TKINTER COMBOBOX变量问题

Question

我正在尝试使用更具体地说的fustomtkinter来创建一个ComboBox，并在第一个Combobox中具有变量确定另一个ComboBox的选项是什么。我认为语法可能有所不同，因为它是常规的，而不是标准。看看是否有人可以看我的代码。

这是班级的snipit：

# ---------------- HP Pool Option --------------#
        #HP pool values
        #Low
        hp_low_options = ["Random",
                        "5","10","15","20",
                        "25","30","35","40",
                        "45","50","55","60",
                        "65","70","75","80",
                        "85","90","95","100",
                        ]
        #Medium                
        hp_medium_options = ["Random",
                        "105","110","115","120",
                        "125","130","135","140",
                        "145","150","155","160",
                        "165","170","175","180",
                        "185","190","195","200",
                        ]
        #Large
        hp_high_options = ["Random",
                        "205","210","215","220",
                        "225","230","235","240",
                        "245","250","255","260",
                        "265","270","275","280",
                        "285","290","295","300",
                        ]
        #Extreme
        hp_extreme_options = ["Random",
                        "325","350","375","400",
                        "425","450","475","500",
                        "525","550","575","600",
                        "625","650","675","700",
                        "725","750","775","800",
                        ]

        #Create first combobox for pool type
        hp_pool_label = customtkinter.CTkLabel(master=self.frame_left, text="HP Option")
        hp_pool_label.grid(row=5,column=0)
        current_hp_pool = StringVar() #initialize variable
        hp_pool_combobox = customtkinter.CTkComboBox(master=self.frame_left, 
                                                    variable=current_hp_pool, #set variable in combobox
                                                    values=("Random",
                                                            "Low HP Pool", 
                                                            "Medium HP Pool", 
                                                            "High HP Pool", 
                                                            "Extreme HP Pool"))
        hp_pool_combobox.grid(row=5, column=1)

            #This is where the problems start I think 

            hp_pool_combobox.set("Random")  
            hp_pool_combobox.setvar("Test", current_hp_pool)
            current_hp_pool = hp_pool_combobox.current_value

            if current_hp_pool == "Random":
                hp_pool_selected = (hp_low_options,
                                    hp_medium_options,
                                    hp_high_options,
                                    hp_extreme_options)
            elif current_hp_pool == "Low HP Pool":
                hp_pool_selected = hp_low_options
            elif current_hp_pool == "Medium HP Pool":
                hp_pool_selected = hp_medium_options
            elif current_hp_pool == "High HP Pool":
                hp_pool_selected = hp_high_options
            elif current_hp_pool == "Extreme HP Pool":
                hp_pool_selected = hp_extreme_options
            
            hp_value_combobox = customtkinter.CTkComboBox(master=self.frame_left, values=hp_pool_selected)
            hp_value_combobox.grid(row=5, column=2)
            hp_value_combobox.set("Random")

我认为创建某种形式的偶数是答案，因此当选择新选项时，事件触发器并更改第二个ComboBox选项。感谢您的时间和精力！

一种方法是设置命令 ctkcombobox的选项，并根据回调中的第一个Combobox的选定值更新第二个ComboBox。

以下是一个示例：

import customtkinter as ctk

options = {
    'Low': ('5', '10'),
    'Medium': ('15', '20'),
    'High': ('25', '30'),
    'Extreme': ('35', '40')
}

def on_combo1_selected(value):
    values = ('Random',)
    if value == 'Random':
        for v in options.values():
            values += v
    else:
        values += options[value]
    combo2.configure(values=values)
    combo2.set('')

root = ctk.CTk()

var1 = ctk.StringVar()
combo1 = ctk.CTkComboBox(root, variable=var1, values=('Random',)+tuple(options.keys()), command=on_combo1_selected)
combo1.pack()

var2 = ctk.StringVar()
combo2 = ctk.CTkComboBox(root, variable=var2)
combo2.pack()

root.mainloop()

您可以将逻辑应用于代码。
