CDHtmlDialog是一个好的选择吗(cef3/qtwebengine/react native/electron)
CDHtmlDialog总结:
适用于运行于windows环境下的工具；
比较适合于对旧的mfc工具进行轻量级的升级，
因为使用ie内核，所以最终程序比其他方案要小；此外还可以利用原有的大部分其他c、c++代码;
缺点运行环境比较特定，对用户本地ie有要求，如果用户ie版本不同会导致不同的显示效果和其他兼容性问题;
问题记录:
1.在CDHtmlDialog中使用mxGraph时发现,ie内核设置的ie11时，鼠标事件居然没反应，但是在ie中打开是正常的，对比了一下发现
msPointerEnabled,pointerEnabled 这两个值不同，
后来通过修改mxclient中的
IS_POINTER: false,//window.PointerEvent != null && !(navigator.appVersion.indexOf('Mac') > 0),
CDHtmlDialog中window.PointerEvent不为空但是msPointerEnabled和pointerEnabled却有问题，查了一些资料说是ie11废弃了pointerEnabled标识什么的，
直接设为false后，事件可以正常 响应了,不求甚解了;
2.由于需要加装本地文件，mxclient中相关修改如下:
mxXmlRequest.prototype.getStatus = function()
{
return 250;//this.request.status;
};
3.这段代码是对grapheditor添加stencils的测试修改:
this.addStencilPalette('ntest', 'ntest', dir + '/ntest.xml',
';whiteSpace=wrap;html=1;fillColor=#ffffff;strokeColor=#000000;strokeWidth=2');
4.navTrustedForActiveX是打开页面是允许activex控件:
//Navigate(L"jgraph.github.io/mxgraph/javascript/examples/grapheditor/www/index.html", navNoReadFromCache | navTrustedForActiveX);//www.baidu.com
Navigate(L"file://D:/dev/CDHtmlDlg-master/CDHtmlDlg-master/DHtml/2.html", navNoReadFromCache | navTrustedForActiveX);//
5.还遇到个问题访问外部链接报代理无响应问题，后来发现被软件阻断了，可以通过修改工程输出名通过,
后来基本都从本地加载这个问题就更不存在了;
6. 单独加载stencils的测试代码
