Struct fungui::Manager

pub struct Manager<E: Extension> { /* private fields */ }

Stores loaded nodes and manages the layout.

Implementations

impl<E: Extension> Manager<E>

pub fn new() -> Manager<E>

Creates a new manager with an empty root node.

pub fn add_layout_engine<F, L>(&mut self, creator: F)where
    F: Fn() -> L + 'static,
    L: LayoutEngine<E> + 'static,

Adds a new function that can be used to create a layout engine.

A layout engine is used to position elements within an element.

The layout engine can be selected by using the layout attribute.

pub fn add_func_raw<F>(&mut self, name: &'static str, func: F)where
    F: for<'a> Fn(&mut (dyn Iterator<Item = FResult<'a, Value<E>>> + 'a)) -> FResult<'a, Value<E>> + 'static,

Add a function that can be called by style rules

Arguments are only parsed when obtained from the iterator making unused parameters cheap.

pub fn add_node_str<'a>(&mut self, node: &'a str) -> Result<(), PError<'a>>

Adds the node to the root node of this manager.

The node is created from the passed string. See from_str

pub fn add_node(&mut self, node: Node<E>)

Adds the node to the root node of this manager

pub fn remove_node(&mut self, node: Node<E>)

Removes the node from the root node of this manager

pub fn query(&self) -> Query<'_, E>

Starts a query from the root of this manager

pub fn query_at(&self, x: i32, y: i32) -> Query<'static, E>

Starts a query looking for elements at the target location.

pub fn load_styles<'a>(
    &mut self,
    name: &str,
    style_rules: &'a str
) -> Result<(), PError<'a>>

Loads a set of styles from the given string.

The name can be used to remove the loaded styles later

pub fn remove_styles(&mut self, name: &str)

Removes the set of styles with the given name

pub fn layout(&mut self, width: i32, height: i32)

Positions the nodes in this manager.

This will update nodes based on their properties and then position them based on their selected layout.

pub fn render<V>(&mut self, visitor: &mut V)where
    V: RenderVisitor<E>,

Renders the nodes in this manager by passing the draw position/size and style properties to the visitor
