thanks, when I launch a simple app with this code it works :
#import <Cocoa/Cocoa.h>
#import "MyOgView.h"

int main(int argc, char *argv[])

process

    //voir -[NSApplication runModalForWindow:].

    ogView = [[MyOgView alloc]

    window = [[NSWindow alloc]  
initWithContentRect:NSMakeRect(50,100,640,480)
                                          
styleMask:NSTitledWindowMask | NSResizableWindowMask
                                            
backing:NSBackingStoreBuffered
                                             defer:TRUE];

Try allocating the windows and views after the application object  
exists.  Windows register themselves in the application's window list.



        const ProcessSerialNumber psn = { 0, kCurrentProcess };
    TransformProcessType(&psn,  
kProcessTransformToForegroundApplication);


    SetFrontProcess(&psn);

    //add title to the window
    [window setTitle:@"toto gl"];


    //attach glview on the window
    [[window contentView] addSubview:ogView];
    //[[window contentView] addSubview:button];


    [NSApplication sharedApplication];
    [window makeKeyAndOrderFront: nil];
    [pool release];

    [NSApp run];
    return 0;
}

But when I use this code in a dynamic library it not work, I can't  
see the window, have you got an idea ?

I'm not sure.  What kind of program is loading the library?  Also, is  
it being run from a GUI login session (as opposed to, for example, an  
ssh session or cron job)?

What else can you tell us about the situation?

Regards,
Ken
