Changing the I-beam cursor over a text view

[fiz]

Hello,

Is there a way to set the cursor to a pointing hand over a text view without subclassing NSTextView?

I read a lot about NSTrackingAreas, tested a lot of examples, set different tracking options and implemented different methods, but the cursor still remains an I-Beam. I have read that it is an AppKit automatic feature, so how can I prevent this?

Thank you!

Edit for Stefan: I read this

You change the cursor image for your view in an override of the NSResponder method cursorUpdate:. To receive this message, you must create an NSTrackingArea object by invoking the initWithRect:options:owner:userInfo: initializer with an option of NSTrackingCursorUpdate (along with any other desired options). Then add the created object to a view with addTrackingArea:. Thereafter, the entry of the mouse into the tracking area generates an NSCursorUpdate event; the NSWindow object handles this event by sending a cursorUpdate: message to the owner of the tracking area (which is typically the view itself). The implementation of cursorUpdate: should use the appropriate NSCursor methods to set a standard or custom cursor image.

And.

#import “ATTextView.h”

@implementation ATTextView

• (id)initWithFrame:(NSRect)frame
  {
  self = [super initWithFrame:frame];
  if (self) {
  NSTrackingArea *trackingArea = [[NSTrackingArea alloc]initWithRect:self.bounds options:NSTrackingCursorUpdate | NSTrackingActiveInActiveApp owner:self userInfo:nil];
  [self addTrackingArea:trackingArea];
  }
  return self;
  }

• (void)cursorUpdate:(NSEvent *)event
  {
  [[NSCursor pointingHandCursor]set];
  }
  @end

doesn’t work. I found numerous references on the web, including. bug reporting.

So it seems to be an other «macramé thing». Have a simple idea like “Set the cursor to a «pointing hand» over a text view”, and you end up with subclassing and lines of incredibly verbose (and not working) code.

This finally worked

@implementation ATTextView

• (id)initWithFrame:(NSRect)frame
  {
  self = [super initWithFrame:frame];
  if (self) {
  _trackingArea = [[NSTrackingArea alloc]initWithRect:[self bounds] options: (NSTrackingMouseMoved | NSTrackingActiveInKeyWindow) owner:self userInfo:nil];
  [self addTrackingArea:_trackingArea];
  }
  return self;
  }

• (void)mouseMoved:(NSEvent *)event
  {
  if ([self isEditable]) [[NSCursor IBeamCursor] set];
  else [[NSCursor pointingHandCursor] set];
  }

• (void)updateTrackingAreas {
  [super updateTrackingAreas];
  [self removeTrackingArea:_trackingArea];
  _trackingArea = [[NSTrackingArea alloc] initWithRect:[self bounds] options: (NSTrackingMouseMoved | NSTrackingActiveInKeyWindow) owner:self userInfo:nil];
  [self addTrackingArea:_trackingArea];
  }
  @end

Just to find the correct example (Cocoa is 80% doc reading and 20% coding):
