I have an idea that bbox does not give ‘exact’ answers.
When widgets are packed with ‘grid’, ->gridInfo() gives you information including thepositional data I am looking for.
I have tried ->windowInfo() but that gave an error.
Is there an equivalent for items placed on a canvas (or am I looking for something that does not exist)?
PS I have now implemented move to hide widgets on a canvas – it does just what I wanted.
