Method Detail

createUI

public static ComponentUI createUI(JComponent b)

Description copied from class: ComponentUI

Returns an instance of the UI delegate for the specified component. Each subclass must provide its own static createUI method that returns an instance of that UI delegate subclass. If the UI delegate subclass is stateless, it may return an instance that is shared by multiple components. If the UI delegate is stateful, then it should return a new instance per component. The default implementation of this method throws an error, as it should never be invoked.

---

getPropertyPrefix

protected String getPropertyPrefix()

Overrides:

getPropertyPrefix in class BasicButtonUI

---

paint

public void paint(Graphics g,
                  JComponent c)

Description copied from class: ComponentUI

Paints the specified component appropriate for the look and feel. This method is invoked from the ComponentUI.update method when the specified component is being painted. Subclasses should override this method and use the specified Graphics object to render the content of the component.

Overrides:

paint in class BasicButtonUI

Parameters:

g - the Graphics context in which to paint

c - the component being painted; this argument is often ignored, but might be used if the UI object is stateless and shared by multiple components

See Also:

ComponentUI.update(java.awt.Graphics, javax.swing.JComponent)

paintIcon

protected void paintIcon(Graphics g,
                         AbstractButton b,
                         Rectangle iconRect)

---

getTextShiftOffset

protected int getTextShiftOffset()

Overriden so that the text will not be rendered as shifted for Toggle buttons and subclasses.

Overrides:

getTextShiftOffset in class BasicButtonUI
