openField

openField

Handler:

on openField
   statements
end openField

HyperCard sends the openField message to an unlocked field when a user (or handler) first opens it for text editing. A user opens a field for editing either by clicking in the field or by tabbing from the previous field.

Once opened for editing, a field no longer receives openField messages.
