1、d出层的触摸优先级, *** 作与显示相一致
2、定制按钮个数
3、窗口的大小可变
4、回调函数的实现方案
5、onEnter动态创建d出层

//ContentSize是可选的设置,可以不设置,如果设置则把它当做9图缩放
//popup->setContentSize(CCSizeMake(400,360));
popup->setTitle("Message");
popup->setContentText("Mostpeople... blunder round this city.",20,50,150);
//设置回调函数,回调传回一个CCNode以获取tag判断点击的按钮
//这只是作为一种封装实现,如果使用delegate那就能够更灵活的控制参数了
popup->setCallBackFunc(this,callfuncN_selector(HelloWorld::buttonCallBack));
//添加按钮,设置图片、文字,tag信息
popup->addbutton("button.png","button.png","Ok",0);
popup->addbutton("button.png","Cancel",1);
this->addChild(popup);
测试截图:
这样,对话框的基本模型就完成了,它实现了以下功能:
一个可以d出的对话框实现 模态窗口的实现(需要逻辑的控制) 多按钮的支持,位置自适应,提供回调函数 提供标题和内容设置 支持 九图,控制适应d出框大小
