问题 I was wondering if it were possible to layer ImageIcons in Java. I will be working with GIF images, and will have a grid of ImageIcons representing the "background" of my JPane. When a certain condition is true, I need to be able to add an image that has transparency on top of the other image. Regards, Jack Hunt 回答1: yes that's possible and there are two correct ways 1) if is there only one Image then put JLabel with Icon to the GlassPane 2) use LayeredPane for <= Java6 (not Java7 user there
