如何在 QTextBrowser 中显示可点击的超链接
How to display a clickable hyperlink in QTextBrowser
我创建了一个 GUI，您可以在其中输入内容，在搜索栏中，它会直接进入 duckduckgo 并搜索输入的元素，然后在 [= 中打印所有 hyperlinks 11=]。但是 link 是不可点击的。我不知道怎么做 clickable.I 如果你们能帮助我，我将不胜感激。
主要功能是input_value，我写了后台进程。这是我的代码：

self.centralwidget.setObjectName("centralwidget")
self.searchforpoi = QtWidgets.QPushButton(self.centralwidget)
self.searchforpoi.setGeometry(QtCore.QRect(730, 20, 111, 34))

编辑：- 单击 link 时，它应该打开一个默认的 Web 浏览器并且 QTextBrowser 应该保留所有其他 links。
消耗大量时间的任务必须在辅助线程中执行并通过信号发送信息，另一方面，将 url 作为文本传递不会使它们可点击，你应该做的是使用 "href"。为了不改变页面，QTextBrowser（不删除链接）必须打开属性 OpenLinks 为False。要在 OS 默认浏览器中打开 url，您必须使用 QDesktopServices.openUrl():
