如何在python 3.4中使用tkinter添加2个滚动条？

Question

I have the following code:

from win32com.client import Dispatch
from tkinter import *
from tkinter import ttk
import tkinter

class applicazione:

def __init__(self, root):
    self.root = root
    self.root.title('Controllo dati per fatturazione elettronica - Manticle - Smith & Nephew Italia')
    ttk.Frame(self.root, width=300, height=250).pack()

I read data from an excel file (lettura function) but i would like to add an horizontal and a vertical scrollbar i read first of all this:

Adding a scrollbar to a group of widgets in Tkinter

but use "grid" that i do not use and i'm not able to associate my double "for" "Text" to the vertical scroll bar (Lettura function)

and this: How to add a scrollbar to a window with tkinter? that is not organise like a class.

how can i implement the 2 scrollbars?

Answer 1

I've also struggled with creating a double scrollbar window. Here is an implementation using pack layout manager (you should be able to tailor it for a grid layout) :

import tkinter as tk
from tkinter import ttk

# Top-level frame
root = tk.Tk()
root.title( "Double scrollbar with tkinter" )
root.minsize(width = 600, height = 600)
frame = ttk.Frame(root, relief="sunken")

# Canvas creation with double scrollbar
hscrollbar = ttk.Scrollbar(frame, orient = tk.HORIZONTAL)
vscrollbar = ttk.Scrollbar(frame, orient = tk.VERTICAL)
sizegrip = ttk.Sizegrip(frame)
canvas = tk.Canvas(frame, bd=0, highlightthickness=0, yscrollcommand = vscrollbar.set, xscrollcommand = hscrollbar.set)
vscrollbar.config(command = canvas.yview)
hscrollbar.config(command = canvas.xview)


# Add controls here
subframe = ttk.Frame(canvas)

#Packing everything
subframe.pack(padx   = 15, pady   = 15, fill = tk.BOTH, expand = tk.TRUE)
hscrollbar.pack( fill=tk.X, side=tk.BOTTOM, expand=tk.FALSE)
vscrollbar.pack( fill=tk.Y, side=tk.RIGHT, expand=tk.FALSE)
sizegrip.pack(in_ = hscrollbar, side = tk.BOTTOM, anchor = "se")
canvas.pack(side = tk.LEFT, padx  = 5, pady   = 5, fill = tk.BOTH, expand= tk.TRUE)
frame.pack( padx   = 5, pady   = 5, expand = True, fill = tk.BOTH)


canvas.create_window(0,0, window = subframe)
root.update_idletasks() # update geometry
canvas.config(scrollregion = canvas.bbox("all"))
canvas.xview_moveto(0) 
canvas.yview_moveto(0)


# launch the GUI
root.mainloop()

(Tested with Python 3.4).

Exemples :

It's not perfect, since it lacks the small block on the bottom right corner.

UPDATE 1 : Added Sizegrip to get the bottom right resizing corner

UPDATE 2 : Added working solution to OP's updated code

from win32com.client import Dispatch
from tkinter import *
from tkinter import ttk
import tkinter


class applicazione(object):


    def __init__(self, root):
        self.root = root

        # Top-level frame
        self.root.title('Controllo dati per fatturazione elettronica - Manticle - Smith & Nephew Italia')

        self.frame = ttk.Frame(self.root, width=300, height=250)

        # Canvas creation with double scrollbar
        hscrollbar = ttk.Scrollbar(self.frame, orient = tkinter.HORIZONTAL)
        vscrollbar = ttk.Scrollbar(self.frame, orient = tkinter.VERTICAL)
        sizegrip = ttk.Sizegrip(self.frame)
        self.canvas = tkinter.Canvas(self.frame, bd=0, highlightthickness=0, yscrollcommand = vscrollbar.set, xscrollcommand = hscrollbar.set)
        vscrollbar.config(command = self.canvas.yview)
        hscrollbar.config(command = self.canvas.xview)


        # Add controls here
        self.subframe = ttk.Frame(self.canvas)

Just to expand on the answer by @georgesl and demonstrate the use of the ttk sizegrip and also to show that grid works nicely for this kind of task, here is a short example showing a text widget with 2 scrollbars and the sizegrip in the corner.

# Demonstrate text widget with two scrollbars and the sizegrip.
import tkinter as tk
import tkinter.ttk as ttk

root = tk.Tk()
text = tk.Text(root)
vs = ttk.Scrollbar(root, orient="vertical")
hs = ttk.Scrollbar(root, orient="horizontal")
sizegrip = ttk.Sizegrip(root)

# hook up the scrollbars to the text widget
text.configure(yscrollcommand=vs.set, xscrollcommand=hs.set, wrap="none")
vs.configure(command=text.yview)
hs.configure(command=text.xview)

# grid everything on-screen
text.grid(row=0,column=0,sticky="news")
vs.grid(row=0,column=1,sticky="ns")
hs.grid(row=1,column=0,sticky="news")
sizegrip.grid(row=1,column=1,sticky="news")
root.grid_rowconfigure(0, weight=1)
root.grid_columnconfigure(0, weight=1)

def fill():
    for n in range(30):
        text.insert("end", 'hello ' * 20, "", "\n")
root.after(20, fill)
root.mainloop()

Answer 3

The process to add both a horizontal and vertical scrollbar to a collection of widgets is precisely the same as the solution provided in this answer: https://stackoverflow.com/a/3092341/7432 . That answer shows only a vertical scrollbar, but adding a horizontal one is just a matter of a couple lines of code.

The solution is very straight-forward:

• add widgets to a frame using whatever method you want
• add the frame to a canvas using the create_window method of the canvas
• add scrollbars to the canvas in the usual way
• set the scrollregion attribute of the canvas to be big enough to incude the entire frame that was added
  • do this whenever you add or remove widgets from the frame
  • you might also need to do this whenever the canvas changes size
