Thank you Tadej for the clarification.
I tried substitute the gtk_button_new_from_stock for the
gtk_image_new_from_icon_name but, no errors occurs, but the image
isn't showed. What is showed is the broken GTK+ image.
A minimal version of my code, and attached the image:
#include <gtk/gtk.h>
int main(int argc, char *argv[])
{
GtkWidget *window, *scaleButton3;
GtkIconFactory *iconFactory;
GError *error = NULL;
gtk_init(&argc, &argv);
window = gtk_window_new(GTK_WINDOW_TOPLEVEL);
gtk_widget_set_size_request(window, 300, 175);
iconFactory = gtk_icon_factory_new();
gtk_icon_factory_add(iconFactory, "my-icon",
gtk_icon_set_new_from_pixbuf(gdk_pixbuf_new_from_file("icon.jpg",
&error)));
if(error)
{
g_print("\n%s", error->message);
}
gtk_icon_factory_add_default(iconFactory);
scaleButton3 = gtk_image_new_from_icon_name("my-icon",
GTK_ICON_SIZE_BUTTON);
gtk_container_add(GTK_CONTAINER(window), scaleButton3);
gtk_widget_show_all(window);
gtk_main();
return 0;
}
