Occurs when item is dragged into TreeView space.
| Param | Type | Details |
|---|---|---|
| e | Object | An event object which contains the dragItem and mousePos objects |
This event can be handled by binding the 'dragenter' event to the TreeView widget object.
The mousePos object associated with this event holds coordinates of mouse position relative to the parent page.
Supported in: v1.0.
In this example we are showing how to handle dragenter event in TreeView widget.
$(document).ready(function() {
// Create an instance of TreeView widget
var $tree = $('#treeview').treeview();
$tree.on({
"dragenter": function(e){
if (e.dragItem)
alert("Item: " + e.dragItem.text + " is dragged at position: { x: " + e.mousePos.x + ", y: " + e.mousePos.y + " }");
});
});
