Tkinter button doesn't respond (has no mouse over effect) - python-2.7

Question

I'm writing a game that has info that is communicated from client to server and from server to client. One specific (non-playing) client is the monitor, which only displays the game board and players. This works fine, the only thing that doesn't work is the quit button on the GUI. A minor thing, but I would like it to work. :) Plus I think that there might be something pretty wrong with the code, even though it works.
I tried all kind of different commands (sys.exit, quit...) and nothing fixed it.
There's no error message, nothing happens with the button at all. No mouse over effect, nothing if I click it. Relevant code (I removed matrix and server logic because I think it's irrelevant - if it isn't I'll post it):
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()

Answer 1

First there is no indentation for class Agent, second for the quit button's "call back" self.frame.destroy is never defined so it doesn't do anything. If you meant tkinter destroy method try self.frame.destroy() or try explicitly defining it. You can also try calling either fram.pack_forget() or fram.grid_forget()
Add master.mainloop() to your last line in terms of the entire lines of code
