I actually needed this too, and had been testing this from one of your
previous posts, I added the code to dragevents.js like this:
replace line 86:
lyr.moveTo(x,y);
with this:
if (!lyr.dragging){
lyr.dragging=true;
lyr.moveTo(x,y);
lyr.dragging=false;
}else{
window.status+="/";
};
The last bit was a test, to see how often "if (!lyr.dragging)" actually
catches a premature drag call, and the answer is surprisingly NEVER.
So the code doesn't actually do anything like this.
So I thought maybe "lyr.dragging=false;" had to be set from an eventlistener
that listens for the move event, so it is only set when the layer has been
moved. So I added this:
DragEvent.lyrListener.onmove=function(e) {
var lyr=e.src;
lyr.dragging=false;
}
But still I couldn't trap any premature drag calls, so although I understand
the logic of the fix, it looks like this is being done by the dragcode quite
effectively already. (or else I made a mistake somewhere)
