Button frame to screen rect

  • What would be the easiest way to convert the frame rect of a button in
    a window to a screen rect ?

    My goal is to have a window animate out from this button.

    For some reason (perhaps lack of coffee), i'm not able to wrap my
    brain around the various convert methods for views.

    Thanks!

    Search the documentation for symbols beginning with "convert"; among the results:

    It converts NSPoints, but you can do the math. You may want to start with the bounds rect of the button, and use -[NSView convertPoint:toView:] with the second argument nil; it will keep working if you ever move the button to an enclosing view.

  • Thanks  for your help.

    From this then, I would use the origin point ... of the bounds or
    frame of the button rect, which would give me the equivalent in screen
    coordinates and then just adjust the width/height as necessary for my
    window ?

    Again, my thanks
