## 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.

|  | 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.

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.

## set_reorderable()

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. 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.

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.

Since gtkmm 2.8:

Parameters

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

column should be set to the column in icon_view’s model containing the tooltip texts, or -1 to disable this feature.

When enabled, Gtk::Widget::property_has_tooltip() will be set to `true` and icon_view will connect a Gtk::Widget::signal_query_tooltip() signal handler.
