Tkinter按鈕沒有響應（沒有鼠標懸停效果）

Question

我正在編寫一個遊戲，其中包含從客戶端到服務器以及從服務器到客戶端的信息。一個特定的（非玩）客戶端是監視器，它只顯示遊戲板和玩家。這工作正常，唯一不起作用的是GUI上的退出按鈕。一件小事，但我希望它能工作。 :)另外，我認爲代碼可能存在某些問題，即使它有效。

我嘗試了各種不同的命令（sys.exit，quit ...）並沒有修復它。

沒有錯誤信息，按鈕根本沒有任何反應。沒有鼠標懸停效果，如果我點擊它，沒有任何效果相關的代碼（我刪除矩陣和服務器邏輯，因爲我認爲這是不相關的 - 如果不是我會後）：

class Main(): 
def __init__(self, master): 
    self.frame = Frame(master) 
    self.frame.pack() 
    # Has to be counted up by server class 
    rounds = 0 
    # Has to be communicated by server class. If numberwin == numberrobots, 
    # game is won 
    numberwin = 0 
    numberrobots = 2 

def draw(self): 
    if hasattr(self, 'info'): 
     self.info.destroy() 
    if hasattr(self, 'quit'): 
     self.quit.destroy() 
    print "Main should draw this matrix %s" % self.matrix 

    [...] lots of matrix stuff [...] 

    # Pop-Up if game was won 
    # TODO: Make GUI quittable 
    if self.numberwin == self.numberrobots: 
     self.top = Toplevel() 
     self.msg = Message(self.top, text="This game was won!") 
     self.msg.pack(side=LEFT) 
     self.quittop = Button(
      self.top, text="Yay", command=self.frame.destroy) 
     self.quittop.pack(side=BOTTOM) 

    # TODO: Quit GUI 
    self.quit = Button(self.frame, text="Quit", command=self.frame.destroy) 
    self.quit.pack(side=BOTTOM) 

    # Information on the game 
    self.info = Label(
     self.frame, text="Rounds played: {}, Numbers of robots in win condition: {}".format(self.rounds, self.numberwin)) 
    self.info.pack(side=TOP) 


def canvasCreator(self, numberrows, numbercolumns): 
    # Game board 
    self.canvas = Canvas(
     self.frame, width=numbercolumns * 100 + 10, height=numberrows * 100 + 10) 
    self.canvas.pack() 


class Agent(Protocol, basic.LineReceiver): 
master = Tk() 
main = Main(master) 
# So first matrix is treated differently from later matrixes 
flagFirstMatrix = 1 

def connectionMade(self): 
    msg = dumps({"type": "monitor"}) 
    self.sendLine(msg) 
    print "Sent message:", msg 

def dataReceived(self, data): 
    # Decode the json dump 
    print "Data received: %s" % data 
    data = loads(data) 
    self.main.matrix = np.matrix(data["positions"]) 
    self.main.goals = np.matrix(data["goals"]) 
    self.main.next_move_by_agent = data["next_move"] 
    self.main.rounds = data["rounds"] 
    self.main.numberwin = data["win_states"] 
    if self.flagFirstMatrix == 1: 
     self.main.numberrows, self.main.numbercolumns = self.main.matrix.shape 
     self.main.canvasCreator(
      self.main.numberrows, self.main.numbercolumns) 
     self.main.canvas.pack() 
     self.flagFirstMatrix = 0 
    self.main.canvas.delete(ALL) 
    self.main.draw() 
    self.master.update_idletasks() 
    self.master.update()

首先是類代理無壓痕，第二個爲退出按鈕的「呼叫返回「self.frame.destroy從來沒有定義，所以它不會做任何事情。如果你的意思是tkinter銷燬方法，請嘗試self.frame.destroy（）或嘗試明確定義它。您也可以嘗試調用），要麼fram.pack_forget()或fram.grid_forget()

添加master.mainloop（你的最後一行的代碼
