Struct gtk::ListBox[][src]

pub struct ListBox(_);
Expand description

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

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

GtkListBoxRows can be marked as activatable or selectable. If a row is activatable, signal::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 GtkListBox widget was added in GTK+ 3.10.

GtkListBox as GtkBuildable

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

CSS nodes

⚠️ The following code is in plain ⚠️

list
╰── row[.activatable]

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