[PD-dev] PD canvas interaction - flext GUI

No, no reply.... so i'm trying to get from pd what i can without having to
use bad/non-portable tricks.
That is:
- key down and up .... this is generally really dirty stuff in PD, there are
no scan codes in TCL/TK, just ascii and extended key names
- mouse down and mouse dragging (also outside the object rectangle)
- idle mouse position

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.

These were just examples how PD itself could make use of all the possible
information. Looking at PD.TK this is not fully exploited.
I can hardly use these code fragments for flext as they would intercept all
TCL/TK events. Resending them or modifying PD.TK seems to be non-portable to
me as it is very likely to collide with other externals making use of such
tricks.

Generally i have to say that i'm (after a short recovery) more and more fed
up with TCL/TK. Although it's not a bad system i consider it unsuitable for
a multi-media environment. It's a dead-end street.
Just had a deeper look at Max/Jitter. It's just incredible.

greetings,
Thomas
