node shape: rounded-box not apply

[rmaestre]

Hi everyone, firstly: nice job with this library!!
However, with the next code i have one problem (using 1.1 libraries):

Node n = g.getNode(nodeLabel);
n.addAttribute("ui.style" , ("size: 10px, 10px; fill-color: #3d5689; shape: rounded-box; stroke-mode: plain; stroke-color: yellow;");
n.setAttribute("label",nodeLabel);

With the above code, nodes perform the change of size and fill-color well, but not shape, stroke-mode and stroke-color. In edges does not work shape forms.

Edge e = g.getEdge(from+to);
e.addAttribute("ui.style" , "cubic-curve;");

Any suggestion?
Best regards !

Hi, the viewer included in gs-core supports only a minimal subset of CSS. To have a full CSS support, use the one included in gs-ui. Make sure that gs-ui.jar is in your classpath and use this instruction before displaying the graph:

System.setProperty("gs.ui.renderer",
                "org.graphstream.ui.j2dviewer.J2DGraphRenderer");

Hope this helps.

Works perfectly in the display but ¿This new styles will apply in the pictures save by FileSinkImages?

Graph g = new DefaultGraph("g");
FileSinkImages fsi = new FileSinkImages(...
g.addSink(fsi);
fsi.begin("/tmp/prefix");
// Graph operations
....
fc.close();

Thank you.
Best regards.

With FileSinkImages you should use

fsi.setRenderer(RendererType.SCALA);

Hi there!

I also got a question about the node shape.

I have gs-ui.jar in my classpath and this at the first line of my code:
System.setProperty("gs.ui.renderer", "org.graphstream.ui.j2dviewer.J2DGraphRenderer");

Then I define a node:
Node A = g.addNode("A"); A.setAttribute("ui.label", "Node A");
with the styleSheet like this:
graph {padding:60px; fill-color: red;} node {size-mode: fit; text-style: bold; shape: rounded-box; fill-color: white; stroke-color: yellow; stroke-mode: plain; }
I want to get a reactangle shape of each node. but it only show up as a square.
Except the node shape, the other properties are good.

Any suggestion here? :)

I solved the same issue today. My bug was in gs-ui-javafx org.graphstream.ui.javafx.renderer.shape.javafx.Area
private void sizeForElement(Style style, DefaultCamera2D camera, GraphicElement element) {
...
if(style.getSize().size() > 1)
h = camera.getMetrics().lengthToGu(style.getSize(), 1) ;
...
}

This issue is already fixed graphstream/gs-ui-javafx@bbea8a2 and will be in the next release.

Great, when will be the release ready? ;-)

It depends on a lot of things, but I'm hoping it'll probably be done before the summer.
You can use the dev branch in the meantime
