GUI

終於看得到惹

Python's easiest GUI

Tkinter

import tkinter as tk

window = tk.Tk()

msg = tk.Label(master=window, text="你好！")
msg.pack()

window.mainloop()

簡單的視窗

import tkinter as tk

window = tk.Tk()
window.geometry("500x500")

msg = tk.Label(master=window, text="你好！")
msg.pack()

window.mainloop()

簡單的視窗(指定大小)

import tkinter as tk

window = tk.Tk()
window.geometry("500x500")

msg = tk.Label(master=window, text="你好！")
msg.pack()

window.mainloop()

文字標籤

import tkinter as tk

window = tk.Tk()

def clk():
  print("尼亂按 ><")

btn = tk.Button(master=window, text="按我！", command=clk)
msg.pack()

window.mainloop()

按鈕

import tkinter as tk

window = tk.Tk()

def clk():
  btn["text"] = "不要亂按 ><"


btn = tk.Button(master=window, text="按我！", command=clk)
btn.pack()

window.mainloop()

變更元件文字

frame - side

import tkinter as tk

window = tk.Tk()
window.geometry("300x300")

label0 = tk.Label(text="我在最上面！")
label0.pack(side = tk.TOP)

label3 = tk.Label(text="我在左邊 ( ～'ω')～ ")
label3.pack(side = tk.LEFT)

label4 = tk.Label(text=" ～('ω'～ ) 窩在右邊")
label4.pack(side = tk.RIGHT)

window.mainloop()

frame - grid

import tkinter as tk

window = tk.Tk()
window.geometry("500x500")

frame = tk.Frame()
frame.grid(row=0, column=0)
label = tk.Label(master=frame, text="左上角")
label.pack()

frame = tk.Frame()
frame.grid(row=1, column=1)
label = tk.Label(master=frame, text="右下角")
label.pack()

window.mainloop()

frame - grid 結合迴圈

import tkinter as tk

window = tk.Tk()
window.geometry("500x500")

def clk():
  print("不要亂按><")

for i in range(3):
  for j in range(3):
    frame = tk.Frame()
    frame.grid(row=i, column=j)
    btn = tk.Button(master=frame, text=str(i) + str(j), width=5, command=clk)
    btn.pack()

window.mainloop()

文字有點小 要怎麼辦呢？

from tkinter import *
from tkinter.font import Font
window = Tk()
textLabel = Label(window, 
                  font = Font(size = 80), 
                  text = '我是變大的字串')
textLabel.pack()
mainloop()

使用 tkinter.font

文字有點單調 加點顏色吧

from tkinter import *
from tkinter.font import Font
window = Tk()
textLabel = Label(window,
                  font = Font(size = 80), 
                  bg = 'blue',
                  fg = 'red', 
                  text = '我是變大的字串')
textLabel.pack()
mainloop()

GUI 版面配置

Label.pack() #自動配置
Label.place(x = 100, y = 150) #精確一些的配置
Label.grid(column = 0, row = 0) #好用又不麻煩

GUI 的變數

StringVar() #字串
IntVar() #整數
DoubleVar() #浮點數
BooleanVar() #布林值

變數的值

num = IntVar() #建立變數
num.set(10) #設定變數的值
i = num.get() #取得變數的值
print(i)
num.set(100)
print(num.get())

透過 GUI 和程式對話

from tkinter import *
window = Tk()
inputNum = Entry(window)

def iuput():
    newNum = inputNum.get()
    print(newNum)

inputBtn = Button(window, text = "輸入", command = iuput)
inputNum.pack()
inputBtn.pack()
mainloop()

實作一下

還記得終極密碼嗎？

來加上 GUI 吧
