Q&A - Question

Hello Dev Team,

i have a problem with the newiest DK11 in painting a Shape Polygon.

i use this code which works in DK10 without any problems but in DK11 the ControlLegend.GisLayer is still nil.
 

      LayerPolygon.Build(layerpfad, GIS.Extent, gisShapeTypePolygon);
      LayerPolygon.name := layername;
      LayerPolygon.path := layerpfad;
      LayerPolygon.Caption := Beschriftung;

      // speichere einmalig das shp auf die Festplatte
      LayerPolygon.SaveAll;

      if FileExists(LayerPolygon.path) then
      begin
        // Weise editierLayer den neu erzeugten Layer zu
        editLayer := TGIS_LayerVector.Create;
        editLayer.path := LayerPolygon.path;
        TGIS_LayerSHP(editLayer).Params.Area.Color := TGIS_Color.blue;
        TGIS_LayerSHP(editLayer).Params.Area.OutlineWidth := 25;
//        editLayer.Params.
        editLayer.Transparency := 60;
        editLayer.SaveAll;

        // Lege Gruppen an, wenn nicht vorhanden
        if not Assigned(GIS.Hierarchy.Groups['Zeichnungen']) then
        begin
          group := GIS.Hierarchy.CreateGroup('Zeichnungen');
        end
        else
        begin
          group := GIS.Hierarchy.Groups['Zeichnungen'];
        end;

        GIS.add(editLayer);
        group.addlayer(editLayer);

        GIS_ControlLegend1.Update;


        GIS_ControlLegend1.GIS_Layer := TGIS_Layer(editLayer);

        shpPolygon := TGIS_ShapePolygon(TGIS_LayerVector(editLayer).CreateShape(gisShapeTypePolygon));
        if shpPolygon <> nil then
        begin
          shpPolygon.Lock(gisLockExtent);
          shpPolygon.AddPart;
        end;

        GIS.Editor.EditorMode := TGIS_EditorModeEx.Normal;
        GIS.mode := gisEdit;
        GIS.Update;

can someone explain me why?
