如何使用QWebEngine在同一窗口中打开任何链接(_blank) [英] how Make any link (_blank) open in same window using QWebEngine

问题描述

我正在使用QWebEngine在Python PyQt5中开发Web浏览器.一切正常，但是当有人单击空白的定向链接时，显示为空白.我想在同一窗口中打开所有类型的链接.

I'm developing a web browser in Python PyQt5 using QWebEngine. Everything is working fine but when someone click on the blank targeted link it shows blank. I want to open all type of links in same window.

如果我们右键单击并跟随链接"，则该链接有效，但当我们简单地单击链接时，该链接不起作用.

If we right click and "follow link" then it works but when we simply click on the link it doesn't working.

_空白目标链接也应在同一窗口中打开，而不要在newtab中打开

推荐答案

技巧是在createWindow中返回一个临时的QWebEnginePage，使用其urlChanged信号获取该url，在原始页面上设置该url，然后删除该临时QWebEnginePage.

The trick is to return a temporary QWebEnginePage in createWindow, use its urlChanged signal to get the url, set that url on the original page and delete that temporary 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_())
