Hi,
I am trying to implement a layout manager that can understand the
inline/block css attributes. It is very similar to a flowlayout except that
the block element take the whole space on their line, and inline elements
can be on the same line with other inline elements. I'm having a problem
with the text:
- how can I have inline text continue on the next line like in html? Figures
have to be inside rectangle, but in that case, that's not a rectangle
anymore, but two rectangles.
- how can I have the flowpage automatically resize the text figure so that
there is no empty space in my text figure? If I set the width hint to -1 it
works, but then it doesn't know about the maximum size so it doesn't wrap
any more...
Thanks,
David

Have you looked at the draw2d.text package? Specifically, FlowPage,
InlineFlow, and TextFlow.

That's fine. There is still a rectangular bounds, but containsPoint(x,y) is
implemented to hit-test the fragments on each line.

I'm not sure what you mean. You mean if a line does not extend to the right
margin, you want it stretched there anyway? I would imagine this is going
to be useful when hit-testing and placing the caret.

I did, I am actually using them.

Can you explain in further details? What layout should I use, the
paragraphlayout wraps, but not the way I'm interested in. Here is an
example:
"Element 1 Element 1 Element 1 Element 1 Element 1 Element 1 Element 1
Element 1 Element 1 Element 1 Element 1" "Element 2"
If you make your email client window small enough, element 1 will be on two
lines, element 2 will start right after on the same line. How to achieve the
same layout for Element1 and 2 in GEF?

Ok so what happens is that the main layout gives a widthhint to the flowpage
figure. Then the flowpage figure will use all of it, even it could use a
shorter width because the text is shorter than this width. So my text figure
will take more space than the text itself.
Now if I give a widthhint of -1 it will never wrap, because it doesn't know
when to wrap, since there is no hint to tell.

Sounds like a FlowPage, with 2 TextFlows as children.

Ok, but Element2 could be something else than text, like an image for
example. And both elements are linked to different EditParts, it means the
FlowPage must be the figure of the parent EditPart. So if the parent must be
a FlowPage, that means all my figures need to be FlowFigures? I looked at
the hierarchy of FlowFigure, it has BlockFlow and InlineFlow as children.
But InlineFlow should not be subclassed, so how can I have inline behaviour
with non-text figures (inline in css means the element can coexist in the
same line with other inline elements and his size is minimal, while a block
element takes the whole space and is always alone on its line)?
Thanks,
David

If you want an image inside a flow, you just create some ImageFlow figure,
or FigureFlow proxy to any generic draw2d Figure. Yes, you must subclass
and violate the warnings. These figures were provided as a preview of what
is upcoming in 3.1. Your subclass will work in 3.0, but may get broken and
require changes in 3.1.
