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

[Vampire <Va...@jE...>]

Hi John,

jedit.exe is a Launch4J generated executable that forks a new process in 
which it starts javaw.exe.
The C code looks more or less like:

CreateProcess(NULL, cmdline, NULL, NULL, TRUE, priority, NULL, NULL, 
&si, &pi))
WaitForSingleObject(pi.hProcess, INFINITE);
GetExitCodeProcess(pi.hProcess, &dwExitCode);
CloseHandle(pi.hThread);
CloseHandle(pi.hProcess);
return dwExitCode;

Better would be a call via JNI for which also a patch for Launch4J 
exists but it is not accepted and rather outdated now.

But I don't think this has any relevance to your "problem".

If you have chosen "Start jEdit Server automatically on system startup" 
on installation time, then if you startup Windows, jEdit is also started 
but without GUI and is running in the background, ready to quickly show 
the GUI if you need it to. I guess you have chosen this and you can 
verify this by looking in the last line of the About... dialog where it 
then says "background mode". If this is the case as I suppose, then 
running jEdit again will actually connect to the running jEdit instance 
and tell it what you want to do instead of starting jEdit again. Because 
of this I guess you have the described behaviour. You could disable the 
automatic startup of the jEdit server on system startup to change this 
behaviour, but then you have to wait longer for jEdit to start up as it 
has to start completely and not show only the GUI. For temporary tryout 
of the different behaviour you can also quit jEdit completely. If you 
use the upper right X to close the jEdit windows, you only close the GUI 
if jEdit is running in background mode and the jEdit server stays 
running. If you choose Quit from the File menu, then jEdit is completely 
quit and I guess the behaviour of your pinned item changes.

Regards
Vampire
