[SLUG] GUI standard question: Button label changes

[Rev Simon Rumble <simon@xxxxxxxxxx>]

Have a question to see if anyone knows what the standard behaviour
should be in a GUI application.  I've seen both out there.

You have a button.  The label on the button changes each time you
click it.  eg, let's say it changes a select list from [All] to
[Today].  Now the button could have two very different behaviours:

1) It shows the current state, ie when it says [All] that means all
   the items are displayed.
2) It shows what the button will do to the list, ie when is says [All]
   it means it is currently showing just Today and when you click the
   button it will display All.

So what is the standard?  Is there one?
