Drag and Drop ordering in a TreePanel using reorder.js

This example shows basic drag and drop node moving in a tree. In this implementation there are no restrictions and anything can be dropped anywhere except appending to nodes marked “leaf” (the files).

In order to demonstrate drag and drop insertion points, sorting was not enabled.
The data for this tree is asynchronously loaded through a TreeStore and AjaxProxy.
The js is not minified so it is readable. See reorder.js.

Ext.require([
'Ext.tree.*',
'Ext.data.*',
'Ext.tip.*'
]);

Ext.onReady(function() {
Ext.QuickTips.init();

var store = Ext.create('Ext.data.TreeStore', {
proxy: {
type: 'ajax',
url: 'get-nodes.php'
},
root: {
text: 'Ext JS',
id: 'src',
expanded: true
},
folderSort: true,
sorters: [{
property: 'text',
direction: 'ASC'
}]
});

var tree = Ext.create('Ext.tree.Panel', {
store: store,
viewConfig: {
plugins: {
ptype: 'treeviewdragdrop',
containerScroll: true
}
},
renderTo: 'tree-div',
height: 300,
width: 250,
title: 'Files',
useArrows: true,
dockedItems: [{
xtype: 'toolbar',
items: [{
text: 'Expand All',
handler: function(){
tree.getEl().mask('Expanding tree...');
var toolbar = this.up('toolbar');
toolbar.disable();

tree.expandAll(function() {
tree.getEl().unmask();
toolbar.enable();
});
}
}, {
text: 'Collapse All',
handler: function(){
var toolbar = this.up('toolbar');
toolbar.disable();

tree.collapseAll(function() {
toolbar.enable();
});
}
}]
}]
});
});
