In Draw and Impress, each shape is associated to exactly one layer. The layer has properties that specify if connected shapes are visible, printable or editable.
The service com.sun.star.drawing.DrawingDocument implements the interface com.sun.star.drawing.XLayerSupplier that gives access to the com.sun.star.drawing.XLayerManager interface. The com.sun.star.drawing.XLayerManager interface is used to create and edit a layer, and is used to attach a layer to a shape.
XShapes xShapes = (XShapes)UnoRuntime.queryInterface(XShapes.class, xPage); XShape xRect1 = ShapeHelper.createShape(xComponent, new Point(1000, 1000), new Size(5000, 5000), "com.sun.star.drawing.RectangleShape"); XShape xRect2 = ShapeHelper.createShape(xComponent, new Point(1000, 7000), new Size(5000, 5000), "com.sun.star.drawing.RectangleShape" ); xShapes.add(xRect1); xShapes.add(xRect2); XPropertySet xTextProp = ShapeHelper.addPortion(xRect2, "this shape is locked", false); xTextProp.setPropertyValue("ParaAdjust", ParagraphAdjust.CENTER); ShapeHelper.addPortion(xRect2, "and the shape above is not visible", true); ShapeHelper.addPortion(xRect2, "(switch to the layer view to gain access)", true); // query for the XLayerManager XLayerSupplier xLayerSupplier = (XLayerSupplier)UnoRuntime.queryInterface( XLayerSupplier.class, xComponent); XNameAccess xNameAccess = xLayerSupplier.getLayerManager(); XLayerManager xLayerManager = (XLayerManager)UnoRuntime.queryInterface( XLayerManager.class, xNameAccess); // create a layer and set its properties XPropertySet xLayerPropSet; XLayer xNotVisibleAndEditable = xLayerManager.insertNewByIndex(xLayerManager.getCount()); xLayerPropSet = (XPropertySet)UnoRuntime.queryInterface( XPropertySet.class, xNotVisibleAndEditable); xLayerPropSet.setPropertyValue("Name", "NotVisibleAndEditable"); xLayerPropSet.setPropertyValue("IsVisible", new Boolean(false)); xLayerPropSet.setPropertyValue("IsLocked", new Boolean(true)); // create a second layer XLayer xNotEditable = xLayerManager.insertNewByIndex(xLayerManager.getCount()); xLayerPropSet = (XPropertySet)UnoRuntime.queryInterface(XPropertySet.class, xNotEditable); xLayerPropSet.setPropertyValue("Name", "NotEditable" ); xLayerPropSet.setPropertyValue("IsVisible", new Boolean(true)); xLayerPropSet.setPropertyValue("IsLocked", new Boolean(true)); // attach the layer to the rectangles xLayerManager.attachShapeToLayer(xRect1, xNotVisibleAndEditable); xLayerManager.attachShapeToLayer(xRect2, xNotEditable);
