Class IlvBlinkingRenderer

java.lang.Object

ilog.views.sdm.renderer.IlvSDMRenderer

ilog.views.sdm.renderer.IlvFilterSDMRenderer

ilog.views.sdm.renderer.IlvBlinkingRenderer

public class IlvBlinkingRenderer
extends IlvFilterSDMRenderer

The class IlvBlinkingRenderer is a filtering renderer that makes the grapher objects blinking. It works together the classes IlvBlinkingColor, IlvBlinkingPaint, IlvBlinkingMultiColor, and IlvBlinkingMultiPaint.

This example shows how to toggle the colors of the grapher objects every seconds.

  SDM {
    Blinking : "true";
  }
  Blinking {
    onPeriod : 1000;  // Every second
    offPeriod : 1000;  // Every second
  }
  node {
    class : "ilog.views.sdm.graphic.IlvGeneralNode" ;
    label : "@name" ;
    // toggles from red to black (2 states):
    fillColor1 : "B1000/1000[red/black]" ; 
    // toggles from black to transparent red to yellow (3 states):
    labelColor : "B500[black/#aaff0000/yellow]" ;
  }
  

An alternative way to specify blinking 2-state colors is by using the blinkingColor function:

  node {
    class : "ilog.views.sdm.graphic.IlvGeneralNode" ;
    label : "@name" ;
    // toggles from red to black:
    fillColor1 : "@|blinkingColor(red,black)" ; 
    // toggles from black to fully transparent (that is, invisible): 
    labelColor : "@|blinkingColor(black,#00000000)" ; 
  }
  

This example extract shows how to specify a more complex blinking paint that toggles between two paints every seconds.

  node {
    class : "ilog.views.graphic.IlvGeneralPath";
    fillPaint : "@=fillPaint";
    fillOn : "true";
  }
  Subobject#fillPaint {
    class : "ilog.views.util.java2d.IlvBlinkingPaint(onPaint,offPaint,onPeriod,offPeriod)";
    onPaint : "@#onPaint";
    offPaint : "@#offPaint";
    onPeriod : "1000";
    offPeriod : "1000";
  }
  Subobject#onPaint {
    class : "java.awt.GradientPaint(point1,color1,point2,color2)";
    point1 : "0.0,0.0";
    color1 : "white";
    point2 : "72.0,72.0";
    color2 : "255,0,51";
  }
  Subobject#offPaint {
    class : "java.awt.GradientPaint(point1,color1,point2,color2)";
    point1 : "0.0,0.0";
    color1 : "255,0,51";
    point2 : "72.0,72.0";
    color2 : "white";
  }
  

Besides blinking colors and paints, the rendering property ToggleVisibility switches the visibility of the objects. For instance:

  SDM {
    Blinking: "true";
  }
  Blinking {
    onPeriod: 1000;  // Every second
    offPeriod: 1000;  // Every second
  }
  node {
    ToggleVisibility : "true";
    class : "ilog.views.sdm.graphic.IlvGeneralNode";
    label : @Name;
  }
  

CSS example:

ilvBlinkingRenderer {
class : "ilog.views.sdm.renderer.IlvBlinkingRenderer";
alias : "<value>";
enabled : "false";
offPeriod : "2";
onPeriod : "2";
parameter : "<value>";
}

java.lang.String	alias Sets the alias of this renderer.
java.lang.String	class Default constructor.
boolean	enabled Sets whether blinking is enabled.
int	offPeriod Sets the off period.
int	onPeriod Sets the on period CSS example: onPeriod : "2";
java.lang.String	parameter This method gives access to a privileged parameter of the renderer, and allows this parameter to be specified quickly in the main option rule of the style sheet.

Property Detail

class

public java.lang.String class

Default constructor.

CSS example: class : "ilog.views.sdm.renderer.IlvBlinkingRenderer";

alias

public java.lang.String alias

Sets the alias of this renderer. The alias is the symbolic name used to designate the renderer in the SDM style sheet, for example SubGraph or GraphLayout.

CSS example: alias : "<value>";

enabled

public boolean enabled

Sets whether blinking is enabled.

CSS example: enabled : "false";

offPeriod

public int offPeriod

Sets the off period.

CSS example: offPeriod : "2";

onPeriod

public int onPeriod

Sets the on period

CSS example: onPeriod : "2";

parameter

public java.lang.String parameter

This method gives access to a privileged parameter of the renderer, and allows this parameter to be specified quickly in the main option rule of the style sheet.

For example, the main parameter of the ilog.views.sdm.renderer.maps.IlvMapRenderer is the name of the map file. You can specify that you want to display a map of the USA by the single declaration:

    SDM {
      Map : "usa.ivl";
    }
  

The default implementation does nothing. Subclasses should override this method to give access to their main parameter.

CSS example: parameter : "<value>";
