Cursor location - in pixels - in textarea

Does anyone know a multi-platform way of determining the exact location in pixels of the cursor in a textarea?
It must also work even when the text is scrolled (that's the main problem).
Even a convoluted solution, and preferably without module tweaks.

Thanks.

Take a look at this: Adding a TextAreaCursorXY

Windows & MacOSX doesnt need mod tweaking, but the Linux one does.

Thank you very much. Too bad it requires a module tweak. Based on your code, I'll probably look if I can add the feature on top of the current maxGUI implementation rather than tweaking it. I just want my code to stay self-contained and not be broken by any update.

If anyone has another solution, I'm still ready to take it.

I was kind of hoping this tweak might make itself into the official mods, seeing as it works on all three platforms...

Two new functions, TextAreaCharX() and TextAreaCharY(), are now available from the MaxGUI SVN with implementations on all platforms.
