</h1><div class="doc"><p>The primary purpose of this class is to keep track of the various
properties of <code><a href="Graphics-UI-Gtk-Layout-HButtonBox.html#t:HButtonBox">HButtonBox</a></code> and <code><a href="Graphics-UI-Gtk-Layout-VButtonBox.html#t:VButtonBox">VButtonBox</a></code> widgets.
</p><p><code>buttonBoxGetChildSize</code> retrieves the minimum width and height for
widgets in a given button box. <code>buttonBoxSetChildSize</code> allows those
properties to be changed.
</p><p>The internal padding of buttons can be retrieved and changed per button
box using <code>buttonBoxGetChildIpadding</code> and <code>buttonBoxSetChildIpadding</code>
respectively.
</p><p><code>buttonBoxGetSpacing</code> and <code>buttonBoxSetSpacing</code> retrieve and change
default number of pixels between buttons, respectively.
</p><p><code><a href="Graphics-UI-Gtk-Abstract-ButtonBox.html#v:buttonBoxGetLayout">buttonBoxGetLayout</a></code> and <code><a href="Graphics-UI-Gtk-Abstract-ButtonBox.html#v:buttonBoxSetLayout">buttonBoxSetLayout</a></code> retrieve and alter the
method used to spread the buttons in a button box across the container,
respectively.
</p><p>The main purpose of <code><a href="Graphics-UI-Gtk-Abstract-ButtonBox.html#t:ButtonBox">ButtonBox</a></code> is to make sure the children have all the
same size. Therefore it ignores the homogeneous property which it inherited
from <code><a href="Graphics-UI-Gtk-Abstract-Box.html#t:Box">Box</a></code>, and always behaves as if homogeneous was <code>True</code>.
