Writing in Python 2.7 using pyQt 4.8.5: How may I update a Matplotlib widget in real time within pyQt? Currently I'm sampling data (random.gauss for now), appending this and plotting - you can see that I'm clearing the figure each time and re-plotting for each call: def getData(self): self.data = random.gauss(10,0.1) self.ValueTotal.append(self.data) self.updateData() def updateData(self): self.ui.graph.axes.clear() self.ui.graph.axes.hold(True) self.ui.graph.axes.plot(self.ValueTotal,'r-') self.ui.graph.axes.grid() self.ui.graph.draw() My GUI works though I think this is the wrong way to

准备环境 注：更简便的方法请参考此文： 定制 Kali Linux Live USB 的另一种方法 Kali Linux 自带了许多实用工具，将 ISO 刻录到U盘上做成的 Live USB 可以用在许多场合，比如无盘系统、公共电脑或者别人的电脑等。重启之后 Live 系统上的改动不会保存，并且 Live 磁盘空间比较小，不能临时装备过大的软件。所以定制自己的 Live 系统就很有必要了。本文讲述的是基于原有的 Live 文件系统定制，准备环境如下： Kali Linux 镜像：kali-linux-1.0.6-i386.iso U盘一只：大于4G，并格式化为 ext4 文件系统 制作环境：Kali Linux 定制 定制的基本思路就是解压原 ISO 镜像的 filesystem.squashfs，chroot 进去修改，将修改后的文件系统压缩，然后写入U盘。 首先，挂载 ISO: mkdir -p /mnt/kaliiso mount -o loop kali-linux-1.0.6-i386.iso /mnt/kaliiso 找到 filesystem.squashfs，解压（ apt-get install squashfs-tools 安装 unsquashfs）： unsquashfs /mnt/kaliiso/live/filesystem.squashfs /mnt

In my project I have a requirement to play live streaming video. I have seen many comments that "live streaming is supported only from 3.0" so that I have to use emulator 3.0. But it does not play. Can anybody help for me.. This is my code: String SrcPath="http://akamedia2.lsops.net/live/smil:cnbc_en.smil/playlist.m3u8"; myVideoView = new VideoView(this); myVideoView.setVideoURI(Uri.parse(SrcPath)); setContentView(myVideoView); myVideoView.setMediaController(new MediaController(this)); myVideoView.requestFocus(); myVideoView.setOnErrorListener(new OnErrorListener() { public boolean onError

I'm quite new to the on() method in jQuery but the time has come for me to need to use it. I've two functions for clicking on specific buttons. Each function works on any elements originally on the page but not on any dynamically added content (more of the same buttons). I understand I need to use the on() function after reading other answers on here and on Google but am having trouble still. Anyway, code: jQuery("ul#THEBUTTONS").on({ click: function(event){ event.preventDefault(); console.log("apaz clicked"); } }, "a.azaz"); jQuery("ul#THEBUTTONS").on({ click: function(event){ event

jQuery has a really handy event binder called live() which will add events to DOM elements on the fly (even for the elements that will be added later to the DOM). The problem is that it's only working on specific events ( listed here in documentation ). I really want to have live events for focus,blur and change which is not supported by live right now. Besides, if I can make live custom events, it will be big game changer for my app. Most of the code that I have right now is dedicated to rebinding old events (change, focus, and custom events for making items draggable or resizable) to new dom
