Member Function Documentation

virtual void iview::CAffineTransformation2dShape::BeginLogDrag ( const i2d::CVector2d reference)
protectedvirtual
virtual i2d::CRect iview::CAffineTransformation2dShape::CalcBoundingBox ( ) const
protectedvirtual

Calculate bounding box.

You have to implement this method in your shapes implementations.

Implements iview::CShapeBase.

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

Draw this shape using draw context.

Implements iview::IVisualizable.

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

Generate transformed points using given transformation.

If there is no transformation, generate default Cartesian coordinate system corner points: begin, X axis end and Y axis end.

Parameters
sizeLength of both axes
void iview::CAffineTransformation2dShape::GetScreenPoints ( const ControlPoints points,
ControlPoints result 
) const
protected

Transform control points from logical to screen coordinates.

Parameters
transformLogToScreenTransform assigned to the view
static void iview::CAffineTransformation2dShape::GetTransformedPoints ( const ControlPoints points,
ControlPoints result,
const i2d::CAffineTransformation2d transformation 
)
staticprotected
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.

Reimplemented from iview::CShapeBase.

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
modelPtrpointer to model object being attached.
changeMaskoutput parameter returning set of change ID's will be accepted. returns a false.

Reimplemented from iview::CInteractiveShapeBase.

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

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

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