Detailed Description

A ListBox is a vertical container that contains ListBoxRow children.

These rows can by dynamically sorted and filtered, and headers can be added dynamically depending on the row content. It also allows keyboard and mouse navigation and selection like a typical list.

Using ListBox is often an alternative to TreeView, especially when the list contents have a more complicated layout than what is allowed by a CellRenderer, or when the contents are interactive (e.g. contain a button).

Although a ListBox must have only ListBoxRow children you can add any kind of widget to it via prepend(), append() and insert(), and a ListBoxRow widget will automatically be inserted between the list and the widget.

Also see FlowBox.

A ListBox looks like this:

Since gtkmm 3.10:

Member Typedef Documentation

template <typename T_item >
using Gtk::ListBox::SlotCreateWidget = sigc::slot<Gtk::Widget*(const Glib::RefPtr<T_item>&)>

For instance: Gtk::Widget* on_create_widget(const Glib::RefPtr<T_item>& item);.

Called for list boxes that are bound to a Gio::ListModel with bind_model() or bind_list_store() for each item that gets added to the model.

Versions of GTK+ prior to 3.18 called show_all() on the rows created by the SlotCreateWidget, but this forced all widgets inside the row to be shown, and is no longer the case. Applications should be updated to show the desired row widgets.

Since gtkmm 3.22:
Template Parameters
T_itemBase class of the items in the Gio::ListModel. All items must be of type T_item or a type derived from T_item. T_item must be Glib::Object or a type derived from Glib::Object.
Parameters
itemThe item from the model for which to create a widget.
Returns
A Gtk::Widget that represents item.
typedef sigc::slot<bool(ListBoxRow*)> Gtk::ListBox::SlotFilter

For instance: bool on_filter(ListBoxRow* row);.

Will be called whenever the row changes or is added and lets you control if the row should be visible or not.

Parameters
rowThe row that may be filtered
Returns
true if the row should be visible, false otherwise
Since gtkmm 3.10:
typedef sigc::slot<void(ListBoxRow*)> Gtk::ListBox::SlotForeach

For instance, void on_foreach(ListBoxRow* row);.

typedef sigc::slot<int(ListBoxRow*, ListBoxRow*)> Gtk::ListBox::SlotSort

For instance: int on_sort(ListBoxRow* row1, ListBoxRow* row2);.

Compare two rows to determine which should be first.

Parameters
row1The first row
row2The second row
Returns
< 0 if row1 should be before row2, 0 if they are equal and > 0 otherwise
Since gtkmm 3.10:

For instance: void on_update_header(ListBoxRow* row, ListBoxRow* before);.

Whenever row changes or which row is before row changes this is called, which lets you update the header on row. You may remove or set a new one via ListBoxRow::set_header() or just change the state of the current header widget.

Parameters
rowThe row to update
beforeThe row before row, or 0 if it is first

void Gtk::ListBox::append ( Widget child)

Append a widget to the list.

If a sort function is set, the widget will actually be inserted at the calculated position.

Parameters
childThe Gtk::Widget to add.
template <typename T_item , typename T_slot >
void Gtk::ListBox::bind_list_store ( const Glib::RefPtr< Gio::ListStore< T_item >> &  store,
T_slot &&  slot_create_widget 
)

Binds a Gio::ListStore<>.

If this ListBox was already bound to a Gio::ListModel, that previous binding is destroyed. (Gio::ListStore is a Gio::ListModel.)

The contents of the ListBox are cleared and then filled with widgets that represent items from store. The ListBox is updated whenever store changes. If store is an empty Glib::RefPtr, the ListBox is left empty.

It is undefined to add or remove widgets directly (for example, with insert()) while the ListBox is bound to a model.

Note that using a model is incompatible with the filtering and sorting functionality in ListBox. When using a model, filtering and sorting should be implemented by the model.

Since gtkmm 3.22:
Template Parameters
T_itemBase class of the items in the Gio::ListStore. All items must be of type T_item or a type derived from T_item. T_item must be Glib::Object or a type derived from Glib::Object.
T_slotSlotCreateWidget<T_item> or a type that can be converted to SlotCreateWidget<T_item>.
Parameters
storeThe Gio::ListStore<> to be bound.
slot_create_widgetA slot that creates widgets for items.
void Gtk::ListBox::bind_model ( const Glib::RefPtr< Gio::ListModel > &  model,
const SlotCreateWidget< Glib::Object >&  slot_create_widget 
)

Binds a Gio::ListModel.

If this ListBox was already bound to a model, that previous binding is destroyed.

The contents of the ListBox are cleared and then filled with widgets that represent items from model. The ListBox is updated whenever model changes. If model is an empty Glib::RefPtr, the ListBox is left empty.

It is undefined to add or remove widgets directly (for example, with insert()) while the ListBox is bound to a model.

Make row the currently selected row.

Parameters
rowThe row to select or nullptr.
void Gtk::ListBox::selected_foreach ( const SlotForeach slot)
void Gtk::ListBox::set_activate_on_single_click ( bool  single = true)

If single is true, rows will be activated when you click on them, otherwise you need to double-click.

Parameters
singleA boolean.
void Gtk::ListBox::set_adjustment ( const Glib::RefPtr< Adjustment >&  adjustment)

Sets the adjustment (if any) that the widget uses to for vertical scrolling.

For instance, this is used to get the page size for PageUp/Down key handling.

In the normal case when the box is packed inside a Gtk::ScrolledWindow the adjustment from that will be picked up automatically, so there is no need to manually do that.

Parameters
adjustmentThe adjustment, or nullptr.
void Gtk::ListBox::set_filter_func ( const SlotFilter slot)

Sets a filter function.

By setting a filter function on the ListBox one can decide dynamically which of the rows to show. For instance, to implement a search function on a list that filters the original list to only show the matching rows.

The slot will be called for each row after the call, and it will continue to be called each time a row changes (via ListBoxRow::changed()) or when invalidate_filter() is called.

Parameters
slotCallback that lets you filter which rows to show
Since gtkmm 3.10:
void Gtk::ListBox::set_header_func ( const SlotUpdateHeader slot)

Sets a header function.

By setting a header function on the ListBox one can dynamically add headers in front of rows, depending on the contents of the row and its position in the list. For instance, one could use it to add headers in front of the first item of a new kind, in a list sorted by the kind.

The slot can look at the current header widget using ListBoxRow::get_header() and either update the state of the widget as needed, or set a new one using ListBoxRow::set_header(). If no header is needed, use ListBoxRow::unset_header().

Note that you may get many calls to this slot for a particular row when e.g. changing things that don't affect the header. In this case it is important for performance to not blindly replace an exisiting header with an identical one.

The slot function will be called for each row after the call, and it will continue to be called each time a row changes (via ListBoxRow::changed()) and when the row before changes (either by ListBoxRow::changed() on the previous row, or when the previous row becomes a different row). It is also called for all rows when invalidate_headers() is called.

Parameters
slotCallback that lets you add row headers
Since gtkmm 3.10:
void Gtk::ListBox::set_placeholder ( Widget placeholder)

Sets the placeholder widget that is shown in the list when it doesn't display any visible children.

Parameters
placeholderA Gtk::Widget or nullptr.
void Gtk::ListBox::set_selection_mode ( SelectionMode  mode)

Sets how selection works in the listbox.

See Gtk::SelectionMode for details.

Parameters
modeThe Gtk::SelectionMode.
void Gtk::ListBox::set_show_separators ( bool  show_separators = true)

Sets whether the list box should show separators between rows.

Parameters
show_separatorstrue to show separators.
void Gtk::ListBox::set_sort_func ( const SlotSort slot)

Sets a sort function.

By setting a sort function on the ListBox one can dynamically reorder the rows of the list, based on the contents of the rows.

The slot will be called for each row after the call, and will continue to be called each time a row changes (via ListBoxRow::changed()) and when invalidate_sort() is called.

Parameters
slotThe sort function.
Since gtkmm 3.10:
Glib::SignalProxy<void(ListBoxRow*)> Gtk::ListBox::signal_row_activated ( )
Slot Prototype:
void on_my_row_activated(ListBoxRow* row)

Flags: Run Last

The signal_row_activated() signal is emitted when a row has been activated by the user.

Parameters
rowThe activated row.
Glib::SignalProxy<void(ListBoxRow*)> Gtk::ListBox::signal_row_selected ( )
Slot Prototype:
void on_my_row_selected(ListBoxRow* row)

Flags: Run Last

The signal_row_selected() signal is emitted when a new row is selected, or (with a nullptr row) when the selection is cleared.

When the box is using Gtk::SelectionMode::MULTIPLE, this signal will not give you the full picture of selection changes, and you should use the Gtk::ListBox::signal_selected_rows_changed() signal instead.

Parameters
rowThe selected row.
Glib::SignalProxy<void()> Gtk::ListBox::signal_selected_rows_changed ( )
Slot Prototype:
void on_my_selected_rows_changed()

Flags: Run First

The signal_selected_rows_changed() signal is emitted when the set of selected rows changes.
