這篇文章主要為大家詳細(xì)介紹了PyQt5實(shí)現(xiàn)簡(jiǎn)易電子詞典，具有一定的參考價(jià)值，感興趣的小伙伴們可以參考一下

PyQt5是python中一個(gè)非常實(shí)用的GUI編程模塊，功能十分強(qiáng)大。剛剛學(xué)完了Pyqt的編程，就迫不及待的寫(xiě)出了一個(gè)電子詞典GUI程序。整個(gè)程序使用qt Desiner把整個(gè)gui界面做好，槽函數(shù)則自己寫(xiě)好的。電子詞典實(shí)現(xiàn)了查詢單詞，查詢歷史記錄，收藏和查看單詞本的功能，另外為了是程序更加炫酷，還添加了一個(gè)啟動(dòng)界面。具體代碼如下：

第一個(gè)為主程序代碼，主要實(shí)現(xiàn)槽函數(shù)功能。

from PyQt5.QtCore import pyqtSlot
from PyQt5.QtWidgets import QMainWindow

 @pyqtSlot()
 def on_pushButton_clicked(self):
  """

  """
  # 單詞查詢,需要先有一個(gè)'dict.txt'文件,其中有大量的英文單詞和注釋
  # 此處也可以先把'dict.txt'插入數(shù)據(jù)庫(kù),歷史記錄和單詞本的插入和查詢都可以直接操作數(shù)據(jù)庫(kù)
  # 不過(guò)數(shù)據(jù)庫(kù)需要事先安裝數(shù)據(jù)庫(kù),并建立相應(yīng)的表,不好打包,不太方便

     file.write(msg)
     file.write('\n')
     file.close()

第二個(gè)程序代碼，主要實(shí)現(xiàn)整體的GUI界面的構(gòu)建（使用Qtdesiner可以極大的簡(jiǎn)化工作量，強(qiáng)烈推薦）

textBrowser中的內(nèi)容可以以html的格式顯示出來(lái)，所有其中的文件的顯示可以按照自己的喜好來(lái)設(shè)計(jì)。

以上就是本文的全部?jī)?nèi)容，希望對(duì)大家的學(xué)習(xí)有所幫助，也希望大家多多支持腳本之家。
