### Class

# Gtk IconView

deprecated: 4.10

#### Description [src]

    final class Gtk.IconView : Gtk.Widget
      implements Gtk.Accessible, Gtk.Buildable, Gtk.CellLayout, Gtk.ConstraintTarget, Gtk.Scrollable {
      /* No available fields */
    }

`GtkIconView` is a widget which displays data in a grid of icons.

`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

    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.

Deprecated since: 4.10

Use `GtkGridView` instead.

Selects all the icons. `icon_view` must has its selection mode set to `GTK_SELECTION_MULTIPLE`.

deprecated: 4.10

###### gtk_icon_view_select_path

Selects the row at `path`.

deprecated: 4.10

###### gtk_icon_view_selected_foreach

Calls a function for each selected icon. Note that the model or selection cannot be modified from within this function.

deprecated: 4.10

###### gtk_icon_view_set_cursor

Sets the current keyboard focus to be at `path`, and selects it. This is useful when you want to focus the user’s attention on a particular item. If `cell` is not `NULL`, then focus is given to the cell specified by it. Additionally, if `start_editing` is `TRUE`, then editing should be started in the specified cell.

deprecated: 4.10

###### gtk_icon_view_set_drag_dest_item

Sets the item that is highlighted for feedback.

deprecated: 4.10

###### gtk_icon_view_set_item_orientation

Sets the ::item-orientation property which determines whether the labels are drawn beside the icons instead of below.

deprecated: 4.10

###### gtk_icon_view_set_markup_column

Sets the column with markup information for `icon_view` to be `column`. The markup column must be of type `G_TYPE_STRING`. If the markup column is set to something, it overrides the text column set by gtk_icon_view_set_text_column().

deprecated: 4.10

###### gtk_icon_view_set_model

deprecated: 4.10

###### gtk_icon_view_set_pixbuf_column

Sets the column with pixbufs for `icon_view` to be `column`. The pixbuf column must be of type `GDK_TYPE_PIXBUF`.

deprecated: 4.10

###### gtk_icon_view_set_reorderable

This function is a convenience function to allow you to reorder models that support the `GtkTreeDragSourceIface` and the `GtkTreeDragDestIface`. Both `GtkTreeStore` and `GtkListStore` support these. If `reorderable` is `TRUE`, then the user can reorder the model by dragging and dropping rows. The developer can listen to these changes by connecting to the model’s row_inserted and row_deleted signals. The reordering is implemented by setting up the icon view as a drag source and destination. Therefore, drag and drop can not be used in a reorderable view for any other purpose.

Sets the column with text for `icon_view` to be `column`. The text column must be of type `G_TYPE_STRING`.

deprecated: 4.10

###### gtk_icon_view_set_tooltip_cell

Sets the tip area of `tooltip` to the area which `cell` occupies in the item pointed to by `path`. See also gtk_tooltip_set_tip_area().

deprecated: 4.10

###### gtk_icon_view_set_tooltip_column

If you only plan to have simple (text-only) tooltips on full items, you can use this function to have `GtkIconView` handle these automatically for you. `column` should be set to the column in `icon_view`’s model containing the tooltip texts, or -1 to disable this feature.

deprecated: 4.10

###### gtk_icon_view_set_tooltip_item

Sets the tip area of `tooltip` to be the area covered by the item at `path`. See also `gtk_icon_view_set_tooltip_column()` for a simpler alternative. See also gtk_tooltip_set_tip_area().

deprecated: 4.10

###### gtk_icon_view_unselect_all

Unselects all the icons.

deprecated: 4.10

###### gtk_icon_view_unselect_path

Unselects the row at `path`.

deprecated: 4.10

###### gtk_icon_view_unset_model_drag_dest

deprecated: 4.10

###### gtk_icon_view_unset_model_drag_source

Undoes the effect of gtk_icon_view_enable_model_drag_source(). Calling this method sets `GtkIconView`:reorderable to `FALSE`.
