Python的GUI各有各特点。

由于只是轻微涉及GUI开发,所以就以轻量级的tkinter来学习。

tkinter的使用:

from tkinter import *

root=Tk()
root.title('我的窗口')
root.geometry('500x500')
root.mainloop()

Button所有的可设置参数

activebackground, activeforeground, anchor,
background, bitmap, borderwidth, cursor,
disabledforeground, font, foreground
highlightbackground, highlightcolor,
highlightthickness, image, justify,
padx, pady, relief, repeatdelay,
repeatinterval, takefocus, text,
textvariable, underline, wraplength

WIDGET-SPECIFIC OPTIONS【特有选项】: command, compound, default, height, overrelief, state, width

from tkinter import *

def hello():
 print("hello")
root=Tk()

# RELIEF=["flat", "raised", "sunken", "solid", "ridge", "groove"]

btn1=Button(root,text='click me')
btn1.config(bg='green',fg='white',cursor='hand1',height=10,width=10,command=hello,relief='sunken')
btn1.config(anchor=LEFT)
btn1.pack()

# for col,i in enumerate(RELIEF):
#  btn=Button(root,text=i,relief=i,anchor=S)
#  btn.grid(row=0,column=col)

root.mainloop()
STANDARD OPTIONS【label的标准可选参数】

 activebackground, activeforeground, anchor,
 background, bitmap, borderwidth, cursor,
 disabledforeground, font, foreground,
 highlightbackground, highlightcolor,
 highlightthickness, image, justify,
 padx, pady, relief, takefocus, text,
 textvariable, underline, wraplength
WIDGET-SPECIFIC OPTIONS【特有选项】:

 height, state, width
from tkinter import *

root=Tk()
root.title('我的窗口')
root.geometry('500x500')

label=Label(text='用户名:',bg='green')
label.grid()
root.mainloop()

image

STANDARD OPTIONS【标准可用参数】

 activebackground, activeforeground, anchor,
 background, bitmap, borderwidth, cursor,
 disabledforeground, font, foreground,
 highlightbackground, highlightcolor,
 highlightthickness, image, justify,
 padx, pady, relief, takefocus, text,
 textvariable, underline, wraplength
#这是一段没有显示Frame 代码
from tkinter import *

root=Tk()
root.geometry('500x500')
frame=Frame(root,height = 200,width = 400,bg = 'black')

Label(frame,text='mylabel').pack()

frame.pack()

root.mainloop()
#下面是探究出缩水原因的代码
from tkinter import *

root=Tk()
root.geometry('500x500')
frame=Frame(root,height = 400,width = 400,bg = 'green')


button1=Button(frame,text='hello')
button1.pack(side=LEFT,padx=5,pady=5)#增加了边距之后,发现出了frame的背景颜色
button2=Button(frame,text='hello')
button2.pack(side=LEFT)
frame.pack(side=TOP)


root.mainloop()

image

#下面的是使用.pack_propagate(0)解决了问题的代码
from tkinter import *

root=Tk()
root.geometry('500x500')
frame=Frame(root,height = 400,width = 400,bg = 'green')

# Label(frame,text='mylabel',padx=5,pady=5).pack(side=LEFT)
button1=Button(frame,text='hello')
button1.pack(side=LEFT,padx=5,pady=5)
button2=Button(frame,text='hello')
button2.pack(side=LEFT)
frame.pack_propagate(0)
