| 14 | //| Description: | | |
| 15 | //| The base class for holding piles of playing cards. | | |
| 16 | //| This is the basic building block for card games. A pile | | |
| 17 | //| has a position on the screen and an offset for each | | |
| 18 | //| card placed on it e.g. a pack has no offset, but the | | |
| 19 | //| discard pile may be fanned out across the screen. | | |
| 20 | //| | | |
| 21 | //| The pile knows how to draw itself, though this may be | | |
| 22 | //| overridden if the default layout needs to be changed. | | |
| 23 | //| One or more cards can be removed from the top of a pile, | | |
| 24 | //| and single cards can be added to the top of a pile. | | |
| 25 | //| Functions are provided which redraw the screen when | | |
| 26 | //| cards are added or removed. | | |
| 27 | //| | | |
| 28 | //| Cards know which way up they are and how to draw | | |
| 29 | //| themselves. Piles are lists of cards. Piles know which | | |
| 30 | //| cards they contain and where they are to be drawn. | | |
