Node with more than one label [message #1787071]

Hi,

from the Tutorial it is know, that you can edit an Feature (like name) of an element (like man) via the Label Edit Tool.

Therefor it could be beneficial to me, if I had a Node with multiple labels, that I can edit independently.

For Example:
The label of the ManNode shows the name. I can edit the label, and the name of the man changes. If you had a second label that shows the age of the man, I could change 2 features of one element, without the propertyView, what so ever.

index.php/fa/32851/0/

Is that possible? Or is there an equal way already?

Hello,

I think you have several way to do it:
- With a label edit tool, you can edit several properties at once depending how you defined the masks (by default there is only {0} to edit one field);
- You can define a double click tool containing an "Open Dialog" operation where you can edit each field you define in one view;
- Provide a custom style [1] with an EditPart having several LabelEditPart....but I think it is far more complicated and overkill for this.

Regards,
Steve

Hi Steve,
thanks a lot for your answer.
I have not defined a mask before, so I would like to ask one or two things about it.

When the Label says "Peter, 25" the value of {0} is by Default "Peter, 25".
So is it possible to define a Var {1}, which value will be everything before the comma: "Peter"
and a Var {2}, wgich will be everything after the comma: "25"?

So I can declare my "Set" Operation like this:

Feature Name: name
Valuze Expression:var:1
______________________

Feature Name: age
Value Expression:var:2

Is there a tutorial?

Thanks a lot for your help!!!

Hello Andreas,

If you display your labels as the example "Peter,25" then in your direct edit tool, you need to edit the Mask Variables from '{0}' to '{0},{1}'. This way the ',' identifies where we split between two arguments. Then in your tool, you can have a first "Set" operation where the feature ame field will be name and the value expression field will be var:arg0 (as usual then). Finally, you will add a second "Set" operation with a feature name as "age" and a value expression as "var:arg1".

I don't think that we have a tutorial about it, but as you can see it is pretty easy to use.

Regards,
Steve
