Hi Jeremy,

There are a number of ways to do this.  The most common is to
encapsulate your data in your druid in a struct, and pass that around as
your user_data.  Another option (which is fine for quick and dirty
dialogs and the like) is to use gtk_object_[gs]et_data.  As an example:

gtk_object_set_data (GTK_OBJECT (druid), "foo", foo);
gtk_object_set_data (GTK_OBJECT (druid), "bar", bar);

...


foo = gtk_object_get_data (GTK_OBJECT (druid), "foo");
bar = gtk_object_get_data (GTK_OBJECT (druid), "bar");


Thanks,
