OK, me again! Being up at 2am should at least lead to some results. We
can force the treevirtual to update the cell focus indicator by adding a
"dragmove" event. Here is the full code:
myVirtualTree.addEventListener("dragmove",function(event){
this._getPaneScrollerArr()[0]._focusCellAtPagePos(event.getPageX(),
event.getPageY());
},timesTree);
myVirtualTree.addEventListener("dragdrop",function(event){
// drag source
var sourceType = event.getDropDataTypes()[0]; // type of drag object
var sourceNode = event.getData(sourceType); // object dragged
// drag target
var currentRow =
this.getDataModel().getRowData(this._getPaneScrollerArr()[0].getFocusedRow());
if ( ! currentRow ) return;
var targetNode = currentRow[0];
// do stuff
}
But I think tree and table should have this behaviour built in without
the need of an additional "dragmove" event handler.
Cheers,
Christian
