Overview

Tablelist supports interactive cell editing with the aid of the Tk core entry, spinbox, and checkbutton widgets.  These widgets are automatically registered for cell editing, hence the only action needed for using one of them for editing the cells of a given column is as follows:

Use the tablelist widget's columnconfigure subcommand to set the given column's -editable option to true and its -editwindow option to entry, spinbox, or checkbutton, respectively.  (These options are supported at cell level, too, with the aid of the cellconfigure subcommand.)  Since the default value of the -editwindow column configuration option is entry, it is not necessary to set it explicitly if the editing should take place with the aid of an embedded entry widget.

Interactive Cell Editing Using the entry Widget

DESCRIPTION
As mentioned above, the interactive cell editing in a tablelist widget takes place per default with the aid of an embedded entry widget.  Refer to the INTERACTIVE CELL EDITING section of the reference page describing the tablelist::tablelist command for details on the editing process.

Interactive Cell Editing Using the spinbox Widget

DESCRIPTION
The temporary embedded spinbox widget used for interactive cell editing will be created with its -state option set to normal, which makes the widget editable.  You can use the script corresponding to the -editstartcommand tablelist configuration option to set the state of the spinbox to readonly or define validations for it, as well as for setting its (range of) values and its -wrap option.

Interactive Cell Editing Using the checkbutton Widget.

DESCRIPTION
On Windows, Mac OS Classic, and Mac OS X Aqua the temporary embedded checkbutton widget used for interactive cell editing will be created with explicitly set values for its -borderwidth, -padx, -pady, and -variable options.  In an X11 environment it will be created with explicitly set values for its -borderwidth, -indicatoron, -image, -selectimage, -selectcolor, and -variable options.  You can use the script corresponding to the -editstartcommand tablelist configuration option to set any other configuration options, like -offvalue and -onvalue, according to the internal values of the cells.  Since the default values of the -offvalue and -onvalue checkbutton options are 0 and 1, you don't need to change these options if the cells have the same internal values 0 and 1.
