All Implemented Interfaces:

Serializable

public class IlvDecorationRenderer
extends IlvFilterSDMRenderer

The class IlvDecorationRenderer is a filtering renderer that adds various IlvGraphics in the manager.

The added objects are defined through a given style sheet (or through the style sheet of the IlvSDMEngine). To add graphic object, simply define names in this renderer (see setDecorationNames()) and it will try to load and add IlvGraphics corresponding to the names. The following example creates two filled rectangles and place them in the shape of an L with the corner at (0,0):

 SDM {
        Decoration : true;
 }
 
 Decoration {
        decorationNames : 'testV,testH';
 }
 
 // decorations
 
 #testH  {
    class       : 'ilog.views.interactor.IlvMakeFilledRectangleInteractor';
        IlvRect     : '10,20,100,2';
        x           : 0;
        y           : 0;
        layer       : 3;
        anchor      : TopLeft;
        foreground  : pink;
 }
 
 #testV  {
    class       : 'ilog.views.interactor.IlvMakeFilledRectangleInteractor';
        IlvRect     : '10,50,2,100';
        x           : 0;
        y           : 0;
        anchor      : BottomRight;
        layer       : 3;
 }
 

The renderer also has three properties used to fix the background color, the background pattern of the view, and to load an arbitrary .ivl file.

Since Rogue Wave JViews version 8.0, this class can also load SVG and DXF files.

Since:

JViews 4.0

Constructor Detail

IlvDecorationRenderer

public IlvDecorationRenderer(IlvSDMRenderer renderer)

Creates a new decoration renderer for a specified filtered renderer.

Parameters:

renderer - The filtered renderer.

IlvDecorationRenderer

public IlvDecorationRenderer()

Creates a new decoration renderer with a null filtered renderer.

Method Detail

setDecorationNames

public void setDecorationNames(String[] names)

Sets the names of the decoration objects. These names are matched with the ID in the CSS.

Parameters:

names - The names of the decoration objects.

getDecorationNames

public String[] getDecorationNames()

Gets the names of the decoration objects.

setDecorationContext

public void setDecorationContext(String context)

Sets the decoration context (that is, an additional CSS class to match for all the decoration rules). It is then possible to trigger some of the decorations according to the context by adding the class to the rule selector.

Parameters:

context - The decoration context.

getDecorationContext

public String getDecorationContext()

Gets the decoration context.

setBackgroundFile

public void setBackgroundFile(URL ivlFile)
                       throws IOException,
                              IlvReadFileException

Sets a URL that points to a Rogue Wave JViews formatted file (.ivl). The file contains Rogue Wave JViews graphic objects that are added in the engine grapher only when IlvSDMEngine.loadData() is invoked.

Since Rogue Wave JViews version 8.0, this class can also load SVG and DXF files.

Parameters:

ivlFile - The new background .ivl URL.

Throws:

IOException - An IO error occurs.

IlvReadFileException - This exception occurs when the grapher cannot read the file either because the file is not a Rogue Wave JViews file, or because the format is not correct or some graphic classes cannot be found.

Since:

JViews 5.0

See Also:

IlvManager.read(java.net.URL)

getBackgroundFile

public URL getBackgroundFile()

Gets the background file.

Since:

JViews 5.0

isFitToContent

public boolean isFitToContent()

Returns the value of the "fit-to-content" flag.

Since:

JViews 6.5

See Also:

setFitToContent(boolean)

setFitToContent

public void setFitToContent(boolean fitToContent)

Specifies whether a "fit-to-content" will be performed after the background file has been loaded. This flag is effective only when a background file has been specified using setBackgroundFile(URL).

The default value is true.

Parameters:

fitToContent - If true, a "fit-to-content" will be performed after the background file has been loaded, otherwise the view's transformer will be left unchanged.

Since:

JViews 6.5

See Also:

isFitToContent()

setBackground
