// Provides an expander for a tree-like list.
//
// It is typically placed as a bottommost child into a `GtkListView`
// to allow users to expand and collapse children in a list with a
// [class@Gtk.TreeListModel]. `GtkTreeExpander` provides the common UI
// elements, gestures and keybindings for this purpose.
//
// On top of this, the "listitem.expand", "listitem.collapse" and
// "listitem.toggle-expand" actions are provided to allow adding custom
// UI for managing expanded state.
//
// It is important to mention that you want to set the
// [property@Gtk.ListItem:focusable] property to FALSE when using this
// widget, as you want the keyboard focus to be in the treexpander, and not
// inside the list to make use of the keybindings.
//
// The `GtkTreeListModel` must be set to not be passthrough. Then it
// will provide [class@Gtk.TreeListRow] items which can be set via
// [method@Gtk.TreeExpander.set_list_row] on the expander.
// The expander will then watch that row item automatically.
// [method@Gtk.TreeExpander.set_child] sets the widget that displays
// the actual row contents.
//
// `GtkTreeExpander` can be modified with properties such as
// [property@Gtk.TreeExpander:indent-for-icon],
// [property@Gtk.TreeExpander:indent-for-depth], and
// [property@Gtk.TreeExpander:hide-expander] to achieve a different appearance.
// This can even be done to influence individual rows, for example by binding
// the [property@Gtk.TreeExpander:hide-expander] property to the item count of
// the model of the treelistrow, to hide the expander for rows without children,
// even if the row is expandable.
//
// ## Shortcuts and Gestures
//
// `GtkTreeExpander` supports the following keyboard shortcuts:
//
//   - <kbd>+</kbd> or <kbd>*</kbd> expands the expander.
//   - <kbd>-</kbd> or <kbd>/</kbd> collapses the expander.
//   - Left and right arrow keys, when combined with <kbd>Shift</kbd> or
//     <kbd>Ctrl</kbd>+<kbd>Shift</kbd>, will expand or collapse, depending on
//     the locale's text direction.
//   - <kbd>Ctrl</kbd>+<kbd>␣</kbd> toggles the expander state.
//
// The row can also expand on drag gestures.
//
// ## Actions
//
// `GtkTreeExpander` defines a set of built-in actions:
//
//   - `listitem.expand` expands the expander if it can be expanded.
//   - `listitem.collapse` collapses the expander.
//   - `listitem.toggle-expand` tries to expand the expander if it was collapsed
//     or collapses it if it was expanded.
//
// ## CSS nodes
//
// ```
// treeexpander
// ├── [indent]*
// ├── [expander]
// ╰── <child>
// ```
//
// `GtkTreeExpander` has zero or one CSS nodes with the name "expander" that
// should display the expander icon. The node will be `:checked` when it
// is expanded. If the node is not expandable, an "indent" node will be
// displayed instead.
//
// For every level of depth, another "indent" node is prepended.
//
// ## Accessibility
//
// Until GTK 4.10, `GtkTreeExpander` used the [enum@Gtk.AccessibleRole.group] role.
//
// Since GTK 4.12, `GtkTreeExpander` uses the [enum@Gtk.AccessibleRole.button] role.
// Toggling it will change the `GTK_ACCESSIBLE_STATE_EXPANDED` state.
