Tkinter Gui Problems

im working on a github project but its not going so well. this code: from tkinter import * def NewFile(): new = Label(root, text='about \n') def OpenFile(): openf = Labe

Solution 1:

from Tkinter import *



root = Tk()
menu = Menu(root)
root.config(menu=menu)
filemenu = Menu(menu)
my_label = Label(root, text="Select Menu")
my_label.place(x=10,y=10)

defmy_command(query):
    my_label.config(text=query)

menu.add_cascade(label="File", menu=filemenu)
filemenu.add_command(label="New", command=lambda x = "New":my_command(x))
filemenu.add_command(label="Open...", command=lambda x = "Open...":my_command(x))
filemenu.add_separator()
filemenu.add_command(label="Exit", command=root.destroy)

helpmenu = Menu(menu)
menu.add_cascade(label="Help", menu=helpmenu)
helpmenu.add_command(label="About...", command=lambda x = "About...":my_command(x))
body = Label(root, text="")
mainloop()

@Lafexlos is correct. You can use all python types(list,dict,var and more...) on GUI design, most important point how to manage all GUI elements, so all need an accessible status.

Don't destroy any GUI element, change and reuse it.

Don't include any external command to mainloop(like:file,network, etc.)

All GUI application required 3 critical section : INIT >> BUILD >> RUN Otherwise you got a lot painful.

Use GUI elements text as variable, of-course if all element is accesible !

I hope helpful and accept @Lafexlos answer not my ! This code work on Python2.7

Solution 2:

You are not using geometry managers(pack/grid/place) on your widgets so tkinter doesn't show those to you.

Also, instead of creating new labels on every click, you can either create all three in global scope and pack&forget on clicks or just create one Label and change its value depending on your needs.
