Question

我正在尝试在pygame中创建类似功能的下拉菜单。该程序由“Drop”类组成，其上有文本，并描述了下拉菜单的一般用途。然后是包装类，其中包含下拉菜单中的所有不同标签。 Child类是标签，可以通过发送错误的“add_child”函数添加到包装类中。

import pygame as pg


doc = "c:/users/user/documents/code/py/pg/project/"
vec = pg.math.Vector2


class Drop(Sprite):
    def __init__(self, parent, **kwargs):
        self.parent = parent

        default = {
            "size":[100, 25],
            "pos":vec(0, 0),
            "bg":pg.Color("#ff0000"),
        }

        for key, value in default.items():
            if key not in kwargs:
                kwargs[key] = value

        self.size = kwargs["size"]
        self.pos = vec(kwargs["pos"])
        self.bg = kwargs["bg"]

        super().__init__()

        class Child(Sprite):
            def __init__(self, parent, **kwargs):
                self.parent = parent

                default = {
                    "size":[100, 25],
                    "pos":vec(0, 0),
                    "bg":pg.Color("#00ff00")
                }

                for key, value in default.items():
                    if key not in kwargs and key != "name":
                        kwargs[key] = value

                self.size = kwargs["size"]
                self.pos = vec(kwargs["pos"])
                self.bg = kwargs["bg"]
                self.name = kwargs["name"]

                super().__init__()

            def render(self):
                self.parent.image.blit(self.image, self.rect)


        class Wraper(Sprite):
            def __init__(self, parent, index=1):

                self.index = index
                self.children = [] # childs which are labels with texts on it

                self.parent = {
                    "0":parent.parent,
                    "1":parent.parent.parent
                }[str(self.index)]

                self.y = {
                    "0":parent.pos.y + parent.size[1],
                    "1":parent.parent.pos.y + parent.parent.size[1]
                }[str(self.index)]


                self.size = [100, 100]
                self.bg = pg.Color("#000000")

                self.x = self.parent.pos.x
                self.pos = vec(self.x, self.y)

                super().__init__()
                # this is a custom sprite initialization class i'ts not the problem


            def add_child(self, **kwargs):
                self.children.append(Child(self, kwargs))

                # this is where the interpreter throws the error
                # aperantly the child class takes 2 positional arguments
                # but i gave 3. but as you can see there are clearly only
                # two arguments given, the parent parameter and kwargs

            def render(self):
                if self.children:
                    for child in self.children:
                        child.render()


                if hasattr(self.parent, "image"):
                    self.parent.image.blit(self.image, self.rect)
                else:
                    self.parent.blit(self.image, self.rect)

        self.wraper = Wraper(self, 1)


    def render(self):
        self.wraper.render()
        self.parent.image.blit(self.image, self.rect)

错误：

152，在add_child中 self.children.append（儿童（自我，kwargs）） TypeError： init （）需要2个位置参数，但是给出了3个

Answer 1

您想要Child(self, **kwargs)，而不仅仅是Child(self, kwargs)。当你想要一个关键字时，它试图将它作为参数发送。

python解释器在没有的情况下抛出类型错误
