[Bug 44756] Calculator wont turn on "Thousands Separator".

[Martin Sondergaard]

Public bug reported:

The calculator, Gcalctool 5.6.31, has a minor bug.
The menu option "View, Show Thousands Separator", often doesn't work.  

Its a bug in toggling this option on and off.  As well as often failing
to turn this mode on, it also can fail to turn this mode off.  If I use
the keyboard shortcut, ^K, this also fails to work.

No, on second thoughts, perhaps its not a bug, it just looks like one.
It just doesn't behave the way I expected it to.  I've had a further
look at this, and now I'm not sure if its a bug, or just unexpected
behaviour.

If I enter a number, then select the option to Show Thousands Seperator,
it doesn't change how the existing number is displayed.  So I thought
that the "Show Thousands Separator" mode was not working.

But if I press the "=" key then it correctly shows commas in the number.

This may not count as a bug.  But I had difficulty turning on this mode,
because I saw that the existing number had not changed, (commas were not
added to it), so I thought it was not working.

I realise that when the user enters a number, the program can't add
commas yet, because it doesn't know the user had finished entering the
number until he presses "=" or some other operator key.

But when I selected the option to "Show Thousands Separator", I expected
the number currently being displayed by the calculator to change, at
once.  Perhaps it should be changed to do so.

Your comments are welcome on this.  Should the calculator have this
small change made to it?

** Affects: gcalctool (Ubuntu)
       Severity: Minor
