Struct IconView

👎Deprecated: Since 4.10
Expand description

Use GridView instead IconView is a widget which displays data in a grid of icons.

IconView provides an alternative view on a TreeModel. It displays the model as a grid of icons with labels. Like TreeView, it allows to select one or multiple items (depending on the selection mode, see set_selection_mode()). In addition to selection with the arrow keys, IconView 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), IconView will only display the first level of the tree and ignore the tree’s branches.

§CSS nodes

iconview.view
╰── [rubberband]

IconView has a single CSS node with name iconview and style class .view. For rubberband selection, a subnode with name rubberband is used.

§Properties

§activate-on-single-click

The activate-on-single-click property specifies whether the “item-activated” signal will be emitted after a single click.

Readable | Writeable

§cell-area

The CellArea used to layout cell renderers for this view.

If no area is specified when creating the icon view with gtk_icon_view_new_with_area() a CellAreaBox will be used.

§Signals

§activate-cursor-item

A [keybinding signal]SignalAction which gets emitted when the user activates the currently focused item.

Applications should not connect to it, but may emit it with g_signal_emit_by_name() if they need to control activation programmatically.

The default bindings for this signal are Space, Return and Enter.

Action

§item-activated

The ::item-activated signal is emitted when the method gtk_icon_view_item_activated() is called, when the user double clicks an item with the “activate-on-single-click” property set to false, or when the user single clicks an item when the “activate-on-single-click” property set to true. It is also emitted when a non-editable item is selected and one of the keys: Space, Return or Enter is pressed.

§move-cursor

The ::move-cursor signal is a [keybinding signal]SignalAction which gets emitted when the user initiates a cursor movement.

Applications should not connect to it, but may emit it with g_signal_emit_by_name() if they need to control the cursor programmatically.

The default bindings for this signal include

  • Arrow keys which move by individual steps
  • Home/End keys which move to the first/last item
  • PageUp/PageDown which move by “pages” All of these will extend the selection when combined with the Shift modifier.

Action

§select-all

A [keybinding signal]SignalAction which gets emitted when the user selects all items.

Applications should not connect to it, but may emit it with g_signal_emit_by_name() if they need to control selection programmatically.

The default binding for this signal is Ctrl-a.

Action

§select-cursor-item

A [keybinding signal]SignalAction which gets emitted when the user selects the item that is currently focused.

Applications should not connect to it, but may emit it with g_signal_emit_by_name() if they need to control selection programmatically.

There is no default binding for this signal.

Action

§selection-changed

The ::selection-changed signal is emitted when the selection (i.e. the set of selected items) changes.

§toggle-cursor-item

A [keybinding signal]SignalAction which gets emitted when the user toggles whether the currently focused item is selected or not. The exact effect of this depend on the selection mode.

Applications should not connect to it, but may emit it with g_signal_emit_by_name() if they need to control selection programmatically.

There is no default binding for this signal is Ctrl-Space.

Action

§unselect-all

A [keybinding signal]SignalAction which gets emitted when the user unselects all items.

Applications should not connect to it, but may emit it with g_signal_emit_by_name() if they need to control selection programmatically.

The default binding for this signal is Ctrl-Shift-a.

Action

Widget
§destroy

Signals that all holders of a reference to the widget should release the reference that they hold.

May result in finalization of the widget if all references are released.

This signal is not suitable for saving widget state.

§direction-changed

Emitted when the text direction of a widget changes.

§hide

Emitted when @widget is hidden.

§keynav-failed

Emitted if keyboard navigation fails.

See WidgetExt::keynav_failed() for details.

§map

Emitted when @widget is going to be mapped.

A widget is mapped when the widget is visible (which is controlled with visible) and all its parents up to the toplevel widget are also visible.

The ::map signal can be used to determine whether a widget will be drawn, for instance it can resume an animation that was stopped during the emission of unmap.

§mnemonic-activate

Emitted when a widget is activated via a mnemonic.

The default handler for this signal activates @widget if @group_cycling is false, or just makes @widget grab focus if @group_cycling is true.

§move-focus

Emitted when the focus is moved.

The ::move-focus signal is a keybinding signal.

The default bindings for this signal are Tab to move forward, and Shift+Tab to move backward.

Action

§query-tooltip

Emitted when the widget’s tooltip is about to be shown.

This happens when the has-tooltip property is true and the hover timeout has expired with the cursor hovering above @widget; or emitted when @widget got focus in keyboard mode.

Using the given coordinates, the signal handler should determine whether a tooltip should be shown for @widget. If this is the case true should be returned, false otherwise. Note that if @keyboard_mode is true, the values of @x and @y are undefined and should not be used.

The signal handler is free to manipulate @tooltip with the therefore destined function calls.

§realize

Emitted when @widget is associated with a gdk::Surface.

This means that WidgetExt::realize() has been called or the widget has been mapped (that is, it is going to be drawn).

§show

Emitted when @widget is shown.

§state-flags-changed

Emitted when the widget state changes.

See WidgetExt::state_flags().

§unmap

Emitted when @widget is going to be unmapped.

A widget is unmapped when either it or any of its parents up to the toplevel widget have been set as hidden.

As ::unmap indicates that a widget will not be shown any longer, it can be used to, for example, stop an animation on the widget.

§unrealize

Emitted when the gdk::Surface associated with @widget is destroyed.

This means that WidgetExt::unrealize() has been called or the widget has been unmapped (that is, it is going to be hidden).

Source

pub fn scroll_to_path( &self, path: &TreePath, use_align: bool, row_align: f32, col_align: f32, )

👎Deprecated: Since 4.10

Moves the alignments of @self 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 @self is realized, the centered path will be modified to reflect this change.

pub fn set_reorderable(&self, reorderable: bool)

👎Deprecated: Since 4.10

This function is a convenience function to allow you to reorder models that support the GtkTreeDragSourceIface and the GtkTreeDragDestIface. Both TreeStore and 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.

§Deprecated since 4.10

pub fn set_tooltip_column(&self, column: i32)

👎Deprecated: Since 4.10

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

When enabled, GtkWidget:has-tooltip will be set to true and @self will connect a GtkWidget::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.
