我想在大型机中使用小部件创建两个相邻的框架，但我不知道如何使它们都可单击，而且我确信我的代码可以清理。如有任何帮助，我们将不胜感激！
我一开始只是用小部件制作一个框架，然后从那里开始，但我的主要问题是列表构造函数只能采用一个参数。我希望能够对两个框架使用 self.squares 变量，但我不确定如何做到这一点，因此我为第二个框架设置了另一个方形字典，但我认为这会使事情变得不必要的长。下面是我的代码。 #here 是我遇到最麻烦的地方。
class Board(tk.Frame):
def __init__(self, parent, length, width): # self=Frame, parent=root
tk.Frame.__init__(self, parent)
self.parent = parent
self.length = length
self.width = width
self.config(height=100 * self.length, width=100 * self.width)
self.frame1 = tk.Frame()
self.frame2 = tk.Frame()
self.pack()
self.squares = {}
self.squares2 = {}
self.ranks = string.ascii_lowercase
self.buttons_pressed = 0
self.turns = 0
self.sq1 = None # first square clicked
self.sq2 = None
self.sq1_button = None # button associated with the square clicked
self.sq2_button = None
self.set_squares()
def select_piece(self, button):
if self.buttons_pressed == 0:
self.sq1 = list(self.squares.keys())[list(self.squares.values()).index(button)] #here
self.sq1_button = button
self.buttons_pressed += 1
elif self.buttons_pressed == 1: # stores square and button of second square selected
self.sq2 = list(self.squares.keys())[list(self.squares.values()).index(button)]
self.sq2_button = button
if self.sq2 == self.sq1: # prevents self-destruction and allows the user to choose a new piece
self.buttons_pressed = 0
return
if True:
self.squares[self.sq2].config(image=self.sq1_button["image"])
self.squares[self.sq2].image = self.sq1_button["image"]
self.squares[self.sq1].config(image=self.white_images["blank.png"]) # clears sq1
self.squares[self.sq1].image = self.white_images["blank.png"]
self.buttons_pressed = 0
return
def set_squares(self): # fills frame with buttons representing squares
for x in range(5):
for y in range(5):
b = tk.Button(self.frame1, bg=self.square_color, activebackground="lawn green")
b.grid(row=8 - x, column=y)
b2 = tk.Button(self.frame2, bg=self.square_color, activebackground="lawn green")
b2.grid(row=8 - x, column=y)
pos = self.ranks[x] + str(y + 1)
self.squares.setdefault(pos, b,) # creates list of square positions
self.squares2.setdefault(pos, b2)
self.squares[pos].config(command=lambda key=self.squares[pos]: self.select_piece(key))
self.squares2[pos].config(command=lambda key=self.squares2[pos]: self.select_piece(key))
def set_pieces(self): # places pieces in starting positions
dict_rank1_pieces = {"a1": "dirt.png", "b1": "fire.png", "c1": "metal.png", "d1": "water.png", "e1": "wood.png"}
for key in dict_rank1_pieces: # inserts images into buttons
starting_piece = dict_rank1_pieces[key]
self.squares[key].config(image=self.white_images[starting_piece])
self.squares[key].image = self.white_images[starting_piece]
self.squares2[key].config(image=self.white_images[starting_piece])
self.squares2[key].image = self.white_images[starting_piece]
self.frame1.pack(side='left')
self.frame2.pack(side='right')
for rank in range(2, 6): # fill rest with blank pieces
for file in range(5):
starting_piece = "blank.png"
pos = self.ranks[file] + str(rank)
self.squares[pos].config(image=self.white_images[starting_piece])
self.squares[pos].image = self.white_images[starting_piece]
self.squares2[pos].config(image=self.white_images[starting_piece])
self.squares2[pos].image = self.white_images[starting_piece]
root = tk.Tk()
root.geometry("800x800")
board = Board(root, 5, 5)
board.import_pieces()
board.set_pieces()
board.mainloop()
如果您想对两个框架使用相同的
self.squares(idx, key)idxkey以下是所需的修改：
class Board(tk.Frame):
...
def set_squares(self): # fills frame with buttons representing squares
for x in range(5):
for y in range(5):
pos = self.ranks[x] + str(y + 1)
for i, frame in enumerate((self.frame1, self.frame2)):
b = tk.Button(frame, bg=self.square_color, activebackground="lawn green")
b.grid(row=8 - x, column=y, sticky="nsew")
b.config(command=lambda key=b: self.select_piece(key))
# use tuple as key
self.squares[i,pos] = b
def set_pieces(self): # places pieces in starting positions
dict_rank1_pieces = {"a1": "dirt.png", "b1": "fire.png", "c1": "metal.png", "d1": "water.png", "e1": "wood.png"}
for key in dict_rank1_pieces: # inserts images into buttons
starting_piece = dict_rank1_pieces[key]
# use tuple as key
self.squares[0,key].config(image=self.white_images[starting_piece])
self.squares[1,key].config(image=self.white_images[starting_piece])
# suggest to move below two lines to __init__()
self.frame1.pack(side='left')
self.frame2.pack(side='right')
for rank in range(2, 6): # fill rest with blank pieces
for file in range(5):
starting_piece = "blank.png"
pos = self.ranks[file] + str(rank)
# use tuple as key
self.squares[0,pos].config(image=self.white_images[starting_piece])
self.squares[1,pos].config(image=self.white_images[starting_piece])
...
请注意，当前您已经创建了两个带有按钮的框架作为根窗口的子窗口，而不是
Board更新了
set_pieces()def set_pieces(self): # places pieces in starting positions
dict_rank_pieces = {"a": "dirt.png", "b": "fire.png", "c": "metal.png", "d": "water.png", "e": "wood.png"}
blank_piece = "blank.png"
for rank in range(1, 6): # fill rest with blank pieces
for file in range(5):
starting_piece = dict_rank_pieces[self.ranks[file]]
pos = self.ranks[file] + str(rank)
self.squares[0,pos].config(image=self.white_images[starting_piece if rank == 1 else blank_piece])
self.squares[1,pos].config(image=self.white_images[starting_piece if rank == 5 else blank_piece])
self.frame1.pack(side='left')
self.frame2.pack(side='right')
