For 2021 - online Python 3 training - see ((here)).

Our plans were to retire in summer 2020 and see the world, but Coronavirus has lead us into a lot of lockdown programming in Python 3 and PHP 7.
We can now offer tailored online training - small groups, real tutors - works really well for groups of 4 to 14 delegates. Anywhere in the world; course language English.

Please ask about private 'maintenance' training for Python 2, Tcl, Perl, PHP, Lua, etc.
COMMAND ENTRIES in menus: enabling and disabling

Posted by Dimon (Dimon), 11 November 2005
The most common kind of menu-bar entry is a command entry. How to change the status of menu's Command entry from 'active' (or 'normal') to 'disabled'?

Posted by admin (Graham Ellis), 13 November 2005
Example ... for a menu named .menuname, you can disable entry number 6 by writing ....

.menuname  entryconfigure  6  -state  disabled

Thank you very much, Graham!
My mistake was the next: I tried to numbering menu items sequentially and mixed. I forgot about each cascade of menu is a separate menu with its own numbering
