Gtk2::Ex::FormFactory::RadioButton - A RadioButton in a FormFactory framework

SYNOPSIS

Top

  Gtk2::Ex::FormFactory::RadioButton->new (
    value => Value this RadioButton sets in the associated
             application object attribute,
    ...
    Gtk2::Ex::FormFactory::Widget attributes
  );

DESCRIPTION

Top

This class implements a RadioButton in a Gtk2::Ex::FormFactory framework. The activation state of the RadioButton is controlled by the value of the associated application object attribute.

All RadioButton's which should be grouped together need to be added to the same container resp. they must have the same parent.

ATTRIBUTES

Top

Attributes are handled through the common get_ATTR(), set_ATTR() style accessors, but they are mostly passed once to the object constructor and must not be altered after the associated FormFactory was built.

value = SCALAR [optional]

This value is transferred to the attribute of the associated application object when the RadioButton is activated.

For more attributes refer to Gtk2::Ex::FormFactory::Widget.
