I was wandering if I could dynamically change my GUI and after a few searches
on Google found the grid_remove() function. What I'm wandering now is if there
is a way to group a lot of widgets up into one, and then use the one
grid_remove function which will remove them all.
Is it possible to do this in a class like this?
class group1:
label1=Label(text="Upon clicking the button").grid(row=0,column=0)
label2=Label(text="The menu will dynamically change").grid(row=1,column=0)
group1.grid_remove()
Well, you are on the right track, it is a good idea to structure a
complex GUI by breaking it up into smaller functional pieces. The right
way to do it is called "megawidget", and it's done by making a Frame
which contains the subwidgets; e.g.
=========================
import Tkinter as Tk
import ttk
# python3:
# import tkinter as Tk
# from tkinter import ttk
class dbllabel(ttk.Frame):
def __init__(self, parent, text1, text2):
ttk.Frame.__init__(self, parent)
# python3:
# super(dbllabel, self).__init__(self, parent)
self.l1=ttk.Label(self, text=text1)
self.l2=ttk.Label(self, text=text2)
self.l1.grid(row=0, column=0)
self.l2.grid(row=1, column=0)
# now use the dbllabel in our program
# like a regular widget
root=Tk.Tk()
mainframe = ttk.Frame(root)
mainframe.pack(expand=True, fill=Tk.BOTH)
# here is no difference between making a button
# and our fresh new megawidget
foo=ttk.Button(mainframe, text="Some other widet")
bar=dbllabel(mainframe, text1="First line", text2="Second line")
foo.grid(row=0, column=0)
bar.grid(row=0, column=1)
root.mainloop()
========================
Note that
1) I only have python2 to test it here now, so there might be an error
on the python3 parts
2) I've used ttk widgets all over where possible. This should give the
most expected look and feel on all platforms
3) More complex megawidgets will of course also group functionality
(i.e. reactions to button clicks etc.) in the same megawidget class
