#
# o listctrl mixin needs wx renamer.

# 
# 12/14/2003 - Jeff Grimmett (grimmtooth@softhome.net)
#
# o ColumnSorterMixin implementation was broke - added event.Skip()
#   to column click event to allow event to fall through to mixin.

overview = """\
<html>
<body>
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 (but not for virtual list controls), the items are stored 
in the control and must be added to it using InsertItem method.

<p>To intercept events from a list control, use the event table macros described in 
<code>wxListEvent.</code>

<h3>Mix-ins</h3>
This example demonstrates how to use mixins. The following mixins are available.

<h4>ColumnSorterMixin</h4>

<code><b>ColumnSorterMixin(numColumns)</b></code>

<p>A mixin class that handles sorting of a wxListCtrl in REPORT mode when the column 
header is clicked on.

<p>There are a few requirments needed in order for this to work genericly:
<p><ol>
    <li>The combined class must have a <code>GetListCtrl</code> method that returns 
    the ListCtrl to be sorted, and the list control must exist at the time the 
    <code>ColumnSorterMixin.__init__()</code>method is called because it uses 
    <code>GetListCtrl</code>.

    <li>Items in the list control must have a unique data value set with 
    <code>list.SetItemData</code>.

    <li>The combined class must have an attribute named <code>itemDataMap</code>
    that is a dictionary mapping the data values to a sequence of objects 
    representing the values in each column.  These valuesare compared in 
    the column sorter to determine sort order.
</ol>

<p>Interesting methods to override are <code>GetColumnSorter</code>,
<code>GetSecondarySortValues</code>, and <code>GetSortImages</code>.

<h5>Methods</h5>
<dl>
<dt><code>SetColumnCount(newNumColumns)</code>
<dd>Informs the mixin as to the number of columns in the control. When it is
set, it also sets up an event handler for <code>EVT_LIST_COL_CLICK</code> events.

<dt><code>SortListItems(col=-1, ascending=1)</code>
<dd>Sort the list on demand.  Can also be used to set the sort column and order.

<dt><code>GetColumnWidths()</code>
<dd>Returns a list of column widths.  Can be used to help restore the current 
view later.

<dt><code>GetSortImages()</code>
<dd>Returns a tuple of image list indexes the indexes in the image list for an 
image to be put on the column header when sorting in descending order

<dt><code>GetColumnSorter()</code>
<dd>Returns a callable object to be used for comparing column values when sorting.

<dt><code>GetSecondarySortValues(col, key1, key2)</code>
<dd>Returns a tuple of 2 values to use for secondary sort values when the
items in the selected column match equal.  The default just returns the 
item data values.

</dl>

<h4>ListCtrlAutoWidthMixin</h4>

<code><b>ListCtrlAutoWidthMixin()</b></code>

<p>A mix-in class that automatically resizes the last column to take up the 
remaining width of the ListCtrl.

<p>This causes the ListCtrl to automatically take up the full width of the list, 
without either a horizontal scroll bar (unless absolutely necessary) or empty 
space to the right of the last column.

<p><b>NOTE:</b> This only works for report-style lists.

<p><b>WARNING:</b> If you override the <code>EVT_SIZE</code> event in your ListCtrl, 
make sure you call event.Skip() to ensure that the mixin's _OnResize method is 
called.

<p>This mix-in class was written by <a href='mailto:ewestra@wave.co.nz'>Erik Westra </a>

<h5>Methods</h5>
<dl>

<dt><code>resizeLastColumn(minWidth)</code>
<dd>Resize the last column appropriately. If the list's columns are too wide to 
fit within the window, we use a horizontal scrollbar.  Otherwise, we expand the 
right-most column to take up the remaining free space in the list. This method is 
called automatically when the ListCtrl is resized; you can also call it yourself 
whenever you want the last column to be resized appropriately (eg, when adding, 
removing or resizing columns).  'minWidth' is the preferred minimum width for 
the last column.

</dl>


<h4>ListCtrlSelectionManagerMix</h4>

<code><b>ListCtrlSelectionManagerMix()</b></code>

<p>Mixin that defines a platform independent selection policy

<p>As selection single and multi-select list return the item index or a 
list of item indexes respectively.

<h5>Methods</h5>
<dl>

<dt><code>getPopupMenu()</code>
<dd>Override to implement dynamic menus (create)

<dt><code>setPopupMenu(menu)</code>
<dd>Must be set for default behaviour.

<dt><code>afterPopupMenu()</code>
<dd>Override to implement dynamic menus (destroy).

<dt><code>getSelection()</code>
<dd>Returns the current selection (or selections  as a Python list if extended 
selection is enabled)
