 There is some Ltk documentation on the Ltk webpage (actually it even
mentions the answer to your question...) but I have to agree that I
could spend more time on it eventually.
In general, all widgets where it is appropriate, either have the
(settable) accessor "text" or "value", so for entries you can just
read/set it with (text entry) assuming entry is your widget instance.
All the widgets which inherit from tktextvariable have the text
accessor, those who inherit from the tkvariable class have the value
accessor.
