def add_element(self: Any, element: UIElement, layer: LayerType = None) -> Any

Add a UI element to the appropriate layer.

def remove_element(self: Any, element: UIElement) -> Any

Remove a UI element from all layers.

def clear_layer(self: Any, layer: LayerType) -> Any

Clear all elements from a specific layer.

def clear_all(self: Any) -> Any

Clear all elements from all layers.

def _determine_layer(self: Any, element: UIElement) -> LayerType

Determine the appropriate render layer for a UI element.

def determine_list_layers(self: Any, element_list: List[UIElement]) -> Dict[LayerType, List[UIElement]]

Classify a list of elements by layer.

def get_elements_in_order_from(self: Any, elements: List[UIElement]) -> List[UIElement]

Get elements in correct render order from a list, using layer classification.

def get_elements_in_order(self: Any) -> List[UIElement]
