\class Q3HBox | |
\brief The Q3HBox widget provides horizontal geometry management | |
for its child widgets. | |
\compat | |
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.) | |
