問題描述
我需要使用 pyQt5 打開一個 URL.該頁面有幾個鏈接可以打開一個新窗口.pyQt5 為 URL 打開一個窗口,但在單擊應該打開一個新窗口的鏈接后不執行任何操作.PS我正在使用pyQt5.6
I need to open an URL using pyQt5. The page has several links that open a new window. pyQt5 opens a windows for the URL but does not do anything after clicking on a link that should open a new window. P.S I'm using pyQt5.6
我已經在 Linux centOs 上嘗試過,但沒有任何效果.
I have tried it on Linux centOs but nothing works.
from PyQt5.QtCore import QUrl
from PyQt5.QtGui import QDesktopServices
from PyQt5.QtWidgets import QApplication
from PyQt5.QtWebEngineWidgets import QWebEngineView, QWebEnginePage
class WebEnginePage(QWebEnginePage):
def acceptNavigationRequest(self, url, _type, isMainFrame):
if _type == QWebEnginePage.NavigationTypeLinkClicked:
return True
return QWebEnginePage.acceptNavigationRequest(self, url, _type, isMainFrame)
class HtmlView(QWebEngineView):
def __init__(self, *args, **kwargs):
QWebEngineView.__init__(self, *args, **kwargs)
self.setPage(WebEnginePage(self))
if __name__ == '__main__':
import sys
app = QApplication(sys.argv)
w = HtmlView()
w.load(QUrl("https://gmail.com"));
w.show()
sys.exit(app.exec_())
我希望它會在任何網頁上單擊 target='_blank' 時打開一個新窗口.
I expect it to open a new window on click of target='_blank' on any webpage.
推薦答案
你必須重寫 createWindow 方法并返回一個 QWebEngineView,但是為了不破壞對象,它必須是另一個窗口的子窗口或者是具有更長生命周期的容器.
You have to override the createWindow method and return a QWebEngineView, but for the object not to be distruded it must be the child of another window or be part of a container that has a longer life cycle.
from PyQt5 import QtCore, QtGui, QtWidgets, QtWebEngineWidgets
class WebEnginePage(QtWebEngineWidgets.QWebEnginePage):
def acceptNavigationRequest(self, url, _type, isMainFrame):
if _type == QtWebEngineWidgets.QWebEnginePage.NavigationTypeLinkClicked:
return True
return super(WebEnginePage, self).acceptNavigationRequest(url, _type, isMainFrame)
class HtmlView(QtWebEngineWidgets.QWebEngineView):
def __init__(self, windows, *args, **kwargs):
super(HtmlView, self).__init__(*args, **kwargs)
self.setPage(WebEnginePage(self))
self._windows = windows
self._windows.append(self)
def createWindow(self, _type):
if QtWebEngineWidgets.QWebEnginePage.WebBrowserTab:
v = HtmlView(self._windows)
v.resize(640, 480)
v.show()
return v
if __name__ == '__main__':
import sys
app = QtWidgets.QApplication(sys.argv)
windows = []
w = HtmlView(windows)
w.load(QtCore.QUrl("https://gmail.com"));
w.show()
sys.exit(app.exec_())
