Description

gtk.SizeGroup 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 gtk.Table widget. The size requested for each widget in a gtk.SizeGroup 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 set_mode() and the GTK SizeGroup Mode Constants) 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 gtk.SizeGroup 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. gtk.SizeGroup objects are referenced by each widget in the size group, so once you have added all widgets to a gtk.SizeGroup. 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; PyGTK 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.

Constructor

    gtk.SizeGroup(mode)

Creates a new gtk.SizeGroup with the mode specified by the value of mode which is one of the GTK SizeGroup Mode Constants.
