◆ OnModelAttached()

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

overridevirtual

Callback invoked when an observable model is about to be attached to this observer.

This method is called by the model when attempting to establish an observer relationship. The implementation should:

Validate that the model is of an acceptable type
Set the changeMask to specify which changes to monitor
Return true to accept the attachment, or false to reject it

Parameters

modelPtr	Pointer to the model object being attached. Never nullptr.
changeMask	Output parameter where the observer specifies which change types it wants to be notified about. Set the appropriate change flags using changeMask.Set(changeId). An empty mask means the observer wants all changes.

Returns: true if the model is accepted and attachment succeeds, false to reject the attachment (e.g., if the model is of incompatible type).

Note: After successful attachment, the observer should initialize its state based on the current model data.; The changeMask allows filtering notifications for better performance. Only changes matching the mask will trigger AfterUpdate() calls.

virtual bool OnModelAttached(IModel* modelPtr, 
                            istd::IChangeable::ChangeSet& changeMask)
{
       // Type check
       CMyModel* model = dynamic_cast<CMyModel*>(modelPtr);
       if (!model) return false;
       
       // Set up change filtering
       changeMask.Set(CMyModel::CF_DATA_CHANGED);
       changeMask.Set(CMyModel::CF_STATUS_CHANGED);
       // Don't set CF_INTERNAL_CHANGED - we don't care about those
       
       // Initialize view from current model state
       UpdateViewFromModel(model);
       return true;
}

Reimplemented from iview::CShapeBase.

Reimplemented in iview::CAffineTransformation2dShape, iview::CAnnulusSegmentShape, iview::CAnnulusShape, iview::CArcShape, iview::CCircleShape, iview::CGraphPlotShape, iview::CLabelShape, iview::CLineShape, iview::COrientedCircleShape, iview::CParallelogramShape, iview::CPinShape, iview::CPolygonShape, iview::CPolylineShape, iview::CRectangleShape, and iview::CSplineShape.

◆ OnModelDetached()

virtual bool iview::CInteractiveShapeBase::OnModelDetached ( imod::IModel * modelPtr )

overridevirtual

Callback invoked when an observable model is about to be detached from this observer.

This method is called when the observer-model relationship is being terminated, either explicitly or because the model is being destroyed. The implementation should clean up any state or resources related to this model.

Parameters

modelPtr Pointer to the model object being detached

Returns: true if the detachment was handled successfully, false otherwise

Note: After this call, the observer should not access the model pointer anymore.; This method may be called even if OnModelAttached() previously returned false.; Clean up any cached data or references to this model.

virtual bool OnModelDetached(IModel* modelPtr)
{
       if (m_currentModel == modelPtr) {
              // Clear any cached data
              m_cachedData.clear();
              m_currentModel = nullptr;
              
              // Update UI to show no model is attached
              ClearDisplay();
              return true;
       }
       return false;
}

◆ OnMouseButton()

virtual bool iview::CInteractiveShapeBase::OnMouseButton	(	istd::CIndex2d	position,

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).

◆ OnMouseMove()

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

overridevirtual

It is called, when mouse is moved.

Returns: true if this shape should hold focus to catch longer all mouse movements.

Implements iview::IMouseActionObserver.

Reimplemented in iview::CAnnulusSegmentShape, iview::CAnnulusShape, iview::CArcShape, iview::CCenterPinShape, iview::CCircleShape, iview::CLabelShape, iview::CLineShape, iview::CParallelogramShape, iview::CPinShape, iview::CPolygonShape, iview::CRectangleShape, and iview::CTubePolylineShape.
