When a TextEdit view is has its isNumeric Aspect set to true, and you
attempt to type in non-numeric characters, you get a popup-helper which says
"Unacceptable Character You can only type a number here."
Where is that implemented? I can't seem to find it anywhere... If I halt in
TextEdit>>wmKeyDown:wParam:lParam: the popup still appears... Seems tricky,
but I'm sure it's not, and I'm just missing the obvious
I'm asking for multiple reasons:
a) I'd like to understand it
b) I'd like to change it
Anyone attempted this?
