Re: Problem with memory management with builder.

It become really strange when I additionally put treeview in glade. When I trying to delete treeview I get double delete and segmentation fault, but still it looks like button is not freed automatically.

Hi *,

I was told that deleting a window object (created by gtk builder) will cause deletion of every window's child. Maybe I'm wrong but it looks like it does not.

Take a look on this small piece of code

[code]

int main(int argc, char** argv)

{

Gtk::Button* button;

{

    Gtk::Main kit(argc, argv);

    Gtk::Window* window;

    Glib::RefPtr<Gtk::Builder> refBuilder = Gtk::Builder::create();

    refBuilder->add_from_file("some.ui"); // with window and button

    refBuilder->get_widget("window1", window);

    refBuilder->get_widget("button1", button);

    window->show_all();

    kit.run(*window);

    delete window;

} // builder dies here..

delete button;  // Program exits normally, no double delete.

}

[/code]

Why it behave so? I run this program in a loop (100 times) and memory usage still increasing. Even valgrind shows definitely lost memory.
