pyqt4：在線程Qthread中使用定時器Qtimer

GUI main 部分，主app類中的__init__初始化方法中添加

 

實例化線程

self.s2_thread=Worker2()

初始化一個定時器

 
        self.log_get=QtCore.QTimer()

將調用方法和信號綁定

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

 

 

定義觸發開始的調用方法

 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()
     

 

 

線程Qthread部分

在線程的run中根據需要的地方發起激活定時器的信號

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()")) #觸發定時器信號 
        ......
