virtual void iview::CAffineTransformation2dShape::Draw ( QPainter & drawContext ) const

virtual

Draw this shape using draw context.

Implements iview::IVisualizable.

◆ GetControlPoints()

static const ControlPoints & iview::CAffineTransformation2dShape::GetControlPoints ( )

staticprotected

Get access to relative positions of control points.

◆ GetScreenPoints()

void iview::CAffineTransformation2dShape::GetScreenPoints	(	const ControlPoints &	points,
		ControlPoints &	result ) const

protected

Transform control points from logical to screen coordinates.

Parameters

points	list of input points.
result	list of output points.

◆ GetTransformedPoints()

static void iview::CAffineTransformation2dShape::GetTransformedPoints	(	const ControlPoints &	points,
		ControlPoints &	result,
		const i2d::CAffineTransformation2d &	transformation )

staticprotected

Transform control points from logical to screen coordinates.

Parameters

points	list of input points.
result	list of output points.
transformation	transformation to be applied for each point.

◆ IsTouched()

virtual TouchState iview::CAffineTransformation2dShape::IsTouched ( istd::CIndex2d position ) const

virtual

Check, if any shape is touched.

When shape is touched, it return also pointer to this shape.

Returns: touch state for the shape, or iview::IInteractiveShape::TS_NONE, when nothing found.

Implements iview::ITouchable.

◆ OnModelAttached()

virtual bool iview::CAffineTransformation2dShape::OnModelAttached	(	imod::IModel *	modelPtr,
		istd::IChangeable::ChangeSet &	changeMask )

virtual

This call back function will be called, if an observable object is about to be attached.

This function returns a true, if observable object is accepted by the implementation logic of the observer, otherwise returns false.

Parameters

modelPtr	pointer to model object being attached.
changeMask	output parameter returning set of change ID's will be accepted. returns a `false`.

Reimplemented from iview::CInteractiveShapeBase.

◆ SetActiveControlPoints()

void iview::CAffineTransformation2dShape::SetActiveControlPoints ( ControlPoint points = ALL_POINTS )

Set control points that can be moved by the user (OR'ed ControlPoints).

◆ SetLogDragPosition()

virtual void iview::CAffineTransformation2dShape::SetLogDragPosition ( const i2d::CVector2d & position )

protectedvirtual

Implements iview::CInteractiveShapeBase.
