GtkButtonBox

<!-- ##### SECTION Short_Description ##### -->
Base class for #GtkHButtonBox and #GtkVButtonBox

<!-- ##### SECTION Long_Description ##### -->
<para>
The primary purpose of this class is to keep track of the various properties
of #GtkHButtonBox and #GtkVButtonBox widgets.
</para>
<para>
gtk_button_box_get_child_size_default() retrieves the default minimum width and height 
for widgets in any button box. gtk_button_box_set_child_size_default()
changes the default minimum child widget size.
</para>
<para>
gtk_button_box_get_child_size() retrieves the minimum width and height 
for widgets in a given button box. gtk_button_box_set_child_size() 
allows those properties to be changed.
</para>
<para>
gtk_button_box_get_child_ipadding_default() gets the default number of pixels of 
horizontal and vertical padding that are applied to each button in every button box.
gtk_button_box_set_child_ipadding_default() allows these defaults to be
changed.
</para>
<para>
The internal padding of buttons can be retrieved and changed per button box using
gtk_button_box_get_child_ipadding() and gtk_button_box_set_child_ipadding()
respectively.
</para>
<para>
gtk_button_box_get_spacing() and gtk_button_box_set_spacing() retrieve and
change default number of pixels between buttons, respectively.
</para>
<para>
gtk_button_box_get_layout() and gtk_button_box_set_layout() retrieve and alter the method
used to spread the buttons in a button box across the container, respectively.
</para>

<!-- ##### STRUCT GtkButtonBox ##### -->
<para>
This is a read-only struct; no members should be modified directly.
</para>


<!-- ##### MACRO GTK_BUTTONBOX_DEFAULT ##### -->
<para>
Used internally only.
</para>



<!-- ##### FUNCTION gtk_button_box_get_child_size_default ##### -->
<para>
Retrieves the default minimum width and height for all button boxes, and
places the values in @min_width and @min_height, respectively.
</para>

@min_width: the default minimum width of a child widget.
@min_height: the default minimum height of a child widget.


<!-- ##### FUNCTION gtk_button_box_get_child_ipadding_default ##### -->
<para>
The internal padding of a button is the amount of space between the outside
of the button and the widget it contains. This function gets the default
amount of horizontal and vertical padding, placing the results in @ipad_x
and @ipad_y, respectively.
</para>

@ipad_x: the default horizontal internal button padding.
@ipad_y: the default vertical internal button padding.


<!-- ##### FUNCTION gtk_button_box_set_child_size_default ##### -->
<para>
Sets the default size of child buttons.
</para>

@min_width: minimum default width for child buttons.
@min_height: minimum default height for child buttons.


<!-- ##### FUNCTION gtk_button_box_set_child_ipadding_default ##### -->
<para>
Sets the default number of pixels that pad each button in every button box.
</para>

@ipad_x: new default horizontal padding.
@ipad_y: new default vertical padding.


<!-- ##### FUNCTION gtk_button_box_get_spacing ##### -->
