hi Thomas,

I don't know if there is a way to get the TCL/TK mouse state by polling, there seem to be just mouse events... but that's not too bad - one can cache the info.
actually I need only mouse _position_ polling (or, strictly speaking, sampling), which is available by calling winfo pointerxy.
Hmmm, i don't understand the advantage of polling compared to position events. If you want to poll from TCL/TK you would have to trigger a TK function and get the values via a bound message (but you know that). So using the mouse events, cache the position and do the polling (if necessary) internally seems more convenient to me.
and what I do not know, is how to plug my object into the original flow of events destined for a canvas (or, rather, all canvases)... Any idea?
I guess in that case you would have to modify the event handlers in PD.TK, which is not very elegant.
best regards, Thomas
