16 * @class Ext.tree.TreeEditor
18 * Provides editor functionality for inline tree node editing. Any valid {@link Ext.form.Field} subclass can be used
19 * as the editor field.
21 * @param {TreePanel} tree
22 * @param {Object} fieldConfig (optional) Either a prebuilt {@link Ext.form.Field} instance or a Field config object
23 * that will be applied to the default field instance (defaults to a {@link Ext.form.TextField}).
24 * @param {Object} config (optional) A TreeEditor config object

44 * The position to align to (see {@link Ext.Element#alignTo} for more details, defaults to "l-l").
49 <div id="cfg-Ext.tree.TreeEditor-hideEl"></div>/**
50 * @cfg {Boolean} hideEl
51 * True to hide the bound element while the editor is displayed (defaults to false)

61 * True to shim the editor if selects/iframes could be displayed beneath it (defaults to false)
66 <div id="cfg-Ext.tree.TreeEditor-maxWidth"></div>/**
67 * @cfg {Number} maxWidth
68 * The maximum width in pixels of the editor field (defaults to 250). Note that if the maxWidth would exceed
69 * the containing tree element's size, it will be automatically limited for you to the container width, taking
70 * scroll and client offsets into account prior to each edit.
73 <div id="cfg-Ext.tree.TreeEditor-editDelay"></div>/**
74 * @cfg {Number} editDelay The number of milliseconds between clicks to register a double-click that will trigger
75 * editing on the current node (defaults to 350). If two clicks occur on the same node within this time span,
76 * the editor for the node will display, otherwise it will be processed as a regular click.
