"""Solitaire game, much like the one that comes with MS Windows.
|
||||
|
||||
Limitations:
|
||||
|
||||
- No cute graphical images for the playing cards faces or backs.
|
||||
- No scoring or timer.
|
||||
- No undo.
|
||||
- No option to turn 3 cards at a time.
|
||||
- No keyboard shortcuts.
|
||||
- Less fancy animation when you win.
|
||||
- The determination of which stack you drag to is more relaxed.
|
||||
|
||||
Bugs:
|
||||
|
||||
- When you double-click a card on a temp stack to move it to the suit
|
||||
stack, if the next card is face down, you have to wait until the
|
||||
double-click time-out expires before you can click it to turn it.
|
||||
I think this has to do with Tk's multiple-click detection, which means
|
||||
it's hard to work around.
|
||||
|
||||
Apology:
|
||||
|
||||
I'm not much of a card player, so my terminology in these comments may
|
||||
at times be a little unusual. If you have suggestions, please let me
|
||||
know!
