Hi Braxton
Cocoa seems to be a bit schizophrenic when handling NSPoint and CGPoint.  I tried your advice and that what I got. Certainly one should be careful dealing with these classes !!
Thanks, David

puts "width is #{width} heght is #{height}"
origin = NSPointFromCGPoint(NSMakePoint(width,height))
puts "class of origin is #{origin.class} "

width is 160.5 heght is 184.0
class of origin is CGPoint (!!!!)

I can't speak to the encoding issues, but I can attest to crashing
issues with incorrectly assuming the compatibility of NSPoint and
CGPoint.

It depends what version of Mac OS you're on whether NSPoint can safely
be cast as a CGPoint. In older versions of Mac OS, NSPoint used float
for its members (32-bit) -- later, it switched to CGFloat (64-bit).


There are functions in the Foundation framework that you can use, if
you want to be safe: NSPointFromCGPoint and NSPointToCGPoint:

https://developer.apple.com/library/mac/#documentation/Cocoa/Reference/Foundation/Miscellaneous/Foundation_Functions/Reference/reference.html#//apple_ref/c/func/NSPointFromCGPoint


Also, check out the documentation here, on NSPoint, which gives the
version history:

Hi David,

I ran the following

framework 'cocoa'
def  initLabel(h)
      @label = NSTextField.alloc.initWithFrame(CGRectMake(0,0,250, 45))
      @label.setStringValue(h)
      @label.drawsBackground = false
      @label.bezeled = false
      @label.font = NSFont.fontWithName("Arial", size:45.0)
      @label.editable = false
      puts "class of label is #{@label.class}"
      # width =
(@window.contentView.frameSize.width/2.0)-(@label.frameSize.width/2.0)
      # height =
(@window.contentView.frameSize.height/2.0)-(@label.frameSize.height/2.0)
      width=100.0
      height=200.0
      puts "width is #{width} heght is #{height}"
      origin = NSMakePoint(width,height)
      puts "class of origin is #{origin.class}"
      @label.setFrameOrigin(origin)
      puts @label.frame.origin
end

initLabel("Hello")


I got the following output.

class of label is NSTextField
width is 100.0 heght is 200.0
class of origin is CGPoint
#<CGPoint:0x40013a340>class of origin is CGPoint
#<CGPoint:0x40013a340>

It seem be to working for me. I think NSPoint and CGPoint can be mix used.
(Free ride)
I think the problem is in the `￯﾿ﾼ￯﾿ﾼ' whatever that is

Hi Min,
This error message was produced by run environment and not by my code. I
don't do (knowingly ) anything with encoded text. Usually I get
comprehendible error messages when my code crashes.
Thanks, David

Hello David,

In your error message it says

undefined method `￯﾿ﾼ￯﾿ﾼ'


Why are you getting `￯﾿ﾼ￯﾿ﾼ' instead of 'setFrameOrigin'?
Do you have some foreign encoded text somewhere?

Hello,
I am trying to create an NSPoint object so I can call setFrameOrigin but I
get in response a CGPoint object . When I pass the CGPoint to setFrameOrigin
, it crashes. How do I make NSMakePoint making an NSPoint object and not a
CGPoint object.
Thank you for  your help,
David Kramf
