How do I remove all formatting (setUsesRuler:NO does not work) from an NSTextView?

• Gerben Wierda How do I remove all formatting (setUsesRuler:NO does not work) from an NSTextView? Sep 20 2002, 17:25
  I have an NSTextView that alternately displays RTF data and ASCII data.
  When the RTF data has been displayed, some aspects of it linger, mainly
  the ruler. When I display pure ASCII the text displays indented.
  
  I tried:
  
  [__inspectView setRichText:NO];
  [__inspectView setUsesRuler:NO];
  [__inspectView setFont:__fixedFont];
  
  but to no avail, the ASCII text is displayed indented. What am I missing
  here?
  
  Thanks,
  
  G

  If I understand your problem correctly, replacing the above code with
  the following, which restores the default alignment
  (NSNaturalTextAlignment), ought to solve it:
  
  NSParagraphStyle *paraStyle = [NSParagraphStyle defaultParagraphStyle];
  
  [[__inspectView textStorage] addAttribute:NSParagraphStyleAttributeName
  value:paraStyle range:NSMakeRange(0, [[__inspectView string] length])];
  
  Note, it will only work if there is text in the view, but it should be
  easy enough to overcome this limitation. Hope this helps.

  Specifically what you are missing is the paragraph style; however,
  there are other attributes you may wish to consider.  Here is the
  relevant method from the TextEdit example, which in addition to what
  you are doing, also applies a default set of attributes to the entire
  text (and sets them as the typing attributes), and removes any
  attachments:
  
  - (void)setRichText:(BOOL)flag {
      NSTextView *view = [self firstTextView];
      NSDictionary *textAttributes;
  
      isRichText = flag;
  
      if (!isRichText) [self removeAttachments];
  
      [view setRichText:isRichText];
      [view setUsesRuler:isRichText];    /* If NO, this correctly gets rid
  of the ruler if it was up */
      if (isRichText && [[Preferences objectForKey:ShowRuler] boolValue])
  [view setRulerVisible:YES];    /* Show ruler if rich, and desired */
      [view setImportsGraphics:isRichText];
  
      textAttributes = [self defaultTextAttributes:isRichText];
  
      if ([textStorage length]) {
          [textStorage setAttributes:textAttributes range: NSMakeRange(0,
  [textStorage length])];
      }
      [view setTypingAttributes:textAttributes];
  }
