My aim is to have multiple panels with images that have alpha channels (transparent parts) on top of each other. So I followed the code in this site http://tinyurl.com/m27exs. It worked the way I wanted it. It had two ImagePanel
objects on top of each other with the top-most having an alpha channel (transparent part).
现在我的问题是,我如何能够改变<代码>ImageIcon的物体在<编码>内的透明度(见通过?)?
