Re: Mouse interface for text mc via console telnet

Hi Pavel,

Thanx for your friendly and useful answers - much appreciated (almost as 
much as I appreciate your work on mc! :-)

Our package of emulators on Windows does not include xterm.  But I think 
we should investigate the posibility of producing one.  Since our bread-and-
butter depends on selling the package, we can not use GPL code to write 
an xterm.  (You're welcome to try our linux console - just ask.)

These limitations do not sound too hard!?

Thanx - I'll get it.

Yes - I guess that is the direction I should be looking at.
My idea was that I send an escape sequence from the terminal to mc 
giving the type of mouse-click and the position.  Something like:
"M-mouse 1 down;03;56".  It would then work from many different 
terminals, provided they can translate their mouse-clicks to the required 
string.

Yes - first things first - but it seems one never gets there  :-/
