问题 I wanted to set QCullFace to FrontAndBack and that is why I wrote this: from PySide2.Qt3DRender import Qt3DRender cull_face = Qt3DRender.QCullFace() cull_face.setMode(Qt3DRender.QCullFace.FrontAndBack) render_pass = Qt3DRender.QRenderPass() render_pass.addRenderState(cull_face) The code above should set CullFace globally. But it does not. What did I do wrong? 回答1: I assume that the python binding does not change how Qt works in C++. So you probably have a Qt3DWindow somewhere (unless you

问题 I'm using Pyside2, python 3.8, Qt 5. I have a QTableView with a QAbstractTableModel to it. I have a Combobox (ComboBoxColumns) that lists all my columns headers, and a second Combobox (ComboBoxValues) that lists all the distinct values in the column that is selected in the ComboBoxColumns. My two ComboBoxs are connected to two different QStringListModel. What I want is to only keep the rows where the Value(row, ComboboxColumns.currentIndex) == ComboBoxValues.currentIndex. I'm trying to

问题 I'm trying to make an application that uses QML QCharts to visualize data. The program is crashing at startup before a window even appears. I tried on both macOS and Windows 10 with the same results. I have included a minimally working example below. main.py : import sys from PySide2.QtGui import QGuiApplication from PySide2.QtQml import QQmlApplicationEngine from PySide2.QtCore import QUrl import qml_rc if __name__ == "__main__": app = QGuiApplication(sys.argv) engine = QQmlApplicationEngine

问题 I am trying to convert an existing PySide2/QtWidgets application to PySide2/QML. I am trying to get a list of custom objects from a Python service call via a QML MouseArea click. I currently have a main script ( main.py ) that launches a QQuickView containing my QML (contained in main.qml ). It also registers a custom type for my model ( Role , defined in role.py ) and exposes an instance of my service class (contained in mock_role_service.py ) to the view's root context. My QML displays

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

问题 I'm currently working on creating a QML Calendar that will ideally display events from a Google calendar. This is an example of what I'd like to emulate in python: https://doc.qt.io/qt-5.9/qtquickcontrols-calendar-example.html Right now, a python file is taking dates and event summaries from the Google Calendar API and returning them as a dictionary (the tenevents variable in the python code) of {date: event summary}. I have a very simple QML window displaying a calendar and a rectangle. I

问题 I am working on Ubuntu 20.04 with Python3 and PySide2, Qt is version 5. I wrote this simple Python script in order to test the ability to save webcam video for a larger project I will later work on. Basically, I would like that this demo script at first and simply displays the stream coming from the camera, in a widget I named "frame", but it seems I am missing something, because a message gets printed in the terminal: Starting camera without viewfinder available I made the GUI within
