Member Function Documentation

virtual void iview::CPolygonShape::BeginLogDrag ( const i2d::CVector2d reference)
protectedvirtual

Reimplemented from iview::CRectControlledShapeBase.

virtual i2d::CRect iview::CPolygonShape::CalcBoundingBox ( ) const
protectedvirtual

Calculate bounding box.

You have to implement this method in your shapes implementations.

Reimplemented from iview::CRectControlledShapeBase.

Reimplemented in iview::CPolylineShape, iview::CTubePolylineShape, and iview::CSplineShape.

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

Draw this shape using draw context.

Reimplemented from iview::CRectControlledShapeBase.

virtual void iview::CPolygonShape::DrawArea ( QPainter &  drawContext) const
protectedvirtual

Reimplemented in iview::CPolylineShape.

virtual void iview::CPolygonShape::DrawCurve ( QPainter &  drawContext) const

virtual i2d::CVector2d iview::CPolygonShape::GetSegmentMiddle ( int  index) const
protectedvirtual

Reimplemented in iview::CSplineShape.

bool iview::CPolygonShape::IsAlwaysMovable ( ) const
inlinevirtual

Check if in all edit modes is this shape draggable.

Normally it is possible to drag this object only in EM_NONE mode.

Reimplemented in iview::CTubePolylineShape.

Definition at line 105 of file CPolygonShape.h.

virtual bool iview::CPolygonShape::IsCurveTouched ( istd::CIndex2d  position) const
protectedvirtual
virtual bool iview::CPolygonShape::IsDraggable ( ) const
virtual

Check if drag is enabled.

Reimplemented from iview::CInteractiveShapeBase.

bool iview::CPolygonShape::IsFirstVisible ( ) const
inlinevirtual

Check if first point is always visible as ticker.

It is used to recognize which one point is the first.

Definition at line 93 of file CPolygonShape.h.

virtual TouchState iview::CPolygonShape::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::CRectControlledShapeBase.

Reimplemented in iview::CTubePolylineShape, and iview::CPolylineShape.

virtual bool iview::CPolygonShape::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.

Reimplemented in iview::CPolylineShape, and iview::CSplineShape.

virtual bool iview::CPolygonShape::OnMouseButton ( istd::CIndex2d  position,
Qt::MouseButton  buttonType,
bool  downFlag 
)
virtual

It is called, when mouse button is pushed down or up on this object.

Parameters
position- position of mouse pointer on client area (picture coords).
downFlag- true, if mouse button is pushed down, false if pushed up.
Returns
true if this shape should get focus to catch all mouse movements.

Reimplemented from iview::CRectControlledShapeBase.

Reimplemented in iview::CTubePolylineShape, and iview::CPolylineShape.

virtual bool iview::CPolygonShape::OnMouseMove ( istd::CIndex2d  position)
virtual

It is called, when mouse is moved.

Only objects with focus receive this event.

Parameters
position- position of mouse pointer on client area (picture coords).
Returns
true if this shape should hold focus to catch longer all mouse movements.

Reimplemented from iview::CInteractiveShapeBase.

Reimplemented in iview::CTubePolylineShape.

void iview::CPolygonShape::SetAlwaysMovable ( bool  state = true)
inlinevirtual

Set flag if in all edit modes is this shape draggable.
