This is a multi-part message in MIME format.

Hi,

I have a form with a form text and a form message. But depending on the form
text the header is rendered somewhat strage.
e.g. create something like this

public void createPartControl(Composite parent) {

toolkit = new FormToolkit(parent.getDisplay());
form = toolkit.createScrolledForm(parent);
form.setText("Form & Title");
form.setMessage("Message", IMessageProvider.ERROR);
...
}

will cause the browser to display just "Form" and "Message" (see attached
image). "& Title" is missing. Same behaviour if you write "Form__Title" (_
as Whitespace). It works as expected with a single whitespace ("Form
Title").
It looks like the TitleRegion's dimension is computed incorrectly in those
cases.

A bug?

Regards,
Niels

Hi Niels,

to visualize the '&' character in TitleRegion (Label widget) a double
'&&' is needed - this is the same in SWT. Anyway, the described problem
is a TextSizeDetermination issue. Maybe you run into this bug:
256133: [TextSizeDetermination] Re-layouting for controls in a
ScrolledComposite
https://bugs.eclipse.org/bugs/show_bug.cgi?id=256133

HTH,
Ivan
