I'm a total beginner to this framework, and I'm quite lost.

I need to put a line into the canvas of the editor, but I don't know how

Thanks

Hi,

Do you want the line in the diagram to represent an element in the
model? e.g.

<root>
<object a>
<object b>
<connection from:a to:b>
</root>

If you would like the 'connection' object to be represented as a line
between a and b, you will need to specify it's visual notation in your
..gmfgraph, the creation tool in the .gmftool, the mapping in the
..gmfmap, and then combine them all together into the .gmfgen to generate
your diagram editor. The GMF tutorials go into this quite well.

Thanks Jevon

The line is not a connection between two items, it should represent a
single attribute (it's a timeline) of an object of the model.

So, i have an object with a time attribute, represented with this line,
and this line should be able to move along the canvas
