PyQt5-如何在QTextBrowser中显示可单击的超链接
问题描述:
我用PyQt5创建了一个GUI.现在,我想将超链接添加到 QTextBrowser
.不幸的是,这些文本不可单击,而是显示为普通文本,我很难找出原因.
I have created a GUI with PyQt5. Now I would like to add hyperlinks to a QTextBrowser
. Unfortunately, the texts are not clickable but instead displayed as normal text and I have a hard time finding out why.
import sys
from PyQt5.QtWidgets import QApplication, QWidget, QVBoxLayout, QTextBrowser
class MainWindow(QWidget):
def __init__(self):
super().__init__()
self.text_browser = QTextBrowser()
self.text_browser.setOpenExternalLinks(True)
self.text_browser.setReadOnly(True)
self.text_browser.append("<a href=https://google.com/>Google</a>")
self.text_browser.append("<a href=https://github.com/>Github</a>")
layout = QVBoxLayout()
layout.addWidget(self.text_browser)
self.setLayout(layout)
if __name__ == '__main__':
app = QApplication(sys.argv)
window = MainWindow()
window.show()
app.exec_()
没有链接的GUI
答
与标准Web浏览器相比,Qt使用的HTML解析器是基本的,因此首选标准语法.
The HTML parser used by Qt is elementary compared to those of a standard web browser, so a more standard syntax is preferred.
尽管可以就是否存在bug进行辩论,但最好在HTML属性周围使用引号.
While it's open to debate whether this is a bug or not, it's always better to use quotes around HTML attributes.
self.text_browser.append("<a href='https://google.com/'>Google</a>")
self.text_browser.append("<a href='https://github.com/'>Github</a>")
注意:默认情况下,QTextBrowser只读,因此无需设置该选项.
