class Gtk::IconView

Overview

Gtk::IconView is a widget which displays data in a grid of icons.

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

CSS nodes

iconview.view
╰── [rubberband]

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

def reorderable : Bool #

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


[View source]
def reorderable=(reorderable : Bool) : Nil #

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.

def reorderable? : Bool #

[View source]
def row_spacing : Int32 #

Returns the value of the ::row-spacing property.


[View source]
def row_spacing=(row_spacing : Int32) : Nil #

Sets the ::row-spacing property which specifies the space which is inserted between the rows of the icon view.


[View source]
def scroll_to_path(path : Gtk::TreePath, use_align : Bool, row_align : Float32, col_align : Float32) : Nil #

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.


[View source]
def select_all : Nil #

Selects all the icons. icon_view must has its selection mode set to %GTK_SELECTION_MULTIPLE.


[View source]
def select_all_signal #

[View source]
def select_cursor_item_signal #

[View source]
def select_path(path : Gtk::TreePath) : Nil #

Selects the row at path.


[View source]
def selected_foreach(func : Gtk::IconViewForeachFunc, data : Pointer(Void) | Nil) : Nil #

Calls a function for each selected icon. Note that the model or selection cannot be modified from within this function.


[View source]
def selected_items : GLib::List #

Creates a list of paths of all selected items. Additionally, if you are planning on modifying the model after calling this function, you may want to convert the returned list into a list of Gtk::TreeRowReferences. To do this, you can use gtk_tree_row_reference_new().

To free the return value, use g_list_free_full: |[ Gtk::Widget *icon_view = gtk_icon_view_new (); // Use icon_view

GList *list = gtk_icon_view_get_selected_items (GTK_ICON_VIEW (icon_view));

// use list

g_list_free_full (list, (GDestroyNotify) gtk_tree_path_free); ]|


[View source]
def selection_changed_signal #

[View source]
def selection_mode : Gtk::SelectionMode #

Gets the selection mode of the icon_view.


[View source]
def selection_mode=(mode : Gtk::SelectionMode) : Nil #

Sets the selection mode of the icon_view.


[View source]
def set_cursor(path : Gtk::TreePath, cell : Gtk::CellRenderer | Nil, start_editing : Bool) : Nil #

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 nil, 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.


[View source]
def set_drag_dest_item(path : Gtk::TreePath | Nil, pos : Gtk::IconViewDropPosition) : Nil #

Sets the item that is highlighted for feedback.


[View source]
def set_tooltip_cell(tooltip : Gtk::Tooltip, path : Gtk::TreePath, cell : Gtk::CellRenderer | Nil) : Nil #

Sets the tip area of tooltip to the area which cell occupies in the item pointed to by path. See also gtk_tooltip_set_tip_area().

See also gtk_icon_view_set_tooltip_column() for a simpler alternative.


[View source]
def set_tooltip_item(tooltip : Gtk::Tooltip, path : Gtk::TreePath) : Nil #

Sets the tip area of tooltip to be the area covered by the item at path. See also gtk_icon_view_set_tooltip_column() for a simpler alternative. See also gtk_tooltip_set_tip_area().


[View source]
def spacing : Int32 #

Returns the value of the ::spacing property.


[View source]
def spacing=(spacing : Int32) : Nil #

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


[View source]
def text_column : Int32 #

Returns the column with text for icon_view.


[View source]
def text_column=(column : Int32) : Nil #

Sets the column with text for icon_view to be column. The text column must be of type G_TYPE_STRING.


[View source]
def toggle_cursor_item_signal #

[View source]
def tooltip_column : Int32 #

Returns the column of icon_view’s model which is being used for displaying tooltips on icon_view’s rows.


[View source]
def tooltip_column=(column : Int32) : Nil #

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:has-tooltip will be set to true and icon_view will connect a Gtk::Widget::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.


[View source]
def tooltip_context(x : Int32, y : Int32, keyboard_tip : Bool) : Gtk::TreeIter #

This function is supposed to be used in a Gtk::Widget::query-tooltip signal handler for Gtk::IconView. The x, y and keyboard_tip values which are received in the signal handler, should be passed to this function without modification.

The return value indicates whether there is an icon view item at the given coordinates (true) or not (false) for mouse tooltips. For keyboard tooltips the item returned will be the cursor item. When true, then any of model, path and iter which have been provided will be set to point to that row and the corresponding model.


[View source]
def unselect_all : Nil #

Unselects all the icons.


[View source]
def unselect_all_signal #

[View source]
def unselect_path(path : Gtk::TreePath) : Nil #

Unselects the row at path.


[View source]
def unset_model_drag_dest : Nil #

Undoes the effect of gtk_icon_view_enable_model_drag_dest(). Calling this method sets Gtk::IconView:reorderable to false.


[View source]
def unset_model_drag_source : Nil #

Undoes the effect of gtk_icon_view_enable_model_drag_source(). Calling this method sets Gtk::IconView:reorderable to false.


[View source]
def visible_range : Bool #

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.
