JSF selectOneChoice VS. Swing JComboBox
I have been so impressed with how clean it is using a JSF selectOneChoice with a selectItem and selectItems.
Using selectItem.itemValue and selectItem.itemLabel is intuitive, and fills a very common need.
I'm wondering if there is a similar type of component I can use with a JComboBox. It seems that a LOV binding needs a target data collection (and iterator); but I simply want a JComboBox to display labels and manage values, independent from an iterator.
Any suggestions are very much appreciated!!!

Well I would just like to update this thread as more than a year has passed since I began working on ADF BC & Faces. Coming from a SWING background, I've learned quite a lot about web development. For starters, it’s not as easy as "Drag and Drop" and RAD like some demo videos or evangelical pitches makes it out to be. There is a steep learning curve (about half year with daily interaction with JDeveloper) to get comfortable with this technology. Personally speaking, a firm understanding of page definition bindings was the hardest to grasp, but then again maybe I’m just a bit slow. Compared to SWING or desktop UI development, the richness of ADF Faces UI is limited to boundaries of the web browser.
<br>
However, within the last month, our team has made great strides in taking the first step in launching a ported module our internal system (legacy Oracle Forms used by hundreds of hospital employees). Our Dynamic JDBC authentication piece was the keystone for our first module (a modified version from Steve’s infamous “not yet documented samples”). Trying to take full advantage of this technology, we also have created reusable pages and BC components for CRUD operations.
<br>
There is still plenty of work to be done as we are now struggling with team development (difficult due to multiple file modifications within JDev’s). We are also eagerly awaiting several rich UI in the next release of ADF Faces. Overall, the light at the end of the tunnel is starting to appear and I hope the Oracle ADF team and everyone on this forum continues to actively contribute to the growth of this community.
<br>
Here are a couple of screen shots of our app if you are interested.

Swing JComboBox causes scrolling problems in applet
I have an applet with a JPanel that contains a JComboBox that lists font selections for a JTextPane in a JPanel below it. It contains about 12 items, of which only five are visible at a time. If I choose any of the first five and scroll the page on which the applet is running, there are no issues. However, if I scroll the page after scrolling down the list to the sixth item, regardless of whether or not I actually select it, it causes the graphics in the applet to corrupt. The JComboBox code is:
private JComboBox getFontFaceCB() {
String[] fontNames = new String[fontlist.length];
for (int i = 0; i < fontlist.length; i++){
fontNames[i] = fontlist.getFamily();
if (fontFaceCB == null) {
fontFaceCB = new JComboBox(fontNames);
fontFaceCB.setBackground(Color.white);
fontFaceCB.setPreferredSize(new Dimension(150, 30));
fontFaceCB.setMaximumRowCount(5);
fontFaceCB.setSelectedIndex(0);
fontFaceCB.addItemListener(new java.awt.event.ItemListener() {
public void itemStateChanged(java.awt.event.ItemEvent e) {
currentFont = fontlist[fontFaceCB.getSelectedIndex()];
StyleConstants.setFontFamily(textStyles, currentFont.getFamily());
jTextPane.setCharacterAttributes(textStyles, true);
viewWidget.repaint();
return fontFaceCB;
}This also happens if I set the default index to something that one must scroll down to reach (e.g. the sixth index) I was wondering if anyone else has come across this issue and has any idea as to how this may be resolved.
Also, if the window is minimized, resized, etc. the graphics also corrupt, but only after the aforementioned condition.
Edited by: BANZ111 on Dec 12, 2007 3:59 PMI have found the solution:
I had lightweight components intertwined with heavyweight ones, which, until now, I never regarded as being a possible source of problems. Apparently, when you scroll down a JComboBox, it changes from light to heavy weight? At any rate, I found this with a lot of other useful tips here:

Perhaps this can be of use to anyone else who gets a similar problem. -
JSF - selectOneChoice page variable problem
Hi,
I have bound my selectOneChoice component to my data control (view object), the "base data source" in the binding is a variable on the page definition (as described in the adf developers guide).
Everything works fine until I navigate away from and then back to this page, the variable value is lost and therefore so is my original selection in the selectOneChoice.
Is there a way to either persist the variable value or choose a "base data source" that has session scope? I don't want to choose a table as a base data source as the list is only for searching, not updating anything.
Thanks
MarkHi,
Your navigation cases are defined in adfc-config.xml (or any other task flow definition) as
<control-flow-rule>
<from-activity-id>main</from-activity-id>
<control-flow-case>
<from-outcome>login</from-outcome>
<to-activity-id>searchPage</to-activity-id>
</control-flow-case>
</control-flow-rule>while "main" is not the name of the page, but view id, it is also defined in adfc-config.xml
<view id="main">
<page>main.jspx</page>
</view>So, when you redirect to main.jspx your navigation just doesn't work because your navigation case is defined for "main", but authentication works (which you can test by typing some secured url directly in the browser).

JDev 11gTP4: ADF BC LOVs - JSF selectOneChoice sometimes empty
Hi JDev team
With apologies the following is a bit of a ramble rather than a good description of what the problem is within JDev 11gTP4. I'm a bit lost to know what the problem is or where to look next?!
I've created an ADF BC VO with attributes that derive 3 values from LOVs. All 3 correctly render in the Business Components Browser with a pop list.
I've also created 2 inputs forms, one standalone, the other called from an ADF Read-Only table page. Both inputs are based on exactly the same VO, created in exactly the same way from the data control pallete. This include selectOneChoice controls created for the LOVs.
The first page always shows the VO information correctly, and the corresponding selectOneChoice fields always have entries.
I'm getting very inconsistent results with the 2nd page called from the read-only table. Sometimes the selectOneChoice controls based on the ADF BC VO LOV fields are populated if called from a Create action, other times they're not.
I can't understand why I'm getting the inconsistent results to the point I don't know what to give you to find the problem. If I replace the selectOneChoice with an ADF LOV control, they always correctly show the data, so it would indicate the selectOneChoice controls are having issues.
I've also carefully compared the selectOneChoice attributes between the 2 inputForms, as well as the associated bindings, and they are the same.
The only other difference is the original inputForm is within the unbounded task flow, while the 2nd inputForm lies in a bounded (train) task flow. I can't think of a reason why this would make a difference though.
So at this point any help would be appeciated as I'm scratching my head to work out what's wrong here.
Thanks for your help in advance,
Cheers,
Chris Muir.Did you know this
Steve Muench quotes "Notice that in TP4 there is no longer an "ADF Create Form" and that we're encouraging you to create a create form using a method activity that declaratively invokes the create operation, then forwards to a page with a regular ADF Form on it. This is due to the numerous confusions that have always surrounded the ADF "invokeAction" now that we have a visual, declarative mechanism to model this type of initialization activity, we will prefer users adopting that. Also, notice that the page definition for the method activity has the new "SkipValidation" property set to true."
Andrejus made a create sample how to use a lov when the form is in create mode. If you don't do this you get validation errors and the lov is empty.
There is a thread in this forum and look at Andrejus blog for some create forms example

Java Swing: JComboBox setEditable(true)
How to limit the length of the text in Jcombobox with seteditable true to 255 characters.So that user can't enter text more then 255 characters.
You can get editor from the JComboBox. In the editor get a text filed used for edit. You can cast it to JTextField in the simplest case. Then add a DocumentFilter to the JTextFiled's document. Override the methods to check existing Document's length and ignore edits when limit is achieved.
public void insertString(FilterBypass fb, int offset, String string,
AttributeSet attr) throws BadLocationException {
fb.insertString(offset, string, attr);
public void replace(FilterBypass fb, int offset, int length, String text,
AttributeSet attrs) throws BadLocationException {
fb.replace(offset, length, text, attrs);

JavaFX equivalent of Swing JComboBox.KeySelectionManager for ChoiceBox?
Does ChoiceBox have any built-in key selection functionality as was provided by KeySelectionManager to JComboBox?
If so, could someone provide an example?
Else, anyone else think this would be worth a feature request? As a user, I really like being able to tab through choice boxes and just hit a key or two to make my selections as opposed to mousing and scrolling through all the items.I am also wondering a typical structure of application framework on java fx. Where will the screens be defined and created? How is an operational flow implemented? A simple login form with onSuccess, onError with sufficient redirections will be very helpful. I mean a crud skeleton based on common api of javafx will be a perfect guide.

JComboBox takes ages to load/refresh when tried to add more items.
Swing gurus ...
Here is the test app generated from VA3.5 concept is the
same - JComboBox takes long time to add data items to itself when added more items.
In this senario, I tried to load about 500 items into the combo box, takes about 2+ minutes to load. I have an app which needs to show about 1K items in the pick list ( ComboBox ) - which takes any where from 4 - 10 min - this is not acceptable - are there any ways we can load more items into combo box ?

2. You can download his code at http://www.reddfish.co.nz/freesoftware/PoliteComboBox.jar
3. You may want to reconsider your design, since a JComboBox with more than a few dozen elements is usually too hard for the user to use (see various postings in the long thread). -
Changing the size of a JComboBox
Greetings,
I am trying to build a mechanism to perform zooming on a JPanel with an arbitrary collection of components (including nested JPanels). I've tried a number of things with little success. The following is my most promising contraption. It can zoom labels, textfields, checkboxes, and buttons. However, for some reason, the combo box refuses to accept a changes to its size. I'm not sure why this is the case. Its font changes size appropriately.
Anyway, I'm running in JDK 1.4, and the following program lays out a palette of components. To change the size of the components, hit F1 to zoom in, and F2 to zoom out.

javax.swing.SwingUtilities.invokeLater(new Runnable()
public void run()
createAndShowGUI();component.setSize(transform(component.getSize()));First of all the above line is not needed. The LayoutManager will determine the bounds (size and location) of each component in the container based on the rules of the LayoutManager. The Flow Layout is the default layout manager for a panel and it simply uses the preferred size of the component as the size of the component.
So what happens is that when you change the font of the component you are changing the preferred size of the component.
So why doesn't the combo box work? Well I took a look at the preferred size calculation of the combo box (from the BasicComboBoxUI) and it actually caches the preferred size. The combo box uses a renderer, so the value is cached for performance one would assume. The method does recalculate the size when certain properties change. Note the isDisplaySizeDirty flag used in the code below:
else if (propertyName.equals("prototypeDisplayValue")) {
isMinimumSizeDirty = true;
isDisplaySizeDirty = true;
comboBox.revalidate();
else if (propertyName.equals("renderer")) {
isMinimumSizeDirty = true;
isDisplaySizeDirty = true;
comboBox.revalidate();
}It also handles a Font property change as well:
else if ( propertyName.equals( "font" ) ) {
listBox.setFont( comboBox.getFont() );
if ( editor != null ) {
editor.setFont( comboBox.getFont() );
isMinimumSizeDirty = true;
comboBox.validate();
}but notice that the isDisplaySizeDirty flag is missing. This would seem to be a bug (but I don't know why two flags are required).
Anyway, the following change to your code seems to work:
// component.setSize(transform(component.getSize()));
if (component instanceof JComponent)
((JComponent)component).updateUI();

Hi, i am working on a simple example to learn the Swing API. I have a small program that uses 6 different combo boxes. there should be 2 sets of 3 Combo boxes (day, month, year). My problem is that I cannot seem to get them to seperate. They always line up right next to each other. I posted some code below. sorry the tabbing is a bit screwy. if you paste it to an editor it will make more sense. anyways, i use 2 different jpanels, with a GridLayout of only one column (inserting Jpanels into a gridlayout of only 1 column), but still it aligns them together on the same line! i can't figure it out. any help will be appreciated. thanks
ps-you should be able to just cut and paste this code and compile if you want to see what i mean.

What is the best way to use Swing GUIs in an MVC design?
I have a question on how to build an application using swing frames for the UI, but using an MVC architecture. I've checked the rest of the forum, but not found an answer to my question that meets my needs.
My application at this stage presents a login screen to get the userid and password, or to allow the user to choose a new locale. If an Enter action is performed, the userid and password are checked against the DB. If not accepted, the screen is repainted with a "try-again" message. If the Cancel action is performed, the process stops. If a locale action is performed, the screen is repainted with different langauge labels. Once the login process is passed, a front screen (another swing frame) is presented.
Implementation: I am using a session object (Session, represents the user logging in) that calls the Login screen (LoginGUI, a Swing JFrame object with various components). Session uses setters in LoginGUI to set the labels, initial field entries etc, before enabling the screen. From this point, the user will do something with the LoginGUI screen - could be closing the window, entering a mix of userid and password, or maybe specifying a locale. Once the user has taken the action, if required, the session object can use getters to retrieve the userid and password values entered in the fields.
The crux of the problem is 1) how will Session know that an action has been taken on the LoginGUI, and 2) how to tell what action has been taken.
This could be solved by getting LoginGUI to call back to Session, however, I am trying to buid the application with a good separation of business, logic and presentation (i.e MVC, but not using any specific model). Therefore, I do not want LoginGUI to contain any program flow logic - that should all be contained in Session.
I am aware of two possible ways to do this:
1. Make LoginGUI synchronised, so that Session waits for LoginGUI to send a NotifyAll(). LoginGUI could hold a variable indicating what has happened which Session could interrogate.
2. Implement Window Listener on Session so that it gets informed of the Window Close action. For the other two actions I could use a PropertyChangeListener in Session, that is notified when some variable in LoginGUI is changed. This variable could contain the action performed.
Has anyone got any comments on the merits of these methods, or perhaps a better method? This technique seems fundamental to any application that interfaces with end-users, so I would like to find the best way.
Thanks in advance.Hi,
I tried to avoid putting in specific code as my question was more on design, and I wanted to save people having to trawl through specific code. And if I had any school assignments outstanding they would be about 20 years too late :-). I'm not sure computers more sophisticated than an abacus were around then...
Rather than putting the actual code (which is long and refers to other objects not relevant to the discussion), I have put together two demo classes to illustrate my query. Comments in the code indicate where I have left out non-relevant code.
Sessiondemo has the main class. When run, it creates an instance of LoginGUIdemo, containing a userid field, password field, a ComboBox (which would normally have a list of available locales), an Enter and a Cancel box.
When the Locale combo box is clicked, the LoginGUIdemo.userAction button is changed (using an ActionListener) and a property change is fired to Session (which could then perform some work). The same technique is used to detect Enter events (pressing return in password and userid, or clicking on Enter), and to detect Cancel events (clicking on the cancel button). Instead of putting in business code I have just put in System.out.printlns to print the userAction value.
With this structure, LoginGUIdemo has no business logic, but just alerts Sessiondemo (the class with the business logic).
Do you know any more elegant way to achieve this function? In my original post, I mentioned that I have also achieved this using thread synchronisation (Sessiondemo waits on LoginGUI to issue a NotifyAll() before it can retrieve the LoginGUI values). I can put together demo code if you would like. Can you post any other demo code to demonstrate a better technique?
Cheers,
Alan

JComboBox How to get input from JComboBox
Hi all.
I have a JComboBox called combobox.
User can choose one string out of 5 using this JComboBox.
Whenever the user press a button, I'd like to get an input through this combobox using actionListener.
How can I get input through JComboBox?
combobox.getValue() ???
I appreciate your help !http://java.sun.com/j2se/1.4.2/docs/api/javax/swing/JComboBox.html

JComboBox is not visible on JPanel
I have a class that extends JPanel. Within this class I have added several different components; JLabels, JTextFields, JButtons and a JComboBox.
All of the added components are visible and working except for the JComboBox. I can see the white background of the box and the popup and its list when I click on the area where the JComboBox is located, but I cannot see the selected text in the box. This seems strange since all the other components surrounding the JComboBox display correctly.
The background is set to white and the foreground is set to black. It has three options in the popup which are displayed using the foreground color, as it should. When I select an option from the popup, it seems to be working because the next time I display the popup, that selection is highlighted. But the selected text never shows in the box.
If I create a JComboBox in a JPanel, not an extended class, everything seems to work correctly. I can select from the popup and the selection appears in the box.
Could you please give me some suggestions as to how to make the selected text in the JComboBox visible?
Thanks
BobMy layout manager is set to null. I don't think that there is anything obscuring it because the backgroud is visible. The only thing that I can't see it the selected text and the combo box down arrow. I am using VisualCafe to generate this code.
