GeckoFX 在winform中的简单应用

桃扇骨 2022-02-15 07:58 204阅读 0赞

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

![d075047d1764c71b2224ef008ea4aa06.png][]

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

![221f6f176d669a637ce57ae039ed5e6e.png][]

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）

![51e9c1ae53bc346efd47b8d5d6e8670f.png][]

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。
