What's the rule to convert CocoaAPI to MacRuby API

Question

- (BOOL)applicationShouldHandleReopen:(NSApplication *)theApplication hasVisibleWindows:     (BOOL)flag
{
[self showWindow:self];
return YES;
}

how to convert this method to MacRuby ?

I tried

def applicationShouldHandleReopen(the_application, k)   
    @window.makeKeyAndOrderFront
end

but not works

Answer 1

You need to use the selector syntax for the 2nd argument, e.g.:

def applicationShouldHandleReopen(the_application, hasVisibleWindows:k)
    ...
end
