Struct PluginManager 

pub struct PluginManager { /* private fields */ }

Manages UI plugins and the widget type registry.

Plugins are stored in registration order. The widget type registry is populated during add_plugin and provides O(1) dispatch for render/measure/event operations.

Implementations

impl PluginManager

pub fn new() -> Self

Create a new empty plugin manager.

pub fn add_plugin<P: UiPlugin>(&mut self, plugin: P) -> PluginHandle<P>

Add a plugin, register its widgets, and return a proof handle.

Panics

Panics if a plugin of the same concrete type is already registered.

pub fn handle<P: UiPlugin>(&self) -> Option<PluginHandle<P>>

Get a handle for an already-registered plugin by type.

Returns Some(PluginHandle) if the plugin is registered, None otherwise. This is useful for obtaining handles to auto-registered plugins (e.g., DockingPlugin, ScrollPlugin).

pub fn get<P: UiPlugin>(&self) -> Option<&P>

Get a reference to a registered plugin by type.

pub fn get_mut<P: UiPlugin>(&mut self) -> Option<&mut P>

Get a mutable reference to a registered plugin by type.

pub fn widget_registry(&self) -> &WidgetTypeRegistry

Get a reference to the widget type registry.

pub fn post_layout(&mut self, tree: &mut UiTree)

Dispatch post_layout to all plugins in registration order.

pub fn update(&mut self, dt: f32, tree: &mut UiTree)

Dispatch update to all plugins in registration order.

pub fn handle_event( &mut self, event: &UiInputEvent, ctx: &mut PluginEventContext<'_>, ) -> bool

Dispatch an event to all plugins in order. Returns true if consumed.

pub fn plugin_count(&self) -> usize

Number of registered plugins.
