Subject: Re: Rookie question - mouseUp on unlocked field
I think making the field clear whenever the user clicks in it it is not
nice. If the user want to select some characters, the field clears. Maybe
you want to clear the field when the user clicks the first time (so a cursor
appears). Then the script would be:
on openField
put empty into field "Degrees C"
put empty into field "Degrees F"
end openField
A nice one would be:
on returnInField
send "mouseUp" to button "Convert"
end returnInField
on enterInField
send "mouseUp" to button "Convert"
end enterInField
So when the user presses return or enter, the convert starts.
BTW Do you know how to round numbers on a certain digits? If not, you can
use this:
set the numberFormat to "0.##"
