python - Get a TK() object from another method -


target

I want to create a popup window with a button, which is when the mouse leaves the window Stops. (This is a submenu of a program.)

To do this, I have a function that is called to open a popup window. It has the following code: 
  master = tc () fpy.ui.menu.submenu (master = master, [... more parameters ...]) mainloop ()

And one way to make everything (fpy.ui.menu.submenu (...)). This function should be as clean as possible. This is part of an API which I am making for my future projects. Def submenu (master, [... more parameters ...]): master.overrideredirect (true) a_frame = frame (master, bg = "gray") # [generate button To codeblock] a_frame.bind ("go left", delete) a_frame.pack () 

  a_frame dam ("leave & lt; The function function is called, when the mouse leaves the frame and now my problem begins, 'deleted' function is called my root (in this case the master is called ) Should be destroyed.  
 Problem:  
  DRF (): # How can I get master-object? Master.destroy ()  
 
 This will make an error! 
 
 information: 
 
     
  •  The function starts' destroying '
    •  
  •  I did' manage to transmitter as the main object parameter 
    •  
  •  Please ignore dots at the beginning of a line Stack exchange editor does not accept indent code. 
    •  
     
     
     option 1: pass it an argument 
     
     You can make a  lambda  statement by using your  delete ()  function: 
     
      a_frame.  
     
     Then modify the signature of your deleted function: 
     
      DRF (master)): Master.destroy ()  
     
     Option 2: Call the demolition method directly on the master 
     
     same  lambda  statement as before, we call it method instead of dealing with it directly to any other function We do. 
     
      a_frame.bind ("leave <">, lambda: master.destroy ())  
     
     Of course, this is not an option If you want to do other stuff in your  delete ()  function.
