.. _wx.ListCtrl:

==========================================================================================================================================
|phoenix_title|  **wx.ListCtrl**
==========================================================================================================================================

A list control presents lists in a number of formats: list view, report view, icon view and small icon view.          

In any case, elements are numbered from zero. For all these modes, the items are stored in the control and must be added to it using :meth:`wx.ListCtrl.InsertItem`   method. 

A special case of report view quite different from the other modes of the list control is a virtual control in which the items data (including text, images and attributes) is managed by the main program and is requested by the control itself only when needed which allows having controls with millions of items without consuming much memory. To use virtual list control you must use :meth:`wx.ListCtrl.SetItemCount`   first and override at least :meth:`wx.ListCtrl.OnGetItemText`   (and optionally :meth:`wx.ListCtrl.OnGetItemImage`   or :meth:`wx.ListCtrl.OnGetItemColumnImage`   and :meth:`wx.ListCtrl.OnGetItemAttr` ) to return the information about the items when the control requests it. 

Virtual list control can be used as a normal one except that no operations which can take time proportional to the number of items in the control happen –  this is required to allow having a practically infinite number of items. For example, in a multiple selection virtual list control, the selections won't be sent when many items are selected at once because this could mean iterating over all the items. 

Using many of :ref:`wx.ListCtrl`  features is shown in the :ref:`corresponding sample <corresponding sample>`. 

To intercept events from a list control, use the event table macros described in :ref:`wx.ListEvent`. 

**Mac Note**: Starting with wxWidgets 2.8, :ref:`wx.ListCtrl`  uses a native implementation for report mode, and uses a generic implementation for other modes. You can use the generic implementation for report mode as well by setting the  ``mac.listctrl.always_use_generic``   system option (see  :ref:`wx.SystemOptions`) to 1. 





.. _ListCtrl-styles:

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

This class supports the following styles: 

  

- ``wx.LC_LIST``: Multicolumn list view, with optional small icons. Columns are computed automatically, i.e. you don't set columns as in  ``LC_REPORT`` . In other words, the list wraps, unlike a  :ref:`wx.ListBox`.  
- ``wx.LC_REPORT``: Single or multicolumn report view, with optional header.  
- ``wx.LC_VIRTUAL``: The application provides items text on demand. May only be used with  ``LC_REPORT`` .   
- ``wx.LC_ICON``: Large icon view, with optional labels.  
- ``wx.LC_SMALL_ICON``: Small icon view, with optional labels.  
- ``wx.LC_ALIGN_TOP``: Icons align to the top. Win32 default, Win32 only.  
- ``wx.LC_ALIGN_LEFT``: Icons align to the left.  
- ``wx.LC_AUTOARRANGE``: Icons arrange themselves. Win32 only.  
- ``wx.LC_EDIT_LABELS``: Labels are editable: the application will be notified when editing starts.  
- ``wx.LC_NO_HEADER``: No header in report mode.  
- ``wx.LC_SINGLE_SEL``: Single selection (default is multiple).  
- ``wx.LC_SORT_ASCENDING``: Sort in ascending order. (You must still supply a comparison callback in :meth:`wx.ListCtrl.SortItems` .)  
- ``wx.LC_SORT_DESCENDING``: Sort in descending order. (You must still supply a comparison callback in :meth:`wx.ListCtrl.SortItems` .)  
- ``wx.LC_HRULES``: Draws light horizontal rules between rows in report mode.  
- ``wx.LC_VRULES``: Draws light vertical rules between columns in report mode.

.. note:: 

   Under wxMSW this control uses :ref:`SystemThemedControl`  for an explorer style appearance by default since wxWidgets 3.1.0. If this is not desired, you can call :meth:`SystemThemedControl.EnableSystemTheme`   with  ``false``   argument to disable this.

                style=LC_ICON, validator=DefaultValidator, name=ListCtrlNameStr)
       
   
   A list control presents lists in a number of formats: list view,
   report view, icon view and small icon view.

   .. method:: Append(self, entry)

      Append an item to the list control.  The `entry` parameter should be a
      sequence with an item for each column



   .. method:: AppendColumn(self, heading, format=LIST_FORMAT_LEFT, width=-1)

      Adds a new column to the list control in report view mode.                  

      This is just a convenient wrapper for :meth:`InsertColumn`   which adds the new column after all the existing ones without having to specify its position explicitly. 

                


      :param `heading`: 
      :type `heading`: string
      :param `format`:

   .. method:: Arrange(self, flag=LIST_ALIGN_DEFAULT)

      Arranges the items in icon or small icon view.                  

      This only has effect on Win32. `flag`  is one of:

      - ``wx.LIST_ALIGN_DEFAULT``: Default alignment. 
      - ``wx.LIST_ALIGN_LEFT``: Align to the left side of the control.

      :type `flag`: int




      :rtype: `bool`








   .. method:: AssignImageList(self, imageList, which)

      Sets the image list associated with the control and takes ownership of it (i.e.                  

      the control will, unlike when using :meth:`SetImageList` , delete the list when destroyed). `which`  is one of  ``IMAGE_LIST_NORMAL`` ,   ``IMAGE_LIST_SMALL`` ,   ``IMAGE_LIST_STATE``   (the last is unimplemented). 

                


      :param `imageList`: 
      :type `imageList`: wx.ImageList
      :param `which`: 
      :type `which`: int






      .. seealso:: :meth:`SetImageList`     








   .. method:: CheckItem(self, item, check=True)

      Check or uncheck a :ref:`wx.ListItem`  in a control using checkboxes.                  

      This method only works if checkboxes support had been successfully enabled using :meth:`EnableCheckBoxes` . 




      :param `item`: Item (zero-based) index.   
      :type `item`: long
      :param `check`: If ``True``, check the item, otherwise uncheck.

      .. versionadded:: 4.1/wxWidgets-3.1.0  
     








   .. method:: ClearAll(self)

      Deletes all items and all columns.                  

                 



      .. note:: 

         This sends an event of type  ``wxEVT_LIST_DELETE_ALL_ITEMS``   under all platforms.    








   .. method:: ClearColumnImage(self, col)




   .. method:: Create(self, parent, id=ID_ANY, pos=DefaultPosition, size=DefaultSize, style=LC_ICON, validator=DefaultValidator, name=ListCtrlNameStr)

      Creates the list control.                  

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

   .. method:: DeleteAllColumns(self)

      Delete all columns in the list control.                  

                

      :rtype: `bool`







      :returns: 

         ``True`` if all columns were successfully deleted, ``False`` otherwise.   








   .. method:: DeleteAllItems(self)

      Deletes all items in the list control.                  

      This function does `not`  send the  ``wxEVT_LIST_DELETE_ITEM``   event because deleting many items from the control would be too slow then (unlike  :meth:`wx.ListCtrl.DeleteItem` ) but it does send the special  ``wxEVT_LIST_DELETE_ALL_ITEMS``   event if the control was not empty. If it was already empty, nothing is done and no event is sent. 

                

      :rtype: `bool`







      :returns: 

         ``True`` if the items were successfully deleted or if the control was already empty, ``False`` if an error occurred while deleting the items.   








   .. method:: DeleteColumn(self, col)

      Deletes a column.                  


      :param `col`: 
      :type `col`: int




      :rtype: `bool`








   .. method:: DeleteItem(self, item)

      Deletes the specified item.                  

      This function sends the  ``wxEVT_LIST_DELETE_ITEM``   event for the item being deleted. 

                


      :param `item`: 
      :type `item`: long




      :rtype: `bool`







      .. seealso:: :meth:`DeleteAllItems`     








   .. method:: EditLabel(self, item)

      Starts editing the label of the given item.                  

      This function generates a  ``EVT_LIST_BEGIN_LABEL_EDIT``   event which can be vetoed so that no text control will appear for in-place editing. 

      If the user changed the label (i.e. s/he does not press ``ESC`` or leave the text control without changes, a  ``EVT_LIST_END_LABEL_EDIT``   event will be sent which can be vetoed as well.                   


      :param `item`: 
      :type `item`: long




      :rtype: :ref:`wx.TextCtrl`








   .. method:: EnableAlternateRowColours(self, enable=True)

      Enable alternating row background colours (also called zebra striping).                  

      This method can only be called for the control in virtual report mode, i.e. having ``LC_REPORT``  and ``LC_VIRTUAL``  styles. 

      When enabling alternating colours, the appropriate colour for the even rows is chosen automatically depending on the default foreground and background colours which are used for the odd rows. 




      :param `enable`: If ``True``, enable alternating row background colours, i.e. different colours for the odd and even rows. If ``False``, disable this feature and use the same background colour for all rows.  
      :type `enable`: bool




                  



      .. versionadded:: 2.9.5 
    







      .. seealso:: :meth:`SetAlternateRowColour`     








   .. method:: EnableBellOnNoMatch(self, on=True)

      Enable or disable a beep if there is no match for the currently entered text when searching for the item from keyboard.                  

      The default is to not beep in this case except in wxMSW where the beep is always generated by the native control and cannot be disabled, i.e. calls to this function do nothing there. 

                


      :param `on`: 
      :type `on`: bool






      .. versionadded:: 2.9.5 
     








   .. method:: EnableCheckBoxes(self, enable=True)

      Enable or disable checkboxes for list items.                  




      :param `enable`: If ``True``, enable checkboxes, otherwise disable checkboxes.   
      :type `enable`: bool






      :rtype: `bool`




      In a list control with ``wx.LC_VIRTUAL`` style you have to keep track of the checkbox state. When a checkbox is clicked (``EVT_LIST_ITEM_CHECKED`` or ``EVT_LIST_ITEM_UNCHECKED``) you have to update the state and refresh the item yourself.  

                 



      :returns: 

         ``True`` if checkboxes are supported, ``False`` otherwise.  







      .. versionadded:: 4.1/wxWidgets-3.1.0  
     







      .. seealso:: :meth:`OnGetItemIsChecked`   :meth:`RefreshItem`   








   .. method:: EnableSystemTheme(self, enable=True)

      Can be used to disable the system theme of controls using it by default. 

      On Windows there an alternative theme available for the list and list-like
      controls since Windows Vista. This theme is used by Windows Explorer list
      and tree view and so is arguably more familiar to the users than the standard
      appearance of these controls. This class automatically uses the new theme,
      but if that is not desired then this method can be used to turn it off.

      Please note that this method should be called before the widget is
      actually created, using the 2-phase create pattern. Something like this::

              # This creates the object, but not the window
              widget = wx.ListCtrl()

              # Disable the system theme
              widget.EnableSystemTheme(False)

              # Now create the window
              widget.Create(parent, wx.``wx.ID_ANY``)

      This method has no effect on other platorms 


      :param `enable`: 
      :type `enable`: bool







   .. method:: EnsureVisible(self, item)

      Ensures this item is visible.                  


      :param `item`: 
      :type `item`: long




      :rtype: `bool`








   .. method:: ExtendRulesAndAlternateColour(self, extend=True)

      Extend rules and alternate rows background to the entire client area.                  

      Bu default, the rules (when enabled with ``wx.LC_HRULES`` and ``wx.LC_VRULES``) and alternate row background (when :meth:`EnableAlternateRowColours`   was called) are only shown in the part of the control occupied by the items, which can be smaller than the entire window if there are few items in the control. 

      Calling this function extends the display of the rules and alternate background rows to the entire client area. 

      Similarly to :meth:`EnableAlternateRowColours` , this method can only be used with controls having ``LC_REPORT``  and ``LC_VIRTUAL``  styles. 

      Note that this method is currently not implemented in the native MSW version and does nothing there. 




      :param `extend`: if ``True``, draws horizontal rules and vertical rules on empty rows and uses the colour parameter to paint the background of alternate rows when those rows are blank, empty, with no data.  
      :type `extend`: bool

      Returns the colour for this item.                  

      If the item has no specific colour, returns an invalid colour (and not the default foreground control of the control itself as this wouldn't allow distinguishing between items having the same colour as the current control foreground and items with default colour which, hence, have always the same colour as the control).

      Searches for an item with the given geometry or state, starting from `item`  but excluding the `item`  itself.                  

      If `item`  is -1, the first item that matches the specified flags will be returned. Returns the first item with given state following `item`  or -1 if no such item found. This function may be used to find all selected items in the control like this: 

      ::

                  item = -1

                  while 1:
                      item = listctrl.GetNextItem(item,
                                                  wx.LIST_NEXT_ALL,

                      if item == -1:
                          break

                      # This item is selected - do whatever is needed with it
                      wx.LogMessage("Item %ld is selected"%item)



      `geometry`  can be one of:

      - ``wx.LIST_NEXT_ABOVE``: Searches for an item above the specified item. 
      - ``wx.LIST_NEXT_ALL``: Searches for subsequent item by index. 
      - ``wx.LIST_NEXT_BELOW``: Searches for an item below the specified item. 
      - ``wx.LIST_NEXT_LEFT``: Searches for an item to the left of the specified item. 
      - ``wx.LIST_NEXT_RIGHT``: Searches for an item to the right of the specified item. 




      `state`  can be a bitlist of the following:

      - ``wx.LIST_STATE_DONTCARE``: Don't care what the state is. 
      - ``wx.LIST_STATE_DROPHILITED``: The item indicates it is a drop target. 
      - ``wx.LIST_STATE_FOCUSED``: The item has the focus. 
      - ``wx.LIST_STATE_SELECTED``: The item is selected. 
      - ``wx.LIST_STATE_CUT``: The item is selected as part of a cut and paste operation.

      .. note:: 

         this parameter is only supported by wxMSW currently and ignored on other platforms.  








   .. method:: GetNextSelected(self, item)

      Returns subsequent selected items, or -1 when no more are selected.



   .. method:: GetSelectedItemCount(self)

      Returns the number of selected items in the list control.                  

      :rtype: `int`








   .. method:: GetSubItemRect(self, item, subItem, rect, code=LIST_RECT_BOUNDS)

      Returns the rectangle representing the size and position, in physical coordinates, of the given subitem, i.e.                  

      the part of the row `item`  in the column `subItem`. 

      This method is only meaningful when the :ref:`wx.ListCtrl`  is in the report mode. If `subItem`  parameter is equal to the special value  ``LIST_GETSUBITEMRECT_WHOLEITEM``   the return value is the same as for  :meth:`GetItemRect` . 

      `code`  can be one of  ``LIST_RECT_BOUNDS`` ,   ``LIST_RECT_ICON``   or   ``LIST_RECT_LABEL`` . 

      Note that using  ``LIST_RECT_ICON``   with any sub-item but the first one isn't very useful as only the first sub-item can have an icon in  :ref:`wx.ListCtrl`. In this case, i.e. for  ``subItem``   > 0, this function simply returns an empty rectangle in  `rect`. 

                


      :param `item`: 
      :type `item`: long
      :param `subItem`:

      :rtype: `long`








   .. method:: GetViewRect(self)

      Returns the rectangle taken by all items in the control.                  

      In other words, if the controls client size were equal to the size of this rectangle, no scrollbars would be needed and no free space would be left. 

      Note that this function only works in the icon and small icon views, not in list or report views (this is a limitation of the native Win32 control).                  

      :rtype: :ref:`wx.Rect`








   .. method:: HasCheckBoxes(self)

      Determines which item (if any) is at the specified point, giving details in `flags`.                  

      Returns index of the item or  ``NOT_FOUND``   if no item is at the specified point. 

      `flags`  will be a combination of the following flags:

      - ``wx.LIST_HITTEST_ABOVE``: Above the control's client area. 
      - ``wx.LIST_HITTEST_BELOW``: Below the control's client area. 
      - ``wx.LIST_HITTEST_TOLEFT``: To the left of the control's client area. 
      - ``wx.LIST_HITTEST_TORIGHT``: To the right of the control's client area. 
      - ``wx.LIST_HITTEST_NOWHERE``: Inside the control's client area but not over an item. 
      - ``wx.LIST_HITTEST_ONITEMICON``: Over an item's icon. 
      - ``wx.LIST_HITTEST_ONITEMLABEL``: Over an item's text. 
      - ``wx.LIST_HITTEST_ONITEMSTATEICON``: Over the checkbox of an item. 
      - ``wx.LIST_HITTEST_ONITEM``: Combination of  ``LIST_HITTEST_ONITEMICON`` ,   ``LIST_HITTEST_ONITEMLABEL`` ,   ``LIST_HITTEST_ONITEMSTATEICON`` . 




      If `ptrSubItem`  is not ``None`` and the :ref:`wx.ListCtrl`  is in the report mode the subitem (or column) number will also be provided. This feature is only available in version 2.7.0 or higher and is currently only implemented under wxMSW and requires at least comctl32.dll of version 4.70 on the host system or the value stored in `ptrSubItem`  will be always -1. To compile this feature into wxWidgets library you need to have access to commctrl.h of version 4.70 that is provided by Microsoft.

      It should return the attribute for the specified  ``item``   or ``None`` to use the default appearance parameters. 

      :ref:`wx.ListCtrl`  will not delete the pointer or keep a reference of it. You can return the same :ref:`wx.ItemAttr`  pointer for every :meth:`OnGetItemAttr`   call.

      It should return the index of the items image in the controls image list or -1 for no image. 

      In a control with  ``LC_REPORT``   style,  :meth:`OnGetItemImage`   only gets called for the first column of each line.

   .. method:: SetAlternateRowColour(self, colour)

      Set the alternative row background colour to a specific colour.                  

      It is recommended to call :meth:`EnableAlternateRowColours`   instead of using these methods as native implementations of this control might support alternating row colours but not setting the exact colour to be used for them. 

      As :meth:`EnableAlternateRowColours` , this method can only be used with controls having ``LC_REPORT``  and ``LC_VIRTUAL``  styles. 




      :param `colour`: A valid alternative row background colour to enable alternating rows or invalid colour to disable them and use the same colour for all rows.

   .. method:: SetColumnImage(self, col, image)




   .. method:: SetColumnWidth(self, col, width)

      Sets the column width.                  

      `width`  can be a width in pixels or  ``LIST_AUTOSIZE``   (-1) or   ``LIST_AUTOSIZE_USEHEADER``   (-2). 

       ``LIST_AUTOSIZE``   will resize the column to the length of its longest item. 

       ``LIST_AUTOSIZE_USEHEADER``   will resize the column to the length of the header (Win32) or 80 pixels (other platforms). 

      In small or normal icon view, `col`  must be -1, and the column width is set for all columns.                  


      :param `col`: 
      :type `col`: int
      :param `width`: 
      :type `width`: int




      :rtype: `bool`








   .. method:: SetColumnsOrder(self, orders)

      Changes the order in which the columns are shown.                  

      By default, the columns of a list control appear on the screen in order of their indices, i.e. the column 0 appears first, the column 1 next and so on. However by using this function it is possible to arbitrarily reorder the columns visual order and the user can also rearrange the columns interactively by dragging them. In this case, the index of the column is not the same as its order and the functions :meth:`GetColumnOrder`   and :meth:`GetColumnIndexFromOrder`   should be used to translate between them. Notice that all the other functions still work with the column indices, i.e. the visual positioning of the columns on screen doesn't affect the code setting or getting their values for example. 

      The `orders`  array must have the same number elements as the number of columns and contain each position exactly once. Its n-th element contains the index of the column to be shown in n-th position, so for a control with three columns passing an array with elements 2, 0 and 1 results in the third column being displayed first, the first one next and the second one last. 

      Example of using it: ::

                      listCtrl = wx.ListCtrl(parent, style=wx.LC_REPORT)

                      for i in range(3):
                          listCtrl.InsertColumn(i, "Column %d"%i)

                      order = [2, 0, 1]
                      listCtrl.SetColumnsOrder(order)

                      # now listCtrl.GetColumnsOrder() will return order and
                      # listCtrl.GetColumnIndexFromOrder(n) will return order[n] and
                      # listCtrl.GetColumnOrder() will return 1, 2 and 0 for the column 0,
                      # 1 and 2 respectively



      Please notice that this function makes sense for report view only and currently is only implemented in wxMSW port. To avoid explicit tests for  ``WXMSW``  in your code, please use   ``HAS_LISTCTRL_COLUMN_ORDER``   as this will allow it to start working under the other platforms when support for the column reordering is added there.

      :type `orders`: list of integers

   .. method:: SetHeaderAttr(self, attr)

      Change the font and the colours used for the list control header.                  

      This method can be used to change the appearance of the header shown by the control in report mode (unless  ``LC_NO_HEADER``   style is used). 

      Currently it is implemented only for wxMSW and does nothing in the other ports. 




      :param `attr`: The object containing the font and text and background colours to use. It may be default, i.e. not specify any custom font nor colours, to reset any previously set custom attribute.   
      :type `attr`: wx.ItemAttr






      :rtype: `bool`



                  



      :returns: 

         ``True`` if the attributes have been updated or ``False`` if this is not supported by the current platform.

   .. method:: SetImageList(self, imageList, which)

      Sets the image list associated with the control.                  

      `which`  is one of  ``IMAGE_LIST_NORMAL`` ,   ``IMAGE_LIST_SMALL`` ,   ``IMAGE_LIST_STATE``   (the last is unimplemented). 

      This method does not take ownership of the image list, you have to delete it yourself.

      This method can only be used with virtual list controls.                  

      It is used to indicate to the control the number of items it contains. After calling it, the main program should be ready to handle calls to various item callbacks (such as :meth:`wx.ListCtrl.OnGetItemText` ) for all items in the range from 0 to `count`. 

      Notice that the control is not necessarily redrawn after this call as it may be undesirable if an item which is not visible on the screen anyhow was added to or removed from a control displaying many items, if you do need to refresh the display you can just call :meth:`Refresh`   manually.

   .. method:: SetItemState(self, item, state, stateMask)

      Sets the item state.                  

      The `stateMask`  is a combination of  ``LIST_STATE_XXX``   constants described in  :ref:`wx.ListItem`  documentation. For each of the bits specified in `stateMask`, the corresponding state is set or cleared depending on whether `state`  argument contains the same bit or not. 

      So to select an item you can use ::

                      listCtrl.SetItemState(item, wx.LIST_STATE_SELECTED, wx.LIST_STATE_SELECTED)

      while to deselect it you should use ::

                      listCtrl.SetItemState(item, 0, wx.LIST_STATE_SELECTED)



      Consider using :ref:`wx.ListView`  if possible to avoid dealing with this error-prone and confusing method. 

      Also notice that contrary to the usual rule that only user actions generate events, this method does generate wxEVT_LIST_ITEM_SELECTED event when it is used to select an item.

   .. method:: SetItemText(self, item, text)

      Sets the item text for this item.                  


      :param `item`: 
      :type `item`: long
      :param `text`: 
      :type `text`: string







   .. method:: SetItemTextColour(self, item, col)

      Sets the colour for this item.                  

      This function only works in report view. The colour can be retrieved using :meth:`GetItemTextColour` .                  


      :param `item`: 
      :type `item`: long
      :param `col`: 
      :type `col`: wx.Colour







   .. method:: SetSingleStyle(self, style, add=True)

      Adds or removes a single window style.                  


      :param `style`: 
      :type `style`: long
      :param `add`: 
      :type `add`: bool







   .. method:: SetTextColour(self, col)

      Sets the text colour of the list control.                  


      :param `col`: 
      :type `col`: wx.Colour







   .. method:: SetWindowStyleFlag(self, style)

      Sets the whole window style, deleting all items.                  


      :param `style`: 
      :type `style`: long







   .. method:: SortItems(self, fnSortCallBack)

      Call this function to sort the items in the list control.                  

      Sorting is done using the specified `fnSortCallBack`  function. This function must have the following prototype: ::

                  def ListCompareFunction(self, item1, item2):

                      pass



      It is called each time when the two items must be compared and should return 0 if the items are equal, negative value if the first item is less than the second one and positive value if the first one is greater than the second one (the same convention as used by  ``qsort(3)`` ). 

      The parameter `item1`  is the client data associated with the first item (**NOT**  the index). The parameter `item2`  is the client data associated with the second item (**NOT**  the index). The parameter `data`  is the value passed to :meth:`SortItems`   itself. 

      Notice that the control may only be sorted on client data associated with the items, so you must use SetItemData if you want to be able to sort the items in the control. 

      Please see the :ref:`List Control Sample <list control sample>`  for an example of using this function.
