Package Summary Overview Summary

### class:CellRendererPane [NONE]
- All Implemented Interfaces: ImageObserver, MenuContainer, Serializable, Accessible
      public class CellRendererPane
      extends Container
      implements Accessible
  This class is inserted in between cell renderers and the components that use them. It just exists to thwart the repaint() and invalidate() methods which would otherwise propagate up the tree when the renderer was configured. It's used by the implementations of JTable, JTree, and JList. For example, here's how CellRendererPane is used in the code the paints each row in a JList:
         cellRendererPane = new CellRendererPane();
         ...
         Component rendererComponent = renderer.getListCellRendererComponent();
         renderer.configureListCellRenderer(dataModel.getElementAt(row), row);
         cellRendererPane.paintComponent(g, rendererComponent, this, x, y, w, h);
A renderer component must override isShowing() and unconditionally return true to work correctly because the Swing paint does nothing for components with isShowing false. Warning: Serialized objects of this class will not be compatible with future Swing releases. The current serialization support is appropriate for short term storage or RMI between applications running the same version of Swing. As of 1.4, support for long term storage of all JavaBeans™ has been added to the `java.beans` package. Please see `XMLEncoder`. Since: 1.2

### field:accessibleContext [NONE]
- #### accessibleContext
      protected AccessibleContext accessibleContext
`AccessibleContext` associated with this `CellRendererPan`

### constructor:CellRendererPane() [NONE]
- #### CellRendererPane
      public CellRendererPane()
Construct a CellRendererPane object.

### method:invalidate() [NONE]
- #### invalidate
      public void invalidate()
Overridden to avoid propagating a invalidate up the tree when the cell renderer child is configured. Overrides: `invalidate` in class `Container` See Also: `Container.validate()`, `Container.layout()`, `LayoutManager2`

### method:paint(java.awt.Graphics) [NONE]
- #### paint
      public void paint(Graphics g)
Shouldn't be called. Overrides: `paint` in class `Container` Parameters: `g` - the specified Graphics window See Also: `Component.update(Graphics)`

### method:update(java.awt.Graphics) [NONE]
- #### update
      public void update(Graphics g)
Shouldn't be called. Overrides: `update` in class `Container` Parameters: `g` - the specified Graphics window See Also: `Component.update(Graphics)`

### method:addImpl(java.awt.Component, java.lang.Object, int) [NONE]
- #### addImpl
      protected void addImpl(Component x,
                             Object constraints,
                             int index)
If the specified component is already a child of this then we don't bother doing anything - stacking order doesn't matter for cell renderer components (CellRendererPane doesn't paint anyway). Overrides: `addImpl` in class `Container` Parameters: `x` - the component to be added `constraints` - an object expressing layout constraints for this component `index` - the position in the container's list at which to insert the component, where `-1` means append to the end See Also: `Container.add(Component)`, `Container.add(Component, int)` , `Container.add(Component, java.lang.Object)` , `Container.invalidate()`, `LayoutManager`, `LayoutManager2`

### method:paintComponent(java.awt.Graphics, java.awt.Component, java.awt.Container, int, int, int, int, boolean) [NONE]
- #### paintComponent
      public void paintComponent(Graphics g,
                                 Component c,
                                 Container p,
                                 int x,
                                 int y,
                                 int w,
                                 int h,
                                 boolean shouldValidate)
Paint a cell renderer component c on graphics object g. Before the component is drawn it's reparented to this (if that's necessary), it's bounds are set to w,h and the graphics object is (effectively) translated to x,y. If it's a JComponent, double buffering is temporarily turned off. After the component is painted it's bounds are reset to -w, -h, 0, 0 so that, if it's the last renderer component painted, it will not start consuming input. The Container p is the component we're actually drawing on, typically it's equal to this.getParent(). If shouldValidate is true the component c will be validated before painted. Parameters: `g` - the `Graphics` object to draw on `c` - the `Component` to draw `p` - the `Container` component actually drawn on `x` - an int specifying the left side of the area draw in, in pixels, measured from the left edge of the graphics context `y` - an int specifying the top of the area to draw in, in pixels measured down from the top edge of the graphics context `w` - an int specifying the width of the area draw in, in pixels `h` - an int specifying the height of the area draw in, in pixels `shouldValidate` - if true, component `c` will be validated before being painted

### method:paintComponent(java.awt.Graphics, java.awt.Component, java.awt.Container, int, int, int, int) [NONE]

      public void paintComponent(Graphics g,
                                 Component c,

                                 int x,
                                 int y,
                                 int w,
                                 int h)
Calls this.paintComponent(g, c, p, x, y, w, h, false). Parameters: `g` - the `Graphics` object to draw on `c` - the `Component` to draw `p` - the `Container` component actually drawn on `x` - an int specifying the left side of the area draw in, in pixels, measured from the left edge of the graphics context `y` - an int specifying the top of the area to draw in, in pixels measured down from the top edge of the graphics context `w` - an int specifying the width of the area draw in, in pixels `h` - an int specifying the height of the area draw in, in pixels

      public void paintComponent(Graphics g,

                                 Rectangle r)
Calls this.paintComponent() with the rectangles x,y,width,height fields. Parameters: `g` - the `Graphics` object to draw on `c` - the `Component` to draw `p` - the `Container` component actually drawn on `r` - the `Rectangle` to draw in

### method:getAccessibleContext() [NONE]
- #### getAccessibleContext
      public AccessibleContext getAccessibleContext()
