The implementation of the TouchArea element

Fields

x: Property<f32>

y: Property<f32>

width: Property<f32>

height: Property<f32>

pressed: Property<bool>

FIXME: We should anotate this as an "output" property.

pressed_x: Property<f32>

FIXME: there should be just one property for the point istead of two. Could even be merged with pressed in a Property<Option> (of course, in the implementation item only, for the compiler it would stay separate properties)

pressed_y: Property<f32>

mouse_x: Property<f32>

FIXME: should maybe be as parameter to the mouse event instead. Or at least just one property

mouse_y: Property<f32>

clicked: Signal<()>

cached_rendering_data: CachedRenderingData

FIXME: remove this

Implementations

impl TouchArea

pub const FIELD_OFFSETS: TouchAreaFieldsOffsets

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

Trait Implementations

impl Default for TouchArea

fn default() -> TouchArea

Returns the "default value" for a type.

impl HasStaticVTable<ItemVTable> for TouchArea

fn static_vtable() -> &'static ItemVTable

Safety: must be a valid VTable for Self

impl Item for TouchArea

fn init(self: Pin<&Self>, _window: &ComponentWindow)

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 geometry(self: Pin<&Self>) -> Rect

Returns the geometry of this item (relative to its parent item)

fn rendering_primitive(
    self: Pin<&Self>,
    _window: &ComponentWindow
) -> HighLevelRenderingPrimitive

Return the rendering primitive used to display this item. This should depend on only rarely changed properties as it typically contains data uploaded to the GPU.

fn rendering_variables(
    self: Pin<&Self>,
    _window: &ComponentWindow
) -> SharedArray<RenderingVariable>

Return the variables needed to render the graphical primitives of this item. These are typically variables that do not require uploading any data sets to the GPU and can instead be represented using uniforms.

fn layouting_info(self: Pin<&Self>, _window: &ComponentWindow) -> LayoutInfo

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

fn input_event(
    self: Pin<&Self>,
    event: MouseEvent,
    _window: &ComponentWindow,
    _app_component: ComponentRefPin<'_>
) -> InputEventResult

input event

fn key_event(
    self: Pin<&Self>,
    _: &KeyEvent,
    _window: &ComponentWindow
) -> KeyEventResult

fn focus_event(self: Pin<&Self>, _: &FocusEvent, _window: &ComponentWindow)

impl ItemConsts for TouchArea

const cached_rendering_data_offset: FieldOffset<TouchArea, CachedRenderingData>

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

impl<'__dummy_lifetime> Unpin for TouchArea where
    __MustNotImplUnpin<'__dummy_lifetime>: Unpin,
