Github Desktop1:git的优点和github desktop的简单使用

多人合作一个项目,一定要把代码放到一个地方,并随时同步自己本地的和公共的代码。我们也曾这么做,租用一台服务器,修改完本地的代码就复制到服务器上,而开始编写前把服务器上的复制到本地。然而这样做有以下缺点: 1.麻烦。就算用ftp软件同步文件,选择文件并复制也很繁琐。 2.缺乏更新信息的交流。对代码进行修改,却不说明这次修改了哪些部分,没有更新日志,这将造成开发者对项目的严重误读,而传统的更新日志方式往往只是在社交软件进行简单的口头说明,不够严谨、丰富。 3.没有版本还原机制。假如一个人不幸地把错误的文件复制到服务器上,在错误被发现之前,很可能被传播给更多人。 4.存在版本更新冲突。假如A和B都修改了同一文件,则同步代码至服务器后,服务器上只会有最后同步者的更新,两人对此却浑然不觉。这实际上也是缺少更新日志造成的。 git本身只有控制台版本,很难用。github desktop(以下简称desktop)是git的图形化界面版本,正好解决了上述问题: 1.项目在本地更新后,可一键同步到代码仓库,也可一键将代码仓库同步到本地。 2.更改文件,或者增加删除文件都可以(实际上是必须)附上更新说明,既有简述又有详细说明。还会保存整个项目的更新日志。 3.会保存文件的过去版本,因此可撤销自己的,甚至是他人的改动,减轻了发生错误的影响。 4.可一键检查公共仓库有无更新

问题 What is the difference between a "normal" Java desktop application (with AWT or Swing), and a Java application built with JavaFX? What are the advantages and disadvantages of each? 回答1: I think what you are asking is what are the pros and cons of building a JavaFX desktop application vs a Java Swing desktop application. After experimenting with both I can point out a few differences: Java Swing Pros: Better visual designer and IDE support More full featured set of controls Good for building

问题 I'd like to draw to the desktop wallpaper area with directX 9 in particular. Under the icons and text above the wallpaper. Similar to Okozo or one of VLC's modes, or Dreamscene. So there's a lot of similar questions to this but no working examples or tutorials.This A simmilar question but different approach seems pretty useful. A few years ago I was searching and found this site and code. It's perfect aside from one big issue the icon text gets blocky even with alpha blending. I tried a few

Is there a “best” or most popular database for standalone Java app?

问题 Is there a "best" or more popular database for standalone Java app? I'm currently writing by hand, but I would like to know what is commonly done, if there is something that is commonly done. update: talking about small app (may grow, but its small for now) 回答1: I would suggest using something like SQLite with SQLiteJDBC. It also sounds like HyperSQL and Derby (which ships with certain Java versions) are popular choices. 回答2: Java 6 ships with Derby (renamed JavaDB). It can be used in memory

What are the best practices for internationalizing a Java Swing desktop application?

老子叫甜甜 提交于 2019-12-30 02:30:05
问题 I'm sure there are a lot of methods, but what's the recommended way to do this that has the least amount of impact to your code? The obvious is that you create properties files, but how do you swap the values in the rendering? In J2EE you always just re-render the whole page so it's easy. But in Swing apps, do you just add the code for the .getProperty() in the paintComponent(Graphics g) method? If that's the case, doesn't it seem heavy since now you'll have to override this method everywhere

  平时都会用到,所以学习下没有坏处,但是一直没有找到系统的学习方法,所以自己就零零散散地记录下,以便自己以后查阅! 输入【cd..】,可以返回到父文件夹: 【注】我猜"cd"的全称应该是"change directory",就是“改变目录”的意思! 【注】"cd/"或是"cd\"都是返回根目录的命令! 输入【cd /d F:/Desktop】,可以跳转到 F:/Desktop 文件夹(斜杠正反均可): 【注】cd为“改变目录”的意思,/d则为“目录是”,然后后面写上具体的目录即可! 输入【start "" "F:\360云盘"】,可以打开 F:\360云盘 文件夹: 输入【start "" "F:\Desktop\TEMP\1257.zip"】,可以打开 F:\Desktop\TEMP 文件夹下面的 1257.zip 文件: 直接将写入的内容在记事本上面编辑,然后存成 .bat 文件即可以运行: 如何让运行 .bat 文件的时候没有一闪的方法: 参考: http://zhidao.baidu.com/question/269741610.html 使用CMD命令复制系统隐藏文件 操作步骤: 1) 我的电脑--工具--文件夹选项--查看--隐藏受保护的操作系统文件(推荐)【去掉勾】 2) 开始--运行--输入CMD,进入dos窗口。 3) 然后在DOS窗口里的闪烁光标处,输入

问题 I want to make a responsive layout with twitter's bootstrap v2, with a column and a map. The idea is to build a UI like that from maps.google.com, but using a responsive design with bootstrap2.
