26 | /* A queue layout is structured as follows: | |
27 | * | |
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 | * | |
38 | * titlescroll never has any scrollbars. Instead whenever mainscroll's | |
39 | * horizontal adjustment is changed, queue_scrolled adjusts titlescroll to | |
40 | * match, forcing the title and the queue to pan in sync but allowing the queue | |
41 | * to scroll independently. | |
42 | * | |
43 | * Whenever the queue changes everything below mainlayout is thrown away and | |
44 | * reconstructed from scratch. Name lookups are cached, so this doesn't imply | |
45 | * lots of disorder protocol traffic. | |
46 | * | |
47 | * The last cell on each row is the padding cell, and this extends ridiculously | |
48 | * far to the right. (Can we do better?) | |
49 | * | |
50 | * When drag and drop is active we create extra eventboxes to act as dropzones. | |
51 | * These only exist while the drag proceeds, as otherwise they steal events | |
52 | * from more deserving widgets. (It might work to hide them when not in use | |
53 | * too but this way around the d+d code is a bit more self-contained.) | |
