New Revision: 1623
Added:
izpack-src/branches/branch-rsshilli/src/lib/com/izforge/izpack/gui/JPanelWithBackground.java

Log:
- Added a new attribute to the "uninstaller" element called "path". It's the path that the uninstaller jar will be deployed to on install.
- We now differentiate between when closing requires asking and when closing requires the files to be removed. This way it still asks you if you want to quite at any time before the finish panel.
- Added an optional splash screen that shows up with the installer starts up.
- Add a resource called "SplashScreen" and it will be compiled in and come up. ie:
<res id="SplashScreen" src="installer/resources/InstallerSplash.png"/>
- Also, on Solaris over some old XWindows clients had a hard time showing the splash screen, so if you start the installer with -Dskip_splash=true then the splash screen doesn't get shown.
- If you specify a resource named "Icon", the installer will use that instead of the default IzPack icon.
- Shutdown file cleanup now uses the Housekeeper. Hence, if you add additional shutdown hooks to the Housekeeper they will get executed before the files are removed.
