这是我要创建的小部件。目标是让 stackContainer 由顶部的单选按钮控制。

我已经尝试过 dojo 文档中的示例，但它具有相同的错误行为。

define(["dojo/ready",  "dojo/_base/declare", "dijit/_WidgetBase", "dojo/dom-construct", 
        "dojo/_base/lang", "dojo/on", "dojo/dom-attr", "dijit/form/RadioButton", 
        "dojo/dom-style", "dijit/layout/ContentPane", "dijit/layout/StackContainer", 
        "tcs/Log"], 
function(ready, declare, _WidgetBase, domConstruct, 
         lang, on, attr, RadioButton, 
         style, ContentPane, StackContainer, 
         log) {

    /**
     * @class
     * @name gijit.workflow.debug.combi
     */
    return declare("gijit.workflow.debug.combi", [_WidgetBase], {
        workflow : null,
        panes : null,
        width : "600px",
        height : "400px",

        _beforeCall : function(d) {
            alert("beforeCall");
        },

        buildRendering : function() {
            this.domNode = domConstruct.create("div", {id:"myform"});
            var contain = domConstruct.create("div", null, this.domNode, "last");
            var stackContainer = new StackContainer({
                style: "height: " + this.height + "; width: " + this.width + "; border: 0px solid red"
            }, contain);
            var buttons = domConstruct.create("form", null, this.domNode, "first");
            for(var i=0; i<this.panes.length; i++){
                var contentPane = new ContentPane({
                    id : this.panes[i].title,
                    title : this.panes[i].title,
                    content : this.panes[i].content
                })
                stackContainer.addChild(contentPane);

                var buttonDiv = domConstruct.create("span", null, buttons, "last");
                style.set(buttonDiv, "display", "inline-block");
                style.set(buttonDiv, "margin", "10px");

                var label = domConstruct.create("div", {innerHTML: this.panes[i].title}, buttonDiv, "last");

                if(i==0){
                    var RButton = new RadioButton({
                        title : this.panes[i].title,
                        showTitle : true,
                        checked : true,
                        value : this.panes[i].title, 
                        name : "options",
                        onClick : function(a){stackContainer.selectChild(a.explicitOriginalTarget.attributes.value.textContent)}
                    }).placeAt(buttonDiv);
                } else {
                    var RButton = new RadioButton({
                        title : this.panes[i].title,
                        showTitle : true,
                        checked : false,
                        value : this.panes[i].title,
                        name : "options",
                        onClick : function(a){stackContainer.selectChild(a.explicitOriginalTarget.attributes.value.textContent)}
                    }).placeAt(buttonDiv);
                }
                contentPane.resize();
                contentPane.startup();
            }
            stackContainer.startup();
                    //Hacks in attempt to get the stuff to show
            for(var i=0; i<stackContainer.getChildren().length; i++){
                stackContainer.getChildren()[i].startup();
                stackContainer.getChildren()[i].resize();
                if(typeof stackContainer.getChildren()[i].getChildren()[0] === 'object'){
                    stackContainer.getChildren()[i].getChildren()[0].startup(); 
                }
            }
            stackContainer.resize();
        },
    });
});

在大多数情况下，它有效。但是为了显示任何东西，我必须调整窗口大小。所有的调整大小/启动调用都是在它最初不起作用之后添加的，但它们都没有做任何事情。

如果您以编程方式将子小部件添加到小部件，则需要定义启动子小部件的启动函数。每当创建新实例并将其放置在 dom 中时，都应该调用该启动函数。例如：

require(["dojo/ready", "dojo/_base/declare", "dijit/_WidgetBase", "dojo/dom-construct",
  "dojo/_base/lang", "dojo/on", "dojo/dom-attr", "dijit/form/RadioButton",
  "dojo/dom-style", "dijit/layout/ContentPane", "dijit/layout/StackContainer"],

function (ready, declare, _WidgetBase, domConstruct,
lang, on, attr, RadioButton,
style, ContentPane, StackContainer) {


  var MyClass = declare("gijit.workflow.debug.combi", [_WidgetBase], {
    startup: function () {
      this.inherited(arguments);
      stackContainer.startup();
    }
  });
  var x = new MyClass({});
  x.placeAt('node');
//manually call startup after instantiating the widget.  If  the parser is what is creating your widget, it calls startup automatically.  startup must be called after the widget is in the dom.
  x.startup();
  console.log(x);
});

使您的小部件子类成为ContentPane而不是 _WidgetBase 来解决这个问题，因为 ContentPanes 知道如何调整自己的大小
