focusIn

[Kay C Lan]

LC 7.0.3
New stack, two new fields with their lockText set to true.
In both fields their scripts:

on focusIn
   set the backgroundColor of me to green
end focusIn

on focusOut
   set the backgroundColor of me to red
end focusOut

Pressing the Tab key moves the focus from one to the other and the
backgroundColor changes from green to red and vice versa.
If I change the lockText to false in both fields, then change the script to:

on openField
   set the backgroundColor of me to green
end openField

on ExitField
   set the backgroundColor of me to red
end ExitField

Again the backgroundColor changes from red to green and vice versa when I
tab.

So you are right. There is no difference.

PS If you need the same to happen when data in the field is changed then
you'd also have to include an CloseField handler.
