pub struct Ui { /* private fields */ }

The main access point for manipulating the UI.

Implementations

impl Ui

pub fn poke<A: Any>(&mut self, node: Id, payload: &mut A) -> bool

Send an arbitrary payload to a widget. The type and interpretation of the payload depends on the specific target widget.

pub fn add<W>(&mut self, widget: W, children: &[Id]) -> Idwhere
    W: Widget + 'static,

Put a widget in the graph and add its children. Returns newly allocated id for the node.

pub fn set_root(&mut self, root: Id)

pub fn set_focus(&mut self, node: Option<Id>)

Set the focused widget.

pub fn add_listener<A, F>(&mut self, node: Id, f: F)where
    A: Any,
    F: FnMut(&mut A, ListenerCtx<'_>) + 'static,

Add a listener that expects a specific type.

pub fn append_child(&mut self, node: Id, child: Id)

Add a child dynamically, in the last position.

pub fn add_before(&mut self, node: Id, sibling: Id, child: Id)

Add a child dynamically, before the given sibling.

pub fn remove_child(&mut self, node: Id, child: Id)

Remove a child.

Can panic if child is not a valid child. The child is not deleted, but can be added again later. The listeners for the child are not cleared.

pub fn delete_child(&mut self, node: Id, child: Id)

Delete a child.

Can panic if child is not a valid child. Deletes the subtree rooted at the child, drops those widgets, and clears all listeners. The id of the child may be reused; callers should take care not to use the child id in any way afterwards.
