Hello All,
is there any possibility to represent HTML in some GEF Figure or much
better to use integrate some Browser features and representation to GEF?
I thought about using org.eclipse.swt.browser.Browser, but as I read it
is not possible/easy to use SWT Widgets in GEF (the only solution I have
heard about is to use screenshots).
Does anyone know a way to use the eclipse Browser class?
An alternative to get formatable text boxes would be to implement a
WYSIWIG text editor from the example my own
(org.eclipse.gef.examples.text - is this project really totally
abondoned?) my own. And afterwards integrate JavaScript and Flash which
are requirements, too. What is apart from possible, isn't it?
Thanks for your help.

if you will start doing this from scratch then you will have to do lot of work, but on the other hand you can alter the GEF and draw2d source code and build an extra feature of adding widgets also...
you can start it from the AbstractGraphicalEditPart which is been used by the RootEditPart and all the other edit parts.
create a method createWidget or something, like createFigure method..
like the primary layer, connection layer etc..(ScalableRootEditPart) create a composite layer and add it to the shell of the editor, like what we do for dialogs. give your own style to that shell so that it will look like an edit part (confine this shell to be inside the editor area).
now figures are fetched from getFigure-AbstractGraphicalEditPart which is been called from addChildVisual-AbstractGraphicalEditPart.
change the implementation in these and so in the interface also and may be you will be up with a widget edit part...
i have just gave a large idea to show you the possibility, but if you will try you can surely do this..,

Yesterday I just used the FigureCanvas of the GraphicalViewer as parent
of the widgets and the widgets as a member of my Figure. You can add
them like this. But zoom does not work (to solve with separated
zoom-events) and there are some event issues.
Your approach would make a difference?
I'm sorry, but I still don't get how to get a composite or common
Layer. How can you get a Layer that is a Figure to be a composite
between SWT and draw2d ... what is the main problem.
What are your refering to with "like we do for dialogs", don't they have
the application's (or GraphicalViewer's) shell as parent? It would be
nice to be able to overlay the widget with some Figure, solve some problems.
Thanks a lot for sharing your idea! We'll keep on testing.

my main theme was,
in gef all the figures are added to the primary layer which is also a figure type.
now the browser is of composite type...
so you can create one more layer of composite like the primary layer and call it composite layer. this layer will be used to add widgets.
if you will start this way later you can add other functionalities also..,
