Python3 uses tkinter to implement a simple ui instance

Use tkinter to create a small window with two buttons, one btn to close the window, and the other btn to switch and execute the two passed functions. simple small code can be used for your reference.

The code is as follows:

Import time
Import tkinter as tk

Class Window:
Def _ init _ (self, title = 'nms', width = 300, height = 120, staFunc = bool, stoFunc = bool ):
Self. w = width
Self. h = height
Self. stat = True
Self. staFunc = staFunc
Self. stoFunc = stoFunc
Self. staIco = None
Self. stoIco = None

Self. root = tk. Tk (className = title)

Def center (self ):
Ws = self. root. winfo_screenwidth ()
Hs = self. root. winfo_screenheight ()
X = int (ws/2)-(self. w/2 ))
Y = int (hs/2)-(self. h/2 ))
Self. root. geometry ('{}x {}+ {}'. format (self. w, self. h, x, y ))

Def packBtn (self ):
Self. btnSer = tk. Button (self. root, command = self. event, width = 15, height = 3)
Self. btnSer. pack (padx = 20, side = 'left ')
BtnQuit = tk. Button (self. root, text = 'close windows', command = self. root. quit, width = 15, height = 3)
BtnQuit. pack (padx = 20, side = 'right ')

Def event (self ):
Self. btnSer ['state'] = 'disabled'
If self. stat:
If self. stoFunc ():
Self. btnSer ['text'] = 'start service'
Self. stat = False
Self. root. iconbitmap (self. stoIco)
Else:
If self. staFunc ():
Self. btnSer ['text'] = 'stop service'
Self. stat = True
Self. root. iconbitmap (self. staIco)
Self. btnSer ['state'] = 'active'

Def loop (self ):
Self. root. resizable (False, False) # Disable window size modification
Self. packBtn ()
Self. center () # center window
Self. event ()
Self. root. mainloop ()
