I want to get mouse event information (Mouse down/Up). [message #1767358]

Hello.

I attach an image for explaining my situation.

index.php/fa/29850/0/

Left side is a sample instance diagram and right one is its metamodel.

When a user has created two problems (in this case, A and B) and want to connect the two elements from B to A using a contribution element (this case, C), I want to get the source (i.e., B) and the target (i.e., A) information from mouse down and up events.
Is there any way to do it?

Thank you so much in advance.

Best regards,
Grace

Hi,

It seems you need an Element-Based Edge [1] to represent the contribution elements and a edge creation tool [2].

For the edge mapping, with domain class Contribution, after setting the source and target mappings to your "Problem" mapping, you can use feature:contribType as source finder expression and feature:target as target finder expression. Do not forget to define the semantic candidate expression with an expression to retrieve the Contributions elements from the diagram semantic target.

Then you can define an edge creation tool referencing your mapping, in the tool operation you wll have to create the Contribution element and to set the contribType and target.

Regards,

Maxime

Hi again,

From the title of your post "I want to get mouse event information (Mouse down/Up)", it seems that my previous answer might not be adapted.

In Sirius, you have the possibility to define the double click behavior with the corresponding tool, but if your need to get mouse event you will have to look into GEF capabilities and maybe provide your own drag tracker, edit policies, etc
