我试图用imap
库创建一个邮箱检查器,在没有GUI的情况下,使用Python、队列和多线程运行得很好。
但是当我尝试加入GUI时,我所做的每个函数都会使GUI冻结直到完成为止。
我尝试了许多来自各种文档(添加QThread,信号,光标等)和教程,但都对我无效。
有人能帮助我理解如何在运行函数时设置或附加文本到QTextEdit,因为它只能在完成后工作。
这是我的代码:
class Checker(QtCore.QThread):
signal = QtCore.pyqtSignal(object)
def __init__(self, lignesmailtocheck):
QtCore.QThread.__init__(self)
self.lignesmailtocheck = lignesmailtocheck
def run(self):
lignemailtocheck = self.lignesmailtocheck.strip()
maillo, passo = lignemailtocheck.split(":",1)
debmail, finmail = maillo.split("@",1)
setimap =["oultook.com:imap-mail.outlook.com", "gmail.com:imap.gmail.com"]
for lignesimaptocheck in sorted(setimap):
ligneimaptocheck = lignesimaptocheck.strip()
fai, imap = ligneimaptocheck.split(":",1)
if finmail == fai:
passo0 = passo.rstrip()
try :
mail = imaplib.IMAP4_SSL(imap)
mail.login(maillo, passo)
mailboxok = open("MailBoxOk.txt", "a+", encoding='utf-8', errors='ignore')
mailboxok.write(maillo+":"+passo+"\n")
mailboxok.close()
totaly = maillo+":"+passo0+":"+imap
print(maillo+":"+passo+"\n")
self.send_text.emit(totaly)
time.sleep(1)
except imaplib.IMAP4.error:
print ("LOGIN FAILED!!! ")
class Ui_Form(object):
def setupUi(self, Form):
Form.setObjectName("Form")
Form.resize(400, 300)
self.pushButton = QtWidgets.QPushButton(Form)
self.pushButton.setGeometry(QtCore.QRect(150, 210, 75, 23))
self.pushButton.setObjectName("pushButton")
self.pushButton.clicked.connect(self.gogogo)
self.openliste = QtWidgets.QToolButton(Form)
self.openliste.setGeometry(QtCore.QRect(40, 110, 71, 21))
self.openliste.setObjectName("openliste")
self.textEdit = QtWidgets.QTextEdit(Form)
self.textEdit.setGeometry(QtCore.QRect(170, 50, 201, 121))
self.textEdit.setObjectName("textEdit")
self.progressBar = QtWidgets.QProgressBar(Form)
self.progressBar.setGeometry(QtCore.QRect(10, 260, 381, 23))
self.progressBar.setValue(0)
self.progressBar.setObjectName("progressBar")
self.retranslateUi(Form)
QtCore.QMetaObject.connectSlotsByName(Form)
def retranslateUi(self, Form):
_translate = QtCore.QCoreApplication.translate
Form.setWindowTitle(_translate("Form", "Form"))
self.pushButton.setText(_translate("Form", "PushButton"))
self.openliste.setText(_translate("Form", "..."))
def gogogo(self):
mailtocheck = open('File/toCheck.txt', 'r', encoding='utf-8', errors='ignore').readlines()
setmailtocheck = set(mailtocheck)
for lignesmailtocheck in sorted(setmailtocheck):
checker = Checker(lignesmailtocheck)
thread = QThread()
checker.moveToThread(thread)
# connections after move so cross-thread:
thread.started.connect(checker.run)
checker.signal.connect(self.checkedok)
thread.start()
def checkedok(self, data):
print(data)
self.textEdit.append(data)
if __name__ == "__main__":
app = QtWidgets.QApplication(sys.argv)
Form = QtWidgets.QWidget()
ui = Ui_Form()
ui.setupUi(Form)
Form.show()
sys.exit(app.exec_())
