How to create JTree horizontally?

Can I create a GUI tree which has its stem horizontally using java?
TIA.

I'd take a look at swinghelper's transformer, which allows you to rotate swing components. It is an experimental project, but still worth a look:
http://weblogs.java.net/blog/alexfromsun/archive/2006/07/jxtransformer_t.html
You could also override paint(), and tweak the transformation of the passed graphics. You would also have to override the get*size() methods, and translate the coordinates of the mouse events.

How to create a horizontal multi column menu?

We are trying to create a horizontal menu, just like the one at Oracle site ( [http://www.oracle.com/us/index.html] ) with links in multiple columns in each menu item. Can you please suggest how to do it? We have tried using the navigation model but could only create single column menus.

Put the links in a form and set the rows and columns properties of the Form.

How To Create Gradient Horizontally, Top to Bottom

Within Illustrator CS4, I created a rectangle.
Is it possible to fill the rectangle using a gradient with the gradient occurring from the top of the rectangle towards the bottom edge, essentially having long strips of color from left to right within the rectangle?
It appears that the gradient tool fills in the rectangle using vertical bars, and I would like to have long horizontal strips.
Is there some way to rotate the fill so the gradient happens in the other direction?

look in your gradient panel - window -> gradient
That middle field with the 0 in it is the angle of your gradient. you want 90˚ or -90˚

How to create a horizontal full screen banner filled with sideways moving graphics?

Well, that is the question.
Spec: The banner should be the width of the page (or the screen),the width should be about 10% of the screen height, and a fixed series of pictures or graphics should be continually moving gently sideways inside this banner, filling the banner.
Note: I have Studio VII extensions at my disposal, and a whole bunch of others, but since I am new to Dreamweaver, I have not tried them all out; and so far, Studio VII inserts or behaviors have not answered my question (or I did not persist hard enough to get one of them fulfill my needs).
Slide Show Magic? Vertical or Horizontal Scroller? ShowPicLayer? Image Gallery Magic? ...all by Studio VII.. or anything else, as long as it gets images moving sideways in a banner.

First you need to build a container for your header and since you want it to be liquid (flex to size of viewport), you'll need to use a width in percentages rather than pixels.
Example of liquid header can be seen here: View page source to see the CSS and HTML code.
http://alt-web.com/DEMOS/Liquid-header.shtml
Second, use Flash to build your moving picture banner. For detailed info on that, consult the Flash Forum.

How to Create a Horizontally Scrolling Portfolio

There are a couple of great portfolio sites in the Adobe Site of the Day with a series of images that move to the left as the user scrolls down. The one I like best is not a one page website. It has a navigation menu that stays pinned to the top and each page in the site stands on its own as in any other website. This is it: http://www.erickusters.nl/
I admit I'm a little crazy to be wanting to tackle something like this when I've never used parallax scrolling at all but, like this designer, I have worked in a wide variety of media and have a lot of work I want to present.
I have watched every tutorial I can find and played with the program a fair amount but I haven't been able to figure out how to achieve this. Somebody on one website suggested making the website extremely wide but I tried looking at this site's source code and it doesn't look like that's what he did. . . although the code was almost impossible for me to make heads or tails out of so I may have missed something. (I know html and basic css but this is beyond me.)
Any guidance on this?
Thanks!

How can I create a horizontal scrollbar with a centered thumb that scrolls content from both sides?

I am having trouble figuring out how to create a horizontal scrollbar component either by itself or nested inside a data list component that will have it's thumb centered in the track when running and reveal content from either the right or left side when the thumb is moved. The furthest I have managed to get is to create a data list component with a scrollbar component inside that has a centered thumb that reveals content from the right side of the list (0 through 10 of the items) but only reveals blank area when tracking the other way. Is there a way to create say… negative items in the data list… 0 through -10? Or am I approaching this the wrong way. Please help. Thanks.

Mykola,
Thanks. I guess I was hoping for an answer that addressed my question from a designer's point of view rather than a developers'. As a designer with over ten years experience using Adobe products for print work it is difficult to understand why "centered" is such a complicated concept when designing art for use on the web. It is so frustrating to realize that most containers for images and text can only be resized by pushing and pulling handles located on the right and bottom; Catalyst seems like a great start but if Adobe really wanted to impress the "design" community it might consider putting all that supercharged code underneath the hood of some more familiar "design" tools. Maybe a "catalytic converter" would allow the introduction of a "centered" tool for every element.
After all, why is it literally twenty-five times more difficult, requiring the use of three additional programs to create a component that functions exactly like a typical data list and scroll bar with the exception that the thumb is "centered" on the track and reveals images from both the right and left. For that matter why not also have as an option a thumb that snaps to the bottom of the track and reveals images from the top… and one that snaps to the right and reveals images from the left when you run the project? It just seems so logical to expand the scroll bar component to include these options.
I am very glad to have Catalyst and will redesign my project to fit within the constraints of the tools available in the program but it seems that if Adobe is really serious about Catalyst being a window into the world of web design for designers/AD's that perhaps it might benefit by focusing on what might improve the program from the designer's point of view. I hate to say it but the Catalyst forum is already rife with answers to questions that are riddled with code… Literally. And to be honest most designers don't have the time to decipher that code. As a designer I work regularly and have a deep understanding of Photoshop, InDesign, Illustrator, Acrobat Pro, Final Cut Pro, Final Draft and modo. I do hi-res assembly, retouching, design and layout, identity, production, 3D modeling and rendering, video editing… and before I switch to using Catalyst for web mock-ups I am going to need a more "designer" friendly set of tools and definitely a "centered" control.
I really think Adobe is fantastic. But I also think it could take a lesson from a great little company called Luxology. I tried learning 3D modeling and rendering for years with programs like Lightwave, Maya and others, always with mixed results. Then Luxology came along and actually delivered on their promise to create a 3D program for artists. What was the factor that made all the difference? Well, besides the Apple award winning interface and sets of tools it was the training available on their sight. The program itself ships with thirty-six hours of quicktime movies. And hundreds more hours available for download. I have never yet not been able to quickly and easily find an answer to a question I had about how to accomplish something in modo. You know how long I have already spent on Adobe TV searching through videos and on the Catalyst forum searching through topics trying to get an answer to what I thought was a very simple question? Way too many. If I have a question about a Luxology product that I can't find the answer to do you know what I do? I call Brad Peebler, the President of Luxology. I'm not special nor do I work for some special development house with special privileges that is simply their policy. And that policy has paid big dividends. Both ILM and Pixar has licensed their technology.
Well… I apologize for this long response but I really think that if Catalyst is going to attract the market it wants that it will have to consider putting some designers on the development team. After all… Isn't that what the promo videos tout… Finally a web design program for designers. Well, I guess we'll see.

How to create Horizontal scrollbar

I am using Form6i, how to create a horizontal scrollbar for a multi-record block?
Thanks!

A horizontal scroll bar is not an object that you can drag or resize like a vertical scrollbar. It is implicitly created when needed.
To get a horizontal scroll bar, you have to place the items you want to scroll on a STACKED CANVAS and set property Show Horizontal Scroll Bar of this canvas to Yes.

How can I create a horizontal line under a line of text?

Hi,
I have FM 12.0.3.424.
Does anyone know how to create a horizontal line under heading text that is the width of the page? Similar to creating a border but without the top and sides.
Is it even possible?
thank you in advance!

Use the "Frame Below" attribute in the Advanced tab of the Paragraph Designer for your heading tag to use a named Reference Frame from your Reference page. If you're using the default templates for your documents, you could try the Single Line selection (or make your own).

Creating a Horizontal Thermometer

Does anyone know how to create a horizontal thermometer display for the Front Panel (instead of the vertical one)? The closest thing I have at the moment is using a horizontal fill slide and changing the color to red. Is there any better way than this?
Thank you,
Joshua
PS: I'm running LabVIEW 8.2

A horizontal progress bar would have a bit more of a 3D effect than a fill slide.
(You could even add a decorative red LED to the right for some cosmetic effect ).

How do I create a horizontal nav-bar with CSS, set to an exact width?

I have a problem that I need help with. All I need to do is
to create a simple text-based horizontal navigation bar using CSS.
I have seen many CSS tutorials online about how to make a
horizontal navigation bar using unordered lists, but they all seem
to either set the bar to be centred or to the full width of the
page, or if they do set it to be a certain width, then the buttons
within that width are centred within pre-defined widths for each
one.
Unfortunately none of these help me - let me explain my
scenario...
I have an area that is exactly 700px wide. In this area I
want to put 5 text hyperlinks.
I want the first text-link to be aligned to the left of my
700px width, and I want the last text-link to be aligned to the
right of the 700px width.
I want the spaces between each of these text-links to all be
the same.
The only definite known width is the overall 700px. I will
not know the width of each text-link, as (a) they are all live
text, and (b) the phrases for each could change.
I have mocked up a quick diagram showing in more detail
precisely what I mean:
http://www.nothowitlooks.com/temp/navbar.gif
Can anyone please help me with this?
Thanks.

Only in your fantasy. In practice there are always some
limits enforced
by the used material or technology. You simply can't violate
such basic
rules and laws, even if you would like to.
>Whether you use text, images, tables, CSS, or even

both your client's and

It always looks good on paper, but not every design can be
turned into
practice. This not only applies to web design, but to almost
every kind
of development. Often enough you have to find compromises or
workarounds
if the engineers say "won't work". The problem is that many
designers
don't understand this or don't want to. They're just thinking
and living
in their perfect theoretical world, but have no idea of how
things work
in the real world. And many theoretical things simply don't
work there.
Each medium has its own rules and laws. Some things may work
well for a
printed paper for example, but not in the Web and vice versa.
Of course
you can try to break these rules, but you'll definitely fail.
>You should not compromise your
>design because of a lack of coding knowledge.
It's not lack if coding knowledge if you refuse to try things
that are
impossible or don't make sense. It's quite the opposite,
because you
don't have to waste your time with something that won't work
at all.
>If you don't know how to do it
>yourself, then find out how to do it (which is what I was
*originally* trying
>to do here, remember?).
Quite easy. Surf the web, and if you see something like what
you want,
just have a look at the source code or post the URL here. If
it can be
done, then it already has been done. Just show us an example
and we'll
happily explain it to you.
> Secondly, no, a client does NOT have to accept that
"some things simply can't
>be done or don't make any sense in the Web".
Sure they have. The client is not always king. And if they
insist on
stupid things and always know it better - why the hell are
they hiring
you instead of doing it themselves? If they want their work
to be done
by an expert, they should also _listen_ to that expert and
let him do
his work properly instead of telling him how he should do it.
That's not
going to work.
>Like I said earlier, some clients

>attempts to tell them so only serve to convince them to
take their work, and

that simple.
Let's say you want a little film to be made about whatever.
Would you
tell the director where he should position the cameras, the
lights and
all the stuff? He already knows _what_ you want to get, so
why don't you
just let him decide _how_ to do it? It's his job! And if he
says that
filming directly towards bright sunlight usually doesn't work
well, you
should respect his expert opinion.

You asked for advice and you got proper answers. We really
don't need
people here just looking for the answers they want to hear.
Often enough
people are coming here looking for a cure to a particular
problem, while
it would be much easier to avoid that problem right from the
beginning.
Of course if they don't want to hear such alternatives -
their problem.
> Secondly, I was not aware that "regulars" to this site
had any special
>"insult-free privileges" or suchlike that newcomers did
not.
It's not the best idea to bite the hand that feeds you. It's
the group's
regulars who answer almost all of the questions here. And
most of them
also know how to use a killfile.

So do we. If someone wants something that's not possible or
not going to
work, we'll "make our opinions known". After all that's what
a free
discussion board/forum/group is for.

Want to try again?
With pure CSS and text links it can't be done within the
given
constraints. I even doubt that it's possible with a table. So
either
drop the fixed 700px width or the equal space between the
buttons.

You can keep the 'e'. In German we have more than enough of
them.
And if you would be familiar with web design, then you would
have known
where this ironic "error message" came from.
Your turn.

How can create a JTree with cellRender is checkbox realized multiple selec

How can create a JTree with cellRender is checkbox realized multiple selection function.thanks for every
one's help.

Hi,
1. Create a value node in your context name Table and set its cardinality to 0:n
2. Create 2 value attributes within the Table node name value1 and value2
3. Goto Outline view> Right click on TransparentUIContainer>Apply Template> Select Table>mark the node Table and it's attributes.
you have created a table and binded its value to context
Table UI properties
4.Set Selection Mode to Multi
5.Set Visible Row Count to 5
6.ScrollableColCount to 5
In your implemetaion, you can add values to table as follow:
IPrivate<viewname>.ITableElement ele = wdContext.nodeTable().createTableElement();
ele.setValue1(<value>);
ele.setValue2(<value>);
wdContext.nodeTable().addElement(ele);
The above code will allow you to add elements to your table node.
