Re: [ jEdit-users ] Pinning jEdit Properly to Windows 7 taskbar

[John S. <leg...@gm...>]

An update on my progress.  I started by trying to set the AppID of jEdit,
and finally got it to set without freezing during startup :)  Unfortunately,
this wasn't enough, as it appears I also need Launch4j to set the resulting
executable's AppID to be the same thing.

At this point I discovered a different program called WinRun4J (Vampire -
you commented on that issue in Launch4J) which does work!! There isn't a
nice config GUI for it like Launch4J, but the resulting executable it
creates can be properly pinned.  I think the difference is that WinRun4J
doesn't launch javaw.exe in a separate process - perhaps it runs javaw.exe
inside the same process?

One final snag is that I can't seem to properly set the icon - I can only
change the icon which appears in the taskbar, but the icon of the executable
in Windows Explorer remains unchanged, as well as the icon in the
context-menu when you right-click on the taskbar.  I'm looking into the
code, and trying to contact the author.
