Struct gtk4::ColumnView

#[repr(transparent)]
pub struct ColumnView { /* private fields */ }

ColumnView presents a large dynamic list of items using multiple columns with headers.

ColumnView uses the factories of its columns to generate a cell widget for each column, for each visible item and displays them together as the row for this item.

The show-row-separators and show-column-separators properties offer a simple way to display separators between the rows or columns.

ColumnView allows the user to select items according to the selection characteristics of the model. For models that allow multiple selected items, it is possible to turn on rubberband selection, using enable-rubberband.

The column view supports sorting that can be customized by the user by clicking on column headers. To set this up, the Sorter returned by sorter() must be attached to a sort model for the data that the view is showing, and the columns must have sorters attached to them by calling ColumnViewColumn::set_sorter(). The initial sort order can be set with sort_by_column().

The column view also supports interactive resizing and reordering of columns, via Drag-and-Drop of the column headers. This can be enabled or disabled with the reorderable and resizable properties.

ColumnView uses a single CSS node named columnview. It may carry the .column-separators style class, when show-column-separators property is set. Header widgets appear below a node with name header. The rows are contained in a ListView widget, so there is a listview node with the same structure as for a standalone ListView widget. If show-row-separators is set, it will be passed on to the list view, causing its CSS node to carry the .separators style class. For rubberband selection, a node with name rubberband is used.

The main columnview node may also carry style classes to select the style of list presentation: .rich-list, .navigation-sidebar or .data-table.

Accessibility

ColumnView uses the AccessibleRole::TreeGrid role, header title widgets are using the AccessibleRole::ColumnHeader role. The row widgets are using the AccessibleRole::Row role, and individual cells are using the AccessibleRole::GridCell role

Signals

activate

Emitted when a row has been activated by the user, usually via activating the GtkListBase|list.activate-item action.

This allows for a convenient way to handle activation in a columnview. See ListItem::set_activatable() for details on how to use this signal.

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.

Action

query-tooltip

Emitted when the widgets 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).

Implementations

impl ColumnView

pub fn new(model: Option<impl IsA<SelectionModel>>) -> ColumnView

pub fn columns(&self) -> ListModel

Gets the list of columns in this column view.

This list is constant over the lifetime of @self and can be used to monitor changes to the columns of @self by connecting to the ::items-changed signal.

Returns

The list managing the columns

pub fn enables_rubberband(&self) -> bool

Returns whether rows can be selected by dragging with the mouse.

Returns

true if rubberband selection is enabled

Returns

true if rows are activated on single click

pub fn sorter(&self) -> Option<Sorter>

Returns a special sorter that reflects the users sorting choices in the column view.

To allow users to customizable sorting by clicking on column headers, this sorter needs to be set on the sort model underneath the model that is displayed by the view.

See ColumnViewColumn::set_sorter() for setting up per-column sorting.

Here is an example: ⚠️ The following code is in c ⚠️

gtk_column_view_column_set_sorter (column, sorter);
gtk_column_view_append_column (view, column);
sorter = g_object_ref (gtk_column_view_get_sorter (view)));
model = gtk_sort_list_model_new (store, sorter);
selection = gtk_no_selection_new (model);
gtk_column_view_set_model (view, selection);

Returns

the Sorter of @self

pub fn sort_by_column( &self, column: Option<&ColumnViewColumn>, direction: SortType )

Sets the sorting of the view.

This function should be used to set up the initial sorting. At runtime, users can change the sorting of a column view by clicking on the list headers.

This call only has an effect if the sorter returned by sorter() is set on a sort model, and ColumnViewColumn::set_sorter() has been called on @column to associate a sorter with the column.

If @column is None, the view will be unsorted.
