# Gtk::IconView Class Reference
[Widgets, Container Widgets]

Inheritance diagram for Gtk::IconView:

[legend]
List of all members.

## Detailed Description

The IconView provides an alternative view of a list model.

It displays the model as a grid of icons with labels. Like the TreeView, it allows the user to select one or multiple items (depending on the selection mode - see set_selection_mode()). In addition to selection with the arrow keys, the IconView supports rubberband selection, by dragging the pointer.

void Gtk::IconView::scroll_to_path | ( | const TreeModel::Path& | path,
|  | bool | use_align,
|  | gfloat | row_align,
|  | gfloat | col_align |
| ) |  |  |

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.

Since gtkmm 2.8:

Parameters:

  | 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 .
  | col_align | The horizontal alignment of the item specified by path .

void Gtk::IconView::set_column_spacing | ( | int | column_spacing | ) |

Sets the column-spacing property which specifies the space which is inserted between the columns of the icon view.

Since gtkmm 2.6:

Parameters:

  | column_spacing | The column spacing.

void Gtk::IconView::set_columns | ( | int | columns | ) |

This is useful when you want to focus the user's attention on a particular item. If cell is not `0`, 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.

Since gtkmm 2.8:

Parameters:

  | path | A Gtk::TreePath.
  | cell | One of the cell renderers of icon_view , or `0`.

void Gtk::IconView::set_reorderable | ( | bool | reorderable = `true` | ) |

This function is a convenience function to allow you to reorder models that support the Gtk::TreeDragSourceIface and the Gtk::TreeDragDestIface.

Both Gtk::TreeStore and Gtk::ListStore 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.

Parameters:

  | reorderable | `true`, if the list of items can be reordered.
