Detailed Description
Choose an item from a list.
Gtk::DropDown is a widget that allows the user to choose an item from a list of options. The Gtk::DropDown displays the selected choice.
The options are given to Gtk::DropDown in the form of Gio::ListModel, and how the individual options are represented is determined by a Gtk::ListItemFactory. The default factory displays simple strings.
Gtk::DropDown knows how to obtain strings from the items in a Gtk::StringList; for other models, you have to provide an expression to find the strings via set_expression().
Gtk::DropDown can optionally allow search in the popup, which is useful if the list of options is long. To enable the search entry, use set_enable_search().
- CSS nodes
- Gtk::DropDown has a single CSS node with name dropdown, with the button and popover nodes as children.
- See also
- Gtk::ComboBox
