I'm creating a new JFrame from within an already running JFrame. Both frames are separate applications, but in this case, the second application gets a "plugin handle" of the first application instead of using its default stuff. For some operations in the second app, a callback is made to the first app to know what to do/display.
This way, the second application can be reused by many other applications. It is and will NOT be possible to manually start some java.exe command to achieve a real separate process.
Now, to emphasize that the second JFrame is another application, I want the taskbar entry to not be grouped together with the entry that was already there for the first JFrame. So basically this is a Windows 7 issue in combination with Java.
The icons on the taskbar are grouped together by default, there is enough space for them to be displayed separately but they simply don't.
How can I display the JFrame's icons separately on the taskbar? I can't find anything on JFrame that does what I want.
