Hi all,

I should start a view for an Eclipse RCP where user could drag an image chosen from (suppose) a palette and drop on a central area of the view.

Do you know some reference tutorial, article, snippet which do a similar thing?

Have you some hint or guide lines to work with similar concepts?

Thanks in advance and best regards
Raffaele

There are many ways to do it using a canvas...

What is your requirement???
Is it a photo viewer kind of thing or
a model editor kind of thing(like UML editor) ?

if it is model editor king of thing go for GEF/GMF...

My requirement is a kind of magnetic board where user should put and remove some item and should draw some arrows lines between items.

There should be also a contextual menu over these items.

Standing at what you are saying should I investigate better GEF/GMF? If yes, I ask same question, do you know some starting point reference?

Is only my opinion or aren't there so much tutorials on the web about these kind of interfaces?

Thanks again and best regards
Raffaele

Your requirement exactly fits into GEF/GMF..

the starting point would be below url
http://www.eclipse.org/gef/

There is a gef shapes example from where you can start..

GMF is an advanced framwork,i would recomend not to venture..
but still the link is
http://www.eclipse.org/modeling/gmf/
