osx - Mac Mouse Coordinates != Window Frame? -

here's issue. can explain enough. desktop 2x2 monitors of size (2048,1152).

i'm trying use ancillary device generate mouse clicks. mouse click supposed on coordinate (1600,1407)-ish (on "pan button"), assuming (0,0) top-left of entire desktop area. moves mouse correct position, when perform cgrectcontainspoint()) gives me no result.

the rectangle(frame) given pop-up window has origin of (1558,-406)? math correct cgrectcontainspoint(), window's frame should contain point. (even more can see mouse cursor on window.)

why? because child window? (center of desktop in center of image, each window different background color.)

i have tried using following:

nsrect pframe = [_popupwindow frame]; nspoint porigin = pframe.origin; nspoint correctedorigin = [[_popupwindow parentwindow] convertbasetoscreen:porigin]; pframe.origin = correctedorigin; 

but gives me:

... rect {{1488, -1529}, {439, 306}}, point {1556.17, 1314.76}, inrect 0

as result, still doesn't place point (which can see hovering on pop-up window) in rect.

why rect popup window , point not remotely same? how can them in same coordinate "space"?

thanks,

on mac, (0,0) in bottom-left corner. how getting mouse coordinates? window's frame in screen coordinates, if point in it's base coordinates need call point = [window convertbasetoscreen:point]; before comparing.

here 2 ways mouse location in cocoa:

nspoint location = [nsevent mouselocation]; //already in screen coordinates, no need convert 

or

//window variable containing window nspoint location = [window mouselocationoutsideofeventstream]; //convert screen coordinates location = [window convertbasetoscreen:location];
