While gtk-doc doesn't care, this isn't really valid Markdown as the GtkBuilder custom XML tags will be considered valid markup and embedded as they are, breaking the HTML output.

/**

* SECTION:gtksizegroup
|
||
* @Short_description: Grouping widgets so they request the same size
|
||
* @Title: GtkSizeGroup
|
||
*
|
||
* #GtkSizeGroup provides a mechanism for grouping a number of widgets
|
||
* together so they all request the same amount of space. This is
|
||
* typically useful when you want a column of widgets to have the same
|
||
* size, but you can’t use a #GtkGrid widget.
|
||
*
|
||
* In detail, the size requested for each widget in a #GtkSizeGroup is
|
||
* the maximum of the sizes that would have been requested for each
|
||
* widget in the size group if they were not in the size group. The mode
|
||
* of the size group (see gtk_size_group_set_mode()) determines whether
|
||
* this applies to the horizontal size, the vertical size, or both sizes.
|
||
*
|
||
* Note that size groups only affect the amount of space requested, not
|
||
* the size that the widgets finally receive. If you want the widgets in
|
||
* a #GtkSizeGroup to actually be the same size, you need to pack them in
|
||
* such a way that they get the size they request and not more. For
|
||
* example, if you are packing your widgets into a table, you would not
|
||
* include the %GTK_FILL flag.
|
||
*
|
||
* #GtkSizeGroup objects are referenced by each widget in the size group,
|
||
* so once you have added all widgets to a #GtkSizeGroup, you can drop
|
||
* the initial reference to the size group with g_object_unref(). If the
|
||
* widgets in the size group are subsequently destroyed, then they will
|
||
* be removed from the size group and drop their references on the size
|
||
* group; when all widgets have been removed, the size group will be
|
||
* freed.
|
||
*
|
||
* Widgets can be part of multiple size groups; GTK+ will compute the
|
||
* horizontal size of a widget from the horizontal requisition of all
|
||
* widgets that can be reached from the widget by a chain of size groups
|
||
* of type %GTK_SIZE_GROUP_HORIZONTAL or %GTK_SIZE_GROUP_BOTH, and the
|
||
* vertical size from the vertical requisition of all widgets that can be
|
||
* reached from the widget by a chain of size groups of type
|
||
* %GTK_SIZE_GROUP_VERTICAL or %GTK_SIZE_GROUP_BOTH.
|
||
*
|
||
* Note that only non-contextual sizes of every widget are ever consulted
|
||
* by size groups (since size groups have no knowledge of what size a widget
|
||
* will be allocated in one dimension, it cannot derive how much height
|
||
* a widget will receive for a given width). When grouping widgets that
|
||
* trade height for width in mode %GTK_SIZE_GROUP_VERTICAL or %GTK_SIZE_GROUP_BOTH:
|
||
* the height for the minimum width will be the requested height for all
|
||
* widgets in the group. The same is of course true when horizontally grouping
|
||
* width for height widgets.
|
||
*
|
||
* Widgets that trade height-for-width should set a reasonably large minimum width
|
||
* by way of #GtkLabel:width-chars for instance. Widgets with static sizes as well
|
||
* as widgets that grow (such as ellipsizing text) need no such considerations.
|
||
*
|
||
* # GtkSizeGroup as GtkBuildable
|
||
*
|
||
* Size groups can be specified in a UI definition by placing an `<object>`
|
||
* element with `class="GtkSizeGroup"` somewhere in the UI definition. The
|
||
* widgets that belong to the size group are specified by a `<widgets>` element
|
||
* that may contain multiple `<widget>` elements, one for each member of the
|
||
* size group. The ”name” attribute gives the id of the widget.
|
||
*
|
||
* An example of a UI definition fragment with GtkSizeGroup:
|
||
*
|
||
* |[<!-- language="xml" -->
|
||
* <object class="GtkSizeGroup">
|
||
* <property name="mode">GTK_SIZE_GROUP_HORIZONTAL</property>
|
||
* <widgets>
|
||
* <widget name="radio1"/>
|
||
* <widget name="radio2"/>
|
||
* </widgets>
|
||
* </object>
|
||
* ]|
