extjs4 RowEditing怎么判断处于编辑状态

extjs4 RowEditing怎么判断处于编辑状态然后不让做添加删除的动作

不是有beforeedit/edit事件事件，你用个全局变量控制就好了

   var rowEditing = Ext.create('Ext.grid.plugin.RowEditing', {
        clicksToMoveEditor: 1,
        autoCancel: false,
        listeners: { beforeedit: function () { window.editing = true }, edit: function(){window.editing=false}}
    });

    function delRow() {
        if (window.editing) { alert('正在编辑。。。。'); return false }
        //...your code
    }
