Bound Property Reference ?

hi all.
can any one tell me where i can find reference on bound property of each swing component?
i would like to know what bound properties each component has and what each property means.
i don't have money so i would appreciate free reference.
thanks in advance.

reason for wanting such a loose hanging property is
Bug or feature: TextBox can't handle null text
textBox can't cope with null text (which is a valid value in the domain) so need to adapt somehow withouth being interested in the adapter at all, so keeping it around as a field is ... polluting code

Hi Andrew,
With an EAV mapping most (I would even say all) jpa annotations are ignored. In this case (afaics) the xsd element has
minOccurs=1 (the default). This means that for ecore (and Teneo) it is a mandatory feature which must have a value. The
EAVSingleEAttributeValueHolder.mandatoryValue field is used to enforce required/mandatory constraints.
So in this case it can be solved by adding minOccurs="0" to the xsd element.

What is a JavaBeans bound property ?

What is a JavaBeans bound property ?
I don't understand this concept.
It seems it have to do with the Look and Feel, to bound the model to the component or something like that?

Let me change the question:
SwingConstants.CENTER works. Why?
Doesn't "import javax.swing.*" include SwingConstants?importing in Java is not like importing in C. Import javax.swing does not include the contents of the classes in those packages to the contents of the current class. It signals that the ClassLoader should look in that package to find a specific class(es) that will be used in this class. So by doing
import javax.swing.SwingConstants;
or any other import, you are not gaining the ability to use that class's variables (or constants) or members as if they were part of your class. You are just telling the runtime environment where to look for the class.
A quick look through the Java Tutorial should do some good in understanding this. Or an explanation from someone smarter than I.

Hi
yes, I had the same issue and I found a solution.
You need to request a patch for BUG 9212862 (already corrected in WLS 10.3.3) and do the follwing:
javax.xml.ws.BindingProvider provider = (javax.xml.ws.BindingProvider)port;
java.util.Map context = provider.getRequestContext();
context.put(weblogic.wsee.jaxrpc.WLStub.POLICY_COMPATIBILITY_PREFERENCE, weblogic.wsee.jaxrpc.WLStub.POLICY_COMPATIBILITY_MSFT);
This will cause the SecurityMessageArchitect class of WLS to not send the SecurityTokenReference in the Soap security header.
Please note that is evidently a non-comformity to the specs of microsoft:
Please give a look at
http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-soap-message-security-1.0.pdf (8.3 Signing Tokens)
and also at:
http://www.oasis-open.org/committees/download.php/16768/wss-v1.1-spec-os-SAMLTokenProfile.pdf
(3.4 Identifying and Referencing Security Tokens)
A SAML key identifier reference MUST be used for all (local and remote) references to SAML 1.1
assertions. [...]
All conformant implementations MUST be able to process SAML assertion references occurring in a
<wsse:Security> header or in a header element other than a signature to acquire the corresponding
assertion. A conformant implementation MUST be able to process any such reference independent of the
confirmation method of the referenced assertion.
It follows that the .NET 3.5 is a non conformat implementation: I would gladly know which is the position of Microsoft on that.

Order Item Specification Editor Property References Tab - Documentation Bug

Hi,
I am trying to create a cartridge with Order Transformation Manager entities. However I'm stuck with Property References tab of order item specification in 7.2.4 DS. I checked the documentation but its not completed it seems.
http://docs.oracle.com/cd/E49311_01/doc.724/e41610/dscom_oi_edt_propref.htm#DSCOM142
Check the above URL under "Dynamic Parameter Property"

I notified the appropriate writer, who replied that the Dynamic Parameter Property description should read: "Select the order item property in which dynamic parameters for the order item should be stored."
The fix will be included in the help for the next major release.

Bound property problem

Can the property binding in javabeans work if the bean doesnt have a "PropertyChange" method implemented in it. If yes, then how ?
Similarly, how does a bean handle the case of multiple bound properties. This question arises because, there is only one "propertyChange" method in a bean and it recieves a PropertyChangeEvent parameter. In case of multiple bound properties how does a bean know which properties propertychange event has been fired?

But this means that the property change listener has to be aware of the names of all the properties that it can bind, which is a severe limitation ! This is because , if I want to make a bean which has a property color , then it would be very difficult to make the bean so generic so that it can be bound to any bean containing a property representing a color. Unless and Until I know the name of the property of the source bean, I cannot make use of the propertyChange method of the destination bean to handle the change in property.
The problem comes when a bean has multiple properties . In that case, in it's property change method, it has to filter based on the names which are not known until runtime.

Where can i find the method and property reference?

hello,
i am now writing ActivX for C++ and LabView ( as container). However, I cant find the detail description of all properties and methods of the exported class from LabView. Can you suggest me some reference of it? thanks so much of it!

Hello
Open up The LV Help and goto the search tab to look for ActiveX Server Virtual. You should find a page called ActiveX Server Virtual Instrument Class Properties and Methods. This lists all the methods and properties of the Virtual Instrument object.

My front panel blanks while I use the panel bounds property

When I execute the PanelBounds property of the front panel, the panel seems to blank for a brief moment allowing me to see the desktop and then reappears. I am wondering how to prevent this behavior or approach the problem in a different way. Any ideas?

Here is a demo version that demonstrates my issue.
Open the dummy user interface (UI.vi) and the main program (Main.vi). Run Main.vi. See how the UI flashes when changing areas of interest. I can see the desktop during the transition since the front panel blanks.
Tip: Close the front panel with Alt-F4 since it will be full screen.

CS5 won't display php object property references correctly.

All,
   I have some code that I know works, its a script I got from here:
http://www.evolt.org/node/60384
A short summary of the problem is illustrated through this code:
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>Untitled Document</title>
</head>
<body>
<?
class Session{
     var $name = 'blah';
$sesh = new Session;
echo '<p>'.$sesh->name.'</p>';
?>
</body>
</html>
It seems that the page when viewed locally should display
blah
but instead I get
name.'
'; ?>
In fact, any time I use the '->' php feature in Dreamweaver this sort of thing happens.
I have xampp installed, created a site and local server for the particular project, and have used CS5 for numerous other projects without problems (I know the procedure for running php and mysql locally), although I have never used classes and the -> feature until now.
When I upload the script to my live webserver, it works fine. But, I would like to get to the bottom of this problem so that I can test more effectively on my own computer. I believe the problem lies either in Apache's or Dreamweaver's interpretation of '->'.
Any help would be greatly appreciated.
Thanks,
   Zach

You're missing the "php" in the opening bracket - should be <?php

Coding Practice for Bound Property Names

I think this simply an issue over coding practices, but if I am right then all the tutorials and documentation on how to write Beans are promoting poor coding practices. Speicifcally, it bugs me that String literals are always used in all the code I see. As in the following code:
class MyBean {
   public void setValue(value newValue) {
      beansupport.firePropertyChange("value", oldValue, value);
}the practice that I have starting using is:
class MyBean {
    public static final String propertyValue = "value";
   public void setValue(value newValue) {
      beansupport.firePropertyChange(propertyValue, oldValue, value);
}This way, a PropertyChangeListener can refererence MyBean.propertyValue instead of using the literal "value" -- eliminating the chance for error and also there don't have to be multiple literals floating around using up space. Is there any reason this isn't commonly accepted practice or did I miss something?

Strings appearing in source code can be reduced to a constant, like an enum. So it is likely that the code with strings is actually faster, as the value is known before compilation. It is easier to read. Keep in mind that strings get interned every now and then and thus get reduced to this equivalency:
public method blah( "value", some stuff )...
public method nah(*){ do stuff; let x = "value"; more stuff with "zoiks!" }
ends up like
key k1 = "value"
key k2 = "zoiks!"
what the jvm sees;
public method blah( key1, some stuff )...
public method nah(*){ do stuff; let x = key1; more stuff with key2 }
The string values get "inlined" and can be checked during compilation, allowing for many optimisations not otherwise possible.
Hope that helps a little.

Get Specific References for all Controls

Using slightly modified code from here, I am generating an array of all control references on my main front panel which is then passed through to a number of subVIs. Although this functionality does work, it would be preferable to get specific references to the controls (for example, Boolean RefNum instead of Control RefNum).
Getting these specific references seems possible using To More Specific Class and Class Specifier constants. However, data storage becomes an issue because I can no longer use arrays (as they are a different data type). I am not sure if there is another way to pass this data on. I have experimented casting the RefNums to Variants, but to get the data from the variant, I have to know what RefNum type I am expecting which sort of defeats the purpose of doing this in the first place.
A secondary problem is keeping the names of the references. The Control RefNums do not have names associated with them nor do I know how to assign names to them. I've again tried using variants and using the OpenG Set Data Name function, but this crashes LabVIEW without any indication of why.
I've attached a version of my code that tries assign names using OpenG Set Data Name and build a variant array. To run it, simple add the VI as a subVI to a VI that has some boolean controls on the Front Panel. Apologies for the rough state of the code - I'm still in the process of figuring out how to make it work so things are a bit messy.

Get Specific Control Refs.vi ‏28 KB

I don't know if you'll get much better. There is really no way I know of to have some fully flexible way of building named clusters of references based on any given front panel set you feed to it.
I tend to do things the manual way (as there are also a bunch of references to front panel elements I wouldn't need). I would do all the bundling work in a subVI.
I'm attaching a zip file that contains the key VI's (unless I missed something) on the first project where I really tried to abstract out the reference building. The files are LV9.
On my main VI, I have the subVI called Build UI References early in the VI during an initialization phase. I pass the reference to the main VI into that subVI that builds all the references. I worked it as a master cluster that contains elements that are arrays of references of related controls. It uses another subVI called Get References and Label Names that I created to help find controls. I still need to use More Specific Class to get the property references, but I don that only once at the beginning. I then pass that cluster wire out and to anywhere in my VI that would need access to the references for front panel elements.
I use arrays of strings to supply the names I need to build and bundle the references. This lets me ignore controls I don't care about. The disadvantages to my system is that if I change the name of any control, I need to update the name within this subVI. And if I want to add any controls, not only do I need to add the label names for the searching functions, I also need to update my typedef cluster (and you definitely want this to be a typedef) to add a spot to store the new reference.
I hope this gives you some ideas. It worked for me and I will likely use the scheme on another project (or even rewrite past projects using this scheme.) If there are any ideas for improvements, I'd be happy to hear them.

How do you set the size / bounds of a waveform chart at run time?

I have a plot area that I would like to fill with as many waveform charts as the user specifies (at run time). The "bounds" property is read only and I haven't noticed an additional "size" property for a waveform chart as there is for a button. Is there a way to set the size of a waveform chart at run time, and if not, why not? (Labview 6.1)

Look at it a little more carefully, I suspect that your assumption is only half wrong. The property does only resize the plot area--LV resizes the frame to fit the resized plot on it's own.
You'll need to bear this in mind when you're figuring-out what size to set the property to.

How to know the "minimum panel size" property

I want to know the "Minimum Panel Size" specified in the "VI properties" by programming. It's very important to get this information, because my panel size changes over the execution and I need the minimum panel size available. I can’t use the panel bound property because it return me the actual size of the panel.
Any idea?
Thanks for your help.
Solved!
Go to Solution.

There is no property to directly return the minimum panel size that you set.
You can however trick it into giving it to you. Since you can't use the "Panel Bounds" property to make a window smaller than it's set minimum, You can try to set it to 0,0 size, then read the size and subtract the left from right and top from bottom to get the size. The panel will actually resize to the minimum, but will return an error if you try to go below that.
The attached VI shows this working. I only tried this 7.1, so if you have an earlier version, let me know and I'll save it back.

Bound Properties and Listeners

First i will explain what I'm trying to do: I have two different panels and I'm trying to get the JTextFields to communicate in such a way that whatever i type in one JTextField will show up in the JTextField of the other panel (not necessarily in real-time). I think my problem is more in the design of my program than anything else.
First I have my interface (will i need to extend EventListener?)
public interface BookI {
     public abstract void setName(String name);
}I have a Book class (the bean) which implements the book interface. "name" is a bound property.
public class Book implements BookI {
     private PropertyChangeSupport propertyChangeSupport = new PropertyChangeSupport(this);
     public void addPropertyChangeListener(PropertyChangeListener l) {
     propertyChangeSupport.addPropertyChangeListener(l);
     public void removePropertyChangeListener(PropertyChangeListener l) {
     propertyChangeSupport.removePropertyChangeListener(l);
     public void setName(String name) {
               String oldName = this.name;
               this.name = name;
               propertyChangeSupport.firePropertyChange("name",oldName,name);
}Then i have my user interface which catches the event.
public class BookUI extends JPanel {
     private JTextField nameText = new JTextField(10);
     static class MyNameChangeListener implements PropertyChangeListener {
         public void propertyChange(PropertyChangeEvent evnt) {
            if (evnt.getPropertyName().equals("name")) {
                            // this is where i try to set the new value
                            // the new value will be coming from another JTextField in another panel
                        // nameText.setText(evnt.getNewValue()));
     public BookUI() {
                 // I tried adding the listener something like this
                 // addPropertyChangeListener(new MyNameChangeListener());
     public void setName(String name) {
          nameText.setText(name);
}I have another panel similar to BookUI that has a JTextField and whatever changes i make to it should affect BookUI, the listener.
For example:
public class AnotherBookUI extends JPanel {
     private JTextField nameText = new JTextField(10);
     public AnotherBookUI() {
}Any ideas would help.

I believe I should be able to do this with Listers.
I think I would need to add listeners to my interface like so:
public interface BookI {
     public abstract void setName(String name);
     public void addPropertyChangeListener(PropertyChangeListener l);
     public void removePropertyChangeListener(PropertyChangeListener l);
}I created a new interface so my classes can communicate:
public interface EntityPaneI {
     void displayObject(Object entity);
}This is the UI that should receive the changes
public class BookUI extends JPanel implements EntityPanel {
     private BookI currentBook;
     private JTextField nameText = new JTextField(10);
     class MyNameChangeListener implements PropertyChangeListener {
         public void propertyChange(PropertyChangeEvent evnt) {
            if (evnt.getPropertyName().equals("name")) {
// not sure if this will work
                             String newStringValue = evnt.getNewValue().toString();
                            nameText.setText(newStringValue);
     public BookUI() {
// not sure if the will work
              nameText.addPropertyChangeListener(new MyNameChangeListener());
     public void setName(String name) {
          nameText.setText(name);
     public void displayObject(Object e) {
          setCurrentBook((BookI)e);
          setName(currentBook.getName());
}The above UI should listen to changes from another UI like this one (same thing basically):
public class AnotherUI extends JPanel implements EntityPanel {
     private BookI currentBook;
     private JTextField nameText = new JTextField(10);
     public AnotherUI() {
     public void setName(String name) {
          nameText.setText(name);
     public void displayObject(Object e) {
          setCurrentBook((BookI)e);
          setName(currentBook.getName());
}
