[‘TreeItem’, ‘TreeView’]

class simvx.core.ui.tree.TreeItem(text: str = '', children: list[simvx.core.ui.tree.TreeItem] | None = None, expanded: bool = True, data: Any = None)

Data node for a tree hierarchy.

Attributes: text: Display text for this item. children: Child items. expanded: Whether children are visible. data: Arbitrary user data attached to this item. parent: Parent TreeItem (set internally by add_child/remove_child).

Example: root = TreeItem(“Root”) root.add_child(TreeItem(“Child A”)) root.add_child(TreeItem(“Child B”, data={“key”: 42}))

Initialization

__slots__

(‘text’, ‘children’, ‘expanded’, ‘data’, ‘parent’)

add_child(item: simvx.core.ui.tree.TreeItem) → simvx.core.ui.tree.TreeItem

Add a child item and set its parent.

remove_child(item: simvx.core.ui.tree.TreeItem)

Remove a child item and clear its parent.

class simvx.core.ui.tree.TreeView(root: simvx.core.ui.tree.TreeItem | None = None, **kwargs)

Bases: simvx.core.ui.core.Control

Scrollable tree widget with expand/collapse and selection.

Renders a TreeItem hierarchy with indentation, clickable expand/collapse arrows, and selection highlight.

Example: root = TreeItem(“Scene”) root.add_child(TreeItem(“Player”)) root.add_child(TreeItem(“Enemies”, children=[ TreeItem(“Goblin”), TreeItem(“Dragon”), ]))

tree = TreeView(root=root)
tree.item_selected.connect(lambda item: print(item.text))
