|phoenix_title|  **wx.ItemContainerImmutable**
==========================================================================================================================================

:ref:`wx.ItemContainer`  defines an interface which is implemented by all controls which have string subitems each of which may be selected.          

It is decomposed in :ref:`wx.ItemContainerImmutable`  which omits all methods adding/removing items and is used by :ref:`wx.RadioBox`  and :ref:`wx.ItemContainer`  itself. 

Note that this is not a control, it's a mixin interface that classes have to derive from in addition to :ref:`wx.Control`  or :ref:`wx.Window`. 

Examples: :ref:`wx.ListBox`, :ref:`wx.CheckListBox`, :ref:`wx.Choice`  and :ref:`wx.ComboBox`  (which implements an extended interface deriving from this one) 







         



.. seealso:: :ref:`wx.ControlWithItems`, :ref:`wx.ItemContainer`

:meth:`~wx.ItemContainerImmutable.__init__`                                      Constructor.
:meth:`~wx.ItemContainerImmutable.FindString`                                    Finds an item whose label matches the given string.
:meth:`~wx.ItemContainerImmutable.GetCount`                                      Returns the number of items in the control.
:meth:`~wx.ItemContainerImmutable.GetSelection`                                  Returns the index of the selected item or  ``NOT_FOUND``   if no item is selected.
:meth:`~wx.ItemContainerImmutable.GetString`                                     Returns the label of the item with the given index.
:meth:`~wx.ItemContainerImmutable.GetStringSelection`                            Returns the label of the selected item or an empty string if no item is selected.
:meth:`~wx.ItemContainerImmutable.GetStrings`                                    Returns the array of the labels of all items in the control.
:meth:`~wx.ItemContainerImmutable.IsEmpty`                                       Returns ``True`` if the control is empty or ``False`` if it has some items.
:meth:`~wx.ItemContainerImmutable.Select`                                        This is the same as :meth:`~ItemContainerImmutable.SetSelection`   and exists only because it is slightly more natural for controls which support multiple selection.
:meth:`~wx.ItemContainerImmutable.SetSelection`                                  Sets the selection to the given item `n`  or removes the selection entirely if `n`  ==  ``NOT_FOUND`` .
:meth:`~wx.ItemContainerImmutable.SetString`                                     Sets the label for the given item.
:meth:`~wx.ItemContainerImmutable.SetStringSelection`                            Selects the item with the specified string in the control.

.. class:: wx.ItemContainerImmutable(object)

   **Possible constructors**::

       ItemContainerImmutable()
       
   
   ItemContainer defines an interface which is implemented by all
   controls which have string subitems each of which may be selected.



   .. method:: __init__(self)

      Constructor.                   





   .. method:: FindString(self, string, caseSensitive=False)

      Finds an item whose label matches the given string.                  




      :param `string`: String to find.   
      :type `string`: string
      :param `caseSensitive`: Whether search is case sensitive (default is not).  
      :type `caseSensitive`: bool








      :rtype: `int`



                  



      :returns: 

         The zero-based position of the item, or ``wx.NOT_FOUND`` if the string was not found.   








   .. method:: GetCount(self)

      Returns the number of items in the control.                  

                

      :rtype: `int`







      .. seealso:: :meth:`IsEmpty`     








   .. method:: GetSelection(self)

      Returns the index of the selected item or  ``NOT_FOUND``   if no item is selected.                   

                

      :rtype: `int`







      :returns: 

         The position of the current selection.  







      .. note:: 

         This method can be used with single selection list boxes only, you should use :meth:`wx.ListBox.GetSelections`   for the list boxes with ``wx.LB_MULTIPLE`` style.  







      .. seealso:: :meth:`SetSelection` , :meth:`GetStringSelection`     








   .. method:: GetString(self, n)

      Returns the label of the item with the given index.                  




      :param `n`: The zero-based index.  
      :type `n`: int






      :rtype: `string`



                  



      :returns: 

         The label of the item or an empty string if the position was invalid.   








   .. method:: GetStringSelection(self)

      Returns the label of the selected item or an empty string if no item is selected.                  

                

      :rtype: `string`







      .. seealso:: :meth:`GetSelection`     








   .. method:: GetStrings(self)

      Returns the array of the labels of all items in the control.                  

      :rtype: `list of strings`








   .. method:: IsEmpty(self)

      Returns ``True`` if the control is empty or ``False`` if it has some items.                  

                

      :rtype: `bool`







      .. seealso:: :meth:`GetCount`     








   .. method:: Select(self, n)

      This is the same as :meth:`SetSelection`   and exists only because it is slightly more natural for controls which support multiple selection.                  


      :param `n`: 
      :type `n`: int







   .. method:: SetSelection(self, n)

      Sets the selection to the given item `n`  or removes the selection entirely if `n`  ==  ``NOT_FOUND`` .                   

      Note that this does not cause any command events to be emitted nor does it deselect any other items in the controls which support multiple selections. 




      :param `n`: The string position to select, starting from zero.  
      :type `n`: int




                  



      .. seealso:: :meth:`SetString` , :meth:`SetStringSelection`     








   .. method:: SetString(self, n, string)

      Sets the label for the given item.                  




      :param `n`: The zero-based item index.   
      :type `n`: int
      :param `string`: The label to set.   
      :type `string`: string






                  





   .. method:: SetStringSelection(self, string)

      Selects the item with the specified string in the control.                  

      This method doesn't cause any command events to be emitted. 

      Notice that this method is case-insensitive, i.e. the string is compared with all the elements of the control case-insensitively and the first matching entry is selected, even if it doesn't have exactly the same case as this string and there is an exact match afterwards. 




      :param `string`: The string to select.   
      :type `string`: string






      :rtype: `bool`



                  



      :returns: 

         ``True`` if the specified string has been selected, ``False`` if it wasn't found in the control.
