Implementations

impl ChangeFlags

pub const FinalTransformation: ChangeFlags

Use this flag for a property type that affects the final transformation of a node and its descendants.

For a 2D node, this flag causes Kanzi to:

• Run Node2D::updateRender on the node and its descendants. This updates the transformation of the nodes.
• Draw all nodes.

For a 3D node, this flag causes Kanzi to:

• Update the transformation of the node and its descendants.
• Draw all nodes.

For example, Node::ActualWidthProperty, Node2D::RenderTransformationProperty, and Node3D::RenderTransformationProperty use this flag.

pub const Measure: ChangeFlags

Use this flag for a property type that affects the size of the node as reported by the node itself, or the size and position of the node with respect to other nodes.

For a 2D node, this flag causes Kanzi to:

• Run Node2D::measure on the node.
• If the measured size of the node changed, run Node2D::measure on the parent of the node.
• If the measured size of the parent node changed, run Node2D::measure on the parent of the parent node, and so on.
• Run Node2D::arrange and Node2D::updateRender on the node, all the changed ancestor nodes, and their descendants. If the transform of a node changed, Node2D::updateRender recalculates the transformations.
• Draw all nodes.

For a 3D node, this flag causes Kanzi to:

• Run Node3D::measure on the node.
• If the measured size of the node changed, run Node3D::measure on the parent of the node.
• If the measured size of the parent node changed, run Node3D::measure on the parent of the parent node, and so on.
• Run Node3D::arrange on the node, all the changed ancestor nodes, and their descendants.
• Recalculate the transformations of the nodes.
• Draw all nodes.

For example, properties that set the size, margins, padding, and alignment of a node, use this flag.

pub const ParentMeasure: ChangeFlags

Use this flag for a property type that affects the layout of the parent node of a node. This flag causes Kanzi to set the ChangeFlags::Measure flag on the parent of the node.

For example, the DockLayoutConcept::SideProperty, GridLayoutConcept::ColumnProperty, and GridLayoutConcept::RowProperty use this flag.

pub const Arrange: ChangeFlags

Use this flag for a property type that affects the need to arrange the layout of a node.

For a 2D node, this flag causes Kanzi to:

• Run Node2D::arrange on the node and its descendants.
• Run Node2D::updateRender on the node and its descendants. If the transform of a node changed, Node2D::updateRender recalculates the transformation.
• Draw all nodes.

For a 3D node, this flag causes Kanzi to:

• Run Node3D::arrange on the node and its descendants.
• Recalculate the transformations of the node and its descendants.
• Draw all nodes.

All property types that have the ChangeFlags::Measure set, run the arrange phase on those nodes whose measurements changed.

pub const Render: ChangeFlags

Use this flag for a property type that changes the rendering parameters of a 2D node but does not affect the layout.

For a 2D node, this flag causes Kanzi to:

• Run Node2D::updateRender on the node and its descendants. If the transform of a node changed, Node2D::updateRender recalculates the transformation.
• Draw all nodes.

For a property type that changes the rendering parameters of a 3D node but does not affect the layout, use ChangeFlags::Draw instead of ChangeFlags::Render.

For example, these properties use the ChangeFlags::Render flag:

• Node2D::RenderTransformationProperty and Node3D::RenderTransformationProperty
• Brush properties
• Properties of 2D effects, such as BlurEffect2D and MaskEffect2D

pub const Draw: ChangeFlags

Use this flag for a property type that affects the drawing of a node.

This flag causes Kanzi to draw all nodes.

For example, most material properties use this flag.

pub const Constraint: ChangeFlags

Property type with this flag informs that constraints are in use.

The bitwise or (|) of the bits in two flags values.

pub fn remove(&mut self, other: ChangeFlags)

This method is not equivalent to self & !other when other has unknown bits set. remove won’t truncate other, but the ! operator will.

pub fn set(&mut self, other: ChangeFlags, value: bool)

The bitwise or (|) of the bits in two flags values.

pub const fn difference(self, other: ChangeFlags) -> ChangeFlags

The intersection of a source flags value with the complement of a target flags value (&!).

The bitwise exclusive-or (^) of the bits in two flags values.

pub const fn complement(self) -> ChangeFlags

The bitwise negation (!) of the bits in a flags value, truncating the result.

impl ChangeFlags

pub const fn iter(&self) -> Iter<ChangeFlags>

Yield a set of contained flags values.

Each yielded flags value will correspond to a defined named flag. Any unknown bits will be yielded together as a final flags value.

pub const fn iter_names(&self) -> IterNames<ChangeFlags>

Yield a set of contained named flags values.

This method is like iter, except only yields bits in contained named flags. Any unknown bits, or bits not corresponding to a contained flag will not be yielded.
