Giving Edge Color to Edge Target Arrow

[pritam saha]

Hello Everyone, 

I am trying to apply RGB color the edge target arrow which is of delta shape. 

I have used this below code to apply the Delta shape for edge target arrow. 

VisualStyle vs = cyServiceRegistrar.getService(VisualStyleFactory.class).createVisualStyle(currentStyle);

vs.setDefaultValue(BasicVisualLexicon.EDGE_TARGET_ARROW_SHAPE, ArrowShapeVisualProperty.DELTA);

But I am not able to give color to the tip of the edge. 

There is some property which we can do from a xml file. Below is the sample example

<visualProperty name="EDGE_TARGET_ARROW_UNSELECTED_PAINT" default="#000000"/>

<visualProperty name="EDGE_TARGET_ARROW_SELECTED_PAINT" default="#ffff00"/>

I need to do this using programmatically.  

Please help me with this issue. 

Thanks,

Pritam

First guess:  Did you apply the style?

Hi Alex,

Thank you for your response. 

Actually, I was not able to find the class for the property Edge Target Arrow like BasicVisualLexicon.EDGE_UNSELECTED_PAINT under   BasicVisualLexicon. 

It was not defined there. 

So, I have tried to find some solutions in the GitHub repositories and then I have seen some of the properties are used from the rendering manager. 

I have used the below code.

VisualLexicon lex = cyServiceRegistrar.getService(RenderingEngineManager.class).getDefaultVisualLexicon(); 

VisualProperty targetedgecolor = lex.lookup(CyEdge.class,"EDGE_TARGET_ARROW_UNSELECTED_PAINT"); 

vs.setDefaultValue(targetedgecolor,Greencolor);

And It worked. 

Thanks,

Pritam

Hi Pritam,

  Exactly right!  Not all properties are available through the BasicVisualLexicon.  In particular, the EDGE_TARGET and EDGE_SOURCE paints are only defined in "ding", the default 2D renderer.  That's why you need to actually go through the lookup.
