Multi-threaded GUI

["Melvin Newman" <zexelon gmail com>]

My saga towards updating the GUI continues... the following are two code snippets:

1) My window update function. It is built into the window1 class and is supposed to update the main GUI window:

gboolean window1::updater(gpointer data)
{
    /* Variables
    ******************************************/
        Glib::RefPtr<Gdk::Window>win = get_window();
    /*****************************************/
    
    if(win)
    {
        Gdk::Rectangle r(0, 0, get_allocation().get_width(),get_allocation().get_height());
        win->invalidate_rect(r, false);
    }
    return(true);
}


2) The following is my thread that calls this function through the g_idle_add() function... Unfortunately it does not compile at this line and being new to OO/C++ I have no idea why, or how to fix the problem:

void *server_connect(void *ptr)
{
    /* Variables
    ******************************************/
        int tmp=0;
        int socket_id;
        struct sockaddr_in address;
        gpointer data;
        Glib::RefPtr<Gtk::TextBuffer> buffer;
        sigc::connection pipe1;
    /*****************************************/
    
    socket_id = pthread_arg.socket_id;
    address = pthread_arg.address;
    buffer = pthread_arg.out_put_buffer;
        
    do
    {
        tmp = connect (socket_id,(struct sockaddr *) &address, sizeof(struct sockaddr));
        if (tmp <0)
        {
            buffer->insert_at_cursor("@");
            
            g_idle_add(window1::updater,false); 
               ^-- Compiling stops here with: error: invalid use of non-static member function `gboolean window1::updater(void*)'
            
            Glib::usleep(400000);
        }
        
    }while(tmp<0);
    
}

Unfortunately I cant seem to integrate the server_connect function into the class, because pthread then complains that it can not call it (miss mach type).

Any help would be greatly appreciated.

Sincerely
Melvin Newman
