21 | * @brief Queue widgets | |
22 | * | |
23 | * This file provides both the queue widget and the recently-played widget. | |
460b9539 | 24 | * |
717ba987 RK |
25 | * A queue layout is structured as follows: |
26 | * | |
27 | * <pre> | |
460b9539 | 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) | |
717ba987 | 37 | * </pre> |
460b9539 | 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.) | |
