I think you want "break" instead of "return". You can't return from a block (Proc). -Gabriel On Wed, Mar 30, 2011 at 7:53 AM, Martin Hawkins <martin.hawkins@gmail.com>wrote:
From what I can read in the archives, this was raised about 18 months ago. Loosely following Matt's book, I've written the following code: def showOpenPanel( sender) openPanel = NSOpenPanel.openPanel openPanel.setCanChooseDirectories( false)
openPanel.setShowsHiddenFiles( NSUserDefaults.standardUserDefaults.boolForKey( 'showHiddenFiles')) openPanel.setAllowsMultipleSelection( true) openPanel.beginSheetModalForWindow window, completionHandler: Proc.new{|result| return if (result == NSCancelButton) # throws error } end
The result is (on OS X 10.7, MacRuby 0.10), when the cancel button is pressed, uncaught Objective-C/C++ exception... terminate called after throwing an instance of 'RoxorReturnFromBlockException*' Program received signal: “SIGABRT”. sharedlibrary apply-load-rules all
Interestingly, on Lion, the output then appears to loop: unable to read unknown load command 0x24 unable to read unknown load command 0x26 unable to read unknown load command 0x24 unable to read unknown load command 0x26 . .
