对pyqt5多线程正确的开启姿势详解

如下所示：

# -*- coding: utf-8 -*-

import sys
from pyqt5.qtcore import qthread, pyqtsignal
from pyqt5.qtwidgets import qapplication, qmainwindow, qwidget, qmessagebox, \
  qpushbutton, qlineedit, qlabel, qtooltip, qcombobox, qtextedit


class mybeautifulclass(qmainwindow):
  def __init__(self):
    super(mybeautifulclass, self).__init__()
    self.init_ui()

  def init_ui(self):
    self.resize(1000, 800)
    self.setwindowtitle('demo of pyqt5 qthread')
    self.btn_1 = qpushbutton('start', self)
    self.btn_1.setgeometry(100, 100, 100, 50)
    self.btn_1.clicked.connect(self.slot_btn_1)
    self.linedit_2 = qlineedit(self)
    self.linedit_2.setgeometry(100, 400, 300, 50)

  def slot_btn_1(self):
    self.mbt = mybeautifulthread()
    self.mbt.trigger.connect(self.slot_thread)
    self.mbt.start()

  def say_love(self):
    print('say love')

  def slot_thread(self, msg_1, msg_2):
    self.linedit_2.settext(msg_1 + msg_2)


class mybeautifulthread(qthread):
  trigger = pyqtsignal(str, str)

  def __init__(self):
    super(mybeautifulthread, self).__init__()

  def run(self):
    w = mybeautifulclass()
    w.say_love()
    self.trigger.emit('lo', 've')


def main():
  app = qapplication(sys.argv)
  w = mybeautifulclass()
  w.show()
  sys.exit(app.exec_())


if __name__ == '__main__':
  main()
