A Component is representing an unit that is allocated together

Fields

visit_children_item: unsafe extern "C" fn(_: Pin<VRef<'_, ComponentVTable>>, index: isize, order: TraversalOrder, visitor: VRefMut<'_, ItemVisitorVTable>) -> VisitChildrenResult

Visit the children of the item at index index. Note that the root item is at index 0, so passing 0 would visit the item under root (the children of root). If you want to visit the root item, you need to pass -1 as an index.

layout_info: unsafe extern "C" fn(_: Pin<VRef<'_, ComponentVTable>>) -> LayoutInfo

Returns the layout info for this component

compute_layout: unsafe extern "C" fn(_: Pin<VRef<'_, ComponentVTable>>)

Will compute the layout of

input_event: unsafe extern "C" fn(_: Pin<VRef<'_, ComponentVTable>>, _: MouseEvent, _: &ComponentWindow, _: &Pin<VRef<'_, ComponentVTable>>) -> InputEventResult

input event

key_event: unsafe extern "C" fn(_: Pin<VRef<'_, ComponentVTable>>, _: &KeyEvent, _: &ComponentWindow) -> KeyEventResult

key event

focus_event: unsafe extern "C" fn(_: Pin<VRef<'_, ComponentVTable>>, _: &FocusEvent, _: &ComponentWindow) -> FocusEventResult

Event sent to transfer focus between items or to communicate window focus change.

Implementations

impl ComponentVTable

pub fn new<T: Component>() -> Self

Create a vtable suitable for a given type implementing the trait.

Trait Implementations

impl VTableMeta for ComponentVTable

type VTable = ComponentVTable

That's the VTable itself (so most likely Self)

type Target = ComponentTO

That's the trait object that implements the functions
