Hi everybody, I'm a newbie about RCP and I'm trying to do something that
I'm not sure about how can be done. First I've searched about it here but
didn't found anything...
I've got a view where I add widgets in createPartControl in an simple way.
I add a button too which must process the user's input, and then I want to
re-use the same view to load new widgets in it, but I have to remove the
old widgets from it before (I hope you understand my english). That is, I
need to repaint (re-init, reset) the view before I add more widgets.
I suppose it's not a difficult thing to do, but I don't know how to do
it...
Any help would be great!
Thanks in advance!

Take a look at SWT Snippet98

Thanks Wayne, but I'm trying to find a way to re-initialize a view, if that
is possible (I don't know).
Does not exist a way to tell eclipse "dispose every widget in the view and
start drawing again since now"?
Indeed, I'm using a form as container this way:
toolkit = new FormToolkit(parent.getDisplay());
form = toolkit.createScrolledForm(parent);
Then I use form.getBody() as every widget's container, for example:
Button btnExample = toolkit.createButton(form.getBody(), "", SWT.PUSH);
If the user clicks on the button (for example), I would like to reset the
view and start loading other widgets in it. I got the button's listener, but
what must I include there to reset the view?
Maybe if I could "reset" the form, that would be sufficient...
Anyway thanks very much for your help!

Look harder at the snippet.
To clear your view, dispose the widgets you want to get rid of. In the
snippet, they put the widgets on a composite and dispose the composite.
Then create a new composite.
Here's an example:
public class SampleView extends ViewPart {
private Composite contents;
public void createPartControl(final Composite parent) {
contents = new Composite(parent, SWT.NONE);
contents.setLayout(new GridLayout());
new Label(contents, SWT.NONE).setText("Some label");
Button button = new Button(contents, SWT.NONE);
button.setText("Hello");
button.addSelectionListener(new SelectionAdapter() {
public void widgetSelected(SelectionEvent e) {
contents.dispose();
contents = new Composite(parent, SWT.NONE);
contents.setLayout(new GridLayout());
new Label(contents, SWT.NONE).setText("A different label");
new Text(contents, SWT.BORDER).setText("World!");
parent.layout();
}
});
}
public void setFocus() {
contents.setFocus();
}
}
This will work with the form toolkit as well.

Hi Wayne,
since I'm quite newbie with Eclipse + RCP and my english is not so good, I
think it would be a hard work for me, but I would like to help in some way.
I offer my code and anything that could be useful for that, I would even try
to write something.
Anyway I think I haven't got the sufficient knowledge and experience about
this to write an article... I wish I could ;-)
