pyqt4：在线程Qthread中使用定时器Qtimer

GUI main 部分，主app类中的__init__初始化方法中添加

实例化线程

self.s2_thread=Worker2()

初始化一个定时器

        self.log_get=QtCore.QTimer()

将调用方法和信号绑定

QtCore.QObject.connect(self.s2_thread, QtCore.SIGNAL("get_log_start()"), self.qtimer_get_log)
       

定义触发开始的调用方法

 def qtimer_get_log(self):

        self.log_get.singleShot(30000,self.s2_thread.get_mem_error_logfile_content)
        self.log_get.singleShot(90000,self.s2_thread.get_mem_right_logfile_content)
        self.log_get.start()
     

线程Qthread部分

在线程的run中根据需要的地方发起激活定时器的信号

class Worker2(QtCore.QThread):
    def __init__(self, parent=None):

        QtCore.QThread.__init__(self, parent)

　　def get_mem_error_logfile_content(self):
        filename=host_list['app75']['autologfilename']
        with open(filename,'r') as f:
            self.log_30_sec=f.read()
            print '#'*30
 

　　def get_mem_right_logfile_content(self):
        filename=host_list['app75']['autologfilename']
        with open(filename,'r') as f:
            self.log_90_sec=f.read()
            print '*'*30
    def run(self):
        ......
        self.emit(QtCore.SIGNAL("get_log_start()")) #触发定时器信号
        ......
