/**

* SECTION:gtkiconview
|
||
* @title: GtkIconView
|
||
* @short_description: A widget which displays a list of icons in a grid
|
||
*
|
||
* #GtkIconView provides an alternative view on a #GtkTreeModel.
|
||
* It displays the model as a grid of icons with labels. Like
|
||
* #GtkTreeView, it allows to select one or multiple items
|
||
* (depending on the selection mode, see gtk_icon_view_set_selection_mode()).
|
||
* In addition to selection with the arrow keys, #GtkIconView supports
|
||
* rubberband selection, which is controlled by dragging the pointer.
|
||
*
|
||
* Note that if the tree model is backed by an actual tree store (as
|
||
* opposed to a flat list where the mapping to icons is obvious),
|
||
* #GtkIconView will only display the first level of the tree and
|
||
* ignore the tree’s branches.
|
||
*
|
||
* # CSS nodes
|
||
*
|
||
* |[<!-- language="plain" -->
|
||
* iconview.view
|
||
* ╰── [rubberband]
|
||
* ]|
|
||
*
|
||
* GtkIconView has a single CSS node with name iconview and style class .view.
|
||
* For rubberband selection, a subnode with name rubberband is used.

/* General notes about layout
|
||
*
|
||
* The icon view is layouted like this:
|
||
*
|
||
* +----------+ s +----------+
|
||
* | padding | p | padding |
|
||
* | +------+ | a | +------+ |
|
||
* | | cell | | c | | cell | |
|
||
* | +------+ | i | +------+ |
|
||
* | | n | |
|
||
* +----------+ g +----------+
|
||
*
|
||
* In size request and allocation code, there are 3 sizes that are used:
|
||
* * cell size
|
||
* This is the size returned by gtk_cell_area_get_preferred_foo(). In places
|
||
* where code is interacting with the cell area and renderers this is useful.
|
||
* * padded size
|
||
* This is the cell size plus the item padding on each side.
|
||
* * spaced size
|
||
* This is the padded size plus the spacing. This is what’s used for most
|
||
* calculations because it can (ab)use the following formula:
|
||
* iconview_size = 2 * margin + n_items * spaced_size - spacing
|
||
* So when reading this code and fixing my bugs where I confuse these two, be
|
||
* aware of this distinction.
