好的,我们走了。
from tkinter import * #pygame is the module that has collections of functions that is used to create a window import everything from tkinter
Pygame与tkinter无关,你在这里没有导入pygame,你正在导入tkinter。
class window(Frame): #Frame comes from tkinter is what you think as a window
不,不是。 Frame
小部件就是窗口内的一个框架。它本身并没有画出一个窗口。您的示例中的参数Frame
根本不是Frame
小部件,它的值是Tk()
,它是在tkinter中绘制第一个窗口的函数。
def __init__(self, master = None):#The master widget defines the settings upon initialisation
我实际上对你在这里尝试做的事感到茫然。 master
应该等于Frame
,等于screen
等于Tk()
,但如果我是正确的,那么你要覆盖它并告诉它等于None
?
Frame.__init__(self, master) #This is called the frame class that has been built in python
我不认为你在做你认为你在这里做的事情。 This answer比我更好地解释了它。
def __init__window(self): #creation of the init window
如果我正确地阅读你的程序,那么永远不会调用window.__init__window()
,所以这个功能都不会真正发生。
self.pack(fill=BOTH, expand=1)#The pack function will pack this in our frame
您正试图致电.pack()
self
,.pack()
正在Frame
上呼叫self
。通常情况下,我们不会以这种方式为self
分配值(尽管这是有效的),read this以找出应该使用#placing the button
stop = Button(self, master, message= "Stop")
的内容。
Button
这不是放置 Button
窗口小部件,而是将Button
窗口小部件分配给变量。此外,Button(parent, *attributes)
窗口小部件被声明为message
,并且内置了Button(self.master, text="Stop")
属性。这意味着您要调用的是#intialising the button that will start the stopwatch
stop.place(x=0, y=0)
。
app = window(screen) #The app variable is assigned to the window creation which has the tkinter module
这是你放置按钮的地方,但是从不调用包含它的函数,因此它永远不会发生。
window
你在这里做的是调用班级window.__init__()
,在你当前的程序中所做的就是调用from tkinter import *
class App:
def __init__(self, root):
self.root = root
self.root.title("Reagan Kambayi")
self.stop = Button(self.root, text="Stop")
self.stop.place(x=0, y=0)
root = Tk()
App(root)
root.mainloop()
,这本身就什么都没有。
这意味着没有冒犯,但我认为你对tkinter甚至可能是Pythonic OOP缺乏非常基本的了解。
我相信您在计划中尝试做的事情如下:
<div class="row">
<div class="col-md-3"></div>
<div class="col-md-6"></div>
<div class="col-md-3"></div>
</div>
