\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.)
