"""IDLE Configuration Dialog: support user customization of IDLE by GUI
Customize font faces, sizes, and colorization attributes. Set indentation
defaults. Customize keybindings. Colorization and keybindings can be
saved as user defined sets. Select startup options including shell/editor
and default window size. Define additional help sources.
Note that tab width in IDLE is currently fixed at eight due to Tk issues.
Refer to comments in EditorWindow autoindent code for details.

"""Return frame of widgets for General tab.
Enable users to provisionally change general options. Function
load_general_cfg intializes tk variables and helplist using
idleConf. Radiobuttons startup_shell_on and startup_editor_on
set var startup_edit. Radiobuttons save_ask_on and save_auto_on
set var autosave. Entry boxes win_width_int and win_height_int
set var win_width and win_height. Setting var_name invokes the
var_changed_var_name callback that adds option to changes.
Helplist: load_general_cfg loads list user_helplist with
name, position pairs and copies names to listbox helplist.
Clicking a name invokes help_source selected. Clicking
button_helplist_name invokes helplist_item_name, which also
changes user_helplist. These functions all call
set_add_delete_state. All but load call update_help_changes to
rewrite changes['main']['HelpFiles'].
