Hi all,
I think I've got an understanding problem of GTK. My simple application has a stream of images and I'd like to display them within my GTK Window. Up to now, it looks like this:
GdkPixbuf *pb = gdk_pixbuf_new_from_data(img2, GDK_COLORSPACE_RGB,
FALSE, 24/3, 320, 240, 320*3,
NULL, NULL);
if(pb == NULL)
fprintf(stderr, "Pixbuf is null!\n");
if(image != NULL)
gtk_container_remove(GTK_CONTAINER(window), image);
image = gtk_image_new_from_pixbuf(pb);
gtk_container_add(GTK_CONTAINER(window), image);
printf("Updated!\n");
img2 is my (rgb) buffer that gets updated from a stream each time. I guess gtk_container_remove and gtk_container_add might be stupid to use for this?
Here's what I've got in addition:
GtkWidget *window;
GtkWidget *image;
gtk_init(&argc, &argv);
window = gtk_window_new(GTK_WINDOW_TOPLEVEL);
gtk_signal_connect(GTK_OBJECT(window), "destroy",
GTK_SIGNAL_FUNC(destroy), NULL);
/* ... */
start_routine_for_stream_that_calls_the_above(...)
/* ... */
gtk_widget_show_all(window);
gtk_main();
My problem is that it's not working this way... either I see only the last GdkPixbuf image or I see none, which is the correct behaviour ...
But how do I manage it to show an (stream of) updated GdkPixbuf?
Thanks for help
