Hi, I have recently started programming on Mac using Objective-C and Cocoa. I am coming from C++/C# world. So, its a fairly basic question. Please help me understand the following code: @implementation MyView /*MyView inherits from NSView */ -(void)drawRect: (NSRect)aRect { [[NSColor blackColor] set]; NSRectFill( [self bounds] ); } In first line, I was expecting something like [self setColor:[NSColor blackColor]]; (similar to this.color = NSColor.blackColor; in C#/C++) how NSColor object knows about where to set the color? In second line, NSRectFill(), I was expecting it to be called using square bracket [] notation. Again how this function knows where to fill the rectangle? There is no reference of NSView passed into the function? Lastly what are the rules of using () verses []? Thanks in advance for your time! -Vks
