一、Label、Button和Scale控件
from tkinter import* def resize(ev=None): label.config(font='Helvetica %d bold' %scale.get()) root = Tk() root.geometry('250x150') #should use x instead of 250*150 label = Label(root, text='new GUI') scale = Scale(root, from_=10, to=40, orient=HORIZONTAL, command=resize) scale.set(12) button = Button(root, text='quit', command=root.quit) label.pack(fill=Y, expand=1) button.pack() #fill 参数告诉 Packer 让 QUIT #按钮占据剩余的水平空间,而 expand 参数则会引导它填充整个水平可视空间 scale.pack(fill=X, expand=1) mainloop()
