Hi,

I am wanting to create an editor that is capable of displaying breakpoints. It seems that NSRulerView and NSRulerMarker would work splendidly for this except for the fact that I can’t hide the measurement tick marks (unless I am missing something). Should I create a new subclass of NSView to handle this or am I making this more complicated than it needs to be?

Many Thanks! LauRence

try this:

// MyTextView.h

#import <AppKit/AppKit.h>

@interface MyTextView : NSScrollView { } @end

@interface MyRulerView : NSRulerView { } @end

// MyTextView.m

#import “UmTextView.h”

@implementation MyTextView

• (id)initWithFrame:(NSRect)frame { id textView, rulerView; self = [super initWithFrame:frame]; if (self) { rulerView = [[[MyRulerView alloc ] init ] autorelease ]; textView = [[[NSTextView alloc ] initWithFrame: frame ] autorelease ]; [self setDocumentView:textView ]; [self setRulersVisible:YES ]; [self setHasHorizontalRuler:YES ]; [self setBorderType:NSGrooveBorder ]; [self setHorizontalRulerView:rulerView ]; [self setDrawsBackground:YES ]; } return self; } @end

@implementation MyRulerView -(void)drawHashMarksAndLabelsInRect:(NSRect)rect { // the only purpose here is to override this method and do nothing } @end

Hope you don’t get confused when I call an NSScrollView MyTextView (this is what IB does, so I got into the habit of doing it). Interface Builder’s Text View is actually a scroll view with an NSTextView as the document view.

Not sure how far along you are with your program, so here’s a couple of ways you can use this custom object.

1. If you already have a scroll view with a ruler view, just replace the ruler view with MyRulerView.

2. If you want to use MyTextView as a custom view in IB do the following: *drag the object file (MyTextView.h) from PB to the MainMenu.nib in IB *drag and drop a Custom View object into a window. *select the Custom View by clicking on it *hit Command-1 to bring the info window to the front *select Custom Class from the drop down menu in the info window. *select MyTextView

now make the needed connections and add the IBOutlet to your controller object
