Re: [EXP] Getting the pixel position of a window point

[ This is experimental, and thus is not (yet) being submitted to xemacs-patches. ] Here's an experimental patch for 21.2 that provides a way of getting the window pixel co-ordinates of a window point. I found that the function, "current-pixel-column", already existed, and so I just added the corresponding function, "current-pixel-row". However, there's a big "gotcha" (issue) with these functions: they both use the redisplay tables to determine the pixel position. This basically means that a screen update/refresh must be done (e.g., "(sit-for 0)") before these functions will return correct values. For newly-created frames, you have to do something like this instead: ;; idea stolen from set-mouse-position (while (not (frame-visible-p frame)) (sleep-for .5)) Unfortunately, there doesn't seem to be a better way.
