Returns true if the specified x,y location is contained within the look and feel's defined shape of the specified component.

  Returns true if the specified x,y location is
contained within the look and feel's defined shape of the specified
component. x and y are defined to be relative
to the coordinate system of the specified component. Although
a component's bounds is constrained to a rectangle,
this method provides the means for defining a non-rectangular
shape within those bounds for the purpose of hit detection.
Parameters:
- c - the component where the x,y location is being queried; this argument is often ignored, but might be used if the UI object is stateless and shared by multiple components
- x - the x coordinate of the point
- y - the y coordinate of the point

  Creates an instance of MouseWheelListener, which is added to the JScrollPane by installUI().

  Creates an instance of MouseWheelListener, which is added to the
JScrollPane by installUI(). The returned MouseWheelListener is used
to handle mouse wheel-driven scrolling.
Returns: MouseWheelListener which implements wheel-driven scrolling
Since: 1.4

  Creates an instance of PropertyChangeListener that's added to the JScrollPane by installUI().

  Creates an instance of PropertyChangeListener that's added to
the JScrollPane by installUI(). Subclasses can override this method
to return a custom PropertyChangeListener, e.g.

 class MyScrollPaneUI extends BasicScrollPaneUI {
    protected PropertyChangeListener createPropertyChangeListener() {
        return new MyPropertyChangeListener();
    }
    public class MyPropertyChangeListener extends PropertyChangeListener {
        public void propertyChange(PropertyChangeEvent e) {
            if (e.getPropertyName().equals("viewport")) {
                // do some extra work when the viewport changes
            }
            super.propertyChange(e);
        }
    }
 }

  Returns the ith Accessible child of the object.

  Returns the ith Accessible child of the object. UIs might need 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 v1.3, it is recommended that developers call Component.AccessibleAWTComponent.getAccessibleChild() instead of this method.
Returns: the ith Accessible child of the object
Parameters:
- i - zero-based index of child
See Also: ComponentUI.getAccessibleChildrenCount(javax.swing.JComponent),

  Returns the number of accessible children in the object.

  Returns the number of accessible children in the object. If all
of the children of this object implement Accessible,
this
method should return the number of children of this object.
UIs 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 v1.3, it is recommended that developers call
Component.AccessibleAWTComponent.getAccessibleChildrenCount() instead
of this method.
Returns: the number of accessible children in the object
See Also: ComponentUI.getAccessibleChild(javax.swing.JComponent, int),

  Returns the baseline.

  Returns the baseline.
Throws:
- NullPointerException - {@inheritDoc}
- IllegalArgumentException - {@inheritDoc}
Since: 1.6
See Also: JComponent.getBaseline(int, int),

  Returns an enum indicating how the baseline of the component changes as the size changes.

  Returns an enum indicating how the baseline of the component
changes as the size changes.
Throws:
- NullPointerException - {@inheritDoc}
Since: 1.6
See Also: JComponent.getBaseline(int, int),

 

 
Returns: new Dimension(Short.MAX_VALUE, Short.MAX_VALUE)

  Returns the specified component's minimum size appropriate for the look and feel.

  Returns the specified component's minimum size appropriate for
the look and feel. If null is returned, the minimum
size will be calculated by the component's layout manager instead
(this is the preferred approach for any component with a specific
layout manager installed). The default implementation of this
method invokes getPreferredSize and returns that value.
Returns: a Dimension object or null
Parameters:
- c - the component whose minimum 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.getMinimumSize(), LayoutManager.minimumLayoutSize(java.awt.Container), ComponentUI.getPreferredSize(javax.swing.JComponent),

  Returns the specified component's preferred size appropriate for the look and feel.

  Returns the specified component's preferred size appropriate for
the look and feel. If null is returned, the preferred
size will be calculated by the component's layout manager instead
(this is the preferred approach for any component with a specific
layout manager installed). The default implementation of this
method returns null.
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),

  Notifies this UI delegate that it's time to paint the specified component.

  Notifies this UI delegate that it's time to paint the specified
component. This method is invoked by JComponent
when the specified component is being painted.
By default this method will fill the specified component with
its background color (if its opaque property is
true) and then immediately call paint.
In general this method need not be overridden by subclasses;
all look-and-feel rendering code should reside in the paint
method.
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
