python 获取⽂本框⾥输⼊的值 _ 如何从 Tkinter ⽂本框⼩⼯具获 取输⼊? 要从python 3中的⽂本框中获取Tkinter输⼊,我使⽤的完整学⽣级程序如下: #Imports all (*) classes, #atributes, and methods of tkinter into the #current workspace from tkinter import * #*********************************** #Creates an instance of the class tkinter.Tk. #This creates what is called the "root" window. By conventon, #the root window in Tkinter is usually called "root", #but you are free to call it by any other name. root = Tk() root.title('how to get text from textbox') #********************************** mystring = StringVar() ####define the function that the signup button will do def getvalue(): ## print(mystring.get()) #************************************* Label(root, text="Text to get").grid(row=0, sticky=W) #label Entry(root, textvariable = mystring).grid(row=0, column=1, sticky=E) #entry textbox WSignUp = Button(root, text="print text", command=getvalue).grid(row=3, column=0, sticky=W) #button ############################################ # executes the mainloop (that is, the event loop) method of the root # object. The mainloop method is what keeps the root window visible. # If you remove the line, the window created will disappear # immediately as the script stops running. This will happen so fast # that you will not even see the window appearing on your screen. # Keeping the mainloop running also lets you keep the # program running until you press the close buton root.mainloop() |
