python tkinter GUI绘制,以及点击更新显示图片代码
时间:2020-03-14来源:电脑系统城作者:电脑系统城
tkinter 绘制GUI简单明了,制作一些简单的GUI足够,目前遇到的一个问题是不能同时排列显示多幅图片(目前没找到同时显示解决方法),
退而求其次,改成增加一个update按钮,每次点下按钮自动更新图片,注释掉的部分是原来的内核包,替换成自己的程序即可
- import tkinter as tk
- from tkinter import *
- from tkinter import ttk
- from urllib.request import urlopen
- from PIL import Image, ImageTk
- #import make_pic_2 在这里导入自己的py包文件
- num=1
- url = "./PICTURE/Rain.png"def calculate(*args):
- print(addr.get(),":",port.get())
- #make_pic_2.main(int(fft.get()),int(start.get()),int(stop.get()),int(cent.get()))
- #调用自己的内核函数def change(): #更新图片操作
- global num
- num=num+1
- if num%3==0:
- url1="./PICTURE/Rain.png"
- pil_image = Image.open(url1)
- img= ImageTk.PhotoImage(pil_image)
- label_img.configure(image = img)
- if num%3==1:
- url1="./PICTURE/Oscillogram.png"
- pil_image = Image.open(url1)
- img= ImageTk.PhotoImage(pil_image)
- label_img.configure(image = img)
- if num%3==2:
- url1="./PICTURE/Spectrum.png"
- pil_image = Image.open(url1)
- img= ImageTk.PhotoImage(pil_image)
- label_img.configure(image = img)
- root.update_idletasks() #更新图片,必须updateroot = Tk()
- root.title("Draw GUI")mainframe = ttk.Frame(root, padding="5 4 12 12")
- mainframe.grid(column=0, row=0, sticky=(N, W, E, S))
- mainframe.columnconfigure(0, weight=1)
- mainframe.rowconfigure(0, weight=1)
- addr = StringVar()
- port = StringVar()
- fft = StringVar()
- cent = StringVar()
- start= StringVar()
- stop = StringVar()ttk.Label(mainframe, text="Address:").grid(column=1, row=1, sticky=W)
- addr_entry = ttk.Entry(mainframe, width=7, textvariable=addr)
- addr_entry.grid(column=2, row=1, sticky=(W, E))ttk.Label(mainframe,text="Port:").grid(column=3, row=1, sticky=W)
- port_entry = ttk.Entry(mainframe, width=7, textvariable=port)
- port_entry.grid(column=4, row=1, sticky=(W, E))ttk.Label(mainframe,text="FFt:").grid(column=1, row=2, sticky=W)
- fft_entry = ttk.Combobox(mainframe, width=7, textvariable=fft)
- fft_entry['values'] = (2048, 4096, 8192)
- fft_entry.current(1)
- fft_entry.grid(column=2, row=2, sticky=(W, E))ttk.Label(mainframe,text="CenterFR:").grid(column=3, row=2, sticky=W)
- cent_entry = ttk.Entry(mainframe, width=7, textvariable=cent)
- cent_entry.grid(column=4, row=2, sticky=(W, E))ttk.Label(mainframe,text="StartFR:").grid(column=1, row=3, sticky=W)
- start_entry = ttk.Entry(mainframe, width=7, textvariable=start)
- start_entry.grid(column=2, row=3, sticky=(W, E))ttk.Label(mainframe,text="StopFR:").grid(column=3, row=3, sticky=W)
- stop_entry = ttk.Entry(mainframe, width=7, textvariable=stop)
- stop_entry.grid(column=4, row=3, sticky=(W, E))ttk.Button(mainframe, text="Draw!",command=calculate).grid(column=2, row=4, sticky=W)
- ttk.Button(mainframe, text="Update!", command=change).grid(column=4, row=4, sticky=W)
- pil_image = Image.open(url)
- img= ImageTk.PhotoImage(pil_image)
- label_img = ttk.Label(root, image = img ,compound=CENTER)
- label_img.grid(column=0,row=5, sticky=W)
- for child in mainframe.winfo_children(): child.grid_configure(padx=5, pady=5)
- addr_entry.focus()root.bind('<Return>', calculate) #主循环,除了这一行可以一直循环,其他行只执行一次root.mainloop()
