Hi Chris. Sorry for the delay. Ok, so here´s how I solved the situation with
FLTK and audio plugins - hope this works for you too:
First, I´m not using FL::run() or FL::wait(). What I do is have something like
this:
static int FLTK4VST::FLTK4VST_eventDispatcher_(int e, Fl_Window *w)
{
int ret = Fl::handle_(e, w);
if (ret)
Fl::flush();
return ret;
}
Then in the constructon of my plugin I have this:
FLTK4VST::FLTK4VST (VstInt16 width, VstInt16 height, void *fx) : AEffEditor (
(AudioEffect*)fx )
{
//...
fltkWindow_ = 0;
Fl::event_dispatch(FLTK4VST::FLTK4VST_eventDispatcher_);
//...
}
So the system will call my event dispatcher method, which in turn will send the
events to the standard FLTK event handler, but by checking FLTK´s handler
return value, I can force a redraw when it is actually needed).
Second, I have to control carefully the name of the window class that is being
registered by my plugin´s instance... I have this static function:
static void FLTK4VST::getXClassName_(char *name)
{
static int r1 = rand();
static int r2 = rand();
static int r3 = rand();
sprintf(name, "FLTK4VST_%d_%d_%d", r1, r2, r3);
}
Which ensures that every object of a given DLL will have a unique class name
(and different than the default "FLTK"), and whenever a different DLL is
loaded, any object of that other DLL will have a unique class name too (and
again, not "FLTK"). Since PS isn´t really unloading the DLL when closing the
plugin, this is stil important, even if you can´t have 2 plugins operating at
the same time. Of course my function isn´t perfect - relying on rand() isn´t
the most elegant solution but works as proof of concept.
Now, whenever I´m are ready to build and show my window, I´m doing this:
/////////////////////////////////////
if (fltkWindow_ == 0)
{
Fl::visual(FL_DOUBLE|FL_INDEX);
char name[256];
getXClassName_(name);
fltkWindow_ = new Fl_VST_Window(windowRect_.left + windowRect_.right,
windowRect_.top + windowRect_.bottom);
fltkWindow_->xclass(name);
fltkWindow_->set_override();
buildEditor_(); // Create the different widgets that make up your GUI
}
fltkWindow_->show();
//////////////////////////////////////
Finally, when you want to destroy your main plugin´s window:
////////////////////////////////////
#ifdef WIN32
char t[256];
getXClassName_(t);
BOOL res = UnregisterClass(t, 0);
#endif
Fl_VST_Window *tmpFltkWindow = fltkWindow_;
fltkWindow_ = 0;
delete tmpFltkWindow;
/////////////////////////////////////
For more information on why or how this is working you can chek the
Fl_X::make(Fl_Window* w) in the Fl_win32.cxx file and the Windows API.
Hope this works for you. And I really hope that all the code I´ve posted here
comes out formated the right way - I´ve had very bad luck with the formatting
of my posts in the past.

I´m at GMT -5, but as you can get from the time of both my previous post and
this one, I´m not getting much sleep lately. :D
Best regards,
Carlos
