.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 GtkTable
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 gtkSizeGroupSetMode
) 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 gObjectUnref()
. 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
.gtkSizeGroup
is the equivalent of gtkSizeGroupNew
.ignore-hidden
[logical : Read / Write]TRUE
, unmapped widgets are ignored when determining
the size of the group.
