问题 I'm a beginner in PyQt and I have an image known as add.gif . I need to put this image in a QPushButton but I don't know how. 回答1: Example: from PyQt4 import QtGui, QtCore class Window(QtGui.QWidget): def __init__(self): QtGui.QWidget.__init__(self) self.button = QtGui.QPushButton('', self) self.button.clicked.connect(self.handleButton) self.button.setIcon(QtGui.QIcon('myImage.jpg')) self.button.setIconSize(QtCore.QSize(24,24)) layout = QtGui.QVBoxLayout(self) layout.addWidget(self.button)

爬虫+pyqt5 打造属于自己的抖音视频下载器

前言：最近一段时间在家经常会用抖音来度过娱乐时间，经常会直接通过抖音软件向好友分享视频。自己无聊至极就花了一上午的时间做了一个PC端的抖音视频下载器。 郑重申明：该文章介绍的技术仅供用于学习，不可恶意攻击抖音网站。对抖音服务器造成的任何损失，后果自负。 具体的视频在如下链接地址： douyin.mp4 需要用到的工具： **1、Chrome浏览器（如Chrome，装了httpwatch的IE浏览器等）+ charles（个人比较喜欢的抓包工具） 2. Pycharm（任何一个自己熟悉的编译器即可） 其实在该软件的编写过程中，个人认为是分为两个部分。 1.视频抓包地址的分析以及获取 2.界面逻辑代码的编写 一、视频地址的分析与抓取 1.我们先在自己的手机端的抖音软件上选取一个自己像下载的视频，并通过连接分享给别人 2.我们在Chrome上面输入上文的链接，并点击右键–设置–network 。再单独打开charles软件。点击回车键开始获取内容 我们会发现我们在浏览器初始输入的地址变成了下方的地址。其实这里涉及爬虫的一个重定向问题（ 重定向(Redirect)就是通过各种方法将各种网络请求重新定个方向转到其它位置（如：网页重定向、域名的重定向、路由选择的变化也是对数据报文经由路径的一种重定向）。） 在这里的流程其实就是：先跳转到我填写的网址—根据当前网址的重定向信息获取到定向后的位置

multiprocessing - child process constantly sending back results and keeps running

问题 Is it possible to have a few child processes running some calculations, then send the result to main process (e.g. update PyQt ui), but the processes are still running, after a while they send back data and update ui again? With multiprocessing.queue, it seems like the data can only be sent back after process is terminated. So I wonder whether this case is possible or not. 回答1: I don't know what you mean by "With multiprocessing.queue, it seems like the data can only be sent back after

multiprocessing manager.list inheritance with a pyqt5 signal

由 霸气de小男生 提交于 2020-07-23 08:00:06
问题 I have a shared list between processors. this list, when change size from different processsor, it runs a function in the main processor to modify a QWidget. Since I can't add somthing to a QWidget from another process, I need the slot function to be run in the main processor. Therefore, I need a a slot function activated when a list changed size. @musicamante did a very nice job in creating a list subclass, but it is not working with manager().list() . I tried to inherit to multiprocessing
