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

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

Thanks.  After looking at Launch4j, I don't think the fix is there.  Reading
around, it seems like jEdit might not be setting its Application User Model
ID (AppUserModelID).  So what is happening is that I have jedit.exe pinned
to the taskbar, but when I launch it Windows 7 thinks the actual program is
javaw.exe.

I referred to the following links for my information:

http://stackoverflow.com/questions/1907735/using-jna-to-get-set-application-identifier

Is it acceptable for me to modify jEdit to explicitly sets it's Model ID on
windows 7?  This would of course be OS-specific.
