SFrame move scroll

[PraryDogy]

Hi, has tkmacosx.SFrame any option to force move scroll to the bottom or on any coordinates, for example?

Hi

The SFrame widget uses canvas as its main frame and you can access it with sframe['canvas'] through that you can access all features of the canvas one of which is yview_moveto(...). See the Tkinter canvas documentation for all the methods and configurations.

Here is an example of scrolling to the bottom of the frame with the click of a button.

from tkinter import Tk
from tkmacosx import SFrame, Button

root = Tk()
root.geometry('350x400')
sframe = SFrame(root, bg='#E69A8D', scrollbarwidth=3)
sframe.pack(pady=20)

for i in range(50):
    Button(sframe, text='Button %s' % i).pack()

button_to_scoll = Button(root, text="Scroll to bottom",
                         command=lambda: sframe['canvas'].yview_moveto('1.0'))
button_to_scoll.pack()

root.mainloop()

One thing to keep in mind though, is that calling sframe['canvas'].yview_moveto('1.0') before the mainloop won't work unless you update the window with either root.update() or root.update_idletasks() before.
