◆ AfterUpdate()

virtual void iview::CImageShape::AfterUpdate	(	imod::IModel *	modelPtr,
		const istd::IChangeable::ChangeSet &	changeSet
	)

overridevirtual

Callback invoked after an update of the observer's content occurs.

This is the primary notification method where observers react to model changes. It's called after the model has finished updating its state. The implementation should examine the changeSet to determine what changed and update accordingly.

Parameters

modelPtr	Pointer to the model that has changed
changeSet	Contains information about what changed in the model. Use changeSet.Contains(changeId) to check for specific changes. The changeSet respects the mask specified in OnModelAttached().

Note: This is typically where you update your GUI, recalculate derived values, or trigger other dependent operations.; Keep this method fast - it's called frequently and may block the UI thread.; Use the changeSet to perform incremental updates rather than refreshing everything.

virtual void AfterUpdate(IModel* modelPtr, 
                        const istd::IChangeable::ChangeSet& changeSet)
{
       CMyModel* model = dynamic_cast<CMyModel*>(modelPtr);
       if (!model) return;
       
       // Selective update based on what changed
       if (changeSet.Contains(CMyModel::CF_NAME_CHANGED)) {
              m_nameLabel->setText(model->GetName());
       }
       if (changeSet.Contains(CMyModel::CF_VALUE_CHANGED)) {
              m_valueSpinBox->setValue(model->GetValue());
              RecalculateDependentValues();
       }
       
       // Re-enable signals if blocked in BeforeUpdate
       if (m_widget) {
              m_widget->blockSignals(false);
       }
}

◆ CalcBoundingBox()

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

overridevirtual

Calculate bounding box.

You have to implement this method in your shapes implementations.

Implements iview::CShapeBase.

◆ Draw()

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

overridevirtual

Draw this shape using draw context.

Implements iview::IVisualizable.

◆ DrawPixmap()

virtual void iview::CImageShape::DrawPixmap	(	QPainter &	painter,
		const QPixmap &	pixmap,
		const i2d::CRect &	bitmapArea,
		const i2d::CAffine2d &	destTransform
	)		const

◆ GetShapeDescriptionAt()

virtual QString iview::CImageShape::GetShapeDescriptionAt ( istd::CIndex2d position ) const

overridevirtual

Get description to shape at specified position.

Reimplemented from iview::CShapeBase.

◆ IsTouched()

virtual TouchState iview::CImageShape::IsTouched ( istd::CIndex2d position ) const

overridevirtual

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.

◆ OnModelAttached()

virtual bool iview::CImageShape::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;
}
