(Only supports vertical scrolling)
Sames as tkinter Frame. These are some extra resources.
- `scrollbarwidth`: Set the width of scrollbar.
- `mousewheel`: Set mousewheel scrolling.
- `avoidmousewheel`: Give widgets that also have mousewheel scrolling and is a child of SFrame \
this will configure widgets to support their mousewheel scrolling as well. \
For eg:- Text widget inside SFrame can have mousewheel scrolling as well as SFrame.
Scrollbar of SFrame can be configured by calling `scrollbar_configure(**options)`.
To access methods of the scrollbar it can be called through the scrollbar instance `self['scrollbar']`.
### How to use?
Use it like a normal frame.
### Example:
root = Tk()
frame = SFrame(root, bg='pink')
frame.pack()
for i in range(100):
Button(frame, text='Button %s'%i).pack()
root.mainloop()

- `fps`: Set fps(frames per seconds).
