</h1><div class="doc"><p>A single radio button performs the same basic function as a
<code><a href="Graphics-UI-Gtk-Buttons-CheckButton.html#t:CheckButton">CheckButton</a></code>, as its position in the object hierarchy reflects. It is only
when multiple radio buttons are grouped together that they become a
different user interface component in their own right.
</p><p>Every radio button is a member of some group of radio buttons. When one
is selected, all other radio buttons in the same group are deselected. A
<code><a href="Graphics-UI-Gtk-Buttons-RadioButton.html#t:RadioButton">RadioButton</a></code> is one way of giving the user a choice from many options.
</p><p>Radio button widgets are created with <code><a href="Graphics-UI-Gtk-Buttons-RadioButton.html#v:radioButtonNew">radioButtonNew</a></code>.
Optionally, <code><a href="Graphics-UI-Gtk-Buttons-RadioButton.html#v:radioButtonNewWithLabel">radioButtonNewWithLabel</a></code> can be used if you want a
text label on the radio button.
</p><p>For the radio button functions that take an existing group, the groups are
represented by any of their members. So when adding widgets to an existing
group of radio buttons, use <code><a href="Graphics-UI-Gtk-Buttons-RadioButton.html#v:radioButtonNewFromWidget">radioButtonNewFromWidget</a></code> with a <code><a href="Graphics-UI-Gtk-Buttons-RadioButton.html#t:RadioButton">RadioButton</a></code>
that is already a member of the group. The convenience function
<code><a href="Graphics-UI-Gtk-Buttons-RadioButton.html#v:radioButtonNewWithLabelFromWidget">radioButtonNewWithLabelFromWidget</a></code> is also provided.
</p><p>To remove a <code><a href="Graphics-UI-Gtk-Buttons-RadioButton.html#t:RadioButton">RadioButton</a></code> from one group and make it part of a new one,
use <code><a href="Graphics-UI-Gtk-Buttons-RadioButton.html#v:radioButtonSetGroup">radioButtonSetGroup</a></code>.
</p><ul><li> How to create a group of two radio buttons.

createRadioButtons = do
window <- windowNew

</pre><p>When an unselected button in the group is clicked the clicked button
receives the "toggled" signal, as does the previously selected button.
Inside the "toggled" handler,
<code>Graphics.UI.Gtk.Buttons.ToggleButton.toggleButtonGetActive</code> can be used to
determine if the button has been selected or deselected.
