Hello,

I would like to have a multiline textfield (preferably reziseable with
line breaks) in my GMF editor - like the notes I can attach in every GMF
editor. How can I realize something like this?

Greetings,

Ralf

Hello,

i found a TextCompartmentEditPart, which your compartment should extend.
But i don't know how to get the TextCompartmentEditPart automatically
generated. Does somebody know how to do this?

Hello Ralf,

Can you please file bugzilla request asking to add multiline labels support
to gmf code generation?
For now to make a label multiline you have to:
1. Modify code creating new WrappingLabel and call labelFigure.setTextWrap(true);
2. Modify generated label EditPart.getManager() to call

setManager(new TextDirectEditManager(this, WrapTextCellEditor.class, ???EditPartFactory.getTextCellEditorLocator(this)));

instead of generated:

setManager(new TextDirectEditManager(this, TextDirectEditManager.getTextCellEditorClass(this),
???EditPartFactory.getTextCellEditorLocator(this)));

Thanks, that helped. :)

Do your know how to enable text formating(like alignment right) in gmf?

And additionally if it is possible to color/underline/etc. parts of the
label text?

Greetings,

Joerg

Thanks - this works ... but the additional questions from Joerg are very
interesting, too :)

Hello Jörg,

There is an operation "setAlignment()" in WrappingLabel class, but is doesn't
work for my diagram.
Concerning rich text formatting in label - there is no such a control in
GEF/GMF AFAIK.

I tried using StyledText (instead of Text) in

/**
* A cell editor that manages a text entry field.
* The cell editor's value is the text string itself.
* <p>
* This class may be instantiated; it is not intended to be subclassed.
* </p>
* @noextend This class is not intended to be subclassed by clients.
*/
public class (now: Styled) TextCellEditor extends CellEditor {

/**
* The text control; initially <code>null</code>.
*/
protected StyledText text; <--

private ModifyListener modifyListener;

.... with corresponding changes is TextCellEditorEx.java and
WrapTextCellEditor.java. Unfortunately a can't edit the created
StyledTextControl.

Any Hints?

Greetings,

Ralf

Hi,

after some additional changes I am stuck at the point where GMF takes
over control ... and tries to cast to

org.eclipse.swt.custom.StyledText cannot be cast to
org.eclipse.swt.widgets.Text at
org.eclipse.gmf.runtime.diagram.ui.tools.TextDirectEditManag er.setEditText(TextDirectEditManager.java:468)
[...]

Maybe it is a good idea to support directly StyledText instead of Text
for labels?

Greetings,

Ralf
