Hi,
I was trying to setup an async callback using a proc instead of a method to
register for app launching notifications. For some reason, when I use the proc
method, I get the wrong object passed to the proc
when it gets called.
The version using a method callback:
framework 'Cocoa'
def callback notif
puts notif.class
puts notif.inspect
puts notif.userInfo.inspect
end
def launch_mail
workspace = NSWorkspace.sharedWorkspace
workspace.notificationCenter.addObserver self,
selector:'callback:',
name:NSWorkspaceDidLaunchApplicationNotification,
object:nil
workspace.launchAppWithBundleIdentifier 'com.apple.mail',
options:NSWorkspaceLaunchAsync,
additionalEventParamDescriptor:nil,
launchIdentifier:nil
end
launch_mail
NSRunLoop.currentRunLoop.runUntilDate( Time.now + 5 )
That code will work the way that I expected it to, but if I try to use a proc:
framework 'Cocoa'
callback = Proc.new { |notif|
puts notif.class
puts notif.inspect
puts notif.userInfo.inspect
}
workspace = NSWorkspace.sharedWorkspace
workspace.notificationCenter.addObserver callback,
selector:'call:',
name:NSWorkspaceDidLaunchApplicationNotification,
object:nil
workspace.launchAppWithBundleIdentifier 'com.apple.mail',
options:NSWorkspaceLaunchAsync,
additionalEventParamDescriptor:nil,
launchIdentifier:nil
NSRunLoop.currentRunLoop.runUntilDate( Time.now + 5 )
It will crash because for some reason I am not getting the notification back as
I should, instead I am getting a reference to the NSDictionary class.
I don't think this is the intended behaviour in MacRuby, but I'm not sure if
what I am trying to do is supported.
Is the ability to use a proc as a callback a supported feature? It has worked
for me in other cases.
