Way to detect window position on Mac?

Hmm, again I think it nearly works. It compiles and runs but I don't seem to be able to use the returned theOrigin properly (when I try to Print theOrigin.X the app just crashes even in debug mode). I looked up NSPoint on developer.apple.com and it is simply a struct with x and y fields as FLOATS, nothing else.

Here's what I have so far:

This file is called cocoamouse.m

#include <AppKit/AppKit.h>

void ccNSGetCursorPos(int *x,int *y){
	NSPoint mouseLoc = [NSEvent mouseLocation];
	*x = mouseLoc.x;
	*y = mouseLoc.y;
}

int getActiveWindowOSX(){
    NSAutoreleasePool *pool=[[NSAutoreleasePool alloc] init];
    NSApplication *myApp;
    myApp=[NSApplication sharedApplication];
    NSWindow *myWindow = [myApp keyWindow];
    [pool release];
//    return *NSWindow;
}

NSPoint ccGetWindowOrigin(){
    NSApplication *myApp = [NSApplication sharedApplication];
    NSWindow *myWindow = [myApp keyWindow];
    NSRect myFrame = [myWindow frame];
    NSPoint theOrigin = myFrame.origin;
    return theOrigin;
};

And here is my test code:

SuperStrict

Import "cocoa_mouse.m"

Extern
	Function ccNSGetCursorPos(x:Int Ptr, y:Int Ptr)
	Function ccGetWindowOrigin: TAccuratePoint()
End Extern

Type TAccuratePoint
	Field X#
	Field Y#
End Type

Function GetScreenPointerPos(x:Int Var, y:Int Var)
	ccNSGetCursorPos(Varptr x, Varptr y)
End Function

Graphics 640,480, 0

While Not KeyDown(KEY_ESCAPE)

    Cls

    Local x:Int, y:Int
    GetScreenPointerPos(x, y)

    DrawText "Pos = " + x + ", " + y, 50, 50
	Local p:TAccuratePoint = ccGetWindowOrigin()
	Print p.x
    Flip

Wend

End

I tried this:

Function ccGetWindowOrigin: Bye Ptr()

but it wouldn't compile, said "Unable to convert from 'Byte Ptr' to 'TAccuratePoint'"

Any ideas? Thx.
