GtkHBox is a box container that packs child
widgets in a single row, using the packing methods inherited from
GtkBox, such as
pack_start() , as well as the less
flexible add() method available
to most container widgets. GtkHBox and
GtkVBox in combination are the most commonly
used packing widgets. See the GtkVBox constructor
for a working example using both.
Note that all children in a GtkHBox are allocated
the same height, regardless of settings and child requisition size.
Widgets taking up less than the allocated height are by default centered
within the available area in that dimension.
