## Packing

When creating an application, you'll want to put more than one widget inside a window. Our first helloworld example only used one widget so we could simply use a `gtk_container_add()` call to "pack" the widget into the window. But when you want to put more than one widget into a window, it it becomes important to control how each widget is positioned and sized. This is where packing comes in.

GTK+ comes with a large variety of layout containers whose purpose it is to control the layout of the child widgets that are added to them. See Layout Containers for an overview.

The following example shows how the GtkGrid container lets you arrange several buttons:

Create a new file with the following content named example-2.c.

You can compile the program above with GCC using:

`gcc `pkg-config --cflags gtk+-3.0` -o example-2 example-2.c `pkg-config --libs gtk+-3.0``
