[−][src]Struct cursive::views::LinearLayout
Arranges its children linearly according to its orientation.
Examples
use cursive_core::views::{Button, LinearLayout, TextView, TextArea}; use cursive_core::traits::Boxable; let linear_layout = LinearLayout::horizontal() .child(TextView::new("Top of the page")) .child(TextArea::new().fixed_size((20, 5))) .child(Button::new("Ok", |s| s.quit()));
Implementations
impl LinearLayout
[src]
pub fn new(orientation: Orientation) -> LinearLayout
[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) -> LinearLayout
[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>(self, view: V) -> LinearLayout where
V: 'static + IntoBoxedView,
[src]
V: 'static + IntoBoxedView,
Adds a child to the layout.
Chainable variant.
pub fn add_child<V>(&mut self, view: V) where
V: 'static + IntoBoxedView,
[src]
V: 'static + IntoBoxedView,
Adds a child to the layout.
pub fn insert_child<V>(&mut self, i: usize, view: V) where
V: 'static + IntoBoxedView,
[src]
V: 'static + IntoBoxedView,
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 set_focus_index(&mut self, index: usize) -> Result<(), ()>
[src]
Attemps to set the focus on the given child.
Returns Err(())
if index >= self.len()
, or if the view at the
given index does not accept focus.
pub fn vertical() -> LinearLayout
[src]
Creates a new vertical layout.
pub fn horizontal() -> LinearLayout
[src]
Creates a new horizontal layout.
pub fn get_child(&self, i: usize) -> Option<&(dyn View + 'static)>
[src]
Returns a reference to a child.
pub fn get_child_mut(&mut self, i: usize) -> Option<&mut (dyn View + 'static)>
[src]
Returns a mutable reference to a child.
pub fn remove_child(&mut self, i: usize) -> Option<Box<dyn View + 'static>>
[src]
Removes a child.
If i
is within bounds, the removed child will be returned.
