[MacRuby-devel] Fwd: Warnings from print operation

Hi Laurent:

Thanks for your reply. I'll try to reproduce the problem with a stripped down version of my app - It could be useful as a sample script if it doesn't reproduce the problem.

Far as I can tell I'm building for 10.5.

I get the warnings by running the PrintOperation modally as follows:

class SimpleX_ViewController < NSViewController
	def init
		if super
			puts "SimpleX_ViewController"
			initWithNibName( 'SimpleX', bundle:nil )
			loadView()
		end
		
		self
	end

	# selector for printOperationDidRun is not recognized
	def printOperationDidRun( printOperation, success:success, contextInfo:info )
		puts "printOperationDidRun #{ success }"
	end

	def print
		puts "#{ self.class }.print"
		printInfo = NSPrintInfo.sharedPrintInfo
		puts "printInfo #{ printInfo.dictionary.inspect }"
		
		printOperation = NSPrintOperation.printOperationWithView( @printableView )
		printOperation.runOperationModalForWindow( view().window, delegate:self, didRunSelector:"printOperationDidRun:", contextInfo:nil )
	end
end

class SimpleX_View < NSView
	include DrawUtilities
	def drawRect( rect )
		@context = NSGraphicsContext.currentContext.graphicsPort # returns invalid context
		puts "SimpleX_View #{ @context.class }"
		DrawX( bounds )
	end

	def beginDocument
		puts "Got beginDocument"
		super # Should create the graphics context but operations returns nil for context
	end
	
	def knowsPageRange( rangePtr ) # Override pagination. Image may clip on some printers
		rangePtr[ 0 ] = NSMakeRange( 1, 1 )
		
		true
	end
	
	def rectForPage( page ); bounds; end # Use IB layout size. page should be 1
	
	def locationOfPrintRect( rect ) # Called only once for printing
		puts "locationOfPrintRect"
		
		currentOperation = NSPrintOperation.currentOperation
		puts "currentOperation #{ currentOperation.class }"
		context = currentOperation.context
		puts "context #{ currentOperation.context.class }"
		if context.nil?
			puts "Invalid NSPrintOperation contect"
		end
		puts "view #{ currentOperation.view.class }" # OK
		
		super # super returns NSMakePoint( 0, 0 )
	end
end

Thanks,
Bob Rice

Printing had stopped working for the views in my application so I tried creating my own PrintOperation and ran it modally for my window instead of routing the print command directly to the view. Then the warnings appeared. Could my project be linked to an old framework or Ruby library?
