[Tkinter] tkinter.Menu – How to make text-variable?

[deanhystad]

The best documentation for tkinter may be to look at the underlying tk commands.

https://www.tcl.tk/man/tcl8.6/TkCmd/contents.htm

For example, the tk documentation has this to say about label.

Command-Line Name: -textvariable
Database Name: textVariable
Database Class: Variable
Specifies the name of a global variable. The value of the variable is a text string to be displayed inside the widget; if the variable value changes then the widget will automatically update itself to reflect the new value. The way in which the string is displayed in the widget depends on the particular widget and may be determined by other options, such as -anchor or -justify.

Looking under menu I only find 1 variable.

-variable value
Available only for checkbutton and radiobutton entries. Specifies the name of a global variable to set when the entry is selected. For checkbutton entries the variable is also set when the entry is deselected. For radiobutton entries, changing the variable causes the currently-selected entry to deselect itself.
For checkbutton entries, the default value of this option is taken from the -label option, and for radiobutton entries a single fixed value is used. It is recommended that you always set the -variable option when creating either a checkbutton or a radiobutton.
