<h2>Detailed Description</h2>
<p>The Q3HBox widget provides horizontal geometry management for its child widgets.</p>
<p>All the horizontal box's child widgets will be placed alongside each other and sized according to their <a href="q3hbox.html#sizeHint">sizeHint</a>()s.</p>
<p>Use <a href="q3frame.html#margin-prop">setMargin</a>() to add space around the edges, and use <a href="q3hbox.html#setSpacing">setSpacing</a>() to add space between the widgets. Use <a href="q3hbox.html#setStretchFactor">setStretchFactor</a>() if you want the widgets to be different sizes in proportion to one another. (See <a href="layout.html">Layouts</a> for more information on stretch factors.)</p>
