<p>The GtkBox widget organizes child widgets into a rectangular area.</p>
<p>The rectangular area of a GtkBox is organized into either a single row
or a single column of child widgets depending upon the orientation.
Thus, all children of a GtkBox are allocated one dimension in common,
which is the height of a row, or the width of a column.</p>
<p>The GtkBox widget arranges child widgets into a single row or column,
depending upon the value of its <a class="link" href="gtk3-Orientable.html#GtkOrientable--orientation" title="The “orientation” property"><span class="type">“orientation”</span></a> property. Within
the other dimension, all children are allocated the same size. Of course,
the <a class="link" href="GtkWidget.html#GtkWidget--halign" title="The “halign” property"><span class="type">“halign”</span></a> and <a class="link" href="GtkWidget.html#GtkWidget--valign" title="The “valign” property"><span class="type">“valign”</span></a> properties can be used on
the children to influence their allocation.</p>
<p>GtkBox uses a notion of packing. Packing refers
