I want to create a GUI program base on tkinter. One of the widgets is Text
. I want to add a horizontal scrollbar in it, but it didn't work.
Where did I make a mistake?
from Tkinter import *
import tkFont
class DpWin(object):
def run(self):
root=Tk()
root.geometry('768x612')
title='dp'
root.title(title)
xscrollbar = Scrollbar(root, orient=HORIZONTAL)
xscrollbar.pack(side=BOTTOM, fill=X)
yscrollbar = Scrollbar(root)
yscrollbar.pack(side=RIGHT, fill=Y)
text = Text(root,xscrollcommand=xscrollbar.set,yscrollcommand=yscrollbar.set)
text.pack()
xscrollbar.config(command=text.xview)
yscrollbar.config(command=text.yview)
text.insert(END,'a'*999)
mainloop()
def start(self):
self.b_start.config(state=DISABLED)
self.b_stop.config(state=ACTIVE)
def stop(self):
self.b_stop.config(state=DISABLED)
self.b_start.config(state=ACTIVE)
if __name__=='__main__':
win=DpWin()
win.run()
I've modified your code according to here . There are 2 main differences.
I made it so the textbox doesn't wrap. If you wrap text, there is nothing for the horizontal scrollbar to scroll to.
I used the grid geometry manager on a frame to keep the scrollbars and text widgets together. The advantage to using .grid
is that you actually get scrollbars which are the correct width/height (something you can't achieve with pack
).
...
from Tkinter import *
import tkFont
class DpWin(object):
def run(self):
root=Tk()
root.geometry('768x612')
title='dp'
root.title(title)
f = Frame(root)
f.pack()
xscrollbar = Scrollbar(f, orient=HORIZONTAL)
xscrollbar.grid(row=1, column=0, sticky=N+S+E+W)
yscrollbar = Scrollbar(f)
yscrollbar.grid(row=0, column=1, sticky=N+S+E+W)
text = Text(f, wrap=NONE,
xscrollcommand=xscrollbar.set,
yscrollcommand=yscrollbar.set)
text.grid(row=0, column=0)
xscrollbar.config(command=text.xview)
yscrollbar.config(command=text.yview)
text.insert(END, 'a'*999)
mainloop()
def start(self):
self.b_start.config(state=DISABLED)
self.b_stop.config(state=ACTIVE)
def stop(self):
self.b_stop.config(state=DISABLED)
self.b_start.config(state=ACTIVE)
if __name__=='__main__':
win=DpWin()
win.run()
There is one comment regarding making both x and y scrollbars work within the pack framework. Here is a minimal example:
import tkinter as tk
from tkinter import X, Y, BOTTOM, RIGHT, LEFT, Y, HORIZONTAL
class TextExample(tk.Frame):
def __init__(self, master=None):
super().__init__()
sy = tk.Scrollbar(self)
sx = tk.Scrollbar(self, orient=HORIZONTAL)
editor = tk.Text(self, height=500, width=300, wrap='none')
sx.pack(side=BOTTOM, fill=X)
sy.pack(side=RIGHT, fill=Y)
editor.pack(side=LEFT, fill=Y)
sy.config(command=editor.yview)
sx.config(command=editor.xview)
self.pack()
def main():
root = tk.Tk()
root.geometry("800x500+0+0")
app = TextExample(master=root)
root.mainloop()
if __name__ == '__main__':
main()
