AFAIK there is nothing to stop people from running multiple GUI toolkits
at the same time. After all, Qt ships with wrappers that can handle Motif
widgets within a Qt application. I am not a specialist on GUI toolkits
how-ever...
So it seems possible to run GUIs of different GUI toolkits within each
other. I would not how-ever count on hosts being able to run any
particular GUI toolkit widgets that did fit the plugin developer's fancy.
The route taken in ladspa gui round 2 (separate processes for GUIs) may be
poor from user's point of view, but at least it is better than no
customized GUIs. Hopefully someone proves I am wrong.
PS. The thing you are asking for (miltiple plugins GUIs within one window)
is exactly the way Mustajuuri handles these things.
PPS. Every few minutes slashdot comes with an example of people running
Gnome apps within a KDE app. I do not know if that is related to this.
Tommi.
