PyQt5 中的 QWebEngineView 中未绑定鼠标事件

  • 772

我在QWebEngineViewP中使用。yQt5无法on_click在打开的网页上绑定鼠标事件（类型的移动和事件）。这样的尝试不会带来成功。我究竟做错了什么？

import sys

from PyQt5 import QtCore
from PyQt5.QtWebEngineWidgets import QWebEngineView, QWebEngineSettings
from PyQt5.QtWidgets import QWidget
from PyQt5.QtWidgets import QStackedWidget
from PyQt5.QtCore import QModelIndex, QUrl

from PyQt5.QtWidgets import QBoxLayout
from PyQt5.QtWidgets import QApplication
from PyQt5.QtCore import Qt


class MouseFilter(QtCore.QObject):
    @QtCore.pyqtSlot()
    def eventFilter(self, obj, event):
        print(obj, event)
        return super().eventFilter(obj, event)


class Web(QWebEngineView):
    def load(self, url):
        self.setUrl(QUrl(url))
        self.page().settings().setAttribute(QWebEngineSettings.ShowScrollBars, False)


class Root(QWidget):
    def __init__(self):
        QWidget.__init__(self, flags=Qt.Widget)
        self.stack_widget = QStackedWidget(self)

        box = QBoxLayout(QBoxLayout.TopToBottom)
        web_browser = Web()
        web_browser.load("url")
        mouse_filter = MouseFilter()
        web_browser.installEventFilter(mouse_filter)

        self.stack_widget.addWidget(web_browser)
        box.addWidget(self.stack_widget)
        self.setLayout(box)


if __name__ == "__main__":
    app = QApplication(sys.argv)
    form = Root()
    form.show()
    exit(app.exec_())

    试试这样：

    import sys
from PyQt5.QtWidgets import QApplication, QBoxLayout, QStackedWidget, QWidget
from PyQt5.QtCore import Qt, QModelIndex, QUrl, QObject, pyqtSlot
from PyQt5.QtWebEngineWidgets import QWebEngineView, QWebEngineSettings


#class MouseFilter(QObject):
#    @pyqtSlot()
#    def eventFilter(self, obj, event):
#        print(obj, event)
#        return super().eventFilter(obj, event)


class Web(QWebEngineView):
    def load(self, url):
        self.setUrl(QUrl(url))
        self.page().settings().setAttribute(QWebEngineSettings.ShowScrollBars, False)


class Root(QWidget):
    def __init__(self):
        QWidget.__init__(self, flags=Qt.Widget)
        self.stack_widget = QStackedWidget(self)

        box = QBoxLayout(QBoxLayout.TopToBottom)
        web_browser = Web()
        web_browser.load("https://ru.stackoverflow.com/questions/1024513/%d0%9d%d0%b5-%d0%bf%d1%80%d0%b8%d0%b2%d1%8f%d0%b7%d1%8b%d0%b2%d0%b0%d1%8e%d1%82%d1%81%d1%8f-%d1%81%d0%be%d0%b1%d1%8b%d1%82%d0%b8%d1%8f-%d0%bc%d1%8b%d1%88%d0%b8-%d0%b2-qwebengineview-%d0%b2-pyqt5") #("url")

#        mouse_filter = MouseFilter()
#        web_browser.installEventFilter(mouse_filter)
        web_browser.installEventFilter(self)                      # +++

        self.stack_widget.addWidget(web_browser)

        box.addWidget(self.stack_widget)
        self.setLayout(box)

    @pyqtSlot()
    def eventFilter(self, obj, event):                            # +++
        print("\n{}\n{}".format(obj.title() , event))
        return super().eventFilter(obj, event)


if __name__ == "__main__":
    app = QApplication(sys.argv)
    form = Root()
    form.show()
    exit(app.exec_())
