Class Details¶

class Gtk.ListBox(**kwargs)¶

Bases:

Gtk.Container

Abstract:

Structure:

Gtk.ListBoxClass

A Gtk.ListBox is a vertical container that contains Gtk.ListBoxRowchildren. These rows can be 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 Gtk.ListBox is often an alternative to Gtk.TreeView, especially when the list contents has a more complicated layout than what is allowed by a Gtk.CellRenderer, or when the contents is interactive (i.e. has a button in it).

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

Gtk.ListBoxRows can be marked as activatable or selectable. If a row is activatable, Gtk.ListBox ::row-activated will be emitted for it when the user tries to activate it. If it is selectable, the row will be marked as selected when the user tries to select it.

The Gtk.ListBox widget was added in GTK+ 3.10.

Gtk.ListBox as Gtk.Buildable

The Gtk.ListBox implementation of the Gtk.Buildable interface supports setting a child as the placeholder by specifying “placeholder” as the “type” attribute of a <child> element. See Gtk.ListBox.set_placeholder() for info.

CSS nodes

list ╰── row[.activatable]

Gtk.ListBox uses a single CSS node named list. Each Gtk.ListBoxRow uses a single CSS node named row. The row nodes get the .activatable style class added when appropriate.

classmethod new()[source]¶

Returns:

a new Gtk.ListBox

Return type:

Gtk.Widget

Creates a new Gtk.ListBox container.

New in version 3.10.

bind_model(model, create_widget_func, *user_data)[source]¶

Parameters:

model (Gio.ListModel or None) – the Gio.ListModel to be bound to self
create_widget_func (Gtk.ListBoxCreateWidgetFunc or None) – a function that creates widgets for items or None in case you also passed None as model
user_data (object or None) – user data passed to create_widget_func

Binds model to self.

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

The contents of self are cleared and then filled with widgets that represent items from model. self is updated whenever model changes. If model is None, self is left empty.

It is undefined to add or remove widgets directly (for example, withGtk.ListBox.insert() or Gtk.Container.add()) while self is bound to a model.

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

New in version 3.16.

drag_highlight_row(row)[source]¶

Parameters:

row (Gtk.ListBoxRow) – a Gtk.ListBoxRow

This is a helper function for implementing DnD onto a Gtk.ListBox. The passed in row will be highlighted via Gtk.Widget.drag_highlight(), and any previously highlighted row will be unhighlighted.

The row will also be unhighlighted when the widget gets a drag leave event.

New in version 3.10.

drag_unhighlight_row()[source]¶

If a row has previously been highlighted via Gtk.ListBox.drag_highlight_row() it will have the highlight removed.

New in version 3.10.

get_activate_on_single_click()[source]¶

Returns:

True if rows are activated on single click, False otherwise

Return type:

bool

Returns whether rows activate on single clicks.

New in version 3.10.

get_adjustment()[source]¶

Returns:

the adjustment

Return type:

Gtk.Adjustment

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

New in version 3.10.

get_row_at_index(index_)[source]¶

Parameters:

index (int) – the index of the row

Returns:

the child Gtk.Widget or None

Return type:

Gtk.ListBoxRow or None

Gets the n-th child in the list (not counting headers). If _index is negative or larger than the number of items in the list, None is returned.

New in version 3.10.

get_row_at_y(y)[source]¶

Parameters:

y (int) – position

Returns:

the row or Nonein case no row exists for the given y coordinate.

Return type:

Gtk.ListBoxRow or None

Gets the row at the y position.

New in version 3.10.

get_selected_row()[source]¶

Returns:

the selected row

Return type:

Gtk.ListBoxRow

Gets the selected row.

Note that the box may allow multiple selection, in which case you should use Gtk.ListBox.selected_foreach() to find all selected rows.

New in version 3.10.

get_selected_rows()[source]¶

Returns:

A GLib.List containing the Gtk.Widget for each selected child. Free with g_list_free() when done.

Return type:

[Gtk.ListBoxRow]

Creates a list of all selected children.

New in version 3.14.

get_selection_mode()[source]¶

Returns:

a Gtk.SelectionMode

Return type:

Gtk.SelectionMode

Gets the selection mode of the listbox.

New in version 3.10.

insert(child, position)[source]¶

Parameters:

child (Gtk.Widget) – the Gtk.Widget to add
position (int) – the position to insert child in

Insert the child into the self at position. If a sort function is set, the widget will actually be inserted at the calculated position and this function has the same effect of Gtk.Container.add().

If position is -1, or larger than the total number of items in theself, then the child will be appended to the end.

New in version 3.10.

invalidate_filter()[source]¶

Update the filtering for all rows. Call this when result of the filter function on the self is changed due to an external factor. For instance, this would be used if the filter function just looked for a specific search string and the entry with the search string has changed.

New in version 3.10.

Update the separators for all rows. Call this when result of the header function on the self is changed due to an external factor.

New in version 3.10.

invalidate_sort()[source]¶

Update the sorting for all rows. Call this when result of the sort function on the self is changed due to an external factor.

New in version 3.10.

prepend(child)[source]¶

Parameters:

child (Gtk.Widget) – the Gtk.Widget to add

Prepend a widget to the list. If a sort function is set, the widget will actually be inserted at the calculated position and this function has the same effect of Gtk.Container.add().

New in version 3.10.

select_all()[source]¶

Select all children of self, if the selection mode allows it.

New in version 3.14.

select_row(row)[source]¶

Parameters:

row (Gtk.ListBoxRow or None) – The row to select or None

Make row the currently selected row.

New in version 3.10.

selected_foreach(func, *data)[source]¶

Parameters:

func (Gtk.ListBoxForeachFunc) – the function to call for each selected child
data (object or None) – user data to pass to the function

Calls a function for each selected child.

Note that the selection cannot be modified from within this function.

New in version 3.14.

set_activate_on_single_click(single)[source]¶

Parameters:

single (bool) – a boolean

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

New in version 3.10.

set_adjustment(adjustment)[source]¶

Parameters:

adjustment (Gtk.Adjustment or None) – the adjustment, or None

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 self is packed inside a Gtk.ScrolledWindow the adjustment from that will be picked up automatically, so there is no need to manually do that.

New in version 3.10.

set_filter_func(filter_func, *user_data)[source]¶

Parameters:

filter_func (Gtk.ListBoxFilterFunc or None) – callback that lets you filter which rows to show
user_data (object or None) – user data passed to filter_func

By setting a filter function on the self 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 filter_func will be called for each row after the call, and it will continue to be called each time a row changes (via Gtk.ListBoxRow.changed()) or when Gtk.ListBox.invalidate_filter() is called.

Note that using a filter function is incompatible with using a model (see Gtk.ListBox.bind_model()).

New in version 3.10.

Parameters:

update_header (Gtk.ListBoxUpdateHeaderFunc or None) – callback that lets you add row headers
user_data (object or None) – user data passed to update_header

By setting a header function on the self 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 update_header can look at the current header widget using Gtk.ListBoxRow.get_header() and either update the state of the widget as needed, or set a new one usingGtk.ListBoxRow.set_header(). If no header is needed, set the header to None.

Note that you may get many calls update_header to this 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 existing header with an identical one.

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

New in version 3.10.

set_placeholder(placeholder)[source]¶

Parameters:

placeholder (Gtk.Widget or None) – a Gtk.Widget or None

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

New in version 3.10.

set_selection_mode(mode)[source]¶

Parameters:

mode (Gtk.SelectionMode) – The Gtk.SelectionMode

Sets how selection works in the listbox. See Gtk.SelectionMode for details.

New in version 3.10.

set_sort_func(sort_func, *user_data)[source]¶

Parameters:

sort_func (Gtk.ListBoxSortFunc or None) – the sort function
user_data (object or None) – user data passed to sort_func

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

The sort_func will be called for each row after the call, and will continue to be called each time a row changes (via Gtk.ListBoxRow.changed()) and whenGtk.ListBox.invalidate_sort() is called.

Note that using a sort function is incompatible with using a model (see Gtk.ListBox.bind_model()).

New in version 3.10.
