First, let us go over the Modules we need for this program. Of course, to make the UI, we need the Tkinter, which comes with Python. We import everything from there with*so we can easily use the constants from there. Normally it would be advised only to get the functions and classes...
对于Tkinter, 可以直接用lambda直接设置一些简单callback: b = Button(master, text=”Delete”,command = lambda listbox=listbox: listbox.delete(ANCHOR)) 在这种情况下,需要设定返回值(listbox=),然后才是lambda的参数(listbox). 这种简写方式等效于:(如下code是在一个class内的代码) ...
a = tkinter.Tk() b = demo(a) a.mainloop() Output: Explanation: In the above code snippet, we created an application having 500 pixels wide by 500 pixels tall. The application has no widgets on it. Then, we calledself.root.after()where self.root is a reference to the Tk() object...
