Labelframes are used to group related widgets together. \
|
|
The label may be either plain text or another widget. \
|
|
If your Tk library linked to Ruby doesn't include a 'labelframe' widget, \
|
|
this demo doesn't work. Please use later version of Tk \
|
|
which supports a 'labelframe' widget.
