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 BasicToggleButtonUI

installDefaults

protected void installDefaults(AbstractButton b)

Overrides:: installDefaults in class BasicButtonUI

uninstallDefaults

protected void uninstallDefaults(AbstractButton b)

Overrides:: uninstallDefaults in class BasicButtonUI

getDefaultIcon

public Icon getDefaultIcon()

paint

public void paint(Graphics g,
                  JComponent c)

paint the radio button

Overrides:: paint in class BasicToggleButtonUI

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)

paintFocus

protected void paintFocus(Graphics g,
                          Rectangle textRect,
                          Dimension size)

getPreferredSize

public Dimension getPreferredSize(JComponent c)

The preferred size of the radio button

Overrides:: getPreferredSize in class BasicButtonUI

Parameters:: c - the component whose preferred size is being queried; this argument is often ignored, but might be used if the UI object is stateless and shared by multiple components
See Also:: JComponent.getPreferredSize(), LayoutManager.preferredLayoutSize(java.awt.Container)
