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, <firstterm>size requisition</firstterm> and <firstterm>size

with its parent and its children. The basic form of this negotiation is
carried out in two phases, <firstterm>size requisition</firstterm> and
<firstterm>size allocation</firstterm>, which are implemented by the
size_request() and size_allocate() virtual functions in #GtkWidget.

GTK+ also supports a more complicated form of size negotiation called
<firstterm>width-for-height</firstterm> (and its dual
<firstterm>height-for-width</firstterm>). See #GtkExtendedLayout
to learn more about width-for-height geometry management.
