Extjs Tree editor - disable single click to edit

I am using tree editor. I need the tree node to become editable only when it is double clicked. So far I have done this

  var tree = new Ext.tree.TreePanel({
      root: this.getChildren(),
      height: 300,
      loader: new Ext.tree.TreeLoader(),
      useArrows: true,
      autoScroll: true,
      listeners: {
          dblclick: onTreeNodeDblClick
      }
  });

  var tre开发者_开发技巧eEditor = new Ext.tree.TreeEditor(tree, {}, {
      cancelOnEsc: true,
      completeOnEnter: true,
      selectOnFocus: true,
      allowBlank: false,
      listeners: {
          complete: onTreeEditComplete
      }
  });

  onTreeNodeDblClick: function (n) {
      treeEditor.editNode = n;
      treeEditor.startEdit(n.ui.textNode);
  }

  onTreeEditComplete: function (treeEditor, o, n) {}

I have searched the api to find something like "clicksToEdit" which we use in editor grid but cant find anything. Is there any way to do this?

Ext.tree.TreeEditor adds two event listeners (beforeclick, dblclick) to tree so you may unsubscribe its from tree

tree.on('afterrender', function() {
    tree.un('beforeclick', treeEditor.beforeNodeClick, treeEditor);
    tree.un('dblclick', treeEditor.onNodeDblClick, treeEditor);
})

From API of Ext.tree.TreePanel:

beforeclick : ( Node node, Ext.EventObject e )

Fires before click processing on a node. Return false to cancel the default action.

So you could do this:

var tree = new Ext.tree.TreePanel({
  root: this.getChildren(),
  height: 300,
  loader: new Ext.tree.TreeLoader(),
  useArrows: true,
  autoScroll: true,
  listeners: {
      dblclick: onTreeNodeDblClick,
      beforeclick: function() { return false;}
  }

});
