am I right, that Riena Ridgets only work 'around' SWT widgets -
not with JFace viewers ?

thx for info

yes thats right.....Ridgets are wrapping or adapting SWT widgets. For some widgets they offer simular functionality like
JFace viewers. We dont accomplish that by reinventing the wheel but by using JFace viewers internally.

So for example the TreeRidget uses internally the TreeViewer. So in your view you only defines the Tree (widget) and
then in your controller you use the TreeRidget to bind your model and stuff like that. There is (of course) a testcase
"TreeRidgetTest" that shows you how that works.

Ridgets are nice here because its a uniform layer for all widgets and of course they offer additional functionality that
is not found in widgets or viewers (like markersupport).

ok - I understand - this makes sense

ok - so I'll only use SWT widgets in my Views designed by SWTdesigner

I've seen this - and also noticed that the RCPMail sample uses the
SWTWidget Tree instead of the TreeViewer.
but I only wanted to be sure, that I understand it right - thats the
reason for my question

these additional cool features are the main reason I want to use it ;-)

but at the moment I have to figure out my design - workflow how I can
use SWTDesigner
and then make the changes for use of Riena - controller and ridgets.

If I don't find a practicable way to do this then I have to go without
Ridgets,
because the use of SWTDesigner is mandatory for my project

btw: do you have also tests for the use of Drag'n'Drop or is this out of
Riena focus
and all works as expected from a normal application ?

thx

Hi Ekke,

drag and drop is not outside the focus of Riena. We havnt just implemented it yet. However it really depends on where
you wonna drag from to where to. I remember about a discussion where you wanted to drag from the navigation tree to the
view. I guess we would need a good description of what kind of drag and drop (the term itself is not enough) and then we
have to see how and when that is implemented. (maybe you like to start a role as code contributor here :-) )

As for the SWT Designer discussion, if that is a pressing issue look at the Riena code snippet that already exists
http://wiki.eclipse.org/Riena_Snippets and then checkout the SWT Designer version that you probably own how that kind of
code can be generated. I think you can modify or enhance the generator to do this.

And then maybe write a little blog how you are doing. I will look at this matter and I will look into this soon, just
not sure how soon "soon" is.

BTW if that controller thing or better the seperation between view and controller is such a big issue, you see in the
Riena code snippets that you can do without it. There you have widgets and ridgets in the same class and method.
