问题 In short, I'm making a discord bot that downloads the "World of the Day" picture in the website https://growtopiagame.com as D:\Kelbot/render.png and then sends the picture to the channel the command was called. However, it is not a static website and the URL is not in the source code, so I found a solution that uses PyQt5: import re import bs4 as bs import sys import urllib.request from PyQt5.QtWebEngineWidgets import QWebEnginePage from PyQt5.QtWidgets import QApplication from PyQt5.QtCore

问题 I have the following toy interface: from PyQt5 import QtWidgets, QtGui, QtCore class MainWindow(QtWidgets.QMainWindow): def __init__(self): super(MainWindow, self).__init__() w = QtWidgets.QWidget() layout = QtWidgets.QVBoxLayout() w.setLayout(layout) self.setCentralWidget(w) my_tree = QtWidgets.QTreeWidget() layout.addWidget(my_tree) alpha = QtWidgets.QTreeWidgetItem(my_tree, ['Alpha']) beta = QtWidgets.QTreeWidgetItem(my_tree, ['Beta']) alpha.addChild(QtWidgets.QTreeWidgetItem(['one']))

问题 I got the following code for Python GUI. I found I cannot update the data running in the main window to the pop-up window. In this example I use some random data to mimic the video frames and use a timer to update the data (the updateData() funciton). I want to see the green curve in the pop-up window changes... But I cannot find an effective way to pass the changing data to the pop-up window. Should I use the pyqtSignal() to define a custom signal? I read this page. Should I define the

问题 I am using PyQt5 QFileDialog.getOpenFileName . I am expecting the box to remain open until the "open" button is clicked. However, when I run the code on my Linux system, the dialog box closes immediately when the file name is clicked. On a Windows system, the box behaves as expected and remains open until the 'Open' button is clicked. The results are the same with or without the QFileDialog.DontUseNativeDialog option set. from PyQt5.QtWidgets import QApplication, QMainWindow, QPushButton,

问题 I am trying this sample code that I found which is really really good. I am also trying to figure out the same thing to find an item and scroll to it, but this time I wanted to match the the string which has the EXACT WORD "cat" . Example matches: cat tom cat dog and cat super cat To make it very simple I am just trying to match an exact word in a string.
