(KevinWalzer): TableListTileWrapper is a Tkinter version of the TableList widget, developed by Csaba Nemethi (http://www.nemethi.de), with support for the Tile theming extension (http://tktable.sourceforge.net/tile). TableList itself is a powerful, pure-Tcl multi-column listbox (see http://wiki.tcl.tk/5527) with a variety of configuration options. It was first wrapped for Tkinter by (?MartinFranklin) and subsequently adapted for Tile theming by me. The original version of Martin Franklin's work has disappeared from the Internet, so I am posting this version for others to make use of. Note: Tablelist is a pure-Tcl extension and Tile itself is a binary Tk extension that must installed in the appropriate location for Tk libraries on your system. This wrapper will not work without the corresponding Tcl/Tk libraries installed. See TableListWrapper for a version that does not support platform-specific theming but instead uses the traditional Tk widgets.
###November 2006: Posted by Kevin Walzer, kw@codebykevin.com. Based on Tablelist wrapper by Martin Franklin.
###Freely reusable.
###December 2007: Minor update to add keyboard navigation/TablelistSelect virtual event to demo.

class TableList(Widget):
'''A tablelist widget is a multi-column listbox.
The width of each column can be dynamic (i.e., just large enough to hold all its elements,
including the header) or static (specified in characters or pixels). The columns are, per
default, resizable. The alignment of each column can be specified as left, right, or center.
The columns, rows, and cells can be configured individually. Several of the global and
column-specific options refer to the headers, implemented as label widgets. For instance,
the -labelcommand option specifies a Tcl command to be invoked when mouse button 1 is released over
a label. The most common value of this option is tablelist::sortByColumn, which sorts the items
based on the respective column.
Interactive editing of the elements of a tablelist widget can be enabled for individual cells and
for entire columns. A great variety of widgets from the Tk core and from the packages BWidget,
Iwidgets, combobox, and Mentry is supported for being used as embedded edit window. In addition,
a rich set of keyboard bindings is provided for a comfortable navigation between the editable cells.
The Tcl command corresponding to a tablelist widget is very similar to the one associated with a
normal listbox. There are column-, row-, and cell-specific counterparts of the configure and cget
subcommands (columnconfigure, rowconfigure, cellconfigure, ...). They can be used, among others,
to insert images into the cells and the header labels, or to insert embedded windows into the cells.
The index, nearest, and see command options refer to the rows, but similar subcommands are provided
for the columns and cells (columnindex, cellindex, ...). The items can be sorted with the sort and
sortbycolumn command options.
The bindings defined for the body of a tablelist widget make it behave just like a normal listbox.
This includes the support for the virtual event <<ListboxSelect>>
(which is equivalent to <<TablelistSelect>>). In addition, version 2.3 or higher of the widget
callback package Wcb (written in pure Tcl/Tk code as well) can be used to define callbacks for the
activate, selection set, and selection clear commands, and Wcb version 3.0 or higher also
supports callbacks for the activatecell, cellselection set, and cellselection clear commands.

option may have any of the following
CELL CONFIGURATION OPTIONS
The following options are currently supported by the cellcget
and cellconfigure commands:
-background color or -bg color
Specifies the normal background color to use when displaying
the contents of the cell.
-editable boolean
Specifies whether the contents of the cell can be edited
interactively. The default value is 0. This option
overrides the one with the same name for the column
containing the given cell.
-font font
Specifies the font to use when displaying the contents
of the cell.
-foreground color or -fg color
Specifies the normal foreground color to use when
displaying the contents of the cell.
-image image
Specifies the name of the Tk image to be displayed in the
cell. image must be the result of an invocation of the
image create command, or an empty string, specifying that
no image is to be displayed. If the column containing the
cell is right-aligned then the image will be displayed to
the right of the cell"s text, otherwise to its left. The
text and the image are separated from each other by a
space character. If for the same cell the -window option
was specified with a nonempty value then it overrides the
-image option. If the tablelist"s state is disabled then
this option will be ignored.
To display an image in a cell, Tablelist makes use of an
embedded label widget. This requires more memory than
inserting the image directly into the tablelist"s body, but
has the main advantage of making it possible to adjust the
width of the label containing the widget to fit into its
column. This has the visual effect of cutting off part of
the image from its right or left side, depending on the
column"s alignment. M; To make sure that images with
transparent background will be dispklayed correctly, the
background color of the label widgets containing the
embedded images is automatically updated whenever necessary.
-selectbackground color
Specifies the background color to use when displaying the
contents of the cell while it is selected.
-selectforeground color
Specifies the foreground color to use when displaying the
contents of the cell while it is selected.
-text text
Specifies the string to be displayed in the given cell,
i.e., updates the element contained in the cell. If the
tablelist"s state is disabled then this option will be
ignored.
-window command
Specifies a Tcl command creating the window to be embedded
into the cell. The command is automatically concatenated
with the name of the tablelist widget, the cell"s row and
column indices, as well as the path name of the embedded
window to be created, and the resulting script is evaluated
in the global scope. command may also be an empty string,
specifying that no embedded window is to be displayed. If
the column containing the cell is right-aligned then the
window will be displayed to the right of the cell"s text,
otherwise to its left. The text and the window are
separated from each other by a space character. If this
option was specified with a nonempty value then it
overrides the -image cell configuration option. If the
tablelist"s state is disabled then this option will be
ignored.
There are several situations where the embedded window will
be destroyed and later recreated by invoking the script
mentioned above. For example, when changing the value of
some of the tablelist widget or column configuration
options, sorting the items, or moving a row or a column,
the widget"s contents will be redisplayed, which makes it
necessary to recreate the embedded windows. This operation
won"t preserve the changes made on the embedded windows
after their creation. For this reason, you should avoid
any changes on embedded windows outside their creation
scripts.
The -background, -font, -foreground, -selectbackground, and
-selectforeground cell configuration options override the
options with the same names set at row, column, or widget level
if the specified value is not an empty string.
See the COLORS AND FONTS section for further details on these options.
