A window which will likely contain the rest of the application.
A window is the framework that contains the application. It provides a context for the other widgets that make up the application.
As a subclass of GtkBin a window may only have one child. To add more widgets to a window first add a widget which can accept more than one child like a GtkHBox or a GtkVBox. Then add the other widgets to the child container. Trying to add more than one child will produce a warning.
<?php // Create a new window. $window = new GtkWindow(); // Add two buttons. $window->add(new GtkButton('1')); $window->add(new GtkButton('2')); /* Spits out: Gtk-WARNING **: Attempting to add a widget with type GtkButton to a GtkWindow, but as a GtkBin subclass a GtkWindow can only contain one widget at a time; it already contains a widget of type GtkButton */ ?>
GtkWindow is a top level widget. This means that it may not be added as a child of another widget. Trying to do so will produce a Gtk-WARNING.
