UI設計

• 1菠发、在PyCharm中添加External Tools中添加QtDesigner和PyUIC工具
  打開PyCharm>File>Settings>Tools>External Tools塑猖，單擊＋號添加工具角虫，出現(xiàn)下圖界面
  Name：自己定義
  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
  
  配置完成后會在Tools>External Tools 中顯示出來添加的工具
  
  External Tools

• 2、啟動QtDesigner胯陋，新建Main Window窗體
  啟動QtDesinger時将塑，確保電源選項高級設置中可切換動態(tài)顯卡全局設置為最佳性能，我的win10系統(tǒng)A卡顯卡切換成最大化性能將會導致無法啟動QtDesinger糕档，具體原因不清楚
  
  最佳性能
  
  Qt5.7中集成QtCreator、QtDesinger拌喉，二者都可以創(chuàng)建UI文件速那，設計界面，本文使用后者尿背，前者功能更強大端仰，有興趣的同學可以嘗試
  
  QtDesinger
  
  創(chuàng)建Main Window后，可以在左側看到具體的窗口插件田藐，Qt支持多種小插件荔烧，我還不怎么會使用。將插件拖到中間主體窗口汽久，調整布局即可完成UI設計鹤竭，右側顯示的是窗體屬性和信號槽設計區(qū)，使用Qt的信號槽機制可以完成多種邏輯操作景醇。Ctrl+r組合可以預覽界面臀稚。

  我自己設計的原始UI已經刪除，下圖是成品樣子

• 3三痰、UI設計完成后吧寺，直接使用PyUIC工具生成.py文件，在PyCharm中選中ui文件散劫，然后點擊運行PyUIC即可撮执，以下代碼自動生成。

添加圖標icon.addPixmap(QtGui.QPixmap(path), QtGui.QIcon.Normal, QtGui.QIcon.Off)
UI中加入六個PushButton組成第一排基本操作按鈕
一個Label提示輸入查詢單詞
另一個Label在最下方顯示統(tǒng)計單詞耗費的時間
UI右側是一個Text Browser顯示統(tǒng)計結果
最下方還有一個進度條ProgressBar
