\class QHBox qhbox.h
\brief The QHBox widget provides horizontal geometry management
for its child widgets.
\ingroup organizers
\ingroup geomanagement
\ingroup appearance
All the horizontal box's child widgets will be placed alongside
each other and sized according to their sizeHint()s.
Use setMargin() to add space around the edges, and use
setSpacing() to add space between the widgets. Use
setStretchFactor() if you want the widgets to be different sizes
in proportion to one another. (See \link layout.html
Layouts\endlink for more information on stretch factors.)
