objective c - How to find absolute NSView frame position in window -

-

i have complicated hierarchy of nsviews, how can find frame of view in window or able check if point in window in views frame?

i tried this

nspoint windoworigin = [[window contentview] convertpoint:nsmakepoint(0,0) fromview:myview];

send convertrect:toview: second argument set nil:

nsrect viewframeinwindowcoords = [myview convertrect: [myview bounds] toview: nil];

on second thought, if need perform hit testing, might want opposite:

nsview *viewunderpoint = [[window contentview] hittest: locationinwindow];
