button's label text.
