Spring component
Gang,
When laying out many forms, one needs to 'push' components in vertical
or horizontal directions. They are supposed to 'fill all possible
space'. I don't think that this is available in Pivot, and I think it
would be reasonable to have it.
Cheers

I think you're looking for TablePane.

OTOH, after having looked at this:
http://java.sun.com/docs/books/tutorial/uiswing/layout/spring.html
I think that SpringPane may be a bit too complicated for Pivot:
"SpringLayout is...very low-level and as such you really should only
use it with a GUI builder, rather than attempting to code a spring
layout manager by hand."
Pivot may one day support a GUI builder, but you should still always
be able to code your UI by hand using WTKX (or Java). Since TablePane
already does what you describe, a SpringPane container may just be
superfluous.

I'd be reluctant to bake knowledge of a particular component type into
every container. That seems to pretty strongly go against good OO
design principles...

Well the way I see it, it is not a Layout, but a very very light-weight
components, that all containers know how to treat.

Yeah. That's intentional. :-) HTML is good for layout, and most developers
are familiar with it. Tables are great for a lot of different layout
requirements, and AWT/Swing has never provided one that is really easy to
use. We wanted to make sure that we brought HTML's ease of tabular layout to
Pivot.

I'm familiar with SpringLayout, though I have never actually used it myself.
We have lots of other container classes that parallel AWT layout managers,
so adding SpringPane would not be a stretch.
Feel free to enter a JIRA ticket for it (and assign it to yourself as well,
if desired). :-)

You guys are sooooo HTML oriented :-)
Could I recommend you to take a stab at trying the GUI designer in
IDEA?? Springs are really neat.
And you might pick up more ideas while you are at it...

TablePane facilitates this behavior. However, I think we need to add
an inner component class to TablePane to support the empty space (I
ran into the need for this the other day myself). Because of the way
row contents are defined in WTK (and HTML, for that matter), you
always need to define a component for a cell, even when you don't want
anything in that cell (in HTML, it amounts to creating an empty <td>
tag). We don't currently provide that, so you have to use a Label with
no text, or something similar. We should include a TablePane.EmptyCell
class that just takes up the empty space.
However, we could consider adding a SpringPane class to handle this
case - maybe TablePane is too big a hammer for this particular job.
Thoughts?
