| 21 | * @brief Queue widgets |
| 22 | * |
| 23 | * This file provides both the queue widget and the recently-played widget. |
| 24 | * |
| 25 | * A queue layout is structured as follows: |
| 26 | * |
| 27 | * <pre> |
| 28 | * vbox |
| 29 | * titlescroll |
| 30 | * titlelayout |
| 31 | * titlecells[col] eventbox (made by wrap_queue_cell) |
| 32 | * titlecells[col]->child label (from columns[]) |
| 33 | * mainscroll |
| 34 | * mainlayout |
| 35 | * cells[row * N + c] eventbox (made by wrap_queue_cell) |
| 36 | * cells[row * N + c]->child label (from column constructors) |
| 37 | * </pre> |
| 38 | * |
| 39 | * titlescroll never has any scrollbars. Instead whenever mainscroll's |
| 40 | * horizontal adjustment is changed, queue_scrolled adjusts titlescroll to |
| 41 | * match, forcing the title and the queue to pan in sync but allowing the queue |
| 42 | * to scroll independently. |
| 43 | * |
| 44 | * Whenever the queue changes everything below mainlayout is thrown away and |
| 45 | * reconstructed from scratch. Name lookups are cached, so this doesn't imply |
| 46 | * lots of disorder protocol traffic. |
| 47 | * |
| 48 | * The last cell on each row is the padding cell, and this extends ridiculously |
| 49 | * far to the right. (Can we do better?) |
| 50 | * |
| 51 | * When drag and drop is active we create extra eventboxes to act as dropzones. |
| 52 | * These only exist while the drag proceeds, as otherwise they steal events |
| 53 | * from more deserving widgets. (It might work to hide them when not in use |
| 54 | * too but this way around the d+d code is a bit more self-contained.) |
