对于tkinter的各个控件

对于tkinter的依次控件,能够参见  :

本条早已相比较完美了

今天使用tkinter完成一下百度,抖音的加载- –
又是造轮子,首先看一下跌实的功能图图片 1

导包:

1 from tkinter import *
2 import time

内需小心的是tkinter中的t必须是小写字母

注重控件及自变量:

 1      master = Tk()
 2         master.title('this is a waitpic Demo')
 3         title = Label(master, text='请选择等待图案',font='15',bg='yellow',fg='grey')
 4         title.pack(fill=X)
 5 
 6         self.canvaswidth = 1000
 7         self.canvasheight = 600
 8         self.centerx = self.canvaswidth // 2
 9         self.centery = self.canvasheight // 2
10         self.topx = self.centerx - 50
11         self.topy = self.centery -50
12         self.bottomx = self.centerx + 50
13         self.bottomy = self.centery + 50
14         self.mycanvas = Canvas(master, width=self.canvaswidth,height=self.canvasheight, bg='White')
15         self.mycanvas.pack() 
16         self.mycanvas.create_text(100,20,text='happy life exeryday')
17 
18         bt1 = Button(master,text='图案1',command=self.display1)
19         bt2 = Button(master,text='图案2',command=self.display2)
20         btclear = Button(master,text='清空',command=self.clearCanvas)
21         bt1.pack(side=LEFT)
22         bt2.pack(side=LEFT)
23         btclear.pack(side=RIGHT)

对于tkinter的各个控件。对于tkinter的各个控件。对于tkinter的各个控件。关键增加控件的逻辑是:

对于tkinter的各个控件。1.宣称一个Tk()对象,或然是frame对象

2.对于控件 :   控件x(tk/frame,**对于tkinter的各个控件。kwargs)

3.对控件举办布局,参见一同来给的博客

增添控件后,记得加上,如此技巧有展现

master.mainloop()

对于百度的加载框的得以实现:

1.兑现思路: 四个圆交替,查找API,看到非常实用的move,update—->get~

 1         olred = self.mycanvas.create_oval(self.topx, self.topy, self.bottomx, self.bottomy, tag='display1', fill='red')
 2         olyellow = self.mycanvas.create_oval( self.topx, self.topy, self.bottomx, self.bottomy, tag='display1', fill='yellow')
 3         olgreen = self.mycanvas.create_oval( self.topx, self.topy, self.bottomx , self.bottomy, tag='diaplay1', fill='green')
 4         ols = [olred, olyellow, olgreen]
 5         movingx , movingy = 0, 1
 6         for count in range(4):
 7             for i in range(100):
 8                 self.mycanvas.move(ols[movingx % 3],-2, 0)
 9                 self.mycanvas.move(ols[movingy % 3],+2, 0)
10                 self.mycanvas.update()
11                 time.sleep(0.01)
12             for j in range(100):
13                 self.mycanvas.move(ols[movingx % 3],+2,0)
14                 self.mycanvas.move(ols[movingy % 3],-2,0)
15                 self.mycanvas.update()
16                 time.sleep(0.01)
17             movingx += 1
18             movingy += 1

对于抖音的加载框的兑现:由于抖音刷的太快..小编也没看太掌握啊,就先达成成这样.. 
:有造轮子的大佬可以互相研讨一下

 1 sizes = [size for size in range(0,100,5)]
 2         ols = []
 3         colors = ['red','green']
 4         cx , cy = 0,1
 5         for count in range(10):
 6             for offset in sizes:
 7                 olleft = self.mycanvas.create_oval(self.topx - 100 + offset,self.topy + offset,self.bottomx -100 - offset,self.bottomy - offset,
 8                                                 fill=colors[cx % 2],outline=colors[cx % 2],tag='display2')
 9                 olright = self.mycanvas.create_oval(self.topx + offset,self.topy + offset,self.bottomx-offset,self.bottomy - offset,
10                                                 fill=colors[cy % 2],outline=colors[cy % 2],tag='display2')
11                 ols.append(olleft)
12                 ols.append(olright)
13                 self.mycanvas.move(olleft,offset,0)
14                 self.mycanvas.move(olright,-offset,0)
15                 self.mycanvas.update()
16                 time.sleep(0.1)
17             
18             for ol in ols:
19                 self.mycanvas.delete(ol) 
20             cx += 1
