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.)
