xwinclip - update and motif clipboard

[Chris Twiner]

Hi All,

Quick update, got the signal working properly for ctrl-c or closing the 
windows command window.  Solution (as the SIGINT handler is run in a 
seperate thread in windows) is to set a variable in the windows loop that 
sends the kill message that kill_xwinclip was doing.

That means that all the kill_.. apps that I wanted to get rid of can be (and 
have). It also means that I don't need a window to handle turning on and off 
clipboard operations a simple close of the window would be sufficient.

Also I believe that handling the xIO error as a thread within XWin should be 
possible but I'd still be tempted to run it seperately as xwinclip.  It 
could work integrated if it was run as a seperate thread (would need to be 
anyway really), as such longjmp and setjmp should affect only that thread.  
Again I don't see how much sense this really makes.

I do have a remaining issue that I'd like to solve, CLIPBOARD operations. 
The problem seems to be the application I'm using i.e. NEdit uses Motif 
programming interfaces (or lesstif) in the default distribution.  This 
leaves four questions :

1) Should we try to get Motif clipboard operations (like klipper)?
2) If so how do we identify that what client owns the clipboard is a motif 
one (to use the motif mechanism for getting the clipboard data)?
3) Should we try to get motif clipboard before the X clipboard or after?
4) How exactly do we get the motif clipboard?

I belive 1) should be a yes but as yet I'm at a loss to attempt the other 3 
questions.  I have read that the root window property CLIPBOARD holds the 
clipboard for Motif apps but xprop dumps when i do
xprop -root CLIPBOARD.

Either way I've have only just started looking at that issue and I'm just 
about to read

But any help would be nice from someone who knows the answers now :-)

anywho,

chris

PS (Jehan and Harold, it was all tab characters that I was inserting, I'll 
change them to the two space's that Harold uses).
