Laurent you are right, however I noticed a little gotcha:
If you use the following code:
panel.beginSheetModalForWindow window, completionHandler: Proc.new do
|result|
return if (result == NSCancelButton)
path = panel.filename
dest_path = applicationSupportFolder
guid = NSProcessInfo.processInfo.globallyUniqueString
dest_path = "#{dest_path}/#{guid}"
error = Pointer.new(:id)
NSFileManager.defaultManager.copyItemAtPath(path, toPath:dest_path,
error:error)
NSApp.presentError(error) if error[0]
movie.setValue(dest_path, forKey:"imagePath")
end
You get an argument error: tried to create Proc object without a block
(ArgumentError)
However using the curly brackets would work:
panel.beginSheetModalForWindow window, completionHandler: Proc.new{|result|
return if (result == NSCancelButton)
path = panel.filename
dest_path = applicationSupportFolder
guid = NSProcessInfo.processInfo.globallyUniqueString
dest_path = "#{dest_path}/#{guid}"
error = Pointer.new(:id)
NSFileManager.defaultManager.copyItemAtPath(path, toPath:dest_path,
error:error)
NSApp.presentError(error) if error[0]
movie.setValue(dest_path, forKey:"imagePath")
}
Finally, the only way to get the do/end proc approach to work is to use the
parenthesis around the arguments:
panel.beginSheetModalForWindow(window, completionHandler: Proc.new do
|result|
return if (result == NSCancelButton)
path = panel.filename
dest_path = applicationSupportFolder
guid = NSProcessInfo.processInfo.globallyUniqueString
dest_path = "#{dest_path}/#{guid}"
error = Pointer.new(:id)
NSFileManager.defaultManager.copyItemAtPath(path, toPath:dest_path,
error:error)
NSApp.presentError(error) if error[0]
movie.setValue(dest_path, forKey:"imagePath")
end)
