Python 如何将主GUI中的一个属性转换为代码中的第二个GUI？

单击“构建/升级”按钮时，尝试获取要考虑的self.MetalResource、self.CrystalResource和self.GasResource。但当单击它时，它表示MetalMineGUI ahs现在具有self.MetalResource属性

问题在于

MetalResource

、

CrystalResource

和

GasResource

是

空间

类的属性，而不是

MetalMineGUI

类，并且

MetalMineGUI

没有对

空间

类的引用

您这样定义了类

我不确定你的意图是什么，但我不认为你有任何理由需要这样做。相反，试着做一些类似的事情

class OuterClass():

    def my_method(self):

        class InnerClass():
            pass

如前所述，

升级

功能范围中未定义金属。因此，您需要将成本计算转移到

升级

功能或类似功能中

class Space(Frame):
    ...

class MetalMineGui(Frame):

    def __init__(self, master, space):
        self.space = space
        ...

    def Upgrade(self):
        self.space.MetalResource -= Metal
        ...
