26 /* A queue layout is structured as follows:
31 * titlecells[col] eventbox (made by wrap_queue_cell)
32 * titlecells[col]->child label (from columns[])
35 * cells[row * N + c] eventbox (made by wrap_queue_cell)
36 * cells[row * N + c]->child label (from column constructors)
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.
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.
47 * The last cell on each row is the padding cell, and this extends ridiculously
48 * far to the right. (Can we do better?)
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.)
