Struct polyhorn_android::raw::OpaqueContainer

pub struct OpaqueContainer(_, _, _);

Opaque wrapper around a container with two optional layouts attached. If both are given, the first refers to the container's layout itself, whereas the second refers to the container's content layout. These can be different when working with scroll views for example, which are essentially treated as two adjacent nodes in the layout tree.

Implementations

impl OpaqueContainer

pub fn new<T>(
    layout: LayoutNode,
    content_layout: Option<LayoutNode>,
    view: T
) -> OpaqueContainer where
    T: Container, 

Returns a new opaque container with the given layout, view and optionally a separate content layout.

pub unsafe fn activity(env: *mut c_void, object: *mut c_void) -> OpaqueContainer

pub fn layout(&self) -> Option<&LayoutNode>

Returns the layout of this container (if applicable).

pub fn content_layout(&self) -> Option<&LayoutNode>

Returns the content layout of this container (if applicable). Returns None if not applicable, even if the container has a regular layout.

pub fn container(&self) -> &dyn Container

Returns the container wrapped in this opaque container.

pub fn downcast_mut<T>(&mut self) -> Option<&mut T> where
    T: 'static, 

Attempts to downcast this container to a concrete type and if successful, returns a mutable reference.
