Background color of textfield

Could some kind soul explain to me how I can set the background of a textfield to some color other than white in Interface Builder?
Here is a screenshot of my panel.
http://zach.in.tu-clausthal.de/tmp/textfield.png
The textfield is labeled "Image exclusion options" (in the screenshot it is selected).
No matter what I try in Interface Builder, I can't get the background to become some other color than white.
Does anyone have an idea? Do I really need to write several lines of code for that?
Thanks a lot in advance.
Best regards,
Gabriel.

Have you tried to select Draw background?
Yes, but IB always deselects it again.
You could also use NSTextFields setBackgroundColor Methode
ah, yes, but I was hoping to find a more elegant solution, because, you see, I don't need to access that field from my program at all (other than changing the background color ...)
Best regards,
Gabriel.

Applet-Panel, background color and size problem

I am writing an applet with simple form.
Form is having 3 rows and 2 cols (label and textfield). Each row I want to display in different color. So I created each row with 2 separate panel (one for label and one for text field - of which I set the backgroung color).
The total form is in one panel with grid layout (2 colmns).
My problems are
1)The space between label and text field (col width) can not be resized. I tried to use setSize but not giving any effect.
2)Another problem is when I am seting the background color, the textfield is also changing the color (textfield I want to white color only). This does not have any effect on Choice
3)The first label I wanted to use simple break but could not. I tried \n\t, \n, chr(13) + chr(10) etc but not getting any result so created separate panel.
My code goes here:
import java.awt.*;
import java.applet.*;
import java.awt.event.*;
public class test1 extends Applet{

I do not want to go into detail, but there are some hints you can follow.
I am talking about AWT, not swing, you should decide which one you will use and don't mix the two of them.
If you want to run your applet in current browsers without requiring the java plugin, you should be aware, that most browsers support old versions of java and many convenient methods and classes are missing :-(
So
You can change the size of a label by putting it in a panel ( labelPanel ), whose layout is set to FlowLayout. Then you put in labelPanel another empty panel ( emptyPanel ), whose layout is set to null, and you set the width of the empty panel to whatever you want ( this is the gap between the label and the next component ), an the height to the least nonsero number possible, i.e. 1. Well, you can add to the labelPanel more components, if you wish. So, when you want a gap, use an empty panel with a fixed size.
You cannot use line break in a label. You should place more labels in a panel instead. I am not sure if the direction of FlowLayout can be set to vertical, but very probably it can. If so, that is your solution. If not - see what other layout managers you have available, but make sure your choice belongs to java.awt ! BorderLayout allows you to use up to three labels (=> 3 lines). And if nothing fits your needs, ... write a layout manager.
Well, hope I could help.

Code for changing a TextField BackGround color?

Hello again!
I can´t find anywhere the code for changing the background color of a TextField, anyone knows?
I tried:
     TextField.border.fill.color.value = "255,255,255";      // doesn´t change bg color
     TextField.caption.font.fill.color.value = "255,255,255";     // doesn´t change bg color
     TextField.value.rectangle.fill.color.value = "153,153,153";      // doesn´t change bg color
Bur none of them works!

The script works fine..please show here..

Setting the background color of the selection when text selected (input TextField)

My input TextField has a black background. The problem is,
when some text is enter and then selected, the selection background
color remains black and the selected text remains white. Because of
this it's imposible to tell that the text has been selected. Is
there a way to change the selection background color, or do I
really have to write a custom textfield? :(

Yes, I do have an additional attribute called "identity" which is set to the original table where it came from. The problem is that I do not know how to check for it in my renderer. I will post my renderer code here
public class myTableRenderer extends DefaultTableCellRenderer{
public Component getTableCellRendererComponent( JTable table,Object value,boolean isSelected,boolean hasFocus,int row,int column) {
final Component component = super.getTableCellRendererComponent(table, value,isSelected,hasFocus, row, column);
if ( value != null ) {
if ( value instanceof String ) {
String val = value.toString();
if ( val.compareTo("DisplayKnown") == 0 ) {
component.setBackground(Color.CYAN);
else
component.setBackground(Color.LIGHT_GRAY);
} // end if value not null
return component;
} // end mytablerenderer
What happens here, is that only the column with the identity value "DisplayKnown" gets the color blue. I would like to color the whole row with that column value to be Blue.
Does this make sense??
Thanks,
npatel

Background color of non editable textfield

Dear all,
how can I set the background color with a css stylesheet of a textfield that is enabled but non editable "textfield.setEditable(false);"?
I can not find an example in the caspian.css stylesheet file.
Regards Tim

Use the -fx-background-color to change the background color of a TextField.
Whether the textfield is editable or not, makes no difference as to how this is done.
If you want the textfield background to change only when it is not editable, then you can use the :readonly css pseudoclass on the field as bouye suggests.
import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.*;
import javafx.scene.layout.VBox;
import javafx.stage.Stage;
public class TestCssStyles extends Application {
public static void main(String[] args) throws Exception { launch(); }
@Override public void start(final Stage stage) throws Exception {
    VBox root = new VBox();
    ToggleButton button = new ToggleButton("Toggle Editable");
    final TextField textField = new TextField("Frobozz");
    textField.getStyleClass().add("customtextfield");
    textField.editableProperty().bind(button.selectedProperty());
    root.getChildren().addAll(textField, button);
    Scene scene = new Scene(root);
    scene.getStylesheets().add(getClass().getResource("styletest.css").toExternalForm());
    stage.setScene(scene);
    stage.show();
/** styletest.css place in same dir as TestCssStyles.java and ensure build system copies it to the app compile output path */
.root {
-fx-padding: 10;
-fx-spacing: 5;
-fx-background-color: cornsilk;
.customtextfield:readonly {
-fx-background-color: coral;
}Edited by: jsmith on Aug 6, 2012 4:14 PM
Updated to demo use of a :readonly pseudoclass as per bouye's suggestion.

Change background color of a selected line of text in textfield

I have a list of items in a dynamic text field. When a line is clicked I would like to highlight it, or change the background color. Any ideas?

By default, the generated application uses the oracle skin family. This skin generates the buttons as images with rounded edges so you cannot change the background color. If you change the skin-family to "minimal" in the adf-faces-config.xml, then you can change the background color of the buttons by adding a property like this to the button template:
inlineStyle="background-color:red;"
However, a cleaner way to do this, is by creating a custom skin, so you do not have to modify the generator templates at all. See the following link for more info on ADF Faces skinning:
http://www.oracle.com/technology/products/jdev/101/howtos/adfskins/index.html
In addition, using the Check for Updates feature in JDeveloper, you can install additional sample skins.

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

Need to change the background color of a textview in offline PDF

Hi,
We are using the PDFDocument API in order to generate a PDF file which is eventually stored in a network folder. We were initially using the Webdynpro Interactive Form UI element, but digressed from that approach because of some architecture considerations.
I am able to do everything with the PDFDocument API, expect two things which are proving to be much tougher than I thought:
1) I have a textview in my .XDP template. The background color of this textview must change depending on the value that I display inside it. For example, if the value is between 1 and 20, the background color must be green, if the value is between 21 and 40, it must be yellow and so on...
I still have not found the method to specify the background color of a textview using the .XML data file.
2) Depending on a certain condition, I need to display 5 images in a table row instead of the usual 6. I have been able to do that by simply not providing the 6th image url, but I also need to resize the 5 such that they occupy the space that was initially used by 6 images.
Any ideas of how I can go about these requirements?
Thanks & regards,
Navneet Nair.
Edited by: Navneet Nair on Feb 19, 2009 10:09 AM

1) I added an invisible textfield inside my .XDP file and populated it with the color value that I want my main text field to display. (This color needs to be specified in the R,G,B format... for example... 128,0,0
2) Now in the 'Initialize' javascript event of my main text field, I included the following script:
this.resolveNode("<SubFormName>.<MainTextFieldName>").fillColor = this.resolveNode("<SubFormName>.<InvisibleTextFieldName>").rawValue;
Hope it helps!

JTextComponent - setEditable background color

I have a subclass of JTextField. I am doing manipulations of the background color (red when validation failed). When the program sets the text field to be not editable I want the default disabled background color (transparent?) to be displayed.
However, in some cases I am getting a background of white when it is disabled.
What is setEditable doing to change the background from white to grey? If I have the background color set to RED how do I change it so that grey will be shown?
Thanks,
John

I am trying to understand what setEditable does WRT the background color / transpanency. In the below code, when you press the button the first time, the background of the textfield becomes grey. If you press it again it becomes white. Is this because setEditable doesn't do anything if the field is already editable?

Htmltext background color

Hi.
My problem is: I need support for styling text background color inside htmlText property of a Text (or TextArea) control, for text that is marked up with html tags.
I am aware that Flex's htmltext only supports a subset of actual HTML tags:
the text is supported
the text is not supported
And this is a problem for me because I absolutely need to be able to change the background color for certain words in the text. I searched a lot for a solution with no success. The only thing I see that supports background color is the TextField object, but I have no clue how I would implement it in the same manner as the Text or TextArea control. Does anyone have any suggestions?
(compounded with this is that rather than use: the text, the text is marked up with the text tags, and these CSS IDs are being processed with a stylesheet object in actionscript. So ideally, the solution should also work with stylesheets, but I can work around it if I'm forced to resort to hardcoding in the HTML tags.)
Thanks for your attention.

Thanks, but I want to change the background color only in one
word, not all of the text.

Selectable mx:Label background color property

How can I change background color of selected text in my mx:Label when selectable=true. Default color is blue.
thanks in advance

Hi,
I think you should use something else for this use instead of Label.That will be better.
But if you want to do this with Label only then the solution is as below.
Create you own Label class which extends Label class of flex.And then use as I hv used it in my application.Below is the source
code for both.
CustomLabel.as
package
 import mx.controls.Label;
 public class CustomLabel extends Label
 public function CustomLabel()
 super();
 public function getTxt() : *
 return textField;
MainApplication
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"
 layout="vertical"
 xmlns:local="*">
 <mx:Script>
 <![CDATA[
 private function onCreationComplete():void
 customLabel.getTxt().background = true;
 customLabel.getTxt().backgroundColor = '0xFFFF00';
 ]]>
 </mx:Script>
 <local:CustomLabel id="customLabel" text="Hello world" selectable="true" creationComplete="onCreationComplete()"/>
</mx:Application>
Let me know if u hv any issue.

Background color changes when using AJAX

I'm using NetBeans and the plugin Project Dynamic Faces Ajax Components. Each time a radio button is selected a few textfields are hidden/shown.
But each time I press a radio button, my background color of my JSF page is changed (from blue) back to white.
Does anyone know how to disable this, or just how I can set the background of the page manualy in the java code.
I've tried this.setBackground(...); , but it doesn't work.

Hi. I currently use Canon, and i only see it in my RAW files. All camera firmware is up-to-date. I am running latest version of Aperture, but still running 10.6.8. I went through a bunch of old photos where there was a good red color of something and i was able to duplicate the problem each time. Where there was a large area of red, it was VERY noticable. Also, I used to shoot with Nikon and my NEF files do the same thing where there is a nice red. It seems to be an Aperature "thing."
What i find so curious, is that even if I make no adjustments to the Levels sliders, just checking the box alters the color, same with the Vignette brick. Also, I do color calibrate my monitor. thanks.

Flash CS5 How does one change background color in TextArea Component

I'm trying to change the background color of a TextArea Component. Does anyone know how to do this?
function processXML(e:Event):void {
var strTextBox:String;
myText.visible=true;
myText.setStyle("contentBackgroundColor", 0x000000); //Does not work..nor does myText.setStyle("backgroundColor",0x000000);
myXML = new XML(e.target.data);
strTextBox = "<a href='" + myXML.Branch[0].linkURL + "'> More Info...</a>";
myText.htmlText=strTextBox;

for that one you have use styles:
var newFormat:TextFormat = new TextFormat;
 newFormat.bold = true;
 newFormat.size = 18;
 newFormat.color = 0xFFFFFF; //I'm wanting white font on black background.
 //apply the format:
myText.setStyle("textFormat",newFormat);
 myText.visible=true;
myText.textField.background=true;
myText.textField.backgroundColor=0x000000;

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,
Nishanth.C

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.
