Implementations

impl DropArea

pub const FIELD_OFFSETS: DropAreaFieldsOffsets

Return a struct containing the offset of for the fields of this struct

impl DropArea

pub fn enabled(self: Pin<&Self>) -> bool

pub fn contains_drag(self: Pin<&Self>) -> bool

Trait Implementations

impl Default for DropArea

fn default() -> DropArea

Returns the “default value” for a type.

impl HasStaticVTable<ItemVTable> for DropArea

fn static_vtable() -> &'static ItemVTable

Safety: must be a valid VTable for Self

impl Item for DropArea

fn init(self: Pin<&Self>, _self_rc: &ItemRc)

This function is called by the run-time after the memory for the item has been allocated and initialized. It will be called before any user specified bindings are set.

fn layout_info( self: Pin<&Self>, _: Orientation, _window_adapter: &Rc<dyn WindowAdapter>, _self_rc: &ItemRc, ) -> LayoutInfo

We would need max/min/preferred size, and all layout info

fn input_event_filter_before_children( self: Pin<&Self>, _: &MouseEvent, _window_adapter: &Rc<dyn WindowAdapter>, _self_rc: &ItemRc, ) -> InputEventFilterResult

Event handler for mouse and touch event. This function is called before being called on children. Then, depending on the return value, it is called for the children, and their children, then Self::input_event is called on the children, and finally Self::input_event is called on this item again.

fn input_event( self: Pin<&Self>, event: &MouseEvent, window_adapter: &Rc<dyn WindowAdapter>, _self_rc: &ItemRc, ) -> InputEventResult

Handle input event for mouse and touch event

fn capture_key_event( self: Pin<&Self>, _: &KeyEvent, _window_adapter: &Rc<dyn WindowAdapter>, _self_rc: &ItemRc, ) -> KeyEventResult

Called on the parents of the focused item, allowing for global shortcuts and similar overrides of the default actions.

fn key_event( self: Pin<&Self>, _: &KeyEvent, _window_adapter: &Rc<dyn WindowAdapter>, _self_rc: &ItemRc, ) -> KeyEventResult

fn focus_event( self: Pin<&Self>, _: &FocusEvent, _window_adapter: &Rc<dyn WindowAdapter>, _self_rc: &ItemRc, ) -> FocusEventResult

fn render( self: Pin<&Self>, _: &mut &mut dyn ItemRenderer, _self_rc: &ItemRc, _size: LogicalSize, ) -> RenderingResult

fn bounding_rect( self: Pin<&Self>, _window_adapter: &Rc<dyn WindowAdapter>, _self_rc: &ItemRc, geometry: LogicalRect, ) -> LogicalRect

fn clips_children(self: Pin<&Self>) -> bool

impl ItemConsts for DropArea

const cached_rendering_data_offset: FieldOffset<DropArea, CachedRenderingData>

offset in bytes from the *const ItemImpl. isize::MAX means None

impl<'__dummy_lifetime> Unpin for DropArea

where __MustNotImplUnpin<'__dummy_lifetime>: Unpin,
