group -- an existing gtk:radio-tool-button group, or nil if you are creating a new group
stock -- a string with the name of a stock item

The new gtk:radio-tool-button widget.

Creates a new radio tool button, adding it to group. The new radio tool button will contain an icon and label from the stock item indicated by stock. The gtk:radio-tool-button-new-from-stock function has been deprecated since version 3.10 and should not be used in newly written code. Use the gtk:radio-tool-button-new function instead.
