Expand description

An Element is an instantiation of a Component

Fields

id: String

The id as named in the original .60 file.

Note that it can only be used for lookup before inlining. After inlining there can be duplicated id in the component. The id are then re-assigned unique id in the assign_id pass

base_type: Typebindings: BindingsMap

Currently contains also the callbacks. FIXME: should that be changed?

property_analysis: RefCell<HashMap<String, PropertyAnalysis>>children: Vec<ElementRc>enclosing_component: Weak<Component>

The component which contains this element.

property_declarations: BTreeMap<String, PropertyDeclaration>named_references: NamedReferenceContainer

Main owner for a reference to a property.

repeated: Option<RepeatedElementInfo>

Tis element is part of a `for in :

states: Vec<State>transitions: Vec<Transition>child_of_layout: bool

true when this item’s geometry is handled by a layout

layout_info_prop: Option<(NamedReference, NamedReference)>

The property pointing to the layout info. (horizontal, vertical)

is_flickable_viewport: bool

true if this Element is the fake Flickable viewport

item_index: OnceCell<usize>

This is the component-local index of this item in the item tree array. It is generated after the last pass and before the generators run.

node: Option<Element>

The AST node, if available

Implementations

[src]

impl Element

[src]

pub fn from_node(
 node: Element,
 id: String,
 parent_type: Type,
 component_child_insertion_point: &mut Option<(ElementRc, ChildrenPlaceholder )>,
 diag: &mut BuildDiagnostics,
 tr: &TypeRegister
) -> ElementRc

[src]

pub fn lookup_property<'a>(&self, name: &'a str) -> PropertyLookupResult<'a>

Return the type of a property in this element or its base, along with the final name, in case the provided name points towards a property alias. Type::Invalid is returned if the property does not exist.
