53 * SECTION:ctkiconview
54 * @title: CtkIconView
55 * @short_description: A widget which displays a list of icons in a grid
56 *
57 * #CtkIconView provides an alternative view on a #CtkTreeModel.
58 * It displays the model as a grid of icons with labels. Like
59 * #CtkTreeView, it allows to select one or multiple items
60 * (depending on the selection mode, see ctk_icon_view_set_selection_mode()).
61 * In addition to selection with the arrow keys, #CtkIconView supports
62 * rubberband selection, which is controlled by dragging the pointer.
63 *
64 * Note that if the tree model is backed by an actual tree store (as
65 * opposed to a flat list where the mapping to icons is obvious),
66 * #CtkIconView will only display the first level of the tree and
67 * ignore the tree’s branches.
68 *
69 * # CSS nodes
70 *
71 * |[<!-- language="plain" -->
72 * iconview.view
73 * ╰── [rubberband]
74 * ]|
75 *
76 * CtkIconView has a single CSS node with name iconview and style class .view.
77 * For rubberband selection, a subnode with name rubberband is used.

1432 *
1433 * The icon view is layouted like this:
1434 *
1435 * +----------+ s +----------+
1436 * | padding | p | padding |
1437 * | +------+ | a | +------+ |
1438 * | | cell | | c | | cell | |
1439 * | +------+ | i | +------+ |
1440 * | | n | |
1441 * +----------+ g +----------+
1442 *
1443 * In size request and allocation code, there are 3 sizes that are used:
1444 * * cell size
1445 * This is the size returned by ctk_cell_area_get_preferred_foo(). In places
1446 * where code is interacting with the cell area and renderers this is useful.
1447 * * padded size
1448 * This is the cell size plus the item padding on each side.
1449 * * spaced size
1450 * This is the padded size plus the spacing. This is what’s used for most
1451 * calculations because it can (ab)use the following formula:
1452 * iconview_size = 2 * margin + n_items * spaced_size - spacing
1453 * So when reading this code and fixing my bugs where I confuse these two, be
1454 * aware of this distinction.

4164 * Moves the alignments of @icon_view to the position specified by @path.
4165 * @row_align determines where the row is placed, and @col_align determines
4166 * where @column is placed. Both are expected to be between 0.0 and 1.0.
4167 * 0.0 means left/top alignment, 1.0 means right/bottom alignment, 0.5 means
4168 * center.
4169 *
4170 * If @use_align is %FALSE, then the alignment arguments are ignored, and the
