How to use ExtJS TreeEditor


I am quite new to extjs and I would like to have an inline editor for my tree, I know there is a TreeEditor in extjs and I am not quite sure how to use it, does anyone have a small example to get me started with the Ext.tree.TreeEditor ?

Thanks


Solution

  • Yea, this one does suck a bit because there's no good docs online. Here's a short sample, cribbed from the docs and from ExtJS in Action:

    var tree = new Ext.tree.TreePanel({
        root: this.getChildren(),
        height: 300,
        loader: new Ext.tree.TreeLoader(),
        useArrows: true,
        autoScroll: true,
        listeners: {
            dblclick: onTreeNodeDblClick
        }
    });
    
    var treeEditor = 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) {
        //o - oldValue
        //n - newValue
    }
