Description

Gnome::Gtk4::IconView is a widget which displays data in a grid of icons.

Gnome::Gtk4::IconView provides an alternative view on a Gnome::Gtk4::R-TreeModel. It displays the model as a grid of icons with labels. Like Gnome::Gtk4::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, Gnome::Gtk4::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), Gnome::Gtk4::IconView will only display the first level of the tree and ignore the tree’s branches.

CSS nodes

Gnome::Gtk4::IconView has a single CSS node with name iconview and style class .view. For rubberband selection, a subnode with name rubberband is used.

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.

Note: The native version of this routine is deprecated in gtk4-lib() since version 4.10

Returns True if the icon pointed to by $path is currently selected. If $path does not point to a valid location, False is returned.

method path-is-selected ( N-Object $path --> Bool )

• $path; A Gnome::Gtk4::N-TreePath to check selection on.

Return value; True if $path is selected..

scroll-to-path

Note: The native version of this routine is deprecated in gtk4-lib() since version 4.10

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.

method scroll-to-path ( N-Object $path, Bool() $use-align, Num() $row-align, Num() $col-align )

• $path; The path of the item to move to.

• $use-align; whether to use alignment arguments, or False..

If $cell is defined, 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.

method set-cursor ( N-Object $path, N-Object() $cell, Bool() $start-editing )

• $path; A Gnome::Gtk4::N-TreePath

• $cell; One of the cell renderers of $icon-view.

method set-pixbuf-column ( Int() $column )

• $column; A column in the currently used model, or -1 to disable.

set-reorderable

Note: The native version of this routine is deprecated in gtk4-lib() since version 4.10

This function is a convenience function to allow you to reorder models that support the GtkTreeDragSourceIface and the GtkTreeDragDestIface. Both Gnome::Gtk4::TreeStore and Gnome::Gtk4::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.

method set-reorderable ( Bool() $reorderable )

• $reorderable; True, if the list of items can be reordered..

set-row-spacing

method set-spacing ( Int() $spacing )

• $spacing; the spacing.

set-tooltip-cell

Note: The native version of this routine is deprecated in gtk4-lib() since version 4.10

Note: The native version of this routine is deprecated in gtk4-lib() since version 4.10

If you only plan to have simple (text-only) tooltips on full items, you can use this function to have Gnome::Gtk4::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, Gnome::Gtk4::Widget:has-tooltip` will be set to True and $icon-view will connect a Gnome::Gtk4::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.

method set-tooltip-column ( Int() $column )

• $column; an integer, which is a valid column number for $icon-view’s model.

set-tooltip-item

Note: The native version of this routine is deprecated in gtk4-lib() since version 4.10
