本篇文章為大家展示了使用PyQt5怎么實現簡易電子詞典,內容簡明扼要并且容易理解,絕對能使你眼前一亮,通過這篇文章的詳細介紹希望你能有所收獲。
第一個為主程序代碼,主要實現槽函數功能。
from PyQt5.QtCore import pyqtSlot from PyQt5.QtWidgets import QMainWindow from PyQt5 import QtWidgets from Ui_E_Dict_Main import Ui_E_Dictory from PyQt5.QtWidgets import * from PyQt5.QtGui import * from PyQt5.QtCore import * import time, re # 槽函數代碼,運行程序需要運行本文件 class MainWindow(QMainWindow, Ui_E_Dictory): """ Class documentation goes here. """ def __init__(self, parent=None): """ Constructor @param parent reference to the parent widget @type QWidget """ super(MainWindow, self).__init__(parent) self.setupUi(self) # 啟動時休眠1秒 time.sleep(1) # 按鈕1 查找單詞,把單詞顯示在textBrowser的同時,插入歷史記錄 @pyqtSlot() def on_pushButton_clicked(self): """ Slot documentation goes here. """ # 單詞查詢,需要先有一個'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'插入數據庫,歷史記錄和單詞本的插入和查詢都可以直接操作數據庫 # 不過數據庫需要事先安裝數據庫,并建立相應的表,不好打包,不太方便 word=self.lineEdit.text() f=open('dict.txt', 'r') for line in f: # 對字典文件的數據進行分析,拆解為適合顯示的格式 l = re.split('[ ]+',line) if l[0]==word: interpret=' '.join(l[1:]) data='%s\n %s'%(l[0], interpret) # interpret='%s: %s'%(l[0],' '.join(l[1:])) self.textBrowser.setText(data) # 當地時間 t1=time.localtime() t2=time.asctime(t1) #self.lineEdit.setText("")#lineEdit輸入后清零,可要可不要 try: # 把所查詢單詞插入歷史記錄中, #'a'以只寫文件打開一個文件,如果有原文件則追加到文件末尾 file=open('history.txt', 'at') msg='%s %s'%(word, t2) file.write(msg) file.write('\n') file.close() except Exception as e: print(e) f.close() @pyqtSlot() def on_pushButton_2_clicked(self): """ Slot documentation goes here.

第二個程序代碼,主要實現整體的GUI界面的構建(使用Qtdesiner可以極大的簡化工作量,強烈推薦)
