基于PyQt或PySide开发图形化界面

python

之所以选择PyQt或PySide来开发图形界面,主要是因为Python和Qt的跨平台特性,Qt5甚至支持iOS和Android,并且开发相同的软件,Python的效率是极高的。

#!/usr/bin/env python

import sys

from PyQt4 import QtGui,QtCore

import httplib

from urllib import urlencode

import re

def out(text):

    p = re.compile(r'","')

    m = p.split(text)

    result=unicode(m[0][4:].decode('utf-8'))

    DS_Widget.setDS_TextEdit_text(result)

def dic():

    word=DS_Widget.getDS_LineEdit_text()

    text=urlencode({'text':word})

    h=httplib.HTTP('translate.google.cn')

    h.putrequest('GET', '/translate_a/t?client=t&hl=zh-CN&sl=en&tl=zh-CN&ie=UTF-8&oe=UTF-8&'+text)

    h.endheaders()

    h.getreply()

    f = h.getfile()

    lines = f.readlines()

    out(lines[0])

    f.close()

class DS_QWidget(QtGui.QWidget):

    def __init__(self):

        QtGui.QWidget.__init__(self)

        

        self.DS_LineEdit = QtGui.QLineEdit(self)  

        DS_SearchButton=QtGui.QPushButton('Search',self)

        self.DS_TextEdit = QtGui.QTextEdit(self)

        hbox = QtGui.QHBoxLayout()

        hbox.addWidget(self.DS_LineEdit)

        hbox.addWidget(DS_SearchButton)

        

        vbox = QtGui.QVBoxLayout(self)

        vbox.addLayout(hbox)

        vbox.addWidget(self.DS_TextEdit)

        

        self.resize(500, 300)

        self.setWindowTitle('Dictionary')

        self.connect(DS_SearchButton, QtCore.SIGNAL('clicked()'),dic)

        self.setLayout(vbox)

        

    def getDS_LineEdit_text(self):

        return self.DS_LineEdit.text()

    def setDS_TextEdit_text(self,text):

        self.DS_TextEdit.setText(text)

if __name__=="__main__":

    DS_APP = QtGui.QApplication(sys.argv)

    DS_Widget = DS_QWidget()

    DS_Widget.show()

    sys.exit(DS_APP.exec_())
