What is the difference between MainWindows show() and showAll() method in GtkD?

Question

Here is my test:

import gtk.Main;
import gtk.MainWindow;
import gtk.Label;

void main(string[] args)
{
    Main.init(args);
    auto window = new MainWindow("My Window");
    window.add(new Label("Label1"));
    window.show();
    Main.run();
}

When I replace Main.show() with Main.showAll() it works as expected, however I can't find any documentation for either function here: http://api.gtkd.org/src/gtk/MainWindow.html What is the difference between these two methods and where can I find documentation?

These links from official GTK+ documentation should help: gtk_widget_show, gtk_widget_show_all. In short, show shows only the widget it is called on, and show_all, being applied to a container, shows all widgets in this container recursively.

GtkD has very poor and nearly impossible to use API docs, though this seems to be a problem not of GtkD but of D tools. The methods you are referring to are defined on GtkWidget class, but unfortunately the page about gtk.Widget is empty (mostly).
