This application provides a front end for several short scripts that \
|
|
demonstrate what you can do with Tk widgets. Each of the numbered \
|
|
lines below describes a demonstration; you can click on it to invoke \
|
|
the demonstration. Once the demonstration window appears, you can \
|
|
click the "See Code" button to see the Ruby/Tk code that created the \
|
|
demonstration. If you wish, you can edit the code and click the \
|
|
"Rerun Demo" button in the code window to reinvoke the demonstration \
|
|
with the modified code. \
|
|
Don't worry about breaking the source code. \
|
|
Your modifications are not reflected on the original file. \
|
|
Please try many kind of changes.
|
|
|
|
Some demo scripts require the recent version of Tk library \
|
|
(e.g. Tk8.4 or later) \
|
|
If your Tk library linked to Ruby doesn't support the functions \
|
|
required by the demo script, the demo doesn't work. \
|
|
In such a case, please re-compile tcltklib with the later Tk library \
|
|
which supports the required functions.
|
|
|
|
If your Tk supports Ttk (Tile) extension (included or installed), \
|
|
please try the demo of Ttk extension (sample/tkextlib/tile/demo.rb) too.
|
|
( Probably, Ttk extension \
|
|
