Hello everyone

I have a little issue to get a image in the background of a node.

I tried some workaround like this <--- oh cant show because i have less then 5 messeges^^<--- let me say in this forum

but i can't show the image in my figure.

I want to build up an editor with a image file that shows a trainmap and i want to set some circles on the stations and save their x and y attribute in dependency to the picture.

I hope someone can help me with this problem

Sascha

Hi Sascha,

what exactly is your Problem with the the image? Can you show some code or a Stacktrace if an exception is thrown?

To display an image you can use an ImageFigure and return it in the createFigure method of your EditPart.

Regards,
Andreas

Hi, Someone know anyway to change the figure when we take a double click on the figure?

Hello!

The shortest way should be to introduce dedicated property of the semantic element,
and make figure dependent on the property (this was discussed on the forum and on the GMF wiki).
Than, a custom EditPolicy capable of handling GroupRequest of the REQ_OPEN type should be registered,
the EditPolicy should return ICommandProxy(SetValueCommand), which will change the semantic property.
