Braxton, Many Thanks for your advice . I will try to cast from CGPoint to NSPoint . Nim, I will try your code . In addition to the fact that we probably run on a different OS or MacRuby version , the other difference is that you set the width and height to full constants . The division operations that you commented out produced fractions. Thank You All,David On Dec 10, 2012, at 11:35 AM, Braxton Sherouse wrote:
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:

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
