如何从 PyQt qlineedit 对象获取输入？

Question

我想取用户在 lineedit 对象中输入的信息：

并将其存储在此变量中：

这是 lineedit 对象的 sn-p 代码：

self.nameLe = QtGui.QLineEdit(ContactCreator)
self.nameLe.setGeometry(QtCore.QRect(10, 60, 171, 20))
self.nameLe.setAutoFillBackground(False)
self.nameLe.setObjectName(_fromUtf8("name"))

完整代码在这里：http://pastebin.com/TGS9iNJH

Answer 1

name = str(self.nameLe.text())

你在找这个吗？

更新：

def addContact(self):
    self.name = str(self.nameLe.text())
    print self.name

我什至不知道为什么你到处都有全局变量和函数内部函数，而你在创建 gui 时调用 self.name = str(self.nameLe.text())。这不会做任何事情

编辑：完整的工作代码，注释了我不关心的 mysql 部分

# import sqlite3
from PyQt4 import QtCore, QtGui

# conn = sqlite3.connect('Contacts')
# c = conn.cursor()

# def tableCreate():
#     c.execute('CREATE TABLE ContactInfo(Name TEXT, Age INT, MobilePhone TEXT, Address TEXT)')

# name = ""
# age = int()
# mobilenum = ""
# Adr = ""

# def dataEntry():
#     c.execute('INSERT INTO CustomerInfo (Name, Age, MobilePhone, Address) VALUES (?,?,?,?)',
#         (Name, Age, MobilePhone, Adr))
#     conn.commit()
