UI设计

• 1、在PyCharm中添加External Tools中添加QtDesigner和PyUIC工具
  打开PyCharm>File>Settings>Tools>External Tools，单击＋号添加工具，出现下图界面
  Name：自己定义
  Group：External Tools
  Program：QtDesigner.exe所在位置
  Working directory：$ProjectFileDir$
  
  QtDesigner
  
  其他配置如上
  Parameters：-m PyQt5.uic.pyuic $FileName$ -o $FileNameWithoutExtension$.py
  
  PyUIC
  
  配置完成后会在Tools>External Tools 中显示出来添加的工具
  
  External Tools

• 2、启动QtDesigner，新建Main Window窗体
  启动QtDesinger时，确保电源选项高级设置中可切换动态显卡全局设置为最佳性能，我的win10系统A卡显卡切换成最大化性能将会导致无法启动QtDesinger，具体原因不清楚
  
  最佳性能
  
  Qt5.7中集成QtCreator、QtDesinger，二者都可以创建UI文件，设计界面，本文使用后者，前者功能更强大，有兴趣的同学可以尝试
  
  QtDesinger
  
  创建Main Window后，可以在左侧看到具体的窗口插件，Qt支持多种小插件，我还不怎么会使用。将插件拖到中间主体窗口，调整布局即可完成UI设计，右侧显示的是窗体属性和信号槽设计区，使用Qt的信号槽机制可以完成多种逻辑操作。Ctrl+r组合可以预览界面。

  我自己设计的原始UI已经删除，下图是成品样子

• 3、UI设计完成后，直接使用PyUIC工具生成.py文件，在PyCharm中选中ui文件，然后点击运行PyUIC即可，以下代码自动生成。

添加图标icon.addPixmap(QtGui.QPixmap(path), QtGui.QIcon.Normal, QtGui.QIcon.Off)
UI中加入六个PushButton组成第一排基本操作按钮
一个Label提示输入查询单词
另一个Label在最下方显示统计单词耗费的时间
UI右侧是一个Text Browser显示统计结果
最下方还有一个进度条ProgressBar
