Hi there,
i am writing a plugin which displays three views.
The Eclipse Views should all be connected to the same model and show
different "views" onto that model (for example a Graph and Tree View of
that model).
IŽve implemented such a thing before in pure Java Swing but donŽt know how
to get this working within Views (extended from Viewpart) within an
Eclipse plugin. I donŽt know how to connect Viewpart-Views onto a model.
Could you give me a short description on how to do this?
Or point me towards some infos?
IŽve looked for ages but have found nothing.
Greetings
Andreas

Yup, this is a great article. The thing that is probably needed here is that the selection listener needs to be wired up, so that if the selection changes, the view updates appropriately:
... getViewSite().getPage().addSelectionListener(this);
...
public void selectionChanged(IWorkbenchPart part, ISelection selection) {
if (selection instanceof IStructuredSelection) {
Object first = ((IStructuredSelection)selection).getFirstElement();
if (first instanceof Word) {
label.setText(((Word)first).toString());
}
}
}
However, that will only help if the model is essentially static, and that you want to update views when you change the selection. If your model is dynamic, and updating data, then you probably have to use some kind of PropertyChangeEvent, as well as registering/deregistering when the selection changes.

Hi,
Thanks to you three for your answers.
IŽve looked through everything you told me and also had a look at the
SWT/JFace components and experimented with a View holding a JFace Table.
Actually i have a problem, which class(es) i need additonally to connect
all of the ContentProviders to my inital-base-model and where i should
instantiate all of the ContentProviders and JFace widgets....
Should i instantiate them in the views they are embedded in?
Or should i instantiate them in a "base class" and then try to get the
widgets for the view from this base class?
When i instantiate them in the views, i canŽt connect them to my
base-model, as i need instances of the ContentModels to do so.
When i instantiate them in a "base class", how can i get them (and their
widgets) into the Views?
Do you understand what i mean?
I havenŽt found anything on how to do this.
Would be great if someone could help one more time. I really donŽt know
how to manage this.
Andreas
