Struct cursive::views::ListView [−][src]
Displays a list of elements.
Implementations
impl ListView
[src]
pub fn new() -> ListView
[src]
Creates a new, empty ListView
.
pub fn len(&self) -> usize
[src]
Returns the number of children, including delimiters.
pub fn is_empty(&self) -> bool
[src]
Returns true
if this view contains no children.
Returns false
if at least a delimiter or a view is present.
pub fn children(&self) -> &[ListChild]
[src]
Returns a reference to the children
pub fn get_row(&self, id: usize) -> &ListChild
[src]
Returns a reference to the child at the given position.
pub fn row_mut(&mut self, id: usize) -> &mut ListChild
[src]
pub fn add_child<V>(&mut self, label: &str, view: V) where
V: 'static + IntoBoxedView,
[src]
V: 'static + IntoBoxedView,
Adds a view to the end of the list.
pub fn clear(&mut self)
[src]
Removes all children from this view.
pub fn child<V>(self, label: &str, view: V) -> ListView where
V: 'static + IntoBoxedView,
[src]
V: 'static + IntoBoxedView,
Adds a view to the end of the list.
Chainable variant.
pub fn add_delimiter(&mut self)
[src]
Adds a delimiter to the end of the list.
pub fn delimiter(self) -> ListView
[src]
Adds a delimiter to the end of the list.
Chainable variant.
pub fn remove_child(&mut self, index: usize) -> ListChild
[src]
pub fn set_on_select<F>(&mut self, cb: F) where
F: Fn(&mut Cursive, &String) + 'static,
[src]
F: Fn(&mut Cursive, &String) + 'static,
Sets a callback to be used when an item is selected.
pub fn on_select<F>(self, cb: F) -> ListView where
F: Fn(&mut Cursive, &String) + 'static,
[src]
F: Fn(&mut Cursive, &String) + 'static,
Sets a callback to be used when an item is selected.
Chainable variant.
pub fn focus(&self) -> usize
[src]
Returns the index of the currently focused item.
Panics if the list is empty.
