b- an abstract button- Returns:
- the default gap between text and an icon
-
paintIcon
protected void paintIcon(Graphics g, JComponent c, Rectangle iconRect)
Paints an icon of the current button.- Parameters:
g- an instance ofGraphicsc- a componenticonRect- a bounding rectangle to render the icon
-
paintText
protected void paintText(Graphics g, JComponent c, Rectangle textRect, String text)
Method which renders the text of the current button. As of Java 2 platform v 1.4 this method should not be used or overriden. Use the paintText method which takes the AbstractButton argument.- Parameters:
