tkinter动态选取控件名字_Python的GUI的guizero库（基于tkinter）介绍（一）

1 说明

1.1 github

https://github.com/KinKir/guizero#https://github.com/lawsie/guizero  #或者这个

1.2 安装

安装pip install guizero#pip3.8 install guizero  #本机安装

1.3 优点：动态gif图片的显示

1.4 测试：本机python3.8，deepin-linux，微软vscode编辑器

2 最简单的一个窗口

#方法一from guizero import Appapp = App()  #默认大小，标题，位置#app = App(,width=800, height=800)  #指定标题和大小app.display()'''#方法二from guizero import *  #里面有很多控件，一起导出，比如App,Box,Windowapp = App()  #默认大小，标题，位置app.display()'''

3 小部件学习

3.1 Text部件

from guizero import *  #Textapp = App()  #默认大小，标题，位置#welcome_message = Text(app, text="Welcome to my app") #默认位置居中顶格和大小#顶左侧中间：align="left",align="center"，注意没有center#right和top，bottom等等， height=1大小决定是不是往下，也就是与顶格线的距离welcome_message = Text(app, text="Welcome to my app",align="top", height=1)app.display()

3.2 PushButton按钮自定义

from guizero import *app = App()intro = Text(app, text="Have a go with guizero and see what you can create.")def tuichu():    #app窗口销毁，就是退出    app.destroy()#定义ok按钮的功能，可以自定义ok = PushButton(app, text="Ok",command=tuichu)app.display()

3.3 弹出框：

3.3.1 yesno(询问窗)

from guizero import App, Textdef do_this_on_close():    # 自定义文字    if app.yesno("Close", "Do you want to quit?"):        app.destroy()app = App()title = Text(app, "哈哈哈")#When user tries to close the window#当点击右上角的关闭窗口的“×”时，弹出询问窗口。app.when_closed = do_this_on_closeapp.display()

3.3.2 question(输入回答窗)

from guizero import App, PushButton, Textdef button_pressed():    name = app.question("Hello", "What's your name?")    if name is not None:        #显示        hello.value = "Hello " + nameapp = App()button = PushButton(app, command=button_pressed, text="Hello")hello = Text(app)app.display()

3.3.3 alert(警示窗)

from guizero import Appapp = App()#带图标的app.info("Info", "This is a guizero app")app.error("Error", "Try and keep these out your code...")app.warn("Warning", "These are helpful to alert users")app.display()

4 优点：gif的动态图片显示

#from guizero import App, Picture, PushButton, infofrom guizero import *app = App()#方法一#anim = Picture(app, "yytd.gif") #默认大小#可自定义显示gif的图的大小#anim.width = 400#anim.height = 400#方法二button = PushButton(app, command=info, args=["button", "you pushed the image"], image="yytd.gif")#button.width = 400#button.height = 400app.display()

优点，tkinter好像不行，我没发现。

5 倒数计时器：

#from guizero import App, Text, PushButton #我讨厌这样from guizero import *app = App("timer")def count_down():    timer.value = int(timer.value) - 1        '''    #这个判断等于0时，继续重复倒数计时    if timer.value == "0":        # cancel counter        timer.cancel(count_down)        # reset counter        timer.value = 10        # setup repeat，每隔1秒        timer.repeat(1000, count_down)    '''    #这是我改进的，注意如果这里采用app.destroy，那么    #app=App()就应该放在前面    if timer.value == "0":        #自定退出        app.destroy()#app = App("timer") #作者原来放在这里的timer = Text(app, text="10")timer.repeat(1000, count_down)app.display()
