在跨平台Gtk应用程序中嵌入Web浏览器

Question

我需要在一个Gtk Widget中嵌入一个非常简单的浏览器(可以解析HTML和JS Ext),希望在gtkmm中.我查看了gtkmozembed,但是c ++包装器已经过时了,所以我试着用C语言编写它,但我已经承诺使用Gtk + 3.0,并且gtkmozembed不适用于Gtk + 3.0.有没有办法只扩展Gtk :: Widget并在其中放置一个gecko解析器？无法找到任何壁虎文档,我一直被重定向到gtkmozembed.

任何想法/建议将不胜感激.

编辑:@Mark我尝试使用Webkitgtk后,得到以下输出,应用程序崩溃.

如果我的记忆能为我服务,gtkmozembed也不会使用新版本的Gecko.您正在寻找的是WebkitGTK,至少如果您没有专门与Gecko绑定.

作为@ptomato 答案的附录。WebKitGTK 是正确的选择。我不知道它的 gtkmm/C++ 包装器，但我目前在 gtkmm 项目中非常成功地使用它（幸运的是，gtkmm/C++ 允许您很容易地在 C gtk 中混合）：

WebKitWebView* pWebKitView = WEBKIT_WEB_VIEW (webkit_web_view_new ());
gtk_container_add (GTK_CONTAINER (pSomeContainer->gobj()), GTK_WIDGET (pWebKitView));

然后你就走...
