Hi,
I am new here. I started using papyrus rt and the development environment for papyrus RT in eclipse mars. So when I run papyrus rt development environment , it creates an instance where I can view papyrus rt model. But now I want to change the model (states) color or shape in the instance level programmatically. Right now I am trying to write a plug in which will have a button, and in the instance when user will click the button it should change the color of the model. I know the exact name of the state (i,e capsule name _ state name). So using this name I want to change the color in the model. Till now I couldn't find any appropriate way to do this. I'll be grateful if anyone can help me in this regard. Thanks!

Hi,
There are basically two options for modifying the appearance of nodes in Papyrus (Not specific to Papyrus-RT):
1) Change the Notation model directly
2) Use a CSS Stylesheet and apply it to your project, model or diagram
For the first option, you need to:
- Find the Notation View associated to your UML Element. Usually, it is the first view (Shape, or Connector...) with a reference to your element (e.g. <Shape element="model.uml#yourElementID" ... />)
- Use the View#setFillColor(int) method to change the color
The pseudo-code looks like:
State myState = ...;
Shape stateRepresenation = findView(myState);
stateRepresentation.setFillColor(123456); //The color is a 24-bits integer representing the RGB code
Note that you need to start a transaction before being able to modify a Papyrus model; otherwise the change will be rejected. This can be achieved by executing a Command on the model's CommandStack
For the second option, you need to:
- Create a *.css text file which will contain the rules to change the colors
- Generate some rules matching the following pattern inside this *.css file:
State[name="MyState"]{
fillColor: red;
}
State[name="MyOtherState"]{
fillColor: rgb(125, 255, 32);
}
Then apply this stylesheet to your project, model or diagram
Please feel free to ask if you need additional information for these steps
HTH,
Camille
