Options for AnchorMode::transform.

Variants

None

Widget does not copy any position from the anchor widget.

InnerOffset(AnchorOffset)

The layer widget is translated so that a point in the layer widget outer-bounds aligns with a point in the anchor widget inner-bounds.

InnerBorderOffset(AnchorOffset)

The layer widget is translated so that a point in the layer widget outer-bounds aligns with a point in the anchor widget fill area (inside the border offset).

OuterOffset(AnchorOffset)

The layer widget is translated so that a point in the layer widget outer-bounds aligns with a point in the anchor widget outer-bounds.

InnerTransform

The full inner transform of the anchor object is applied to the widget.

InnerBorderTransform

The full inner transform of the anchor object is applied to the widget plus the border widths offset.

OuterTransform

The full outer transform of the anchor object is applied to the widget.

CursorOnce

The layer widget is translated on the first layout to be at the cursor position.

Fields

offset: AnchorOffset

The anchor offset place point is resolved in the cursor icon size (approximate).

include_touch: bool

If the latest touch position counts as a cursor.

If true the latest position between mouse move and touch start or move is used, if false only the latest mouse position is used. Only active touch points count, that is touch start or move events only.

bounds: Option<SideOffsets>

If set defines the offset from the anchor widget inner bounds that is the allowed area for the layer widget origin.

Negative offsets are inside the inner bounds, positive outside.

Cursor

The layer widget is translated to follow the cursor position.

The anchor offset place point is resolved in the cursor icon size (approximate).

Fields

offset: AnchorOffset

The anchor offset place point is resolved in the cursor icon size (approximate), or in touch point pixel for touch positions.

include_touch: bool

If the latest touch position counts as a cursor.

If true the latest position between mouse move and touch start or move is used, if false only the latest mouse position is used. Only active touch points count, that is touch start or move events only. In case multiple touches are active only the first one counts.

bounds: Option<SideOffsets>

If set defines the offset from the anchor widget inner bounds that is the allowed area for the layer widget origin.

Negative offsets are inside the inner bounds, positive outside.

Trait Implementations

impl Clone for AnchorTransform

fn clone(&self) -> AnchorTransform

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for AnchorTransform

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for AnchorTransform

fn deserialize<__D>( __deserializer: __D, ) -> Result<AnchorTransform, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<P, O> From<(P, O)> for AnchorTransform

where P: Into<Point>, O: Into<Point>,

fn from(inner_offset: (P, O)) -> AnchorTransform

InnerOffset.

impl From<AnchorOffset> for AnchorTransform

fn from(inner_offset: AnchorOffset) -> AnchorTransform

InnerOffset.

impl From<AnchorTransform> for AnchorMode

fn from(transform: AnchorTransform) -> AnchorMode

Custom transform, all else default.

impl IntoVar<AnchorMode> for AnchorTransform

fn into_var(self) -> <AnchorTransform as IntoVar<AnchorMode>>::Var

Custom transform, all else default.

type Var = LocalVar<AnchorMode>

Variable type that will wrap the T value.

where Self: Sized,

Converts into BoxedVar<T>.

impl<P, O> IntoVar<AnchorTransform> for (P, O)

where P: Into<Point>, O: Into<Point>,

fn into_var(self) -> <(P, O) as IntoVar<AnchorTransform>>::Var

InnerOffset.
