Dear all 
We are writing an apps to view a video. This video 
is loaded from a file and it's stored like RGB 
sequence without header.  
We made a window, and inside a loop we made a 
drawing area but we can't update it: 
 
window=gtk_window_new(GTK_WINDOW_TOPLEVEL); 
 
for(int i=0;i<250;i++) 
        { 
fin.read((gchar*)rgbbuf,IMAGE_WIDTH*IMAGE_HEIGHT*3); 
 
darea=gtk_drawing_area_new(); 
gtk_widget_set_size_request(darea,IMAGE_WIDTH,IMAGE_HEIGHT); 
 
gtk_signal_connect(GTK_OBJECT(darea),"expose-event",GTK_SIGNAL_FUNC(on_darea_expose),NULL); 
 
gtk_widget_show_all(window); 
 
gtk_widget_destroy(darea); 
} 
 
with the on_darea_expose function like this: 
 
gboolean on_darea_expose(GtkWidget 
*widget,GdkEventExpose *event, gpointer user_data) 
{ 
gdk_draw_rgb_image(widget->window,widget->style->fg_gc[GTK_STATE_NORMAL],0,0,IMAGE_WIDTH,IMAGE_HEIGHT,GDK_RGB_DITHER_MAX,rgbbuf,IMAGE_WIDTH*3);
 
 
return TRUE; 
} 
 
gtk_container_add(GTK_CONTAINER(window),darea); 
 
 
thanks a lot for your help..
