class provides common attributes and methods for a large number of widget
subclasses that manage the layout of other widgets within the area of a
window.</p><p>A <code class="literal">PyGTK</code> user interface is constructed by
nesting widgets inside widgets. Container widgets are the inner nodes in the
resulting tree of widgets: they contain other widgets. So, for example, you
might have a <a class="link" href="class-gtkwindow.html" title="gtk.Window"><code class="classname">gtk.Window</code></a>
containing a <a class="link" href="class-gtkframe.html" title="gtk.Frame"><code class="classname">gtk.Frame</code></a> containing
a <a class="link" href="class-gtklabel.html" title="gtk.Label"><code class="classname">gtk.Label</code></a>. If
you wanted an image instead of a textual label inside the frame, you might
replace the <a class="link" href="class-gtklabel.html" title="gtk.Label"><code class="classname">gtk.Label</code></a> widget with
a <a class="link" href="class-gtkimage.html" title="gtk.Image"><code class="classname">gtk.Image</code></a>
widget.</p><p>There are two major kinds of container widgets. Both are
subclasses of the abstract <a class="link" href="class-gtkcontainer.html" title="gtk.Container"><code class="classname">gtk.Container</code></a>
base class.</p><p>The first type of container widget has a single child widget and
derives from <a class="link" href="class-gtkbin.html" title="gtk.Bin"><code class="classname">gtk.Bin</code></a>. These
containers are decorators, that add some kind of functionality to the
child. For example, a <a class="link" href="class-gtkbutton.html" title="gtk.Button"><code class="classname">gtk.Button</code></a> makes its
child into a clickable button; a <a class="link" href="class-gtkframe.html" title="gtk.Frame"><code class="classname">gtk.Frame</code></a> draws a
frame around its child and a <a class="link" href="class-gtkwindow.html" title="gtk.Window"><code class="classname">gtk.Window</code></a> places
its child widget inside a top-level window.</p><p>The second type of container can have more than one child; its
purpose is to manage layout. This means that these containers assign sizes
and positions to their children. For example, a <a class="link" href="class-gtkhbox.html" title="gtk.HBox"><code class="classname">gtk.HBox</code></a> arranges its
children in a horizontal row, and a <a class="link" href="class-gtktable.html" title="gtk.Table"><code class="classname">gtk.Table</code></a> arranges
the widgets it contains in a two-dimensional grid.</p><p>To fulfill its task, a layout container must negotiate the size
requirements with its parent and its children. This negotiation is carried
out in two phases, size requisition and size allocation.</p><div class="refsect2" title="Size Requisition"><a name="sec-ContainerSizeRequisition"></a><h3>Size Requisition</h3><p>The size requisition of a widget is it's desired width and
height. This is represented by a <a class="link" href="class-gtkrequisition.html" title="gtk.Requisition"><code class="classname">gtk.Requisition</code></a>.</p><p>How a widget determines its desired size depends on the
widget. A <a class="link" href="class-gtklabel.html" title="gtk.Label"><code class="classname">gtk.Label</code></a>, for
example, requests enough space to display all its text. Container widgets
generally base their size request on the requisitions of their
children.</p><p>The size requisition phase of the widget layout process operates
top-down. It starts at a top-level widget, typically a GtkWindow. The
top-level widget asks its child for its size requisition by calling
gtk_widget_size_request(). To determine its requisition, the child asks its
own children for their requisitions and so on. Finally, the top-level widget
will get a requisition back from its child.</p></div><div class="refsect2" title="Size Allocation"><a name="sec-ContainerSizeAllocation"></a><h3>Size Allocation</h3><p>When the top-level widget has determined how much space its
child would like to have, the second phase of the size negotiation, size
allocation, begins. Depending on its configuration (see the <a class="link" href="class-gtkwindow.html#method-gtkwindow--set-resizable" title="gtk.Window.set_resizable"><code class="methodname">gtk.Window.set_resizable</code>()</a>
method), the top-level widget may be able to expand in order to satisfy the
size request or it may have to ignore the size request and keep its fixed
size. It then tells its child widget how much space it gets by calling the
<a class="link" href="class-gtkwidget.html#method-gtkwidget--size-allocate" title="gtk.Widget.size_allocate"><code class="methodname">size_allocate</code>()</a>
method. The child widget divides the space among its children and tells each
child how much space it got, and so on. Under normal circumstances, a <a class="link" href="class-gtkwindow.html" title="gtk.Window"><code class="classname">gtk.Window</code></a> will
always give its child the amount of space the child requested.</p><p>A child's size allocation is represented by a <a class="link" href="class-gdkrectangle.html" title="gtk.gdk.Rectangle"><code class="classname">gtk.gdk.Rectangle</code></a>
that contains not only a width and height, but also a position (i.e. X and Y
coordinates), so that containers can tell their children not only how much
space is available, but also where they are positioned inside the space
available to the container.</p><p>Widgets are required to honor the size allocation they receive;
a size request is only a request, and widgets must be able to cope with any
size.</p></div><div class="refsect2" title="Child Properties"><a name="sec-ContainerChildProperties"></a><h3>Child Properties</h3><p><a class="link" href="class-gtkcontainer.html" title="gtk.Container"><code class="classname">gtk.Container</code></a>
