Struct cursive::views::ScrollView

pub struct ScrollView<V> { /* fields omitted */ }

Wraps a view in a scrollable area.

Methods

impl<V> ScrollView<V> where
    V: View, 

pub fn new(inner: V) -> Self

Creates a new ScrollView around view.

pub fn content_viewport(&self) -> Rect

Returns the viewport in the inner content.

pub fn set_scroll_strategy(&mut self, strategy: ScrollStrategy)

Defines the way scrolling is adjusted on content or size change.

The scroll strategy defines how the scrolling position is adjusted when the size of the view or the content change.

It is reset to ScrollStrategy::KeepRow whenever the user scrolls manually.

pub fn scroll_strategy(self, strategy: ScrollStrategy) -> Self

Defines the way scrolling is adjusted on content or size change.

Chainable variant.

pub fn set_show_scrollbars(&mut self, show_scrollbars: bool)

Control whether scroll bars are visibile.

Defaults to true.

pub fn show_scrollbars(self, show_scrollbars: bool) -> Self

Control whether scroll bars are visibile.

Chainable variant

pub fn set_offset<S>(&mut self, offset: S) where
    S: Into<Vec2>, 

Sets the scroll offset to the given value

pub fn set_scroll_y(&mut self, enabled: bool)

Controls whether this view can scroll vertically.

Defaults to true.

pub fn set_scroll_x(&mut self, enabled: bool)

Controls whether this view can scroll horizontally.

Defaults to false.

pub fn scroll_y(self, enabled: bool) -> Self

Controls whether this view can scroll vertically.

Defaults to true.

Chainable variant.

pub fn scroll_x(self, enabled: bool) -> Self

Controls whether this view can scroll horizontally.

Defaults to false.

Chainable variant.

pub fn scroll_to_top(&mut self)

Programmatically scroll to the top of the view.

pub fn scroll_to_bottom(&mut self)

Programmatically scroll to the bottom of the view.

pub fn scroll_to_left(&mut self)

Programmatically scroll to the leftmost side of the view.

pub fn scroll_to_right(&mut self)

Programmatically scroll to the rightmost side of the view.

pub fn into_inner(self) -> V

Returns the wrapped view.

pub fn get_inner(&self) -> &V

Gets access to the inner view.

pub fn get_inner_mut(&mut self) -> &mut V

Gets mutable access to the inner view.

Trait Implementations

impl<V> View for ScrollView<V> where
    V: View, 

fn draw(&self, printer: &Printer)

Draws the view with the given printer (includes bounds) and focus.

fn on_event(&mut self, event: Event) -> EventResult

Called when an event is received (key press, mouse event, ...).

fn layout(&mut self, size: Vec2)

Called once the size for this view has been decided.

fn needs_relayout(&self) -> bool

Should return true if the view content changed since the last call to layout().

fn required_size(&mut self, constraint: Vec2) -> Vec2

Returns the minimum size the view requires with the given restrictions.

fn call_on_any<'a>(&mut self, selector: &Selector, cb: AnyCb<'a>)

Runs a closure on the view identified by the given selector.

fn focus_view(&mut self, selector: &Selector) -> Result<(), ()>

Moves the focus to the view identified by the given selector.

fn take_focus(&mut self, source: Direction) -> bool

This view is offered focus. Will it take it?

fn important_area(&self, size: Vec2) -> Rect

What part of the view is important and should be visible?
