[−][src]Struct cursive::views::LinearLayout
Arranges its children linearly according to its orientation.
Methods
impl LinearLayout
[src]
pub fn new(orientation: Orientation) -> Self
[src]
Creates a new layout with the given orientation.
pub fn set_weight(&mut self, i: usize, weight: usize)
[src]
pub fn weight(self, weight: usize) -> Self
[src]
Modifies the weight of the last child added.
It is an error to call this before adding a child (and it will panic).
pub fn child<V: View + 'static>(self, view: V) -> Self
[src]
Adds a child to the layout.
Chainable variant.
pub fn add_child<V: View + 'static>(&mut self, view: V)
[src]
Adds a child to the layout.
pub fn insert_child<V: View + 'static>(&mut self, i: usize, view: V)
[src]
pub fn swap_children(&mut self, i: usize, j: usize)
[src]
Swaps two children.
pub fn len(&self) -> usize
[src]
Returns the number of children.
pub fn is_empty(&self) -> bool
[src]
Returns true
if this view has no children.
pub fn get_focus_index(&self) -> usize
[src]
Returns index of focused inner view
pub fn vertical() -> Self
[src]
Creates a new vertical layout.
pub fn horizontal() -> Self
[src]
Creates a new horizontal layout.
pub fn get_child(&self, i: usize) -> Option<&dyn View>
[src]
Returns a reference to a child.
pub fn get_child_mut(&mut self, i: usize) -> Option<&mut dyn View>
[src]
Returns a mutable reference to a child.
pub fn remove_child(&mut self, i: usize) -> Option<Box<dyn View>>
[src]
Removes a child.
If i
is within bounds, the removed child will be returned.
