python - How can I stop a loop with a Toggle Button -

i´ve made gui wx.slider , wx.togglebutton. goal use slider kind of timeline plot , toggle button start/stop button. ideia is: when press toggle button slider value starts increasing , when press toggle button again stops. i'm using following code , can make slider value increase once starts moving can't stop loop until reaches end of slider. there way stop increase when press toggle button again?

def m_togglebtn1ontogglebutton( self, event ):     value = self.m_togglebtn1.getvalue()     if value == true:         self.m_togglebtn1.setlabel("pause")         in xrange(100):             if == 100:                 self.m_slider1.setvalue(100)             else:                 self.m_slider1.setvalue(i)                 time.sleep(0.1)     else:         self.m_togglebtn1.setlabel("start")         slider_value = self.m_slider1.getvalue()         self.m_slider1.setvalue(slider_value)
