function `frame-parameters' on mac osx

function `frame-parameters' on mac osx

[leo]

hi there

i did some experiments with emacs frames on windows 2000 and mac osx and i
discovered an odd behaviour on mac osx:

the function (frame-parameters FRAME) returns the parameters-alist of a
frame. when i use it on windows it reveals in the 'left'- and 'top'-pairs
always the correct values.

under mac osx it shows the 'left'- and 'top'-pairs only correctly as long as
i do not change the frame postion manually by dragging the window. after
dragging the window, a new call of `frame-parameters' reveals still the old
values for left and top!

that's really strange and inconvinient; particularly when you want to create
new frames depending on the position of existing frames.

it might be worth mentioning that i use on mac osx the aqua version of
emacs, not the X11 version, so, i don't know, but it could be an aqua issue.
does somebody knows: does it happen under X11 as well?

thanks, leo

definitely an aqua/carbon issue (was Re: function `frame-parameters' on mac osx)

a quick update on the frames issue:

i have checked out emacs as an x11 build on mac osx. and guess what,
`frame-parameters' and all the things about frame-positions work fine! so
its definitely an aqua/carbon issue.

i'm eager to look in the source, where the problem comes from but don't know
where to start... is there any documentation about the structure of the c
source of emacs and its platform related stuff available?

cheers, leo
