◆ CalcBoundingBox()

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

overrideprotectedvirtual

Calculate bounding box.

You have to implement this method in your shapes implementations.

Reimplemented from iview::CPolylineShape.

◆ DrawCurve()

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

overrideprotectedvirtual

Reimplemented from iview::CPolylineShape.

◆ DrawPolyBezier()

		const i2d::CVector2d *	pointsPtr,
		int	pointsCount

◆ GetSegmentMiddle()

◆ IsCurveTouched()

overrideprotectedvirtual

Reimplemented from iview::CPolylineShape.

◆ OnModelAttached()

virtual bool iview::CSplineShape::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;
}
