[Eugenia] Color and Size of a Custom Figure [message #769601]

Hello,

new in Eugenia and the whole GMF stuff i am trying to build a graphical editor.

In my model i am using a custom figure as u can see in the following code snippet:

@gmf.node(label="name", tool.name="MergeData", color="255,100,0",
figure="org.eclipse.epsilon.eugenia.examples.flowchart.diagram.figures.DiamondFigure")
class MergeDiamond {
  @gmf.affixed(foo="bar")
  ref InPort[1..3] inPort;
  @gmf.affixed(foo="bar")
  ref OutPort[1] outPort;
}

In the corresponding ECore2GMF.eol i am trying to fix its size:

var mergeDiamond = GmfGraph!CustomFigure.all.selectOne(r|r.name = "MergeDiamondFigure");
if (mergeDiamond.isDefined()) {
	var label = mergeDiamond.children.selectOne(r|r.name = "MergeDiamondLabelFigure");
	label.text = "";
	var fixSize = new GmfGraph!Dimension;
	fixSize.dx = 41;
	fixSize.dy = 41;
	mergeDiamond.maximumSize = fixSize;
	var fixSize2 = new GmfGraph!Dimension;
	fixSize2.dx = 40;
	fixSize2.dy = 40;
	mergeDiamond.minimumSize = fixSize2;
}

Here is the code of the generated .gmfgraph:

 <descriptors
        name="MergeDiamondFigure">
      <actualFigure
          xsi:type="gmfgraph:CustomFigure"
          name="MergeDiamondFigure"
          qualifiedClassName="org.eclipse.epsilon.eugenia.examples.flowchart.diagram.figures.DiamondFigure">
        <backgroundColor
            xsi:type="gmfgraph:RGBColor"
            red="255"
            green="100"/>
        <maximumSize
            dx="41"
            dy="41"/>
        <minimumSize
            dx="40"
            dy="40"/>
        <children
            xsi:type="gmfgraph:Label"
            name="MergeDiamondLabelFigure"
            text=""/>
      </actualFigure>
      <accessors
          accessor="getFigureMergeDiamondLabelFigure"
          figure="//@figures.0/@descriptors.11/@actualFigure/@children.0"/>
    </descriptors>

But what i thought i would see is not what i did get Sad

1. The custom figure stays white
2. I still can resize it greater than specified maxsize

A similar question for 2. (Is it possible to avoid resizing a figure during its creation and after it?) was asked in another thread, but following the link there i still didn't get an answer to this question and the other two asked there.
I can't post the link cause its my first posting here. So here is the topic and message-id of the thread: Problem with nodes affixed to an ellipse [message #658658]

So, my questions are:

1. Why am i not able to colorize the custom figure?
2. Why is it possible to resize it bigger then given maxsize?
3. Do i have to alter the generated code for creating the affixed Ports in the same Moment the Diamondfigure was created as in aforementioned thread described?

Thanks in advance.

Hi Wolly,

I'm afraid that all 3 questions are strictly related to GMF (Eugenia goes as far as generating the .gmfxxx models from the annotated .ecore and then passes them on to the GMF generator) so I suspect that experts in the GMF forum will be better positioned to help with these.

Cheers,
Dimitris

Hi Dimitris,

thanks for the info. I will then open a new topic there.
