Formatters in IB

[zots]

Does anyone know to creat a formatter? I want a formatter on a text field so that entries must be floats. I downloaded a source project from cocoadevcentral.com and when you click a textfield it has Formatter in the info pallete with Attributes, Connections, Size, etc.

You have to subclass NSFormatter, instantiate it, and then connect the text field's "formatter" attribute to it.

Then, to have it do your specific kind of formatting, I think you just have to override some of NSFormatter's methods.

Or you could just drag the Number formatter in the tools palette in Interface Builder directly onto the text field. Then, mess with the settings in the Info window.

I finally figured that out. I did not know those things were formatters. Thanks.
