Hi all, my first post here. Bear with me, I'm also new to Gtk...
Rather than posting alot of code I'll try to describe my problem on a more conceptual level and would like to hear if what I'm trying to do and how I go about it seems sound. I have an industrial camera from which I can manage to grab and save to disk as many pictures as I like. I do this in a loop which resides in a callback function which is called when the take pictures button is clicked. Number of pictures to take is specified by the user in a GtkTextEntry. So far so good. What I also want is that a GtkImage-widget should be updated to immediately display each new picture. This doesn't happen. Only the last picture taken will be displayed and this happens exactly when the "take pictures"-button callback returns. I guess the gtk-main loop has my request for widget update [gtk_image_set_from_pixbuf(snapshot, pixbuf)] queued and will do my request after it's done with the callback. I've tried some functions like gtk_widget_show_now and gtk_widget_queue_draw right after the call to gtk_image_set_from_pixbuf(snapshot, pixbuf), to no avail, obviously. Any suggestions would be so welcome! |
