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.##" Tim Barber wrote: Hi all I'm just fiddling around trying to learn how to use MC. I'm creating a simple temperature converter, and I've encountered a problem. My card consists of two fields (Degrees C and Degrees F), two labels(for the fields) and two buttons (Convert and Quit) If I understand the MetaTalk reference correctly (and it's more than likely I don't), an unlocked field doesn't receive mouseUp messages unless you hold down the ctrl key (I'm on a Mac). How then do I script the field to clear itself when I click in it? I've tried using a selectionChanged message handler, but it started acting weird. Here is the code I'm using. on selectionChanged #or mouseUp put empty into field "Degrees C" put empty into field "Degrees F" #I want it to clear both fields select field "Degrees C" end selectionChanged #or mouseUp My plan is that you click on either field and it clears both. You then enter whichever value you have (Centigrade or Fahrenheit) into the field, and click the Convert button. Depending on which field you entered, the Convert button calculates the result and populates the other.
