我正在使用 QWebEngine 在 Python PyQt5 中开发网络浏览器。一切正常，但是当有人点击空白的目标链接时，它显示为空白。我想在同一窗口中打开所有类型的链接。
如果我们右键单击并“跟随链接”，那么它会起作用，但是当我们简单地单击链接时，它就不起作用了。
_blank 目标链接也应该在同一个窗口中打开，而不是在 newtab 中打开

这是我的代码

最佳答案
诀窍是在 createWindow 中返回一个临时 QWebEnginePage，使用其 urlChanged 信号获取 url，在原始页面上设置该 url 并删除该临时 QWebEnginePage。
from PyQt5 import QtCore, QtWidgets, QtWebEngineWidgets
class WebEnginePage(QtWebEngineWidgets.QWebEnginePage):
def createWindow(self, _type):
page = WebEnginePage(self)
page.urlChanged.connect(self.on_url_changed)
return page
@QtCore.pyqtSlot(QtCore.QUrl)
def on_url_changed(self, url):
page = self.sender()
self.setUrl(url)
page.deleteLater()
class MainWindow(QtWidgets.QMainWindow):
def __init__(self, parent=None):
super(MainWindow, self).__init__(parent)
self.browser = QtWebEngineWidgets.QWebEngineView()
page = WebEnginePage(self.browser)
self.browser.setPage(page)
self.browser.load(QtCore.QUrl("https://www.w3schools.com/tags/tryit.asp?filename=tryhtml_a_target"))
self.setCentralWidget(self.browser)
if __name__ == '__main__':
import sys
app = QtWidgets.QApplication(sys.argv)
w = MainWindow()
w.showMaximized()
sys.exit(app.exec_())
关于python - 如何使用 QWebEngine 在同一窗口中打开任何链接(_blank)，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/54920726/
