## Description

GtkIconView provides an alternative view on a list model. 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.

## Details

### GtkIconView

    typedef struct _GtkIconView GtkIconView;

The GtkIconView struct contains only private fields and should not be directly accessed.

### GtkIconViewForeachFunc ()

    void        (*GtkIconViewForeachFunc)       (GtkIconView *icon_view,
                                                 GtkTreePath *path,
                                                 gpointer data);

A function used by `gtk_icon_view_selected_foreach()` to map all selected rows. It will be called on every selected row in the view.

`icon_view` : | a GtkIconView
`path` : | The GtkTreePath of a selected row
`data` : | user data

### gtk_icon_view_new ()

    GtkWidget*  gtk_icon_view_new               (void);

Creates a new GtkIconView widget

Returns : | A newly created GtkIconView widget

Since 2.6

### gtk_icon_view_new_with_model ()

    GtkWidget*  gtk_icon_view_new_with_model    (GtkTreeModel *model);

Creates a new GtkIconView widget with the model `model`.

`model` : | The model.
Returns : | A newly created GtkIconView widget.

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.

This function is often followed by `gtk_widget_grab_focus (icon_view)` in order to give keyboard focus to the widget. Please note that editing can only happen when the widget is realized.

`icon_view` : | A GtkIconView

Moves the alignments of `icon_view` to the position specified by `path`. `row_align` determines where the row is placed, and `col_align` determines where `column` is placed. Both are expected to be between 0.0 and 1.0. 0.0 means left/top alignment, 1.0 means right/bottom alignment, 0.5 means center.

If `use_align` is `FALSE`, then the alignment arguments are ignored, and the tree does the minimum amount of work to scroll the item onto the screen. This means that the item will be scrolled to the edge closest to its current position. If the item is currently visible on the screen, nothing is done.

This function only works if the model is set, and `path` is a valid row on the model. If the model changes before the `icon_view` is realized, the centered path will be modified to reflect this change.

`icon_view` : | A GtkIconView.
`path` : | The path of the item to move to.
`use_align` : | whether to use alignment arguments, or `FALSE`.
`row_align` : | The vertical alignment of the item specified by `path`.

Sets `start_path` and `end_path` to be the first and last visible path. Note that there may be invisible paths in between.

Both paths should be freed with `gtk_tree_path_free()` after use.

`icon_view` : | A GtkIconView
`start_path` : | Return location for start of region, or `NULL`
`end_path` : | Return location for end of region, or `NULL`

### gtk_icon_view_set_reorderable ()

    void        gtk_icon_view_set_reorderable   (GtkIconView *icon_view,
                                                 gboolean 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.

This function does not give you any degree of control over the order -- any reordering is allowed. If more control is needed, you should probably handle drag and drop manually.

`icon_view` : | A GtkIconView.
`reorderable` : | `TRUE`, if the list of items can be reordered.

Since 2.8

### gtk_icon_view_get_reorderable ()

    gboolean    gtk_icon_view_get_reorderable   (GtkIconView *icon_view);

Retrieves whether the user can reorder the list via drag-and-drop. See `gtk_icon_view_set_reorderable()`.

`icon_view` : | a GtkIconView
Returns : | `TRUE` if the list can be reordered.
