Re: [sc-dev] Cocoa primitives

[crucial felix <felix@xxxxxxxxxxxxxxxxxxx>]

something like this (from SCView::keyDown)

    PyrSymbol *method = getsym("ok");
    pthread_mutex_lock (&gLangMutex);
        VMGlobals *g = gMainVMGlobals;
        g->canCallOS = true;
        ++g->sp;  SetObject(g->sp, receiver);
        runInterpreter(g, method, 1);
        g->canCallOS = false;
    pthread_mutex_unlock (&gLangMutex);


pthread_mutex_lock waits till it gets the lock, right ?

nothing needs to be passed back to the method, since the CocoaDialog
instance still holds the original returnSlot object.

so this system should work for getting paths, strings, colors etc.
