title: Python Kivy 2 Buttons 2 Different Actions in Same Layout
body: <p>I develop voice assistant with python and ı want to add basic gui with kivyy. 
  I am writing basic gui with kivy and ı want to learn kivy framework so that ı am trying to improve myself with creating GUIs. But in this project ı have an error. Firstly, let me put my code here.</p>
  
  <pre><code>class Assistant(App):
  
  def build(self):
      rl = RelativeLayout()
  
  
  
      b1 = Button(size_hint=(.2, .2),
                  pos_hint={'x': 0, 'top': 1},
                  text="Click For Exit!",
                  color=(1,0, .15, 1))
  
      b2 = Button(size_hint=(.2, .2),
                  pos_hint={'right': 1, 'top': 1},
                  text="Run Program!",
                  color=(8,1, .56, 4))
  
  
      image = Image(source="background_img.jpg")
      b2.bind(on_press=self.RunProgram)
      b1.bind(on_press=self.CloseProgram)
  
  
      textinput = TextInput(font_size=30,
                            size_hint_y=None,
                            height=100,
                            multiline=False,
                            allow_copy=True,
                            auto_indent=True)
  
      textinput.bind(text=self.on_text)
      textinput.bind(on_text_validate=self.on_enter)
  
      rl.add_widget(image)
      rl.add_widget(b1)
      rl.add_widget(textinput)
      rl.add_widget(b2)
  </code></pre>
  
  <p>and for this two button there is their functions.</p>
  
  <pre><code>    def CloseProgram(self, event):
          sys.exit()
  
      def RunProgram(self, event): 
          while True:
                jarvis.run(listen())
  </code></pre>
  
  <p>As you can see ı have 2 button , one is quit from program and the other one is listen users. Also ı have text input that user can input something to give command from keyboard to assistant. But unfortunately when ı click "Run Program" button, Everything is good at first after when ı want to type something or if ı want to click "Exit Program" my GUI stop working. ( everything freezes and crashes ) but in the background my assistant continues to listen to user (me). How can ı solve this problem ? </p>
  
  <p>İn this situation when ı delete while loop everything goes fine but when user wants to talk for assistant  have to click the "Run Program" button every time. Here ı want user can click buttons or can type to text input when program working on background. Thanks in advance. </p>
