PyQt编程工作子线程与GUI线程示例

基于PySide6下的Gui编程示例

工作子线程，接收信号后开始工作，run()写程序后台运行逻辑
GUI程序，死循环连接控件信号槽函数

import sys
import time
from PySide6.QtWidgets import QMainWindow, QApplication
from PySide6.QtCore import QThread, Signal
from common.gui import Ui_Form


class WorkThread(QThread):
    trigger = Signal(str)
    # work子线程
    def __init__(self, parent=None) -> None:
        super().__init__(parent)

    def run(self):
        for i in range(1,16):
            time.sleep(1)
            self.trigger.emit(str(i))


class MianWin(QMainWindow, Ui_Form):
    # 主gui程序，死循环
    def __init__(self, parent=None) -> None:
        super().__init__(parent)
        self.setupUi(self)
        self.thread = WorkThread(self)
        self.runButton.clicked.connect(self.start_run)
   
    def display(self, i):
        self.listWidget.addItem(str(i))
       
    def start_run(self):
        self.thread.start()
        self.thread.trigger.connect(self.display)


if __name__ == "__main__":
    app = QApplication(sys.argv)
    window = MianWin()
    window.show()
    sys.exit(app.exec())
