.. _wx.RadioButton:

==========================================================================================================================================
|phoenix_title|  **wx.RadioButton**
==========================================================================================================================================

A radio button item is a button which usually denotes one of several mutually exclusive options.          

It has a text label next to a (usually) round button. 

You can create a group of mutually-exclusive radio buttons by specifying  ``RB_GROUP``   for the first in the group. The group ends when another radio button group is created, or there are no more radio buttons. 





.. _RadioButton-styles:

|styles| Window Styles
================================

This class supports the following styles: 

  

- ``wx.RB_GROUP``: Marks the beginning of a new group of radio buttons.  
- ``wx.RB_SINGLE``: In some circumstances, radio buttons that are not consecutive siblings trigger a hang bug in Windows (only). If this happens, add this style to mark the button as not belonging to a group, and implement the mutually-exclusive group behaviour yourself.  








.. _RadioButton-events:

|events| Events Emitted by this Class
=====================================

Handlers bound for the following event types will receive a :ref:`wx.CommandEvent` parameter.


- EVT_RADIOBUTTON: Process a  ``wxEVT_RADIOBUTTON``   event, when the radiobutton is clicked.

.. class:: wx.RadioButton(Control)

   **Possible constructors**::

       RadioButton()
       
       RadioButton(parent, id=ID_ANY, label=EmptyString, pos=DefaultPosition,
                   size=DefaultSize, style=0, validator=DefaultValidator,
                   name=RadioButtonNameStr)
       
   
   A radio button item is a button which usually denotes one of several
   mutually exclusive options.

      :type `id`: wx.WindowID
      :param `label`: Label for the radio button.   
      :type `label`: string
      :param `pos`: Window position. If :ref:`wx.DefaultPosition`  is specified then a default position is chosen.   
      :type `pos`: wx.Point

   .. method:: Create(self, parent, id=ID_ANY, label=EmptyString, pos=DefaultPosition, size=DefaultSize, style=0, validator=DefaultValidator, name=RadioButtonNameStr)

      Creates the choice for two-step construction.                  

      See :ref:`wx.RadioButton`  for further details.                  


      :param `parent`: 
      :type `parent`: wx.Window
      :param `id`: 
      :type `id`: wx.WindowID

      :rtype: `bool`








   .. method:: GetValue(self)

      Returns ``True`` if the radio button is checked, ``False`` otherwise.                  

      :rtype: `bool`








   .. method:: SetValue(self, value)

      Sets the radio button to checked or unchecked status.                  

      This does not cause a  ``wxEVT_RADIOBUTTON``   event to get emitted. 

      If the radio button belongs to a radio group exactly one button in the group may be checked and so this method can be only called with `value`  set to ``True``. To uncheck a radio button in a group you must check another button in the same group. 




      :param `value`: ``True`` to check, ``False`` to uncheck.   
      :type `value`: bool




                  





   .. attribute:: Value
