Hi,
>From reading the documentation, I am expecting a GWeakNotify to be
fired when the object is finalized (which I interpret as right before
it is freed). However, I am seeing it called during destroy while
references are still held. I am likely just misunderstanding
something, any explanations? Thanks...
$ ./weak
created widget, ref count 1
in container, ref count 2
Finalize, ref count 2
destroyed container 1
destroying last ref 1
$ cat weak.cc
#include <stdio.h>
#include <gtk/gtk.h>
static void OnFinalizeDebug(gpointer userdata, GObject* wasptr) {
printf("Finalize, ref count %d\n", wasptr->ref_count);
}
int main(int argc, char** argv) {
gtk_init(&argc, &argv);
GtkWidget* widget = gtk_label_new("abc");
g_object_ref_sink(widget);
g_object_weak_ref(G_OBJECT(widget), OnFinalizeDebug, &widget);
printf("created widget, ref count %d\n", G_OBJECT(widget)->ref_count);
GtkWidget* box = gtk_vbox_new(FALSE, 0);
gtk_container_add(GTK_CONTAINER(box), widget);
printf("in container, ref count %d\n", G_OBJECT(widget)->ref_count);
gtk_widget_destroy(box);
printf("destroyed container %d\n", G_OBJECT(widget)->ref_count);
printf("destroying last ref %d\n", G_OBJECT(widget)->ref_count);
g_object_unref(widget);
return 0;
}
