问题 Am having a qlineedit where a user types a verification code. I want to be able to space these numbers automatically every after 5 characters just like it is when activating windows where dashes are automatically added. For example 12345 67890 12345 67890 回答1: If the number of digits is fixed the best option is to use setInputMask(), in your case: if __name__ == '__main__': app = QApplication(sys.argv) le = QLineEdit() le.setInputMask(("ddddd "*4)[:-1]) le.show() sys.exit(app.exec_()) In the

问题 Is it possible to have Altair or Vega(-Lite) render to a PyQt widget, similar to Matplotlib supporting multiple backends? I know I can use a Qt WebView widget to render a web page with Vega-embed, but I want to prevent the overhead of having to serve this, even if locally. 回答1: The best option to visualize a plot with Altair is to use QWebEngineView since altair what is to create javascript code based on the instructions you set. IMHO the best solution is to obtain the html of the chart and

问题 I'm trying to make an app that receives UDP data and shows the data in a list view using python (PyQt5). When I start the receiver, the app gets stuck and does not respond. How can I fix this? See code below. import sys import os import socket from PyQt5.QtGui import * from PyQt5.QtWidgets import * class udpReceiverApp(): app = QApplication (sys.argv) x = 1 ip = "192.168.1.4" port =515 server_start = True sock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM) sock.bind((ip,port)) def __init_

问题 I would like to add various widgets to various cells in a Table Widget, and I would like to trigger commands when those widgets' values are changed. I can get the widgets into the table as desired, but I'm having problems connecting signals so that I know which widget has generated the signal. Below is a simple example explaining the problem, using just checkboxes: from PyQt5 import QtWidgets, QtGui, QtCore class Main(QtWidgets.QMainWindow): def __init__(self, parent=None): super().__init__

问题 I would like to play a certain part of a video, for example, play a video from second 30 to second 33 using PyQt5. I am using the Qmultimedia widget. This is how my player code looks. Is there a way to start and end at a certain position? I've been manually clipping the video into subclips and just playing those subclips instead but that's very time consuming. Thank you! self.player = QtMultimedia.QMediaPlayer(None, QtMultimedia.QMediaPlayer.VideoSurface) file = QtCore.QDir.current().filePath
