C Code to add a Cocoa Window to and Igor XOP

<br />
<br />
<br />
// I subclassed NSWindow, mainly so I could handle keydown events.<br />
// I subclassed NSWindowController to handle actions from controls in the window.<br />
// I store the window and its controller in global variables.<br />
MyWindowClass*      myCocoaWindow;<br />
MyWindowController* myWinController;<br />
<br />
// Create the window and its controller.  I store the NSWindow and the NSWindowController<br />
// in global variables, but you could return them.<br />
// I also never release the window, so it just gets hidden when closed.  If you want to<br />
// release it, you could do that (and remember to nil out the global variable!) in<br />
// the delegate's WindowWillClose method, or in the window's Close method (assuming you<br />
// subclass NSWindow).<br />
