How to persist state of JCheckBox component (Swing)?

I've been hunting all over the place for a simple way to save the state of a JCheckBox item, so that the next time the program is run the state is restored. My window sizes are restored, and tab selections are remembered, but how do I persist the check box state?
I haven't been able to find any information on this ... can anyone help?
Cheers,

It would have been handy to mention that the app. already uses the [Swing Application Framework (JSR 296)|https://appframework.dev.java.net/]. The blurb of the framework has a series of feature, one of which is.
- Support for managing and loading resources, like strings, formatted messages, images, colors, fonts, and other types common to desktop applications.
So it seems the functionality you want is there, but I have not delved into this API yet, so am unable to advise further, but note that is has a dedicated forum.

How can I make non-inspectable component properties persist from design to runtime?

Hey,
I have two components (lets call them A and B) which have normal inspectable properties (e.g. NAME and AGE) which allow you to enter values via the component inspector. When I type the value for NAME in component B (via the component inspector) I communicate via a singleton class and store this value in a NON INSPECTABLE property located in component A.
When I run the movie, I want to access this non inspectable property within component A; however, it is always null - the value will not persist from design time to runtime. I check that the value is set at design time by tracing the A's non inspectable property once component B has set it - and it does indeed work, so I know component B has managed to set the correct value in A.
Basically, what I need to know is, how do you persist properties of a component from design to runtime, without having to make properties inspectable and having to manually type property values via the component inspector?
Many thanks

Hi
I would think <componentInstanceOfB>.NAME would give you the current value of NAME in the component B. This can be accessed by any component (say A), when A knows the instance name of the component on the stage. So probably all you need to know is tell the instanceOfA the name of instace of B and then instanceOfA can access the value as <instanceOfB>.NAME.
Hope this helps.
Cheers

How to read checked or unchecked of JCheckBox in swing?

how to read JCheckBox in swing,i m not able to do that, every time its take true value only.

In the future Swing related questions should be posted into the Swing forum.
What method are you calling now? I don't think you are calling the correct method.

How to save content of a whole swing page

Hi everyone ..
can any of u tell me ,how to save contents of a java swing page in a single file with all components viz . textfield,textarea,JTable,JPanel etc .. with their respective formatting ie.e Font,Color etc ..
Plz let me know it soon .. its very urgent ..
Can I save it as Screenshot or Jpeg Image .. or how to go about it .

Sure: see below!
WARNING: this code will not compile as is because it uses some other classes from my personal code library (FileUtil & StringUtil). The particular methods of those classes which are used below are trivial methods that anyone can write, which is is why I have not posted them as well. So, to get the code below to compile, you can
a) write your own versions of these classes or
b) simply add the necessary methods to this class or
c) simply comment out their usage (in the case of StringUtil, which is just used for arg checking)
But if you still want me to post them, then I can post the relevant fragments of those classes.

* Class which supports taking screen shots of the entire desktop, AWT Components, or Swing JComponents.
* This functionality is implemented in a series of <code>take</code> methods, each of which returns a BufferedImage.
* This class also offers convenience <code>write</code> methods for storing BufferedImages to files.
* 
* The images taken by this class should be the precise images seen on the screen.
* However, the images written to files may deviate from the originals.
* One obvious cause is limitations of the chosen file format (especially with lossy formats like jpeg).
* A subtle issue can occur, however, even when using lossless formats like png:
* if the file is subsequently opened by another application,
* that application may rescale the image, which can often cause visible artifacts.
* <blockquote>
* To see this last problem on Windows XP,
* call {@link #take()} which returns an image of the entire desktop and write it to a file,
* and then open the file with XP's default graphics file viewer ("Windows Picture And Fax Viewer").
* This program shrinks the desktop image in order to fit it inside the program's window,
* and rescaling artifacts are readily seen, especially if the desktop image has any kind of text in it.
* If "Windows Picture And Fax Viewer" instead cropped the image or had a scroll pane, then this should not happen.
* </blockquote>

* Acknowledgement: this class was inspired by the program
* <a href="http://www.discoverteenergy.com/files/ScreenImage.java">ScreenImage</a>.
* Differences from the above program:
* <ol>
* <li>this class uses {@link BufferedImage#TYPE_INT_ARGB} instead of {@link BufferedImage#TYPE_INT_RGB} in order to preserve alpha</li>
* <li>this class's {@link #formatNameDefault default image file format} is PNG instead of JPEG</li>
* <li>this class's <code>take</code> methods simply take snapshots and never have the side effect of writing image files</li>
* <li>this class added a version of <code>take</code> which can get a snapshot of a region of a Component</li>
* <li>
* when taking a snapshot of a region of a Component or JComponent,
* the Rectangle that specifies the region always has coordinates relative to the origin of the item
* </li>

* It might appear that this class is multithread safe
* because it is immutable (both its immediate state, as well as the deep state of its fields).
* However, typical Java gui code is not multithread safe, in particular, once a component has been realized
* it should only be accessed by the event dispatch thread
* (see <a href="http://java.sun.com/developer/JDCTechTips/2003/tt1208.html#1">Multithreading In Swing</a>
* and <a href="http://java.sun.com/developer/JDCTechTips/2004/tt0611.html#1">More Multithreading In Swing</a>).
* So, in order to enforce that requirement, all methods of this class which deal with components
* require the calling thread to be the event dispatch thread.
* See the javadocs of each method for its thread requirements.

Please help me........for writing enititybean with persistent state

I am new person in ejb,actually i am working on one module where ejb deployment
is there in websphere 4.0 with oracle database ,where as my module form is just retrieving
data from database for user but doest not create it.So according to sun specification
entity bean should have create() and findByPrimaryKey() methods but in my case i have to
just retrieve data i.e findByAllData(). Here i am passing a parameter institute_id,
which is not a primarykey in this table which retrives records under that particular institute id
but in my case entitybean doesn't initialize to any particular
primary id since create() method is not existing in my bean so container doesn't
have any account of primary key.So now it won't store the data in persistent
state in the container because of none of the create() method for primarykey.But
we want to store the data in entity bean in the appliaction server in the persistent

How to make a global scope component to be thread safe?

One of my global component preserves states in its member variables, I am afraid that it's might messed up in multi-threading conditions, so how to make a nucleus global component to be thread safe?
Edited by: user13344577 on Jul 14, 2011 9:45 AM

Hi,
Just to help integrate Shaik's and my own seemingly contradictory replies:
If the member variables in your global component actually need to be globally available, so that multiple threads/sessions need to seem the same data, then you need to use synchronization or some scheme to make this data thread-safe when updating it. If the member variables are non-global data and are simply for convenience of having data available for multiple method calls or something like that, then you should do as I said (don't use synchronization) and use one of my suggestions to avoid this.
I have seen customers frequently do what I replied about and store non-global data in a global component, and Shaik simply interpreted what "user13344577" is trying to do differently. Clarification is needed to know which of our answers better applies.
Thanks.

How to persist TextInput text values?

Can anyone provide a brief explanation of how to persist text
values?
Description:
Stuff written into a TextInput field does not persist when
moving
to another frame, and back again.
Example:
Frame 1: Put a TextInput component on the stage.
Frame 1: Put a "forward" button on the stage.
Frame 9: Put a "back" button on the stage.
Frame 1 actionScript:
this.btnForward.onRelease = function() {
gotoAndStop(9);
Frame 9 actionScript:
this.btnBack.onRelease = function() {
gotoAndStop(1);
Play it.
Write something in the TextInput.
Click the forward button. (this takes it to Frame 9)
Click the back button. (this takes it back to Frame 1)
>> The TextInput field is blank.
Hoping someone can help,
Thanks,
John

read?
Details:
Frame 1:
1) I declare a variable in Frame 1, and initialize it to
null:
"var myStr:String = "";"
That seems reasonable (thoug technically you set it to an
empty string and not to null, but the empty string is better in
this case)

2) I save the value in the btnForward.OnRelease function:
"myStr = Ti.text;"
when using the button this way you would have to use
"this._parent.myStr = this._parent.Ti.text";
as the scope in buttons behaves different if you put the
action directliy on the button (flash 5 way) or if you do it your
way.
quote:
3) I add a line to set the TextInput text: "Ti.text = myStr;"
4) When I Play it, Ti is empty. I type in words, and click
forward (moving to Frame 9). Then I click back (moving to Frame 1).
Ti shows "undefined".
Thanks for your patience,
John
I hope that helps.

How to use annotation with GUI in swing

hi,
i am new to annotation. I know how to use this with classes, methods and java elements. I am developing a tool in applet to post comment on my notepad, but unable to find that how to use this with GUI of swing. I have gone through most of forums and tutorials but got no idea. Anyone could give me little idea.
Thanks

>
i need to use the applet mousedown function in swing..>There is no such class as 'applet' in the JRE, Swing has an upper case 1st letter, functions in Java are generally referred to as methods, and there is no 'mousedown' method in the JRE.
OTOH a Swing JApplet inherits the mouseDown method from Component, and it was deprecated in Java 1.1. The documentation (JavaDocs) provides instructions on what to use instead.
>
is there any way to use it or any other alternative is available for this?
if can provide me a sample code.>If can provide me cash. Short of that, you might actually need to do some research/coding of your own.
As an aside. What does any of this have to do with Java 2D?

Change the Production state of Software Component in SLD

Hello,
I cannot see the list of software component to add in Dev Configuration because the Production State of software component is in Planned state and to appear in the list it should be in Devlopment state.
How do I change the state. When I login to SLD i dont see the edit mode to change it.
Thanks
PS: I did not realize there is separate NWDI forum. I also asked the same question in Web Dynpro forum.

Hi,
if the question is about, why the custom developed software is not visible in "CMS - Landscape Configurator - Track Data tab" when pressing the button "Add SC...", then please answer:
Did you trigger "Update CMS" after creating the software in SLD? You can do it in the CMS webui - Landscape Config - Domain Data tab.
Best Regards,
Ervin (http://wiki.sdn.sap.com/wiki/display/TechTSG/%28NWDI%29Home)

Change state with MenuBar component

It's pretty easy to change the state with a button. Example:
click="currentState='AboutScreen'"
But when I try to do this on the MenuBar component, I'm not
having any luck. When I click on the item (let's say Help ->
About), nothing happens. My code is:
click="currentState='menu.student.create_profile'"
I also tried,
itemClick="currentState='menu.student.create_profile'"
No luck.. anyone know how to change states based off items
clicked from the MenuBar?

This should get you started:

If you go to the partial trigger property of any of your page component you can open the edit partial trigger browser.
There you can find the components of your template and their ids

Orchestration exception:Exception occurred when persisting state to the database because of special character ' ' in HL7 message.

In some scenarios HL7 message is coming with special character ‘’ and HL7 dis-assembler escaping this character with “”. But while sending out (pass thru pipeline but orchestration trying to persist here at last sendshape.) from orchestration
this message failing with the error “Exception occurred when persisting state to the database.”
As per the analysis , Orchestration is unable to convert to xml document from a
XLANGMessage because of this special character. We have tried to call custom .net class with following code and its failing here as well (I think orchestration also trying to do same way and failing with the message and failing with same error.).
public void ProcessRequest(XLANGMessage reqMessage)
XmlDocument xmlDocument = (XmlDocument)reqMessage[0].RetrieveAs(typeof(XmlDocument)); It is failing here with the error
“ ', hexadecimal value 0x10, is an invalid character. Line 1, position 1865. “
Note : Please find the special character in the attachment circled in red color.

Hi ,
Please find the xml and the screenshot.

Vishwas Sahu

Hi Vishwa,
             The control would be something like this for navigation in Get_p_xxx method u mention as link and u mention a event name which gets triggered on the click of this hyperlink. So your GET_P_XXX method would have the following code:
CASE iv_property.
    WHEN if_bsp_wd_model_setter_getter=>fp_fieldtype.
      rv_value = cl_bsp_dlc_view_descriptor=>field_type_event_link.
    WHEN if_bsp_wd_model_setter_getter=>fp_onclick.
      rv_value = 'EXAMPLE'.
Now you have to create a method as EH_ONEXAMPLE at your IMPL class and within which you would give an outbound plug method. Within the outbound plug the target data would be filled in the collection and window outbound plug would be triggered.
This is a huge topic and i have just mentioned you basic things.

Bharathy.

How to get the list of component?

 How to get the list of component through java API in Adobe CQ5?

There are probably more than a few ways, but here is a little component .jsp code that uses the jcr query api to pull out all the components and list them on a page. If I know CQ, there might be a way to ask for a list of components another way though, maybe through another API, or possibly a .json url, I might remember reading something about that, somewhere, lol, but this at least gets you the list in a somewhat simple way.
Code Example:
<%@include file="/apps/psul/components/global.jsp"%>
<%@ page import="javax.jcr.*,
 javax.jcr.query.*"
%>
<%
 // Login to create an anonymous session on the default workspace
 Session session = resourceResolver.adaptTo(Session.class);
 //Declare a query for all the components in the system
 String SQL = "select * from cq:Component";
//side note: if you want just the components in your site area, then make the query more like below...
// SQL = "select * from cq:Component where jcr:path like '/apps/yoursitename/%'";
 QueryManager qm = session.getWorkspace().getQueryManager();
 Query query = qm.createQuery(SQL, Query.SQL);
 QueryResult result = query.execute();
 NodeIterator nodes = result.getNodes();
 while (nodes.hasNext()) {
 Node node = (Node)nodes.next();
 %>
 <%=node.getName() %> (<%=node.getPath() %>)
<% } %>
