Python-为什么不同的Tk标签显示为相同的坐标和不同的对象?

Python-Why does different Tk labels appear as same coordinate and as different objects?

我试图在 Python 中创建一些 Label 子类来告诉您它的 x 和 y 坐标。但是,当我查询 any 标签时,它总是 return (1,1),即使 Tk 对象不同。比如我点击了(2,2)(4,5)标签,输出:

Python 3.5.1 (v3.5.1:37a07cee5969, Dec  6 2015, 01:38:48) [MSC v.1900 32 bit (Intel)] on win32

(1, 1)
.53825904

(1, 1)
.53826736

>>>  

虽然对象不同,但X和Y是一样的! (好吧,我可能点击了不同的坐标,但要注意的是标签不在同一个坐标上

错误代码如下:

try:
    from tkinter import * # Py3
except ImportError:
    from Tkinter import * # Py2

class _MyLabel(Label):
    def __init__(self, *args, **kwargs):
        super().__init__(*args, **kwargs)
        self.x = None
        self.y = None
    def grid(self, x, y):
        self.x = x
        self.y = y
        super().grid(row=y, column=x)
    def location(self):
        return (7 - x + 1, 7 - y + 1)

def gen():
    pass

def check(event):
    print(event.widget.location())
    print(event.widget)
    print()

root = Tk()
sqs = [[_MyLabel(root, height=1, width=2, relief=SUNKEN, bg='white') for i in range(8)] for i in range(8)]
seq = []
for x in range(8):
    for y in range(8):
        sqs[y][x].grid(x, y)
        sqs[y][x].bind('<Button-1>', check)


mainloop()

怎么了?

location() 中使用 self.xself.y 而不是 xy。我不会给你解释,因为我猜你只是忽略了它。
