I am making a theme in which I wish to have a dynamic systemtray at the bottom right corner... making the tray is no problem, but one thing that I had wanted to do is make the edge pixels popup the tray on hover. I can do this just setting the corner pixels to do this, but that requires unneccesary mouse movement... so I was hoping to make the bottom of the desktop to popup the tray judging from how long my autosized tray is. The problem with this is I'm not sure how to go about finding the length of the tray so that I can set it to a variable... Thanks a lot if you can figure this out... this bugged me for a while.

you could probably use the *SystrayOnAdd / OnDel commands combined with mzscript or so. Those commands are executed whenever an icon is added/deleted (doh) to/from the tray.

The size of the systray is already set to a variable: $SystrayCurrentWidth$ and $SystrayCurrentHeight$ (ok, two of them)

Good luck using it though, you need some way to avoid having these evaluated at startup. (it is possible)

that's always good to know, but i have a question -- is there a variable set to the current size of a dynamic folder from popup?
