I obviously didn't remember it correctly and forgot about the timout stuff.
My implementation below works completely within Jmol without any
Javascript. One advantage of this is that it also works in the Jmol
application. The 'halo' color is changed to distinguish the 'hover halo'
from a yellow 'selection halo' which might be already there before the
'hover' (setting: "selectionHalos on").
It took me some time to figure out how to avoid flickering because the
callback might be fired multiple times for the same atom if the mouse
pointer rests longer above it. This might not be a problem if
activating/deactivating the halo is the only action. But in my case
there was some more stuff which I stripped out here.
While stripping out the additional stuff I realized that there might
occur a problem if the 'lastAtomIndexHovered' variable would change too
fast, although I never observed any problem with it yet. But maybe it
would be better to provide the atomIndex as a second parameter in the
"hoverAction('end')" call.
------ Jmolscript hover callback implementation ---------------
lastAtomIndexHovered = -1;
lastHoverUnfinished = false;
hoverTimeoutId = "";
function hoverAction(action) {
#print "action=" + action + " hoverId=" + hoverTimeoutId;
if (hoverTimeoutId != "") {
timeout ID @hoverTimeoutId off;
hoverTimeoutId = "";
}
var switchOff = false;
var currentSelection = {selected};
if (action == "end") {
if (lastHoverUnfinished) {
switchOff = true;
}
} elseif (action == "start") {
if (lastHoverUnfinished) {
if (lastAtomIndexHovered != _atomhovered) {
switchOff = true;
}
}
}
#print "action=" + action + " switchOff=" + switchOff + "
lastHoverUnfinished=" + lastHoverUnfinished + " lastAtomIndexHovered="
+ lastAtomIndexHovered + " _atomhovered=" + _atomhovered;
if (switchOff) {
if (lastAtomIndexHovered >= 0) {
select atomindex=@lastAtomIndexHovered;
color halo yellow;
halo off;
}
lastAtomIndexHovered = -1;
lastHoverUnfinished = false;
}
if (_atomhovered >= 0 && action == "start") {
lastAtomIndexHovered = _atomhovered;
select atomindex=@lastAtomIndexHovered;
color halo cyan;
halo on;
lastHoverUnfinished = true;
hoverTimeoutId = "hoverEnd_" + now();
timeout ID @hoverTimeoutId 1.0 "hoverAction('end')";
}
select @currentSelection;
}
set hoverCallback "jmolscript: hoverAction('start');";
