[9fans] winwatch

[lucio]

I replaced the code in click() with the following to add a half-baked
facility to hide a window with winwatch.  It uses the B3-B1 chord, but
somehow loses the ability to pick a window with B3 when the winwatch
window is not active.

void
click(Mouse m)
{
	int fd, w, b = m.buttons;
	Point xy = m.xy;
	char buf[128];

	do
		m = emouse();
	while(m.buttons == b);

	while (b) {
		for(w = 0; w < nwin; w++)
			if(ptinrect(xy, win[w].r))
				break;
		if(w < nwin) {
			sprint(buf, "/dev/wsys/%d/wctl", win[w].n);
			switch (b & 7) {
				case 1:
					break;
				case 2:
				case 3:
					break;
				case 4:
				case 6:
				case 7:
					if((fd = open(buf, OWRITE)) < 0)
						return;
					write(fd, "unhide\n", 7);
					write(fd, "top\n", 4);
					write(fd, "current\n", 8);
					close(fd);
					break;
				case 5:
					if((fd = open(buf, OWRITE)) < 0)
						return;
					write(fd, "top\n", 4);
					write(fd, "hide\n", 7);
					close(fd);
					break;
			}
		}
		b = m.buttons;
		xy = m.xy;
		do {
			m = emouse();
		} while (m.buttons);
	}
}

I am a little disappointed as to how complicated it is to implement
mouse functionality.  It seems a lot easier to expect the interactive
human to recover from unexpected conditions rather than try to design
the interaction so no condition is unexpected.  This is not a
criticism of Plan 9, far from it.  It is the realisation that by
putting a computer on every desk we (computer programmer, glorified or
otherwise) have turned computers from convenient slaves to eliminate
tedium to instruments requiring constant human attention.

I implemented hide once, then decided I didn't need it :-).  So did a
few other people.

And given your comment about communicating with mice is probably well
warranted :-)

Oh, I missed that, somehow.  I was beginning to think that winwatch
was more practical than the RIO menu and was hoping to head in that
direction, except that managing the mouse looked terribly daunting.
I'll see whether squeak will help my understanding, I've been
wondering about it,
