ok, i have a problem with JLayeredPane. I'm about to make a game in full screen mode, so basically I create a JFrame first, and I named it MainMenu.java. In this JFrame, I first display my main menu, where there are 4 main buttons there. When the button is click, the mainmenu is supposed to disappear and replaced with the related menu. To make it work, I create a JLayeredPane named Panel that contains everything for the mainmenu. To open the menu, I simply nullify the Panel and add new JLayeredPane to fills the Panel. To make it easy, I separate the submenu class into SubMenu.java. My problem is, when I first run the program, there's nothing in the frame (there's supposed to be a JLayeredPane named Panel that contains the mainmenu). Then I minimize the window, and maximize it again. Boom, I got the main menu I want. Then I try to open the menu in it, and everything freezes. I minimize and maximize the window again, and I got the menu I want. Can someone here please tell me what's wrong? It seems like the Panel can't refresh whenever I change it.
Here's the code for MainMenu.java and SubMenu.java. You can ignore most part of the code, since it's still basic for the button animation. But please pay attention with the Panel.
