FormPage in Visual Editor problem [message #125576] Sun, 04 June 2006 22:09 Go to next message

Greetings,

I've tried to edit FormPage subclass in Visual Editor:
public class PersonSummaryPage extends FormPage {

private FormToolkit formToolkit; // @jve:decl-index=0:visual-constraint=""

public PersonSummaryPage(String id, String title) {
super(id, title);
// TODO Auto-generated constructor stub
}

public PersonSummaryPage(FormEditor editor, String id, String title) {
super(editor, id, title);
// TODO Auto-generated constructor stub
}

protected void createFormContent(IManagedForm managedForm) {
FormToolkit toolkit = managedForm.getToolkit();
ScrolledForm form = managedForm.getForm();
form.setText("Empty FormPage");
Composite body = form.getBody();
toolkit.paintBordersFor(body);
}
}

On attempt to open this class in visual editor i get the following error
message in status bar:
java.lang.NoSuchMethodException(org.eclipse.ui.forms.editor. FormPage. <init>())

And the following error in .log:
java.lang.ArrayIndexOutOfBoundsException: -1

I took a closer look. It is a current restriction. FormPage can't be
subclassed because it doesn't have a default constructor (one that takes
no arguments). You can open an enhancement against VE to be able to
handle this.

But what if i make a subclass of FormPage with default constructor, and
then subclass it? Will it work? (Sorry for newbie question, i'm not yet
familiar with VE)

No, i tried that. That won't work either because FormPage expects a
FormEditor to be set on it. The problem is there is no FormEditor set on
it and so it thows NullPointerExceptions whenever you try to anything
with the FormPage.

Ok, but how do i design form pages in designer then? Create a form, design
it and copy source to form page?
Or any other workaround?

I don't know. I've never created a FormPage. I don't know what is
expected. There isn't any examples in the base Eclipse on what a
FormPage implementation looks like.

Check this:

In theory you can just design Composite and place it manually on
FormPage.
