Bryan Oakley's combobox package is a library extension for
Tcl/Tk version 8.0 or higher, written in pure Tcl/Tk code.
Its download location is
http://www.purl.org/net/oakley/tcl/combobox/index.html
Tablelist supports interactive cell editing with the aid of the
combobox widget implemented in the package mentioned above.
The steps needed for using this widget for editing the cells of a
given column are as follows:
- Register the combobox widget for interactive cell editing by
invoking the
tablelist::addOakleyCombobox command
described below.
- Use the tablelist widget's
columnconfigure
subcommand to set the given column's -editable option
to true and its -editwindow
option to the value returned by the command mentioned above.
(These options are supported at cell level, too, with the aid of
the cellconfigure
subcommand.)
The
tablelist::addOakleyCombobox Command
- NAME
tablelist::addOakleyCombobox - Register Bryan
Oakley's combobox widget for interactive cell editing
SYNOPSIS-
tablelist::addOakleyCombobox ?name?
- DESCRIPTION
- This command registers Bryan Oakley's combobox widget for
interactive cell editing in tablelist widgets. The optional
argument specifies the name to be used for the combobox widget as
the value of the
-editwindow
column or cell configuration option. It may be any string
that is different from entry,
text, spinbox,
checkbutton, ttk::entry,
ttk::checkbutton, and
ttk::combobox. The default is
combobox. The command returns its
name argument.
The temporary embedded combobox widget associated with the above
name will be created with its
-editable option set to 1.
You can use the script corresponding to the -editstartcommand
tablelist configuration option to make the combobox non-editable or
define validations for its entry child (whose path name can be
obtained by invoking the tablelist widget's entrypath
subcommand, or by appending .entry to the path
name of the combobox widget, or, if using combobox version 2.3 or
later, with the aid of the combobox widget's
subwidget entry subcommand), as well as
for populating its listbox component (by using the combobox
widget's list insert
subcommand).
