GtkGrid is a container which arranges its child widgets in rows and columns. It is a very similar to GtkTable and GtkBox, but it consistently uses GtkWidget's GtkWidget:margin and GtkWidget:expand properties instead of custom child properties, and it fully supports <link linkend="geometry-management">height-for-width geometry management</link>. Children are added using gtk_grid_attach(). They can span multiple rows or columns. It is also possible to add a child next to an existing child, using gtk_grid_attach_next_to(). GtkGrid can be used like a GtkBox by just using gtk_container_add(), which will place children next to each other in the direction determined by the GtkOrientable:orientation property.
