Required methods

fn id(&self) -> E::WidgetID

fn render(&self, l: Link<E>, r: &mut RenderLink<E>) -> bool

this method should not be called from external, rather [Link::render][../link/struct.Link.html#method.render]

fn event(&self, l: Link<E>, e: (EEvent<E>, &Bounds, u64))

this method should not be called from external, rather [Link::event][../link/struct.Link.html#method.event]

fn size(&self, l: Link<E>) -> ESize<E>

this method should not be called from external, rather [Link::size][../link/struct.Link.html#method.size]

fn childs(&self) -> usize

fn child<'s>(&'s self, i: usize) -> Result<Resolvable<'s, E>, ()> where
    'w: 's, 

fn into_child(self: Box<Self>, i: usize) -> Result<Resolvable<'w, E>, ()>

fn into_childs(self: Box<Self>) -> Vec<Resolvable<'w, E>>

fn _trace_bounds(
    &self,
    l: Link<E>,
    i: usize,
    b: &Bounds,
    force: bool
) -> Result<Bounds, ()>

fn focusable(&self) -> bool

should the widget be focusable, regularly true for interactive widgets, false for layouts

Methods

impl<'w, E> dyn Widget<'w, E> where
    E: Env, [src]

pub fn is_type<T>(&self) -> bool where
    T: Statize, [src]

pub fn _downcast_ref<'s, 'd, T>(&'s self) -> Option<&'s T> where
    T: Statize + 'd,
    'w: 's,
    'w: 'd,
    'd: 's, [src]

pub fn downcast_ref<'s, 'd, T>(&'s self) -> Option<&'s T> where
    T: Statize + 'd,
    'w: 's,
    'w: 'd,
    'd: 's, [src]

downcast the current widget to a specific implementation

pub fn _traitcast_ref<'s, 'd, T: ?Sized>(&'s self) -> Option<&'s T> where
    T: Statize + 'd,
    'w: 's,
    'w: 'd,

pub fn traitcast_ref<'s, 'd, T: ?Sized>(&'s self) -> Option<&'s T> where
    T: Statize + 'd,
    'w: 's,
    'w: 'd,
    'd: 's, [src]

this will definetly cause UB and delet ur computer
