In my dragdrop.js file there is a line (can''t remember if I added it or
if it was there to begin with, lol) that prevents text selection while
dragging a Draggable object... you could use something similar at a
global level if you don''t just want to limit the behavior to
Draggables.
The register() method of "Draggables" looks like this...
register: function(draggable) {
if(this.drags.length == 0) {
this.eventMouseUp = this.endDrag.bindAsEventListener(this);
this.eventMouseMove = this.updateDrag.bindAsEventListener(this);
this.eventKeypress = this.keyPress.bindAsEventListener(this);
Event.observe(document, "mouseup", this.eventMouseUp);
Event.observe(document, "mousemove", this.eventMouseMove);
Event.observe(document, "keypress", this.eventKeypress);
// prevent text selection while dragging.
document.onselectstart = document.ondragstart = function() {
return this.activeDraggable == null; }.bind(this);
}
this.drags.push(draggable);
},

achieved? When I try to select cells in a column by dragging over them
the text within rows gets selected as well.
