The implementation of the TouchArea
element
Fields
x: Property<Coord>
y: Property<Coord>
width: Property<Coord>
height: Property<Coord>
enabled: Property<bool>
pressed: Property<bool>
FIXME: We should annotate this as an “output” property.
has_hover: Property<bool>
pressed_x: Property<Coord>
FIXME: there should be just one property for the point instead of two.
Could even be merged with pressed in a Property<Option
pressed_y: Property<Coord>
mouse_x: Property<Coord>
FIXME: should maybe be as parameter to the mouse event instead. Or at least just one property
mouse_y: Property<Coord>
mouse_cursor: Property<MouseCursor>
clicked: Callback<VoidArg>
moved: Callback<VoidArg>
pointer_event: Callback<(PointerEvent,)>
cached_rendering_data: CachedRenderingData
FIXME: remove this

sourceimpl HasStaticVTable<ItemVTable> for TouchArea
impl HasStaticVTable<ItemVTable> for TouchArea
sourcefn static_vtable() -> &'static ItemVTable
fn static_vtable() -> &'static ItemVTable
Safety: must be a valid VTable for Self
sourceimpl Item for TouchArea
impl Item for TouchArea
sourcefn init(self: Pin<&Self>, _window: &WindowRc)
fn init(self: Pin<&Self>, _window: &WindowRc)
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. Read more
sourcefn geometry(self: Pin<&Self>) -> Rect
fn geometry(self: Pin<&Self>) -> Rect
Returns the geometry of this item (relative to its parent item)
sourcefn layout_info(
self: Pin<&Self>,
_orientation: Orientation,
_window: &WindowRc
) -> LayoutInfo
fn layout_info(
self: Pin<&Self>,
_orientation: Orientation,
_window: &WindowRc
) -> LayoutInfo
We would need max/min/preferred size, and all layout info
sourcefn input_event_filter_before_children(
self: Pin<&Self>,
event: MouseEvent,
window: &WindowRc,
_self_rc: &ItemRc
) -> InputEventFilterResult
fn input_event_filter_before_children(
self: Pin<&Self>,
event: MouseEvent,
window: &WindowRc,
_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. Read more

window: &WindowRc,
_self_rc: &ItemRc
) -> InputEventResult
Handle input event for mouse and touch event
