class simvx.editor.panels.scene_tree.panel.SceneTreePanel(editor_state: simvx.editor.state.State, **kwargs)

Bases: simvx.core.Control

Displays and manages the node hierarchy of the edited scene.

Features: - TreeView reflecting scene node hierarchy - Text icons per node type - Filter bar in the header - Right-click context menu (Add, Delete, Duplicate, Rename, Copy, Paste) - Keyboard shortcuts (Del, F2, Ctrl+D, Ctrl+C, Ctrl+V) - All mutations go through UndoStack via AddNodeCommand/RemoveNodeCommand - Syncs with State.selection - Add Node dialog overlay for choosing node type - Composed node navigation: double-click or Enter to “enter” a user-defined node and see its children; breadcrumb/back button to return

Signals: node_reparented: Emitted as (node, old_parent, new_parent) after reparent.

node_reparented

‘Signal(…)’

ready()

Wire up signals after the node enters the tree.

property scope_root: simvx.core.Node | None

The node whose children are currently displayed in the tree.

During play mode, shows the game tree root (read-only view). When the scope stack is empty, this is the scene root. When the user has “entered” a composed node, this is that node.

property scope_depth: int

How many levels deep we are into composed nodes.

enter_composed_node(node: simvx.core.Node)

Navigate into a composed node, showing its children as the tree root.

If the node has a source file, also opens it in the editor via state.workspace.open_script().

clear_diagnostics(node: simvx.core.Node | None = None)

Clear diagnostic badges. If node is given, clear just that node.

open_add_node_dialog()

Open the Add Node type dialog. Can be called externally (e.g. from menus).

reparent_node(node: simvx.core.Node, new_parent: simvx.core.Node)

Reparent node under new_parent with undo support.

process(dt: float)

Update child positions each frame to follow panel size.
