How to wrap the description on the first page of wizard [message #1128130]

JFace Wizard lays out its size depending on various controls, in my case the description of the first wizard page is a long one causing the horizontal size of the wizard to be unnecessary long.
Is there a way to programmatically make it wrap, basically not have the description size taken into account for the horizontal size of the wizard. I see if i have a message (not description) set on this wizard it wraps well but description doesnt behave the same way.

I want to avoid any hard coding on the size because then it looks ugly on different 'resolution/text size' setting of the system.

Any relevant help will be greatly appreciated.

Hi,
I'd say it is not possible to achieve this with the standard WizardDialog as it extends TitleAreaDialog which creates a Label for the Title and a Text for the message:

You can just check the respective code of TitleAreaDialog:

   ...
   titleLabel = new Label(parent, SWT.LEFT);
   ...
   messageLabel = new Text(parent, SWT.WRAP | SWT.READ_ONLY);
   ...

That's why the message is wrapped whereas the title is not.

You might want to override the getInitialSize() method of TitleAreaDialog and introduce a MAX_DIALOG_WIDTH. But that would then be a hardcoded approach which you want to avoid.

After all you might be better off thinking about a shorter title.

Regards,
Thorsten
