MDG ShapeScript render class as a use case

[Guillaume]

Hello,

I have a stereotyped class that I need to display as a Use Case (ellipse) based on a tagged value.
I can't get the element name to be printed in the middle.

I ran a test without the Tagged value condition which works:

Code: [Select]

shape main{
h_align = "center";
v_align = "center";
ellipse (0, 0, 100, 100);
print("#name#");
}

With the following ShapeScript, I'm getting the following error: Unexpected symbol h_align

Code: [Select]

shape main{
      if (HasTag('UC','true'))
{
h_align = "center";
v_align = "center";
ellipse (0, 0, 100, 100);
print("#name#");
}
else
{
DrawNativeShape();
}
}

I also tried the following but the label is still rendered in the top left corner.

Code: [Select]

shape main{
      if (HasTag('UC','true'))
{
ellipse (0, 0, 100, 100);
addsubshape("uclabel");
shape uclabel{
setorigin("CENTER",0,0);
print("#name#");
}
}
else
{
DrawNativeShape();
}
}

Hi Guillaume,

Try using shape Label  as in:

Code: [Select]

shape Label   //v2.2 29-Nov-2021   //@CENTER
{
   if(hasproperty("rectanglenotation","0"))   //label only in Icon Form
   {
      setorigin("CENTER",0,0);
      print ("#Name#");
    }
}      //Shape: Label   //@CENTER   
[code]


HTH,

   h_align = "center";
   v_align = "center";

are only valid at the beginning of a (sub)shape

If you are happy with your main shape, you should be able to put that into a subshape, and add the subshape conditionally.
So something like (without testing)

Code: [Select]

shape main{
      if (HasTag('UC','true'))
{
addSubShape("useCase", 100, 100);
}
else
{
DrawNativeShape();
}
shape useCase
{
h_align = "center";
v_align = "center";
ellipse (0, 0, 100, 100);
print("#name#");
}
}

Hi Geert and Paolo,
