std::string

getDomPath () const

Returns a DOM-style path to this node.
const Style &

getStyle () const

Returns the style elements defined on this Node but not inherited from ancestors.
void

setStyle (const Style &style)

Sets the style defined on this Node but not inherited from ancestors.
Style

calcInheritedStyle () const

void

setTransform (const mat3 &transform)

Sets the local transformation of this node.
void

unspecifyTransform ()

Removes the local transformation of this node, effectively making it the identity matrix.
mat3

getTransformInverse () const

Returns the inverse of the local transformation of this node. Returns identity if the Node 's transform isn't specified.
mat3

getTransformAbsolute () const

Returns the absolute transformation of this node, which includes inherited transformations.
mat3

getTransformAbsoluteInverse () const

Returns the inverse of the absolute transformation of this node, which includes inherited transformations.
Rectf

getBoundingBox () const

Returns the local bounding box of the Node . Calculated and cached the first time it is requested.
Rectf

getBoundingBoxAbsolute () const

Returns the absolute bounding box of the Node . Calculated and cached the first time it is requested.
Shape2d

getShape () const

Returns a Shape2d representing the node in local coordinates. Not supported for Text .
Shape2d

getShapeAbsolute () const

bool

isVisible () const

Returns whether this Node is visible, or the first among its ancestors when unspecified.
bool

isDisplayNone () const

Returns whether the Display property of this Node is set to 'None', preventing rendering of the node and its children.
