installUI

public void installUI(JComponent c)

uninstallUI

public void uninstallUI(JComponent c)

paint

public void paint(Graphics g,
                  JComponent c)

update

public void update(Graphics g,
                   JComponent c)

getPreferredSize

public Dimension getPreferredSize(JComponent c)

getMinimumSize

public Dimension getMinimumSize(JComponent c)

getMaximumSize

public Dimension getMaximumSize(JComponent c)

contains

public boolean contains(JComponent c,
                        int x,
                        int y)

createUI

public static ComponentUI createUI(JComponent c)

getAccessibleChildrenCount

public int getAccessibleChildrenCount(JComponent c)
Returns the number of accessible children in the object. If all of the children of this object implement Accessible, than this method should return the number of children of this object. UI's might wish to override this if they present areas on the screen that can be viewed as components, but actual components are not used for presenting those areas. Note: as of the Java 2 platform v1.3, it is recommended that developers call Component.AccessibleAWTComponent.getAccessibleChildrenCount() instead of using this method.
Returns:
the number of accessible children in the object.

getAccessibleChild(javax.swing.JComponent, int)

getAccessibleChild

public Accessible getAccessibleChild(JComponent c,
                                     int i)
Return the nth Accessible child of the object. UI's might wish to override this if they present areas on the screen that can be viewed as components, but actual components are not used for presenting those areas. Note: as of the Java 2 platform v1.3, it is recommended that developers call Component.AccessibleAWTComponent.getAccessibleChild() instead of using this method.
Parameters:
i - zero-based index of child
Returns:
the nth Accessible child of the object
