问题 I am trying to create a floating browser for youtube and other media. I found some old examples of adblock like for PyQt4/PySide but now they are deprecated and I can't translate them to PySide2 QWebEngineView. Any ideas of how insert the adblock inside a QWebEngineView? Older version link How would you adblock using Python? 回答1: To filter urls, a QWebEngineUrlRequestInterceptor must be implemented, and if you want to block the url you must call the block (True) function to the

How to embed basic HTML page using Qt?

由 ╄→尐↘猪︶ㄣ 提交于 2021-01-28 07:16:25
问题 I am using PySide2.QtWebEngineWidgets.QWebEngineView() to setHtml on it to show a basic page like below. This html file works fine in a browser because it has all the files in the same folder relative to the html file. Once I setHtml to the below file, I get this exception: Qt Error: Uncaught ReferenceError: require is not defined Is this related to Qt not finding the relative files unlike a regular browser? Or is there something else I should be doing? Or is QWebEngineView not advanced

问题 I'm trying to display some Plot.ly or Plot.ly Dash plots ( I haven't settled on using one or the other, so I'm experimenting with both right now) in a PyQt5 GUI using QWebEngineView. This doesn't work for any plots larger than 2MB due to some Chromium-level hardcoded restriction. I found one similar question that is pretty much identical in terms of our needs. It looks like the OP actually found an answer, but unfortunately for me, they didn't post an example of working code or explain what

How to download csv file with QWebEngineView and QUrl

由 廉价感情. 提交于 2021-01-24 09:11:13
问题 I'm building a program which uses QWebEngineView and QUrl to display a website in my PyQt5 app (running on Windows 10). However, I now want to be able to download a CSV file from the same website, but being a noob I can't seem to figure out how. I'm familiar with using requests , urllib.request , urllib3 , etc. for downloading files, but for this, I specifically want to do it with the QWebEngineView, as the user will have authenticated the request previously in the pyqt5 window.

问题 I am trying to print a report from within my application, which involves both text and tables. Since QTextDocument won't be sufficient, I've decided to go with QWebEngineView and more sophisticated HTML/CSS which is not supported by the Qt rich text engine. I am able to create a PDF from the view, however I am having some general misconceptions, because at times its crashing, and also printing instead of PDF creation crashes. Here is my attempts: Approach 1: PDF creation This is the only
