Modifying the BitmapView Class to Catch the New Actions

The Bitmap Editor Application > Step 5: Adding Zoom Commands > Modifying the BitmapView Class to Catch the New Actions

First, the interface of the view must be modified to declare the new actions:

IlvDvBeginInterface(BitmapView)

Method1(BitmapHasChanged, bitmapHasChanged, IlAny, region)

Action(ZoomIn, zoomIn)

Action(ZoomOut, zoomOut)

IlvDvEndInterface1(IlvDvFormView)

Then, the BitmapView::zoomIn and BitmapView::zoomOut methods need to be implemented.
