How to set mutable cell width and height in a jlist?

Hello,
i wrote a jlist cell renderer object to able to render a jlabel for the unselected items and a wide and high jpanel with images when an item is selected.
The jlist render all items at the same dimension.
How can i change this built-in behavior?
i printed the items preferedsize:
java.awt.Dimension[width=340,height=140]
java.awt.Dimension[width=275,height=75]
java.awt.Dimension[width=275,height=75]
java.awt.Dimension[width=275,height=75]
java.awt.Dimension[width=275,height=75]
java.awt.Dimension[width=275,height=75]
java.awt.Dimension[width=275,height=75]

ok, i give for every index pos a fix jpanel object, and it is working.
What i would like is a mouse selection and the selected item/cell should be rendered by a component with different dimension (containing more information). but this doesn't work.
Is it possible, that the JList cashes the cells dimensions???

i just want to change a cell for another when i click on it.
there are names in the jlist. after having click on one of them, a description panel could be appears in the list instead of the short name. it' a simple ui effect, i think.
is there any other way than write a custom jlist implementation?

How to set a minimum width and height for a stage or scene?

Hello,
Does anyone how to set a minimum width and height for a stage or scene?
I tried listening for width/height property value changes and then adjust the width/height if necessary, but that causes unpleasant flickering of the window.
In JavaFX 2.1 beta SDK for Mac OS, the Stage class has setMinWidth() and setMinHeight() functions which work very well.
I'm wondering what's the equivalent way to do that when using the FX SDK for Windows.
Any help is appreciated!
Thanks.

I was wondering how to enforce a minimum stage size with JavaFX 2.0.3.The same flickering way you are currently doing it. See: http://javafx-jira.kenai.com/browse/RT-15200 "Need a way to set the minimum size of a window"

How do I save the width and height of a photo for repeated use?

How do I save the width and height of a picture for repeated use, rather than having to enter it each time in the 'new file' box?
Thanks, Ed Jackson.

It could be that I'm older and have forgotten. I'm now 73 and will admit I have forgotten many things over the years. I have been using Photoshop since Photoshop version 3. And can not really recall which features or changes were made in ever version of Photoshop I have installed. Adobe has added many features over the years. The number of bugs introduce has also greatly increased after CS3. "New Doc Sizes.psp" in your user id preferences is edited using the two buttons in the new document dialog.
As for guide lines in new documents Photoshop CS6 or CC seem to add some for video file presets with guide lines. I do not know how to edit or add guide line to new doc presets. Guide line actions are easy to create. I have also seem some guideline in new documents when I did not expect any perhaps a new bug. Photoshop like most software has bugs. If you do not see Adobe new presets perhaps you copied an old "New Doc Sizes.psp" over Adobe's newer default file or Adobe migrared you presets and wand wiped their presets out. There are bugs. Close Photoshop down and rename your current "New Doc Sizes.psp" in you user id Photoshop cc preferences folder and start Photoshop it will add a dedault "New Doc Sizes.psp" file see if you see Adobe new presets in the new doc pull down when you select video and film...

Excel 2007. OLAP pivot. How do you resize dropdown width and height?

Excel 2007. OLAP pivot. How do you resize dropdown width and height?

hi,
I'm afraid we can't modify that property in Excel. Someone had suggested to use a custom combo box to replace the built-in drop-down. However it will lose the features which are only available
for built-in drop-down.
Hope this
thread will give you some ideas. Thank you.

How to set the BARCODE width and length for label printing..

Hi All,
How to set the Code 39 barcode label format in the sizxe of 0.20" * 1.4". By default while printing barcode size exceeds my current requirement. Please let me know to customize the size of barcode labels.
Thanks.

I don't know what you mean by "Code 39" because my Output Designer software doesn't offer that barcode (or do you mean "code 3 of 9?). In any case, are you trying to control the size of the text (which is what I think of when you refer to "label")? If you are, then just change the font & size. If you are wanting to modify the physical characteristics of the barcode itself (height & length for a certain number of characters) then you are probably out of luck. Or at least in for some trial & error.
There are a series of "barcode.xxx" files in the 'config' folder where Output Designer was installed to. These are text files that contain the physical characteristics of the various barcodes for various printers. The parameters that you would be interested in is the height and width of the bars (black & white). For example, a barcode might be defined as .400 high with narrow bars 3 "dots" wide, wide bars 9 "dots" wide and white space the same or different. Presumably changing these values would affect the generated barcode. For example, in this example the wide bars are 3 times the width of the narrow bars so I would assume that relationship would have to remain. To make the resulting barcode shorter you would then use 2 for the narrow and 6 for the wide.
You would have to make the change in the file(s) that would be used for your printer(s).
There are four width values for each of the parameters. Most of the barcodes only use 2 but some have 4. I'm assuming that when there are 4, like in "4 8 12 16", that the barcode definition has 4 different widths of bars and/or spaces.
There is no guarantee that the scanning hardware & software will "see" and interpret the resulting barcode correctly.

How to get WIDTH and HEIGHT fields from applet tag?

I am developing an applet using JDK1.1 (to ensure microsoft jvm compatability).
A problem I'm facing is that there are no getWidth() or getHeight() method for Applet in 1.1, so I am hoping I can get this info from my html: <APPLET CODE="MyApplet" WIDTH=600 HEIGHT=856></APPLET>
getParameter didn't work, so does anyone have any ideas how I could get the width and height?

Write a jpeg decoder that can figure out how to determine the width/height of a jpeg file? Google it.
Or if you're really lazy, load each jpeg using the

Obtain width and height in device central?

I'm using device Central with Flash CS5.
How do I obtain the width and height of the device being simulated?
I need to write some special code to handle screen size in device central - as my application is already able to obtain the screen dimensions when run on a real device.

I need to know if this is possible, too!
Hopefully this is working somehow.

Setting the preferred width or height of a ListView using css ?

Is it possible to set the preferred width and height of a Node (a ListView) using css ?
Just in case I tried with:
.my-list {
-fx-pref-width: 130;
-fx-pref-height: 100;
but it does not seem to work.

Not that I know of. Searching for "prefWidth" in the CSS documentation yields no results. JavaFX layout is typically not managed by CSS, but by FXML and/or Java. You can set the prefHeight and prefWidth as attributes in the FXML file:
<ListView fx:id="..." prefWidth="130" prefHeight="100" ... />or in Java:
ListView<String> listView = new ListView<String>();
listView.setPrefWidth(130);
listView.setPrefHeight(100);

Width and height of ROI

How can I change the Width and Height of ROI ? Im attaching the VI it does the edge detection.. please help
Thankyou

The line camera takes pictures of a single line over and over again as the object moves underneath it. You can build up an image of the object by stacking the lines in a larger image. If the line of the camera goes straight across the material being measured, you can measure the width with every line.
Yes, you can use a 100 meter cable with a GigE camera.
Red lighting is just the most convenient. Red is the easiest color to generate, and can easily be filtered to eliminate other light frequencies. Using colored lighting helps increase the contrast between the lighted areas and the background.
Your image indicates a max speed of 180 m/min, which would be 3 m/sec. If the camera acquires each line at 24 kHz, that is 24000 lines/sec. Divide the two to get 8000 lines/m, or 8 lines/mm. If your computer can keep up, you could make a measurement every 0.125 mm of your material. That probably isn't practical, but you should be able to make the measurements at the rate you need.
Almost forgot, the width is 1900 mm. With 4096 pixels wide, you get just over two pixels per mm. That means your measurements should be accurate to the nearest mm.

Help to edit width and height of menu?

http://www.ivoog.com/link4
How can I edit the width and height of this menu so the
background image fits? Please explain and give code if you can.
Thanks!
Here's the pictures for the menu:
http://www.pics.ivoog.com/boxs1.gif
http://www.pics.ivoog.com/boxs2.gif

Your approach simply isn't going to work.
The background image is a fixed width. It will not shrink or
grow like the
text in front of it.
The background image is wider than the word "pie" but not as
wide as the
word "sigh".
So, if you add padding to the left and right of the link to
make the whole
background show behind "pie", the same padding is added to
"sigh". Now the
"sigh" link is much wider than the background image. Because
your
background image repeats, you see the left edge of the next
repeating one
behind sigh.
If you remove the padding to make it so you see just one
image behind
"sigh", now the padding around "pie" is too narrow to see the
whole
background.
You could try giving each link a class and having a separate
padding for
each word, but all that is pretty useless because different
people have
different text size settings in their browsers.
In some browsers, the words will be bigger than the
background image.
In others, the words will be small and you'll only see part
of the
background.
The free tutorial I sent you is just that, a tutorial.
You do the work, you have the copyright.
If you are not interested in that one, here's another idea.
You can use borders and simple background , like a gradient,
to make a tab
that looks just like your tab images and sizes along with
your text...no
matter how long the word is and no matter what size the text
is.
Here's the free tutorial.
You don't even have to do the whole thing, just the first
part where it
shows you how to make links that look like image buttons.

How to set field width and height at runtime programatically?

Hi all,
I want to set the width and height of a report field by reading its values from the database table.
Is it possible in Oracle reports?

Any help will be highly appreciated.
Thanks .... Best Regards

You cannot give it a specific value. During design you can set Horizontal and Vertical Elasticity properties to Variable, so the items are automatically scaled when running the report.
