So, I've made a StringFormatter paletter for interface builder. It lets me use some Fortran formats because it's for formatting an input file to a Fortran program.

Anyways, it doesn't attach to text fields the way the built in NSNumberFormatter does, or like NSDateFormatter.

Does anyone have any idea of what I have to do to get it to attach to a text field?

Code:
@implementation StringFormatterPalette

- (void)finishInstantiate
{
	StringFormatter *formy;
	
	formy = [[StringFormatter alloc] initWithLength:30];
    [self associateObject:formy ofType:IBWindowPboardType withView:view];
}

@end

@implementation StringFormatter (StringFormatterPaletteInspector)

- (NSString *)inspectorClassName
{
    return @"StringFormatterInspector";
}

In the code, view is a custom view used for dragging, and is attached to my view in IB.

I am guessing that I need a special ofType thing, other that IBObjectPboardType. Any ideas? I would like the behavior to match the built in formatters in IB.

The answer was an easy one. I guess I was too tired to see it last night. I found it in IBPalette.h (part of the IB framework).

The required type is:
IBFormatterPboardType

The next question I have is, how would I go about detaching the NSFormatter from the NSTextField programatically so that I can implement the detach button?

Well.. just in case someone ever needs this, I found the answer to remove the formatter.

Code:
- (IBAction)detachFormatter:(id)sender
{
	TDStringFormatter *formatter;
	id                formattedObject;
	id   <IBDocuments> document;
	
	// get the required objects
	document = [NSApp activeDocument];
	formatter = [self object];
	formattedObject = [document parentOfObject:formatter];
	
	// detach the formatter
	[document detachObject:formatter];
	
	// make sure it's not referencing something that doesn't exist now
	[formattedObject setFormatter:nil];
	[document resetObject:formattedObject];
	
	// update the user interface, and mark the document as dirty
	[super ok:sender];
}

I got it from here.
