Package: Size_Group

Description

package Gtk.Size_Group is
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_Size_Group 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 Fill flag. </description>
