[Glade-users] Change an PNG image by athother!

[peter_t_mayer yahoo de (Peter T. Mayer)]

I hope that I understood you right, if not so please tell me more exact 
what you want:


GError *err= NULL;
// load a new image from file
// the gdk_pixbuf... functions provide also image manipulation functionality
GdkPixbuf *buf= gdk_pixbuf_new_from_file ( 
"PATH_TO_PIC/PICTURE_NAME.png", &err );

// Then you can lookup the glade generated image name (= Widget Name
// in the glade Properties Dialog)
GtkWidget *widget= lookup_widget (dialog, "WIDGET_NAME");
// now set the new loaded image instead of the old image:
gtk_image_set_from_pixbuf( GTK_IMAGE( widget ), buf);
// do not forget to unref your pic (so that the memory is freed)
gdk_pixbuf_unref( buf );

Tino!
