Show Hidden Objects
Windows only
Demonstrates how to iterate through the geometry table and unhide hidden objects.
int ShowAllHiddenObjects( CRhinoDoc& doc, bool bRedraw ) { CRhinoObjectIterator it( doc, CRhinoObjectIterator::undeleted_objects, CRhinoObjectIterator::active_and_reference_objects ); it.IncludeLights(); int count = 0; CRhinoObject* obj = 0; for( obj = it.First(); obj; obj = it.Next() ) { // Ignore objects that are not hidden if( obj->Attributes().Mode() != ON::hidden_object ) continue; // Ignore objects on hidden or locked layers if( ON::normal_layer != obj->ObjectLayer().Mode() ) continue; if( doc.ShowObject(obj) ) count++; } if( count > 0 && bRedraw ) doc.Redraw(); return count; }
