(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()
|
