# 選像鈕-核取方塊
###### tags: `活用tkinter – 學習運用GUI`

## 基本的選項鈕
* 點擊型式

from tkinter import *

def sel():
    num = var.get()
    if num == 1:
        label.config(text = "你是男的")
    else:
        label.config(text = "你是女的")

root = Tk()
root.title("python-tkinter")
root.geometry("600x600")
root.config(bg = "lightgreen")

var = IntVar()
var.set(1) 
# 預設男性

label = Label(root, text = "預設", bg = "lightblue", width = 30)
label.pack()

man = Radiobutton(root, text = "男的", variable = var, value = 1, command = sel)
man.pack()

girl = Radiobutton(root, text = "女的", variable = var, value = 2, command = sel)
girl.pack()

root.mainloop()

* 結果

* 也可以修改成 :point_down:

from tkinter import *

def sel():
    label.config(text = "你是 " + var.get())


var = StringVar()
var.set("男生")

label = Label(root, text = "預設", bg = "lightblue", width = 30)
label.pack()

man = Radiobutton(root, text = "男的", variable = var, value = "男生", command = sel)

girl = Radiobutton(root, text = "女的", variable = var, value = "女生", command = sel)

# 此為修改過的部分

* 應用在字典上

from tkinter import *

def sel():
   label.config(text = "你是 " + gems[var.get()])


gems = {0 : "男的", 1 : "女的" }

var = IntVar()
var.set("0")

label = Label(root, text = "預設", bg = "lightblue", width = 30)
label.pack()

for val, gem in gems.items():
    Radiobutton(root, text = gem, variable = var, value = val, command = sel).pack()


root.mainloop()

* 結果應該都是一樣的

## 盒子選項鈕

for val, gem in gems.items():
    Radiobutton(root, indicatoron = 0, width = 30, text = gem, 
            variable = var, value = val, command = sel).pack()

* 結果

## 加上圖片的按鈕
* 圖片 :point_down:
* 女

* 範例

from tkinter import *
from PIL import Image, ImageTk

def sel():
   label.config(text = "你是 " + var.get())

root = Tk()
root.title("python-tkinter")
root.geometry("1000x1000")
root.config(bg = "lightgreen")


boy = Image.open("b.jpg")
boy = ImageTk.PhotoImage(boy)

girl = Image.open("g.jpg")
girl = ImageTk.PhotoImage(girl)


var = StringVar()
var.set("男的")

label = Label(root, text = "預設", bg = "lightblue", width = 100, height = 6)
label.pack()

rb = Radiobutton(root, image = boy, variable = var, value = "男的", command = sel)
rb.place(x = 310, y = 100, width = 400, height = 400)

rg = Radiobutton(root, image = girl, variable = var, value = "女的", command = sel)
rg.place(x = 310, y = 600, width = 400, height = 400)

root.mainloop()

* 結果

## 核取方塊
* 簡單的型式

from tkinter import *

root = Tk()
root.title("python-tkinter")
root.geometry("500x500")
root.config(bg = "lightgreen")

label = Label(root, text = "預設", bg = "lightblue", width = 30)
label.grid(row = 0)

var1 = IntVar()
boy_btn = Checkbutton(root, text = "男", variable = var1)
boy_btn.grid(row = 1, sticky = W)

var2 = IntVar()
girl_btn = Checkbutton(root, text = "女", variable = var2)
girl_btn.grid(row = 2, sticky = W)

root.mainloop()

* 結果
