Java Swing - O Reilly As with all of the other Swing components, this method updates the look-and-feel for the tooltip based on the UIManager. 27.2 Editing and Rendering Utilities Both the JTree and JTable classes make use of cell renderers to display cells and cell editors to modify cell values. The CellEditor interface is the basis for these editors, and the DefaultCellEditor class provides a good implementation of this interface. Unless you’re doing something exotic, you should be able to base your cell editors on the DefaultCellEditor class. 27.2.1 The CellRendererPane Class This utility class was built to keep renderers from propagating repaint() and validate() calls to the components using renderer components such as JTree and JList. If you played around with creating your own renderers for any of the Swing components that use them, you’ll recall that you did not use this class yourself. Normally this pane is wrapped around the renderer and the paintComponent() methods below are used to do the actual drawing. Developers will not normally need to worry about this class. 27.2.1.1 Property The CellRendererPane has only one property containing its accessible context, shown in Table 27.5. Table 27.5, CellRendererPane Property Property Data Type get is set bound Default Value accessibleContext AccessibleContext CellRendererPane.AccessibleCellRendererPane 27.2.1.2 Field protected AccessibleContext accessibleContext This field supports the accessibleContext property. 27.2.1.3 Constructor This class has only one constructor. public CellRendererPane() This constructor creates a new renderer pane that has a null layout and is not initially visible. 27.2.1.4 Methods protected void addImpl(Component x, Object constraints, int index) public void invalidate() public void paint(Graphics g) public void update(Graphics g) - 923
