The Blinking Renderer

The Blinking renderer allows you to obtain color or visibility blinking on graphic objects. It must be enabled to get the blinking effect in a diagram view.

The blinking can be defined in CSS in two different ways:

Toggling between two colors

A CSS function defines two blinking colors that can be used for a property of type Color. The following example shows a general node, with its main shape changing colors between red and black.

node.particular {
    class : "ilog.views.sdm.graphic.IlvGeneralNode" ;
    label : "@name" ;
    fillColor1 : "@|blinkingColor(red,black)" ; // toggles from red to 
black
}

Code Sample 4.10 Color Blinking

Toggling the visibility

The renderer property ToggleVisibility switches the visibility of the whole object. The following example toggles the visibility of some nodes:

node.particular {
    class : "ilog.views.sdm.graphic.IlvGeneralNode" ;
    label : "@name" ;
    ToggleVisibility :  "true";
}

Code Sample 4.11 Visibility Blinking

Table 4.3 lists the global properties of the Blinking renderer

Table 4.3 Global Properties of the Blinking Renderer

Property	Type	Default	Description
onPeriod	int	1000	The duration, in milliseconds, of the first color specified in the `blinkingColor` function, or of the visible period when `ToggleVisibility` is set to `true`.
offPeriod	int	1000	The duration, in milliseconds, of the second color specified in the `blinkingColor` function, or of the invisible period when `ToggleVisibility` is set to `true`.

Table 4.4 lists the per-object properties of the Blinking renderer

Table 4.4 Per-Object Properties of the Blinking Renderer

Property	Type	Default	Description
ToggleVisibility	boolean	false	If the value of this property is `true`, the graphic representation will toggle the visibility.

The blinkingColor CSS function takes two arguments of type Color. These arguments can be specified as a color name, or as a raw RGB/RGBA string (like #30FA6B, or #30FA6B80, where the last byte, 80, represents the alpha level (= transparency)). The function returns an ilog.views.sdm.renderer.IlvBlinkingColor, which subclasses java.awt.Color.

See the class ilog.views.sdm.renderer.IlvBlinkingRenderer for more details.
