Class DecoratorPanel
public class DecoratorPanel extends SimplePanel
A SimplePanel that wraps its contents in stylized boxes, which can be
used to add rounded corners to a Widget.
This widget will only work in quirks mode in most cases. Specifically, setting the height or width of the DecoratorPanel will result in rendering issues.
Wrapping a Widget in a "9-box" allows users to specify images in each
of the corners and along the four borders. This method allows the content
within the DecoratorPanel to resize without disrupting the look of
the border. In addition, rounded corners can generally be combined into a
single image file, which reduces the number of downloaded files at startup.
This class also simplifies the process of using AlphaImageLoaders to support
8-bit transparencies (anti-aliasing and shadows) in ie6, which does not
support them normally.
If you set the width or height of the DecoratorPanel, you need to
set the height and width of the middleCenter cell to 100% so that the
middleCenter cell takes up all of the available space. If you do not set the
width and height of the DecoratorPanel, it will wrap its contents
tightly.
