Draw2D, which is the painting and layout portion of GEF, has added a new
package for rendering WYSIWYG documents. Currently, the support is for
paragraphs of text which can contain multiple nested styles, such as
different fonts and font sizes.

Can you please tell me where I can find example of using this? Will that in
the Logic Editor Example?
Thank you.

Use anonymous login, via "pserver", to the /home/tools CVS root.

Can I replace the Label and its TextCellEditor in the Logic Editor Example
with the new WYSIWYG editor?
Are those related? Or they are totally different things.

//Also, I would override getFont() here to return a Font that is some
percentage of the parent's Font.
//But then you get into this big resource management nightmare, that makes
me want

class SuperInlineFlowLayout extends InlineFlowLayout {
//uses AdjustedLineBoxes instead of LineBox
}
class AdjustedLineBox extends LineBox {
void makeBaseline(int baseline){
//this method would have to adjust the baseline that it passes to its
child boxes.
}
}

No relationship. StyledText widget is very limited in what "styles" you can
render. For example, you cannot change the font, or add borders around
regions of text, or render Tables. Of course, you can't do those yet with
draw2d, but someone *has* already done so in their extensions to these
classes, which were available internally at IBM.

Source editing used to be using a RichText control. But, Windows RichText
was a piece of crap, so Eclipse includes a StyledText widget, which was
suitable for their needs. If you need RichText support, this is as close as
you will get. It would be great if you wanted to help out with these new
classes.

curious as to the technical/architectural reasons why the package is part of
GEF/Draw2D and not SWT/JFace. Finally, I don't think you mentioned the name
of the new package itself (a Javadoc url would be appreciated too). Thanks.

Not viewer, editor. IBM's Page Designer is an HTML/JSP editor built on top
of GEF. But the released package is only concerned with viewing. Any
editing support would go into the GEF plugin perhaps.

SWT/JFace is part of the base Platform. The Platform's focus is source-code
Editors like the java editor. The Platform is mostly developed by OTI.
GEF/draw2d was developed at IBM initially for internal use with Eclipse.
Draw2d is used as a platform for rendering text because it allows you to
compose lightweight figures that layout in an efficient way and paint using
double-buffering. Several complex issues have already been implemented in
Figure (such as coordinate systems, hit-detection, various notifiers), and
it makes sense to take advantage of this.

Thanks.
The package is org.eclipse.draw2d.text. For JavaDoc, you must go to the GEF
build page, download and install the SDK onto Eclipse 2.X, and open the
integrated help system. Our generated JavaDoc is not released onto our
website (which is just a CVS folder) because it would consume a lot of
space, and the builds aren't setup for this.

Try ToolbarLayout in Vertical orientation.

Randy,
This is great, I could really use a replacement of StyledText with
richer markup possibilities (doc or rtf style) .
IMHO, What is missing in the examples right now is edit capability .
Also, tables and indentation/interlinea support would be nice to have.

I think that stuff is missing in everybody's opinion :-). We have to start
somewhere. I can tell you how IBM implements page designer (since this is
public knowledge). There is a special SelectionTool that manages keyboard
entry and the Caret location. There is a Model that is a DOM. There are
EditParts which synchronize the DOM to the draw2d Figures. This is how GEF
works, and it is the logical extension of GEF into text documents.
Are you familiar with EditParts?

We also think about tree control with rich text support (something like used
in MS OE). How do you think is it worth for community? Anyway we will need
something like this in our application.
One thing we are dreaming about is an ability to drag'n'drop from editor to
palette. I mean, if you define some complex object in editor space, select
needed things and then DND to palette to extend some reusable templates
category... Is it possible to implement?
Last but not least - antialiasing. Any rumors about this? I think that that
is the only thing that one need to produce first class applications using
GEF.

I didn't understand this. What do mean by tree control? Are you talking
about "owner draw"?

There are some SWT peculiarities with native Drag. You can do this. See
TransferDragSourceListener, TransferDropTargetListener. But, once you
decide to drag a part using native Drag, you will be forced to use native
drag simply to move the part within the graphical viewer. This can be done
as well, but you will no longer be using Tools, just a DropTarget.

Nothing from the SWT team. Please see my previous post requesting that
people CC themselves to the bugzilla to give it more "votes".

Hi,
I took a look at the examples in draw2d and have some questions:
1. How do I switch to an editor mode?
2. I would like to add a toolbar for italic, bold, font size, font type.
What would you suggest as a starting point? Do I use the
WorkbenchAdvisor? Is there a support for selection Listeners?
3. Also what would you suggest for adding tables, lists and images?
4. What would be the appropriate way to access the model of that editor.
I would like to serialize the content to XML. Something like this for
instance:
<paragraph><bold>ILP</bold> - <italic>Integer Linear
Programming</italic>: When one or more variables in an LP problem must
assume an integer value we have an Integer Linear Programming (ILP)
problem.</paragraph>
5. Would it make sense to use EMF and model the different FlowFigures
and the genmodel generate the WYSIWYG editor?
Greetings,
Nima

Hi,
Is there a way to add a SelectionListener to a FlowFigure? I want to
allow the user to select text inside a flow figure and change it font
settings. Or maybe selection the whole figure and changing its paramters.
Greetings,
Nima

I have Bold, I, Underline infrastructure in place, and will release it today

The difficult task is DEFINITELY writing the commands that edit the
document. EMF could not come close to generating the correct commands. For
example, given:
<B>bold text</B>some more text.
This looks like:
+ Document
+ Container(Bold)
-TextRun(bold text)
- TextRun(some more text.)
If the user selects "some more text.", and invokes bold, the text must be
re-parented to the existing nearby TextRun which is already bold, giving
you:
<B>bold textsome more text.</B>
+ Document
+ Container(Bold)
-TextRun(bold textsome more text.)
And that's a simple scenario! Here's another:
<U><B>bold text</B></U>some more text.
In this case, the <U> and <B> would have to get flipped around to simplify
the document.

Selection lives in GEF, not draw2d. This function will be released today or
tomorrow. Please check out the example.text project.
