Recall that Cocoa uses cartesian coordinates so y-increase is up. + +It isn't clearly documented but visibleFrame returns a rectangle in screen coordinates, not a rectangle +relative to that screen's frame. The only real way to test this is to configure two screens one atop +the other such that the menubar screen is on top. The Dock at the bottom of the screen will then +eat into the visibleFrame of screen 1 by incrementing it's y-origin. Thus if you arrange two +1920x1200 screens top/bottom then screen 1 (the bottom screen) will have frame origin (0,-1200) and +visibleFrame origin (0,-1149) which is exactly 51 pixels higher than the full frame origin. + +In wxCocoa, we somewhat arbitrarily declare that wx (0,0) is the TOP-left of screen 0's frame (the entire screen). +However, this isn't entirely arbitrary because the Quartz Display Services (CGDisplay) uses this same scheme. +This works out nicely because wxCocoa's wxDisplay is implemented using Quartz Display Services instead of NSScreen. +*/ + +namespace { // file namespace + +class wxCocoaPrivateScreenCoordinateTransformer +{ + DECLARE_NO_COPY_CLASS(wxCocoaPrivateScreenCoordinateTransformer) +public: + wxCocoaPrivateScreenCoordinateTransformer(); + ~wxCocoaPrivateScreenCoordinateTransformer(); + wxPoint OriginInWxDisplayCoordinatesForRectInCocoaScreenCoordinates(NSRect windowFrame); + NSPoint OriginInCocoaScreenCoordinatesForRectInWxDisplayCoordinates(wxCoord x, wxCoord y, wxCoord width, wxCoord height, bool keepOriginVisible); + +protected: + NSScreen *m_screenZero; + NSRect m_screenZeroFrame; +}; + +// NOTE: This is intended to be a short-lived object.
