python - How to get scalebars continously output inside a while loop tkinter -

-

I programmed a guinea with a typiler and applied a scalebar to change a variable. I am trying to get the output of this scalebar inside the one-time loop.

  • Press the button position = true
  • Get the bar scalab with reading () method
  • Pass the variable in another function
  • Scalabar -> Check 1.
  • The second button press set position = false -> exit while loop

    • My code stuck and I can not change the scalab when I am inside the loop And I had to be forced to leave my code

    I hope you have any idea! The code example is below, if you need more or overall source code then let me know

    best regards,

    intake death 

      class FunctionClassTest: def __init __ (self): pass def intimeSTOP (self): self.Test = wrong def intime (self): self.test = true while self.test: self.TestTmp = scalebarTime.get () if self.TestTmp & Lt; 0: ... playwriter ... online = function classista () button c = button (window, text = "test on", command = online. Intime) button d = button (window, text = "test of", command = Online IntimeSTOP)   
     
     
     The problem is while loop it fights with the tanker loop and Locks the GUI effectively, while continuously executing the loop, making the GUI unresponsive. Here is an example:  
      class app (frame): def __init __ (self, if you have a handful of options, Guardian): frame .__ init __ (self, parent) self.timer = none # timer variable self Slyide = Scale (self) self.slide.pack () button (auto, text = 'go', command = self. _start). Pack () button (self, text = 'stop', command = self._stop). Pack () Def _start (self): If self.slide.get ()> 0: # ... here the code ... i.e., print self.slide.get () # after the set timer method, call it every 1000ms self.timer = self.after (1000, self._start) def _stop ( Self: If there is no self.timer: #cancel timer, automatic .twm (self.timer) root = Tk () app = app (root) app.pack () root.mainloop () _start method with looping For more information on blocking

When the user touches the screen, the fuel once Dairejh these is my code: lifeBar = display.newImage ( "fuel_bar1.png") lifeBar.anchorX = 0 lifeboats. ======================== Lifetime Y = 37 screens Group: The Insert function (called Laifbar) However, I fuel Kansmoshn (equivalent to "pressed" variable to reduce the fuel tank "true") Have used. When pressed == is true, it means that the user is touching the screen: processed (fuel) processed () if life & gt; 0 and pressed == true remains = life - life 1 Life = life =. Wide-1 remains Value.text = string.format ("% d", life) End of this This function is active as the entrance event: runtime: addEventListener ( "Antrfrem" fuel Snsadna) it is very well, but my question is: pressed variable each time 5 seconds (once = = True) How is it possible to reduce the vitality width?
