| 195 | 1 # A FormSplit lets you place its children exactly where you want them |
| 2 # (including silly places!). | |
| 3 # It does no explicit geometry management except moving its children | |
| 4 # when it is moved. | |
| 5 # The interface to place children is as follows. | |
| 6 # Before you add a child, you may specify its (left, top) position | |
| 7 # relative to the FormSplit. If you don't specify a position for | |
| 8 # a child, it goes right below the previous child; the first child | |
| 9 # goes to (0, 0) by default. | |
| 10 # NB: This places data attributes named form_* on its children. | |
| 11 # XXX Yes, I know, there should be options to do all sorts of relative | |
| 12 # placement, but for now this will do. | |
