Thanks for all assistance in the past. Here’s one for y’all.
I am trying to create a text field that emulates the Start Time/Stop Time entry fields in iTunes track Get Info window (in the Options tab). So far, I am using an “end editing” handler to verify input text (only accept 0-9, “:”, and “.”) and handle conversion from minutes:seconds.100ths to seconds.100ths.
However, ideally, it would be nice to be able to disallow bad characters (anything but those I mentioned) as_they_are_being_typed.
Another problem is that unless “end editing” actually is invoked (when the text field loses focus), the text field will never be verified. I suppose I could come up with a workaround for this. Even so, “end editing” can only verify text after the entire new text is entered, which is not very neat.
Other than hitting a “changed” handler on each text input, is any routine pre-built anywhere that can deal with minutes:seconds.100ths in a text field?
DatePicker is probably out of the question, BTW.
Any thoughts most appreciated.
