Enabling Extensions on PyQt

Slim Shady

Hi, I've been trying to make a browser in PyQt and I would like to be able to get extensions for it.
Any tips are helpful!
Thanks in advance!
Here is the code:

import sys
from PyQt5.QtCore import *
from PyQt5.QtWidgets import *
from PyQt5.QtWebEngineWidgets import *


class MainWindow(QMainWindow):
    def __init__(self):
        super(MainWindow, self).__init__()
        self.browser = QWebEngineView()
        self.browser.setUrl(QUrl('http://google.com'))
        self.tab_wgt = QTabWidget()
        self.tab_wgt.addTab(self.browser, "home")
        self.tab_wgt.setTabsClosable(True)
        self.tab_wgt.tabCloseRequested.connect(lambda i: self.tab_wgt.removeTab(i))
        self.tab_wgt.currentChanged.connect(self.tab_changed)
        self.setCentralWidget(self.tab_wgt)
        self.showMaximized()

        # nav bar
        navbar = QToolBar()
        self.addToolBar(navbar)

        back_btn = QAction('Back', self)
        back_btn.triggered.connect(self.browser.back)
        navbar.addAction(back_btn)

        forward_btn = QAction('Forward', self)
        forward_btn.triggered.connect(self.browser.forward)
        navbar.addAction(forward_btn)

        reload_btn = QAction('Reload', self)
        reload_btn.triggered.connect(self.browser.reload)
        navbar.addAction(reload_btn)

        home_btn = QAction('Home', self)
        home_btn.triggered.connect(self.navigate_home)
        navbar.addAction(home_btn)

        new_btn = QAction('New Tab', self)
        new_btn.triggered.connect(self.newtab)
        navbar.addAction(new_btn)

        self.url_bar = QLineEdit()
        self.url_bar.returnPressed.connect(self.navigate_to_url)
        navbar.addWidget(self.url_bar)

        self.browser.urlChanged.connect(self.update_url)

    def navigate_home(self):
        self.browser.setUrl(QUrl('http://google.com'))

    def newtab(self):
        browser = QWebEngineView()
        self.tab_wgt.addTab(browser, "about:blank")
        self.tab_wgt.setCurrentWidget(browser)
        self.url_bar.setText("about:blank")
        browser.titleChanged.connect(self.update_title)
        browser.urlChanged.connect(self.update_url)

    def tab_changed(self, i):
        browser: QWebEngineView = self.tab_wgt.widget(i)
        if browser:
            text = browser.url().toString()
            if text:
                self.url_bar.setText(text)
            else:
                self.url_bar.setText("about:blank")

    def navigate_to_url(self):
        if "https://www." in self.url_bar.text():
            url = self.url_bar.text()
        else:
            url = "https://www." + self.url_bar.text()
        browser: QWebEngineView = self.tab_wgt.currentWidget()
        browser.setUrl(QUrl(url))

    def update_url(self, url):
        self.url_bar.setText(url.toString())

    def update_title(self, title):
        self.tab_wgt.setTabText(self.tab_wgt.currentIndex(), title)

class WebPage(QWebEnginePage):

    adblocker = Filter(open('easylist.txt', encoding="utf8"))

    def __init__(self, parent=None):
        super().__init__(parent)

    def acceptNavigationRequest(self, url,  _type, isMainFrame):

        urlString = url.toString()
        resp = False
        resp = WebPage.adblocker.match(url.toString())

        if resp:
            print("Blocking url --- "+url.toString())
            return False
        else:
            print("TYPE", _type)
            return True

        return QWebEnginePage.acceptNavigationRequest(self, url,  _type, isMainFrame)



app = QApplication(sys.argv)
QApplication.setApplicationName("Jeswwws")
window = MainWindow()
app.exec_()

@Slim-Shady If you mean chrome extensions then it is not possible because that does not implement chromium.

Slim Shady

@eyllanesc Not only Chrome extensions, any browser as long as it at least has any kind of ad blocker

eyllanesc

@Slim-Shady One thing is the adblock and another the extensions. An adblock can be implemented through extensions. On the other hand, extensions are popular so each browser implements it but it is not a technology that chromium implements. If you want to implement an ad blocker then check https://stackoverflow.com/questions/53330056/pyqt5-pyside2-adblock/53330741#53330741

@eyllanesc Thanks for that. I've checked it out but I don't know how to implement it with my code. Could you give me a hand, please?

eyllanesc

@Slim-Shady In my answer there is a complete example, I do not know what more help you are waiting for, bye. Try something and when something fails then just ask for help. Bye.

Slim Shady

Yes, I've seen the example, I just don't know how to make it run with my code. That's the "more help" that I need.

eyllanesc

@Slim-Shady I expect some effort on the part of the OP, if there is not then he does not ask for help but wants them to do their work so he must pay for it. So it's one thing to help and another to want them to work for you for free.

I'm sorry if that's how you see it, but I don't want you to do the work for me, I just need a little help.
