Struct re_viewport::Viewport

pub struct Viewport<'a> {
    pub blueprint: &'a ViewportBlueprint,
    pub tree: Tree<SpaceViewId>,
    pub tree_edited: bool,
    tree_action_receiver: Receiver<TreeAction>,
    tree_action_sender: Sender<TreeAction>,
}

Defines the layout of the Viewport

Fields

blueprint: &'a ViewportBlueprint

The blueprint that drives this viewport. This is the source of truth from the store for this frame.

tree: Tree<SpaceViewId>

The [egui_tiles::Tree] tree that actually manages blueprint layout. This tree needs to be mutable for things like drag-and-drop and is ultimately saved back to the store. at the end of the frame if edited.

tree_edited: bool

Should be set to true whenever a tree modification should be back-ported to the blueprint store. That should only happen as a result of a user action.

tree_action_receiver: Receiver<TreeAction>

Actions to perform at the end of the frame.

We delay any modifications to the tree until the end of the frame, so that we don’t mutate something while inspecting it.

tree_action_sender: Sender<TreeAction>

Tree action sender

Used to pass along TabViewer.

Implementations

impl<'a> Viewport<'a>

pub fn new( blueprint: &'a ViewportBlueprint, space_view_class_registry: &SpaceViewClassRegistry, tree_action_receiver: Receiver<TreeAction>, tree_action_sender: Sender<TreeAction> ) -> Self

pub fn viewport_ui( &mut self, ui: &mut Ui, ctx: &'a ViewerContext<'_>, view_states: &mut ViewStates )

pub fn on_frame_start(&mut self, ctx: &ViewerContext<'_>)

pub fn update_and_sync_tile_tree_to_blueprint(self, ctx: &ViewerContext<'_>)

Process any deferred TreeActions and then sync to blueprint

pub fn is_item_valid( &self, store_context: &StoreContext<'_>, item: &Item ) -> bool

If false, the item is referring to data that is not present in this blueprint.
