Building umlet custom elements

Question

I am trying to do a collaboration diagram in umlet, but there isn't a palette element to do so. So I thought I'd create one. Easier said than done! I am able to define the class element of the diagram, but am unable to define the arrows that define the flow of the collaboration.

I've tried adding a drawline statement to the code window, but it is undefined in umlet custom element implementation.

    //Modify the code below to define the element's behavior.
    //
    //Example:  Change the line
    //  y += printCenter(textline,y);
    //to
    //  y += 2*printCenter(textline,y);
    //and observe the element preview.

    int y=textHeight();

    drawRectangle(0,0,100,35);
    drawRectangle(0,150,100,35);
    //drawline(10,35,10,115);


    for(String textline : textlines) {
        y += printCenter(textline,y);
    }

The expected result should be two class elements and two arrows denoting the flow of the collaboration.

I've gotten this far, but I am unable to save it to the custom elements palette.

Welllll, my bad! It turns out that you can use the regular palette elements to construct the diagram and then save it to umlet's palettes directory.
