Hi,
I have read a lot of the available GEF, SWT, JFace documentation and am
currently running the "Shapes" example via the debugger to get an
understanding of the overall structure.
I would like to create a tool in GEF which is probably a straightforward
enhancement to the "shapes" example.
I am relatively new to Eclipse and GEF (and Java!) so I would appreciate any
pointers on how the following specification could be met.
My proposed tool would involve:
1/ Removing the ellipse shape
2/ Enhancing the rectangle shape so that a user can enter/edit text inside
it
3/ The text would all be in the same font (although if different fonts are
possible within the other constraints presented here, please tell me how!)
4/ The text would wrap-to-next-line within the rectangle width
5/ The text may have newlines in it (in which case new paragraph starts as
is usual)
6/ The text would get a vertical scrollbar if it exceeds the rectangle
height (and of course scrollbar would disappear if resized rectangle
accommodates entire text)
7/ Ideally, if the focus is not on a particular rectangle, a click to its
text would place the cursor immediately at the text position clicked on
(unlike the "flow" example in which the first click causes the entire text
to be selected).
From what I have read, one solution might be to manage instances of
org.eclipse.jface.viewers.TextCellEditor
as children of the rectangles.
Is there a class available which incorporates the rectangle *and* the
contained text... or is it better to keep the rectangle separate from the
contents, maybe for the purpose of controlling the positions of the handles
on it?
Please comment.
Thanks, Martyn.

Have a look at the logic examples StickyNote, which will meet nearly all of
your requirements.

Multiple ways to do this. We have a modified logic example that does this
without using celleditors. The code is unreleased so far.

Use a FlowPage, with InlineFlow and TextFlow figures to manage the nested
styles.

org.eclipse.draw2d.text package handles this.

ParagraphLayout handles this too.

You'd have to put everything inside a scrollpane figure.

This is planned for 3.2 as well.

FlowPage and BlockFlows in general support borders, although there is a
minor bug in 3.1 which was fixed in HEAD. If you just need a rectangle and
for the text to be placed inside, you could use borders. The correct place
to use the border might be at the scrollpane.

Hello, this post is very interesting, it could be a solution for my
previous question. What is the solution to don't use cell editor? Have oyu
a simple exemple?
Thank you !
