Visually express setEditable(false)

Hello,
On the GUI I write, if a user clicks an a radio button, a text field must not be editable anymore. It works with setEditable(false) but it has no graphical effect.
So Is there a way to put the text field and its associate label in gray?
I searched the API and various doc, but found nothing.
Thanks for help

SetEditable(false)

Hai..
I have a TextField called tf1
based on the setEditable(false) method i have to do some code like this
Is it possible to do like this ? or is there any other option to validate like this
I am new to java
please help me.
Thanks in advance
Yours
Rajesh
if (tf1==setEditable(false))
System.out.println("Textfield is not Editable");
else
System.out.println("Textfield is Editable");
}

Rajesh
Hi,
The setEditable() method does not return a boolean. setEditable()
is for setting a TextField editable.
tf1.setEditable(true);
isEditable() returns a boolean.
tf1.isEditable() returns true if tf1 is editable, flase if tf1 is not editable.

Inserting Icons in JTextPane with setEditable=false

Aloha!
I'm working on this for years now, but i haven't found an acceptable solution yet.
The problem: I have a JTextPane, where the user shall not be able to edit anything by clicking onto the JTextPane. So I have to setEditable=false. Now I want to insert an icon with insertIcon and therefore i have to setEditable = true. But for short time it's now possible for the user to click onto the screen and change the caretPosition, which must be prevented at all costs (because I'm working with the expected caretPosition of course)! This only happens when I try the brute force testing method, but it happens sometimes...
So can someone give me a better solution than:
setEditable = true;
insertIcon(blahblah);
setEditable = false;
Thanks a lot for your attention,
Holm

To use HTML, you must use javax.swing.text.html.HTMLDocument instead of StyledDocument,
Instead of StyleConstants, you must use javax.swing.text.html.HTML$Tag and javax.swing.text.html.HTML$Attribute.
And you can use an HTMLEditorKit instead of DefaultEditorKit.
this is an example of initialization:
javax.swing.text.html.HTMLEditorKit htmlEditorKit = new javax.swing.text.html.HTMLEditorKit();
javax.swing.text.html.HTMLDocument htmlDoc = (javax.swing.text.html.HTMLDocument)htmlEditorKit.createDefaultDocument();
yourJTextPane.setEditorKit(htmlEditorKit);
yourJTextPane.setDocument(htmlDoc);
yourJTextPane.setEditable(true);
yourJTextPane.setContentType("text/html");and you can use it by yourJTextPane.setText(HtmlCodeString)
HTMLDocument and HTMLEditorKit allow you main modifications.
thanks for duke dollars :)

Why doesn't calling setEditable(false) disable cursoring

I want to have JFormattedTextField format my date fields for me. It does a good job of it, so why wouldn't I?
I have a need to display a non-editable date for reference purposes. Unfortunately I discovered that the cursoring is still active when setEditable(false) is called. In order to prevent this, I have had to subclass DateFormatter in order to override getActions() to return null if I don't want incrementing. There are a number of problems with this:
1) setEditable on JFormattedTextField should have been enough. If I don't want it editable, then I don't want cursoring. I would have thought that was obvious.
2) Notwithstanding that, the correct method to override for incrementing is really getSupportsIncrement(), but this has no modifier, so is in the 'friendly' status, which means it can only be overridden in the package.
3) While I can override getActions, this signature leaves itself open to have other actions than "increment" and "decrement" returned . That is, it works now, but if sun adds more actions to the list of actions returned by getActions(), then my override is broken.
Is there a bug in there somewhere?
Thanks, Andrew

1) setEditable on JFormattedTextField should have
been enough. If I don't want it editable, then I
don't want cursoring. I would have thought that was
obvious.Nope not really. What if the user wants to copy some text using the keyboard?

WebTest - VS2013 - Extract Regular Expression - Required=False

I have an "Extract Regular Expression" that may or may not be able to extract a value. I set the property value of Required to False. The next block checks for the existence of that Context Parameter. If the Context Parameter is there, it does
some work, if the Context Parameter is not there, it skips the condition.
When I run my WebTest, it tells me that it passes the extraction rule but it never created the Context Parameter so the condition is skipped.
If I set Required=True, everything works as expected.
I remembered that there was a defect in VS2010 with the Required=False, so I added this Extraction Plug-In
[DisplayName("Extract Regular Expression Not Required")]
[Description("Extract text matching a regex and add it to the test context. If no match is found, do not fail webtest. This gets around a VSTS bug where 'Required' property of the Extract Regular Expression rule is not honored.")]
public class ExtractRegularExpressionNotRequired : ExtractRegularExpression
public override void Extract(object sender, ExtractionEventArgs e)
base.Extract(sender, e);
e.Success = true;
That too passes the regular expression but fails to create the Context Parameter.

By setting the Required parameter to False, I am expecting that a Context Parameter does not get created if the regular expression is not found and that is does get created if the regular expression is found.
So when I run my test, it tells me that the regular expression was found but my Context Parameter was not created.
When I created this webtest in VS2010, I found that there was a bug with the Extract Regular Expression when the Required property was False. This
thread showed the code for a custom Extraction rule to fix the problem. When I run this webtest in VS2013, both the built-in Extract Regular Expression and the custom Extract Regular Expression Not Required are not creating the Context Parameter if the
regex is found.
Try this yourself:
Create a webtest
Add "Extract Regular Expression"
Set the Regular expression to . (this will match any one character)
Set the Requiredto False
Set the Context Parameter Name to TEST
Run the webtest
Although the result from the extraction rule will be Passed, there is no Context Parameter TEST created.
If you create the custom Extract Regular Expression Not Required plugin, the same problem occurs.

hi,
i'm having troubles with MS Web Developper Express 2005 and RDB database ODBC driver 3102.

In search of a spesific style/expression! Maybe you know the name of it?

Hello fellow after-effects users,
I've been seaching for the name of a spesific style/visual expression/grade for a long time now and maybe some one here can help me out finding the common name for it. Here are the common elements:
* I think its trying to emulate a type of lens distortion.
* With sometimes green, red and/or blue superimpositions in the edges.
* Part of the image is blurred (in the edges of the image/vignette)
Here is a couple of not necessarily good examples. But make notice of the edges in both pictures, displacing and changing color:
Is there a common name for this effect?
Thanks.

Thank you ever so much for this!! Excactly what I was thinking about! Thank you and have a great new year.

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?

JTextField's - setting editable false, but without greying out the area?

Is this at all possible? Is there any other way to go about it? Or is the only way to make a textfeild un-edditable using the setEditable(false); command.. and sticking it with the grey area?
Sorry for the weird/dumb/annoying question..
Thanks anyway heh..

all i wanted was an answer and this dude just flames
me.I think your need to adjust your sensitivity downward by an order of magnitude. I didn't see anything in Joachim's response that remotely resembled a flame. He simply pointed out that your requested goal violates standard usability principles (rather politely, I might add). You referred to your own question in a more derogatory manner than any respondent.
Personally, I think his advice was very helpful. You shouldn't violate standard usability principles unless you're just deliberately trying to confuse your users, which is not something many of us would care to give advice on how to do...

SetEditable is not working with combobox

Hi,
I am working with table and using combo box in cell of table, in certain condition I have to make combo as editable and non editable.
I have written class which extends DefaultCellEditor
@Override
public Component getTableCellEditorComponent(JTable table, Object value, boolean flag, int row, int column)
comboBox.getModel()).setSelectedItem(value.toString());
comboBox.setEditable(true);
if i set comboBox.setEditable(true). cell become editable but i am not able to select item from combo..
when i do set comboBox.setEditable(false) cell become non editable and i can select value from combo but not able to enter any value.
i want both the operations. Editable cell in which user can enter any value and also can select value from combo.
Any Idea???? please share with me, this is blocking issue for me. Thanks in advance.

Cannot start Visual Studio 2013 Community edition

Windows 7 on a 64-bit PC...
Downloaded the installer vs_community.exe for Visual Studio 2013 with Update4 yesterday and ran it.
It took about 1 hour and 20 minutes. At the end the installer reported the web deployment function
could not be found/installed and that I could locate and install it myself later. It then told me to
restart the PC, which I did, but the Community edition had not been added to the start menu.
There are other Visual Studio versions on this PC:
Visual C# 2010 Express, Visual Express 2012, Visual Express 2013 and Visual Studio 2013 Ultimate
trial version. They can all be started from the menu and do not interfere with each other and they
installed without problems. There are 4 weeks evaluation time left for VS 2013 Ultimate and I want to
make use of that. VS Express can be shown the door if any of these might be blocking the
Community version.
I am puzzled by one more VS directory named Microsoft Visual Studio 2012 in Program Files(x86). This
contains many items added yesterday by the Community install including a directory named Community
with with two files licencse.htm and ThirdPartyNotices.txt. It also contains files and directories
added in November last year (ImportProjects, Preemptive Solutions...(don't remember what or if I was installing)) and some added in February this year when I installed VS Ultimate 2013 trial. So the VS 2012 directory contains a mix of items placed there by
VS 2013 installers.
Questions:
1. Could this mixed use be the cause of the Community version not being on the Start menu?
2. what can I do to fix this without losing the VS Ultimate trial?
3. Can Community version coexist with other VS versions?

I was installing by running vs_community.exe.
When I let the mouse hover over this file name information about the file pops up:
File Description: Microsoft Visual Studio 2013 Community with Update4
File version: 12.0.31101.0
Size: 1.18MB
I don't know, but I would guess this file installs the Community version.
I did not notice that the Community version will not run on the same computer as other VS 2013 versions. Is this in the documentation? And will the Community version be blocked by VS Express
versions too?
Now, as far as I understand to make the Community version work I will need to uninstall the VS Ultimate 2013 trial first. Will that remove the Ultimate files in the MS VS12.0 directory in Program Files (X86)? and will uninstalling Community remove its contribution?
I mentioned there are other files too in MS VS12.0, like SDK, Silverlight, WDExpress and Web. I don't remember installing any other program that might have put them there. Do I have to empty or remove MS VS12.0 before installing the community version? Then,
if there are some left-overs can I just delete MS VS12.0 manually?

Only send those records in report where expression is True

Hi,
I have created a formula with two formula variables on Dates. The expression in formula is Solved Date < Due Date.
This results in report showing 1 and 0 (1 where expression is true and 0 where expression is false)
But in BEx query designer is there any way to send only those records in report where expression is 1 (true)
Thanks
Ahmad

Hi Ahmad,
You can suppress zeros changing the query properties in rows/columns tab. If you select effect on rows, it doesn't show 0 values in the report. This will work if you have only that KF in your query, if there are any other KFs and you still don't want to show other rows then you can use conditions as seshu has mentioned.

JTextFeild.setEditable funny behaviour

Hey Guys I hope someone can help me as I'm completely stuck to whether this is a bug or whether I'm just missing something. Given the following code:
private void setComponentState( int state )
switch(state)
case 1:
btnSearch.setEnabled( true ); //JButton
btnReplace.setEnabled( false ); //JButton
txtBarcodeReplc.setEditable( false ); //JTextFeild
break;
case 2:
btnSearch.setEnabled( false ); //JButton
btnReplace.setEnabled( true ); //JButton
txtBarcodeReplc.setEditable( true ); //JTextFeild
break;
The problem I'm having is that everything works fine until the 3rd or sometimes the 4th time I call this method with a state=2 param. At this point the txtBarcodeReplc control refuses to enable itself. It changes color as it should and when the properties of the control are queried, the control thinks it's enabled, it's just that you cannot type anything or select inside the control. Interestingly enough, if I remove the calls to the other 2 jbutton controls so that the only thing this method does is reset my JTextFeild control, then it works perfectly fine. I'm curerntly using 1.3.1_09.
Hope someone has some idea's to how to solve this as I'm completely stumped

Apologies - the problem I was getting at is that it is unsafe to make calls on Swing components from any thread other than the Swing thread. This is unlikely when you are new to Java.
As for your problem - you can search the bug database. Does http://developer.java.sun.com/developer/bugParade/bugs/4680302.html look like your problem? If so then the latest version looks to be your only option, or try putting the text field in front (in tab order) of the buttons.
