## 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.

## Member Typedef Documentation

using Gtk::IconView::SlotForeach = sigc::slot<void(const TreeModel::Path&)>

For instance, void on_foreach(const Gtk::TreeModel::Path& path);.

## Member Function Documentation

Cairo::RefPtr<Cairo::Surface> Gtk::IconView::create_drag_icon | ( | const TreeModel::Path& | path | ) |

Creates a #cairo_surface_t representation of the item at path.

This image is used for a drag icon.

Since gtkmm 2.8:

Parameters

  path | A Gtk::TreePath in icon_view.

Returns
  A newly-allocated surface of the drag icon.

void Gtk::IconView::enable_model_drag_dest | ( | const std::vector< TargetEntry >& | targets,
|  | Gdk::DragAction | actions = `Gdk::DragAction::COPY|Gdk::DragAction::MOVE`
| ) |  |

Turns the IconView into a drop destination for automatic DND.

Parameters

  targets | The table of targets that the drag will support.
  actions | The bitmask of possible actions for a drag from this widget.

void Gtk::IconView::enable_model_drag_source | ( | const std::vector< TargetEntry >& | targets,
|  | Gdk::ModifierType | start_button_mask = `Gdk::ModifierType::MODIFIER_MASK`,
|  | Gdk::DragAction | actions = `Gdk::DragAction::COPY|Gdk::DragAction::MOVE`
| ) |  |

Turns the IconView into a drag source for automatic DND.

Parameters

  targets | Standard container of targets that the drag will support.
  start_button_mask | Mask of allowed buttons to start drag.
  actions | The bitmask of possible actions for a drag from this widget.

bool Gtk::IconView::get_activate_on_single_click | ( |  | ) | const

Gets the setting set by set_activate_on_single_click().

|  | 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.

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

Sets the property_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_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.

void Gtk::IconView::set_row_spacing | ( | int | row_spacing | ) |

Sets the property_row_spacing() property which specifies the space which is inserted between the rows of the icon view.

Since gtkmm 2.6:

Parameters

  row_spacing | The row spacing.

void Gtk::IconView::set_selection_mode | ( | SelectionMode | mode | ) |

Sets the selection mode of the icon_view.

Since gtkmm 2.6:

Parameters

  mode | The selection mode.

void Gtk::IconView::set_spacing | ( | int | spacing | ) |

Sets the property_spacing() property which specifies the space which is inserted between the cells (i.e. the icon and the text) of an item.

Since gtkmm 2.6:

Parameters

  spacing | The spacing.

void Gtk::IconView::set_text_column | ( | int | column | ) |

Sets the column with text for icon_view to be column.

The text column must be of type G_TYPE_STRING.

Since gtkmm 2.6:

Parameters

  column | A column in the currently used model, or -1 to display no text.

void Gtk::IconView::set_text_column | ( | const TreeModelColumnBase& | model_column | ) |

Sets the column with text for icon_view to be model_column.

The text column must be of type G_TYPE_STRING.

Since gtkmm 2.6:

Parameters

  model_column | A column in the currently used model, or -1 to display no text.

void Gtk::IconView::set_tooltip_cell | ( | const Glib::RefPtr< Tooltip >& | tooltip,

|  | CellRenderer& | cell
| ) |  |

Sets the tip area of tooltip to the area which cell occupies in the item pointed to by path.

See also Tooltip::set_tip_area().

Since gtkmm 2.12:

Parameters

  tooltip | A Gtk::Tooltip.
  path | A Gtk::TreePath.
  cell | A Gtk::CellRenderer.

void Gtk::IconView::set_tooltip_cell | ( | const Glib::RefPtr< Tooltip >& | tooltip,
|  | const TreeModel::Path& | path
| ) |  |

See also Tooltip::set_tip_area().

Since gtkmm 2.12:

Parameters

  tooltip | A Gtk::Tooltip.
  path | A Gtk::TreePath.

void Gtk::IconView::set_tooltip_column | ( | int | column | ) |

If you only plan to have simple (text-only) tooltips on full items, you can use this function to have Gtk::IconView 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.

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.

Note that the signal handler sets the text with Gtk::Tooltip::set_markup(), so&, <, etc have to be escaped in the text.

Since gtkmm 2.12:

Parameters

  column | An integer, which is a valid column number for icon_view’s model.

void Gtk::IconView::set_tooltip_item | ( | const Glib::RefPtr< Tooltip >& | tooltip,
