MyDesktop.BogusModule = Ext.extend(Ext.app.Module, {
                    init : function(){
                        this.launcher = {
                            text: 'Window '+(++windowIndex),
                            iconCls:'bogus',
                            handler : this.createWindow,
                            scope: this,
                            windowId:windowIndex
                        }
                    }, //end init                    createWindow : function(src){
                        var desktop = this.app.getDesktop();
                        var win = desktop.getWindow('bogus'+src.windowId);
                        if(!win){

                            win = desktop.createWindow({
                                id: 'bogus'+src.windowId,
                                title:src.text,
                                width:1024,
                                height:768,

                                constrainHeader:true
                            });
                        }
                        win.show();
                    } //end createWindow
                }); //end MyDesktop.BogusModule                var shipManage = Ext.extend(MyDesktop.BogusModule, {
                    init : function(){
                        this.launcher = {
                            text: '船舶管理',
                            iconCls: 'bogus',
                            handler: function() {
                                return false;
                            },
                            menu: {
                                items:[{//0
                                        text: "船舶公司信息",
                                        iconCls:'icon-grid',
                                        handler : this.createWindow,
                                        scope: this,
                                        url:"./shipManage/shipCorp.html",
                                        windowId: ++windowIndex
                                    },{//1
                                        text: "船舶信息",
                                        iconCls:'icon-grid',
                                        handler : this.createWindow,
                                        scope: this,
                                        url:"./shipManage/ship.html",
                                        windowId: ++windowIndex
                                    }]//end items
                            }//end menu
                        }//end launcher
                        if(purview.substr(1,1)=="0"){//控制船舶公司信息
                            this.launcher.menu.items.remove(this.launcher.menu.items[0]);
                        }
                        if(purview.substr(2,1)=="0"){//控制船舶信息
                            this.launcher.menu.items.remove(this.launcher.menu.items[1]);
                        }
                    }//end init
                });类似这样的一个，我想从数据库取出来动态生成desktop的start
