Slice transparency on save single slice / background color for artboard

Hi,
I know, I am missing something obvious in Illustrator CS5 here:
- how do I set the transparency for a slice(e.g. for a red background color)?
- how do I set the background color for a particular artboard?
Greetings
Michael Kastner

1. differs depending on the format you want to export. For GIFs, use "Save for Web and Devices"
2. Draw a rectangle on the artboard in the desired color.

How to give Common Background color for all JPanels in My Swing application

Hi All,
I am developing a swing application using The Swing Application Framework(SAF)(JSR 296). I this application i have multiple JPanel's embedded in a JTabbedPane. In this way i have three JTabbedPane embedded in a JFrame.
Now is there any way to set a common background color for the all the JPanel's available in the application??
I have tried using UIManager.put("Panel.background",new Color.PINK);. But it did not work.
Also let me know if SAF has some inbuilt method or way to do this.
Your inputs are valuable.
Thanks in Advance,

It is not the fault of NetBeans' GUI builder, JPanels are opaque by default, I mean whether you use Netbeans or not.Thank you!
I stand corrected (which is short for +"I jumped red-eyed on my feet and rushed to create an SSCCE to demonstrate that JPanels are... mmm... oh well, they are opaque by default... ;-[]"+)
NetBeans's definitely innocent then, and indeed using it would be an advantage (ctrl-click all JPanels in a form and edit the common opaque property to false) over manually coding
To handle this it would be better idea to make a subclass of JPanel and override isOpaque() to return false. Then use this 'Trasparent Panel' for all the panels where ever transparency is required.I beg to differ. From a design standpoint, I'd find it terrible (in the pejorative sense of the word) to design a subclass to inconsistently override a getter whereas the standard API already exposes the property (both get and set) for what it's meant: specify whether the panel is opaque.
Leveraging this subclass would mean changing all lines where a would-be-transparent JPanel is currently instantiated, and instantiate the subclass instead.
If you're editing all such lines anyway, you might as well change the explicit new JPanel() for a call to a factory method createTransparentJPanel(); this latter could, at the programmer's discretion, implement transparency whichever way makes the programmer's life easier (subclass if he pleases, although that makes me shudder, or simply call thePanel.setOpaque(false) before returning the panel). That way the "transparency" code is centralized in a single easy to maintain location.
I had to read the code for that latter's UI classes to find out the keys to use (+Panel.background+, Label.foreground, etc.), as I happened to not find this info in an authoritative document - I see that you seem to know thoses keys, may I ask you where you got them from?
One of best utilities I got from this forum, written by camickr makes getting these keys and their values very easy. You can get it from his blog [(->link)|http://tips4java.wordpress.com/2008/10/09/uimanager-defaults/]
Definitely. I bit a pair of knucles off when discovered it monthes after cumbersomely traversing the BasicL&F code...
Still, it is a matter-of-fact approach (and this time I don't mean that to sound pejorative), that works if you can test the result for a given JDK version and L&F, but doesn't guarantee that these keys are there to stand - an observation, but not a specification.
Thanks TBM for highlighting this blog entry, that's the best keys list device I have found so far, but the questions still holds as to what specifies the keys.

Problem in Setting Background Color for JButton

Hi,
I am using Background color for JButton (color is selected from the customized JColorChooser created by us) where it contains the option of transparency. If we choose light color, then the background is set to JButton, but when we mouse-over the JButton, other components inside the container (JPanel) is getting displayed inside the button.
Can anyone help to sort out this problem.
Thanks in advance.

Hi,
Here is the code.
DialogWrapper is JDialog and ColorEditorPane is JPanel.
DialogWrapper dlg = new DialogWrapper();
ColorEditorPane colorPanel = new ColorEditorPane();
colorPanel.setValue( _data.getTransparentColor());
dlg.showWrappedDialog( colorPanel, "color_help", "color_dialog" );
if( dlg.isOK())
Color chosenColor = (Color) colorPanel.getValue().getContent();
_data.setTransparentColor( chosenColor );
_transparentColorDisplay.setBackground( chosenColor );
_transparentColorDisplay.setOpaque( true );
this.repaint();
this.doLayout();
this.validate();
}I've several components like JCheckBox, JRadioButton, JTextField in "this".

Set property for background color for JButton

I am attempting to change the colors of the UI for JButton. The change does not appear to be taking. The reason appears to be that JButton, and for that matter JLabel setOpaque(false); How can I globally change this to setOpaque(true);
Second is there a way to save the default property hash table after the changes are made so that it will run the next time the program is executed.

Thank you for responding. I don't feel that I have been clear in the statement of the problem. I have written a medium size desktop application(20,000 statements). I am trying to customize the color scheme by modifying the default laf properties color entries. I can modify JPanel through a put to the properties hash table. When I attempt to change the background color for JLabel and JButton it doesn't seem to take. I believe that the reason it doesn't take is because opaque(false). Is there a property that allows the overide of opaque to true or do I have to change all of the numerous JButtons in my program.
I have decided to store all changes in a file and make the changes at the point that the program initializes each time its run.
I am not looking for specific code but an approach.
I would appreciate your advice.

now i want to set background color for headers i
ex:PARTY_ID,PARTY_NAME,AGENT_ID,TYPE_LOOKUP_CODE are the headers,in excel output i want background color as blue.
Please do need full help,its urgent req.

Hello,
open the file in Excel and save it, just to ensure that Excel writes all the additional stuff it thinks is necessary.
Now change the background colour of the header and save the file again but with a different name.
Open both files in a text editor and look at the differences. That's what you need to change in your code.
Alternatively you can use packages like xml_spreadsheet or ExcelDocumentType, both write the same file format that you use in your code and you don't have to reinvent the wheel.

Top 5 best SOLID background colors for LCD?

What are the top 5 best SOLID background colors for LCD?
- Best for display ENDURANCE.
- Best for lower ENERGY consumption.
- Best for lower display TEMPERATURE.
Black? Dark blue? Dark green? Dark red? White?
Any Internet link supporting such claims?
Thanks.

1. In my experience, the white color wears out LCDs with time. For instance, the top main Finder menu of the Apple Cinema Displays shows white all the time with Mac OS X, and wears out with time (several years). You can see it when the Mac is booting and such area is shown darker. Actually, it has usually being recommended to use a full solid black background as the best screen saver to increase the LCD useful life.
There can be image burn-in with LCDs, but Apple says it can be fixed
<http://docs.info.apple.com/article.html?artnum=10639>
<http://docs.info.apple.com/article.html?artnum=88343>
(They recommend white for fixing it.)
2. So, if your argument is correct, it seems that solid white is the best color for lower energy consumption,
White won't reduce the energy consumption, but the display should run slightly cooler since it is radiation more light, instead of adsorbing it.
but solid black or a dark color could be better to increase LCD useful life.
It seems that it the black that burns-in (since they recommend a white screen to fix it), but not permanently.
3. Last but not least, the "Apple/System Preferences/Displays/Brightness" set at 50% or lower will also increase the LCD useful life (the less brightness, the better).
Don't forget to set display sleep in "Energy Save" system preference. Reduced brightness will make the backlight last longer, but won't affect burn-in Display sleep will help both.

Background color for column heading

Hi,
I have 5 columns in my report and I would like to have different background color for column headings. How can I do this in report templates?
I was looking at Column heading section-
<th class="t10ReportHeader"#ALIGNMENT# id="#COLUMN_HEADER_NAME#">#COLUMN_HEADER#</th>
How can I specify backgrund colors for all columns here?
Thanks in advance

G'day Karen,
Thanks for ur reply.
I have seen this note before, its not that the header colors have changed after latest SP was applied in our systems. Also the ABAP and JAVA stacks are in sync.
Scenario is that we are trying to set up a new Portal theme for Enterprise Reporting with some specific color codes (hex codes).
What i have observed is Characterstics Header background color is set up using the element "Background Color of Level 1 Column Heading ".
While the Background color for Key Figures header is using element "Background Color of Level 2 Column Heading ".
But the problem is element "Background Color of Level 2 Column Heading " is also used as the Background color for Standard Characterstics cell, so if we make it same the whole report of the same color, which we dont want.
Requirement is to get the same Background color for Header cells (both Char. and Key Figure headers).
Any further suggestions will be appreciated.
Thanks
CK

Defining a background color for a paragraph style

Hello and please excuse this very basic question, but I am completely stumped.
How do I simply define a background color for a paragraph style? I cannot use a table etc. because the styles are mapped during an XML conversion. Code lines should receive a gray background box to separate them from the text.
Also, is there a way to force line breaks whithin words for a specific style? The text, formated in Courier, should just fill the space with a fixed width per character and break wherever the line ends.

With some drawbacks it's doable using two paragraph tags.
The first tag, e.g. "Line" is empty (no text), and it has a reference page graphic that's just a rectangle filled 100% with color and set to have a percentage tint so that the text will "show through" it.
"Line" is also set to have a negative space below it, e.g. -12 points.
"Code" paratag has the actual code text in it, and it's set to have a negative space above, e.g. -12 points.
I've done projects where I have multiple Line paratags differing by the number of code lines needing to be shaded, e.g. Line1, Line2, Line3.
Unfortunately there isn't a way to automatically have the line expand to the correct depth of the Code paragraph, although I believe this would probably be something that could be done as a Framescript, to run through a document and create new "line" paratags of the correct depth depending on how many Code paragraphs or lines are in the following paratag.

UITableView: set different background colors for header and the table

I would like to set my background color for my UITableView to white and set my tableViewHeader backgroundColor to grayColor similar to the facebook app. When I bounce scroll my table so that you can see above the header, then currently it is white above the header view. I want that to be brown instead.
In the facebook app, above the headerview, it is a blue color and below the table is a white color. If i try and set the UITableView backgroundColor to brown, then the top will be brown, but so will the bottom. Additionally, all of the unset cells will have a brown background instead of white.
Any help with this?

Fixed..

Changing font and background color for all components

Hi,
This is my first time writing a GUI, and I'm pretty new to Swing and Java. I just recently switched from C++, and so far Java seems to be doing a nice job =)
Currently I have a gazilion components (textfields, labels, panels) and I'm wondering if there is a way to change their background/foreground colours without adding in setBackground/setForeground for every single component.
I've done some researching onto using Look and Feel, but there aren't any current ones that suits my needs. And everyone seems to mention that programming your own is pretty complicated.
My boss wants a slick white text on black background interface, so you can imagine that he's not very impressed with the current default greyish colours =)
Thank you for any help!
Cindy

Hi Cindy,
I'm not sure how effective a solution this will be, but you could try:UIManager.put("TextField.background", Color.BLACK); // Default text field background becomes blackThere are many more defaults you'd have to change and could probably achieve it more reliably and simply by creating or editing the properties file that controls the way the look and feel (even if it's the default) is implemented. Take a look at:
http://java.sun.com/j2se/1.4.2/docs/api/javax/swing/UIManager.htmlHope this is helpful

An applescript to change the background color for all finder windows

I'll start off by telling you what I am trying to achieve, then show you what I've tried.
I have a macbook with several HDD's attached. what I want is for each of those hdd to have a specific finder window background color. so no matter where I am in that hdd the background color will always be the same. so for instance if I set the background color of hdd 2 to blue then as long as I see a blue background I know that I'm within hdd 2.
I've tried setting up an applescript to do this but can only get it to change the open finder window, and none of the subfolders have their backgrounds changed.
here is what I have so far:
tell application "Finder"
tell the icon view options of the front Finder window
set the background color to {52942, 54484, 31097}
end tell
end tell
so how do I get this to apply to all subfolders without opening each one and running the script.
thanks in advance for any and all help with this

According to this article:
http://docs.info.apple.com/article.html?path=AppleScript/2.1/en/as2039.html
it seems that the various options can only be set while the window is open and in icon view.
Rather than manually opening the window of every single folder on the hard drive, it should be possible to write a script to open every folder in sequence, make sure it is in icon view, change its background, then close its window. I have never been any good at the "actions within actions" procedure needed for folders within folders, so maybe someone else with the necessary knowledge and experience might be able to assist in this regard. Such a script would probably take a few minutes to complete while it ran through "every folder of every folder", but it sure would be quicker to have the process automated than to do it by hand - computers are really good at repetitive tasks (as long as the instructions are accurate, of course!).
On the other hand, you might like to try the following:
open a few windows in icon view, choose Show View Options in the View menu (I'm in System 10.4), click the radio button All Windows, click the Color radio button under Background, then choose your color. It might achieve what you are trying to do.

How to retrieve default background color for JPanels or other containers?

Hi everybody, I've written a small class extending the default JTextArea, intended to provide the functionality of a small, descriptive item in JPanels.
import java.awt.*;
import javax.swing.*;
public class JInfoTextArea extends JTextArea{
     public JInfoTextArea(String text){
          super(text);
          setEditable(false);
          setFont(Font.decode("SansSerif"));
          setFocusable(false);
          setLineWrap(true);
          setWrapStyleWord(true);
//          setBackground(contentPane.getBackground());
          setAlignmentX(Component.LEFT_ALIGNMENT);
          setBorder(BorderFactory.createEmptyBorder(5,5,5,5));
}As you can see, there formerly used to be a third parameter, namely contentPane, which contained a reference to the parent Container in order to set the TextArea's background color appropriately for transparency.
Now, is there ANY way to retrieve the background color without either passing a dedicated parameter or doing something like
setBackground((new JPanel()).getBackground());Any help is greatly appreciated!
Yours, Stefanie

To answer your original question the UIManager contains properties of the various components. In case your interested the following program has a fancy GUI display of all the components:
