GeckoFX 在winform中的简单应用

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)

  1. GeckoWebBrowser browser;
  2. public Form1()
  3. {
  4. InitializeComponent();
  5. StartPosition = FormStartPosition.CenterScreen;
  6. Xpcom.Initialize("Firefox");
  7. browser = new GeckoWebBrowser();
  8. this.browser.Name = "browser";
  9. GeckoPreferences.User["gfx.font_rendering.graphite.enabled"] = true;//设置偏好：字体
  10. GeckoPreferences.User["privacy.donottrackheader.enabled"] = true;//设置浏览器不被追踪
  11. 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
  12. //GeckoPreferences.User["permissions.default.image"] = 2; // block image 禁止加载图片
  13. //GeckoPreferences.User["plugin.state.flash"] = 0; // bloack flash禁止加载flash
  14. browser.CreateControl();
  15. browser.NoDefaultContextMenu = true; //禁用右键菜单
  16. browser.Dock = DockStyle.Fill;
  17. panel1.Controls.Add(browser);
  18. browser.ProgressChanged += Gecko_ProgressChanged;
  19. browser.CreateWindow += Gecko_CreateWindow;//打开新窗口事件，全部设为在同一窗口打开
  20. browser.DocumentCompleted += Gecko_DocumentCompleted;
  21. //browser.UseHttpActivityObserver = true;//开启拦截请求
  22. //browser.ObserveHttpModifyRequest += Browser_ObserveHttpModifyRequest;//拦截请求（在创建窗口之前就拦截。）
  23. 同时取消创建创建，在主窗口打开
  24. browser.Navigate("http://www.baidu.com");
  25. //browser.Navigate("http://127.0.0.1:8848/Html/login/login.html");
  26. //browser.Navigate("https://www.bilibili.com/");
  27. }
  28. private void Gecko_DocumentCompleted(object sender, Gecko.Events.GeckoDocumentCompletedEventArgs e)
  29. {
  30. var executor = new Gecko.JQuery.JQueryExecutor(browser.Window); //先获取到jquery对象
  31. executor.ExecuteJQuery("$('#a')"); //然后执行jquery的代码
  32. using (AutoJSContext context = new AutoJSContext(browser.Window))
  33. {
  34. string result;
  35. context.EvaluateScript("3 + 2;", out result);
  36. context.EvaluateScript("'hello' + ' ' + 'world';", out result);
  37. }
  38. progressBar1.Value = 0;
  39. }
  40. //当前窗口跳转网址
  41. private void Gecko_CreateWindow(object sender, GeckoCreateWindowEventArgs e)
  42. {
  43. try
  44. {
  45. browser.Navigate(e.Uri);
  46. e.Cancel = true;
  47. }
  48. catch(Exception ex)
  49. {
  50. MessageBox.Show(ex.Message);
  51. }
  52. //e.InitialHeight = 500;
  53. //e.InitialWidth = 500;
  54. }
  55. private void Gecko_ProgressChanged(object sender, GeckoProgressEventArgs e)
  56. {
  57. if (e.MaximumProgress == 0)
  58. return;
  59.  
  60. var value = (int)Math.Min(100, (e.CurrentProgress * 100) / e.MaximumProgress);
  61. if (value == 100)
  62. return;
  63. progressBar1.Value = value;
  64. }
  65.  
  66. private void btn_GoBack_Click(object sender, EventArgs e)
  67. {
  68. browser.GoBack();
  69. }
  70.  
  71. private void btn_GoPreview_Click(object sender, EventArgs e)
  72. {
  73. browser.GoForward();
  74. }

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。
