Creating a Button

Creating a button is quite easy:

NSButton *myButton;

myButton = AUTORELEASE ([NSButton new]);
[myButton setTitle: @"Print Hello!"];
[myButton sizeToFit];

setTitle: sets the title (string) to be displayed on the button; sizeToFit resizes the button so that it fits the title it is displaying.

Next, we need to set target and action of the button:

[myButton setTarget: self];
[myButton setAction: @selector (printHello:)];

(self will refer to our custom object)
