<p>
The primary purpose of this class is to keep track of the various properties
of <a href="GtkHButtonBox.html" title="GtkHButtonBox"><span class="type">GtkHButtonBox</span></a> and <a href="GtkVButtonBox.html" title="GtkVButtonBox"><span class="type">GtkVButtonBox</span></a> widgets.
</p>
<p>
<a href="GtkButtonBox.html#gtk-button-box-get-child-size"><code class="function">gtk_button_box_get_child_size()</code></a> retrieves the minimum width and height
for widgets in a given button box. <a href="GtkButtonBox.html#gtk-button-box-set-child-size"><code class="function">gtk_button_box_set_child_size()</code></a>
allows those properties to be changed.
</p>
<p>
The internal padding of buttons can be retrieved and changed per button box using
<a href="GtkButtonBox.html#gtk-button-box-get-child-ipadding"><code class="function">gtk_button_box_get_child_ipadding()</code></a> and <a href="GtkButtonBox.html#gtk-button-box-set-child-ipadding"><code class="function">gtk_button_box_set_child_ipadding()</code></a>
respectively.
</p>
<p>
<a href="GtkButtonBox.html#gtk-button-box-get-spacing"><code class="function">gtk_button_box_get_spacing()</code></a> and <a href="GtkButtonBox.html#gtk-button-box-set-spacing"><code class="function">gtk_button_box_set_spacing()</code></a> retrieve and
change default number of pixels between buttons, respectively.
</p>
<p>
<a href="GtkButtonBox.html#gtk-button-box-get-layout"><code class="function">gtk_button_box_get_layout()</code></a> and <a href="GtkButtonBox.html#gtk-button-box-set-layout"><code class="function">gtk_button_box_set_layout()</code></a> retrieve and alter the method
used to spread the buttons in a button box across the container, respectively.
</p>
<p>
The main purpose of GtkButtonBox is to make sure the children have all the same size.
Therefore it ignores the homogeneous property which it inherited from GtkBox, and always
behaves as if homogeneous was <a

Sets whether <em class="parameter"><code>child</code></em> should appear in a secondary group of children.
A typical use of a secondary child is the help button in a dialog.
</p>
<p>
This group appears after the other children if the style
is <a href="gtk-Standard-Enumerations.html#GTK-BUTTONBOX-START:CAPS"><code class="literal">GTK_BUTTONBOX_START</code></a>, <a href="gtk-Standard-Enumerations.html#GTK-BUTTONBOX-SPREAD:CAPS"><code class="literal">GTK_BUTTONBOX_SPREAD</code></a> or

is <a href="gtk-Standard-Enumerations.html#GTK-BUTTONBOX-END:CAPS"><code class="literal">GTK_BUTTONBOX_END</code></a>. For horizontal button boxes, the definition
of before/after depends on direction of the widget (see

the other end of the button box from the main children. For the
other styles, they appear immediately next to the main children.</p>
