How to bring an image to the foreground in Java? -

-

i'm trying create pacman game in java, , far i've displayed background image (the blue , black maze), i'm having trouble showing image of pacman. when try display him in same method displayed background, doesn't appear unless manually alter size of jframe. , when appears there's small white square in bottom right corner of image. can fix this? there other way can insert pacman image in works?

this code:

  jframe window = new jframe();    imageimplement pacman = new imageimplement(new imageicon("c:\\users\\16ayoubc\\desktop\\pacman-moving.gif").getimage());     imageimplement panel = new imageimplement(new imageicon("c:\\users\\16ayoubc\\desktop\\background.png").getimage());    pacman.setlocation(255, 255);   pacman.setvisible(true);   pacman.setopaque(true);   window.add(pacman);   window.add(panel);    window.setvisible(true);   window.setsize(576,655);   window.setname("pacman");   window.setdefaultcloseoperation(jframe.exit_on_close);

use jlayeredpane insted of window directly container , specify depth (z-order) of components when add them.

i used pyinstaller create standalone exe file pyqt project. did not use single file option because exe created single file option takes long open. therefore, pyinstaller created dist folder contains bunch of files including program.exe file. create setup.exe file place contents of dist folder in program directory , create shortcut in start menu , on desktop. want super simple user. maybe setup.exe files when download program cnet. found inno-setup, looks promising. however, not know if there special considerations because program standalone program create python/pyqt program. thanks! have experience task? there program using task not know about? inno-setup or nsis easiest use. tell them files include , put them , create nice installer you. wrote short tutorial on experiences using innosetup might find helpful: http://www.blog.pythonlibrary.org/2008/08/27/packaging-wxpymail-for-distribution/ note tutorial based around wxpython app wrote, concepts same.
