macOS 后台 PyQt 线程执行超时

Question

当我点击最小化按钮在后台执行这个操作时，线程经常会超出限制时间执行，唤醒后台的程序就恢复正常了。请耐心等待，大约一分钟后就会出现。

        self.wt.moveToThread(self._thread)

        layout = QHBoxLayout()

        layout.addWidget(self.button1)

        main_frame = QWidget()

        main_frame.setLayout(layout)

        self.setCentralWidget(main_frame)

    def onButtonClick(self):

        self.button1.setText('Running')

        self._thread.started.connect(self.wt.run)

        self._thread.start()

if __name__ == "__main__":

    app = QApplication(sys.argv)

    form = WinForm()

    form.show()

    sys.exit(app.exec_())
