GeckoFX 在winform中的简单应用

2023-10-04 20:49:22

1、创建winfrom工程-过程省略
2、在NuGet程序包管理器里添加GeckoFX相关引用DLL

3、在默认窗口中添加以下代码(默认窗口放了一个进度条两个操作跳转网页按钮和一个pannel)

GeckoWebBrowser browser;
public Form1()
{
InitializeComponent();
StartPosition = FormStartPosition.CenterScreen;
Xpcom.Initialize("Firefox");
browser = new GeckoWebBrowser();
this.browser.Name = "browser";
GeckoPreferences.User["gfx.font_rendering.graphite.enabled"] = true;//设置偏好：字体
GeckoPreferences.User["privacy.donottrackheader.enabled"] = true;//设置浏览器不被追踪
GeckoPreferences.User["intl.accept_languages"] = "zh-CN,zh;q=0.9,en;q=0.8";//不设置的话默认是英文区
//GeckoPreferences.User["permissions.default.image"] = 2; // block image 禁止加载图片
//GeckoPreferences.User["plugin.state.flash"] = 0; // bloack flash禁止加载flash
browser.CreateControl();
browser.NoDefaultContextMenu = true; //禁用右键菜单
browser.Dock = DockStyle.Fill;
panel1.Controls.Add(browser);
browser.ProgressChanged += Gecko_ProgressChanged;
browser.CreateWindow += Gecko_CreateWindow;//打开新窗口事件，全部设为在同一窗口打开
browser.DocumentCompleted += Gecko_DocumentCompleted;
//browser.UseHttpActivityObserver = true;//开启拦截请求
//browser.ObserveHttpModifyRequest += Browser_ObserveHttpModifyRequest;//拦截请求（在创建窗口之前就拦截。）
同时取消创建创建，在主窗口打开
browser.Navigate("http://www.baidu.com");
//browser.Navigate("http://127.0.0.1:8848/Html/login/login.html");
//browser.Navigate("https://www.bilibili.com/");
}
private void Gecko_DocumentCompleted(object sender, Gecko.Events.GeckoDocumentCompletedEventArgs e)
{
var executor = new Gecko.JQuery.JQueryExecutor(browser.Window); //先获取到jquery对象
executor.ExecuteJQuery("$('#a')"); //然后执行jquery的代码
using (AutoJSContext context = new AutoJSContext(browser.Window))
{
string result;
context.EvaluateScript("3 + 2;", out result);
context.EvaluateScript("'hello' + ' ' + 'world';", out result);
}
progressBar1.Value = 0;
}
//当前窗口跳转网址
private void Gecko_CreateWindow(object sender, GeckoCreateWindowEventArgs e)
{
try
{
browser.Navigate(e.Uri);
e.Cancel = true;
}
catch(Exception ex)
{
MessageBox.Show(ex.Message);
}
//e.InitialHeight = 500;
//e.InitialWidth = 500;
}
private void Gecko_ProgressChanged(object sender, GeckoProgressEventArgs e)
{
if (e.MaximumProgress == 0)
return;
var value = (int)Math.Min(100, (e.CurrentProgress * 100) / e.MaximumProgress);
if (value == 100)
return;
progressBar1.Value = value;
}
private void btn_GoBack_Click(object sender, EventArgs e)
{
browser.GoBack();
}
private void btn_GoPreview_Click(object sender, EventArgs e)
{
browser.GoForward();
}

4、效果

winform中带有默认布局器Dock可以对控件进行简单的布局，但是，在布局过程中，控件的布局效果与控件的添加顺序有着密切的关系。
先添加button1（left），再添加button2（fill）

先添加button1（fill），再添加button2（left）

可见布局效果存在巨大差异，这就使得Dock布局器只适合进行简单的布局，在这里介绍一种布局器，可以消除布局顺序对布局效果的影响，同时可以自己进行四角的设定。

代码如下：
