Member Function Documentation

◆ BeginLogDrag()

virtual void iview::CRectangleShape::BeginLogDrag ( const i2d::CVector2d & reference )

protectedvirtual

Implements iview::CInteractiveShapeBase.

◆ CalcBoundingBox()

virtual i2d::CRect iview::CRectangleShape::CalcBoundingBox ( ) const

protectedvirtual

Calculate bounding box.

You have to implement this method in your shapes implementations.

Implements iview::CShapeBase.

◆ CalcPoints()

virtual void iview::CRectangleShape::CalcPoints ( const i2d::CRectangle & rectangle ) const

protectedvirtual

◆ Draw()

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

virtual

Draw this shape using draw context.

Implements iview::IVisualizable.

◆ InvalidateBoundingBox()

virtual void iview::CRectangleShape::InvalidateBoundingBox ( )

virtual

Invalidate bounding box.

You can overload this method to provide validation of your internal attributes, because this method is called from Invalidate and OnDisplayChanged methods. Please don't forget base method call in your implementations.

Reimplemented from iview::CShapeBase.

◆ IsTouched()

virtual TouchState iview::CRectangleShape::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::CRectangleShape::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.

◆ OnMouseButton()

virtual bool iview::CRectangleShape::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).
buttonType	determine the mouse butten type.
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::CInteractiveShapeBase.

◆ OnMouseMove()

virtual bool iview::CRectangleShape::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.

◆ SetLogDragPosition()

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

protectedvirtual

Implements iview::CInteractiveShapeBase.
