Implementations
impl dyn WidgetObj[src]
pub fn is<__T: WidgetObj>(&self) -> bool[src]

pub fn downcast<__T: WidgetObj>(self: Box<Self>) -> Result<Box<__T>, Box<Self>>[src]
Returns a boxed object from a boxed trait object if the underlying object is of type
__T. Returns the original boxed trait if it isn't.
pub fn downcast_rc<__T: WidgetObj>(self: Rc<Self>) -> Result<Rc<__T>, Rc<Self>>[src]
Returns an Rc-ed object from an Rc-ed trait object if the underlying object is of
type __T. Returns the original Rc-ed trait if it isn't.
pub fn downcast_ref<__T: WidgetObj>(&self) -> Option<&__T>[src]
Returns a reference to the object within the trait object if it is of type __T, or
None if it isn't.
pub fn downcast_mut<__T: WidgetObj>(&mut self) -> Option<&mut __T>[src]
Returns a mutable reference to the object within the trait object if it is of type
__T, or None if it isn't.
