Swing JTree in JDeveloper

HI all,
I'm trying to create a JTree using JDeveloper and when the JTree is displayed it displays color, food, sports etc as its elements. Does anyone knows how to change these default values using JDeveloper.
Thanks
Rajesh

Try editing the TreeModel from the GUI editor if you need static values. If you are using ADF and want to bind the values to something in a database, then you should just bind the JTree with the GUI editor wizards. For other dynamic data, you will need to provide a custom TreeModel. More information on JTrees can be found at [1].
Hope this helps

    There is no automatic way to do this in JDeveloper. I know there are some Oracle Partners offering forms to java conversion, I don't know how much of their tools are automated and done with JDeveloper. With JDeveloper+ADF you basically rewriting the Forms application from scratch (and using ADF is helpful during this process).

    Hi,
    we do have plans for supporting NetBeans' Matisse in a future version of JDeveloper. Until then JDeveloper expects the layout definition to be part of the jbinit() method. However, adding the required libraries to the JDeveloper project you should be able to at least use the code editor for further developing the project

  • Jtree  in jdeveloper

    hello
    i am user of oracle 10g jdeveloper using jclient/swing in my product. i am using oracle 9i as a backend.
    As you might be aware of that in jdeveloper in order to build a jtree we have ->
    select a view , select a display attribute , select an accessor
    question->
    how to select two display attribute corresponding to one view .
    please do help me if you can.
    thank you

    Aparna,
    we are going to release a new ADF component demo that will cover this scenario for the tree component. Not sure how long it will take to load the sample to OTN, guess that this will be done in between teh next two weeks.

  • How to open to a set child node using the swing jtree bound to adf views

    Hi All, I have an oracle adf jclient application that implements a jtree based on view objects derived from my database tables. Everything is working except that when a child table is updated and I re executequery() on my viewobject that is bound to the jtree, the tree collapses. Is there any way to programatically navigate the tree to open and select the new child node/object?

  • Can't see imported swing code in jDeveloper visual designer

    Hi,
    I developed a small swing utility program in either Eclipse or NetBeans (it's been a while, and i forgot which one I used last). I'm now trying to use jDeveloper for all java development, but ran into this problem: when I look at my JFrame in the visual designer, I see the outer frame object, but none of the nested controls inside (buttons, tabbed panes, etc.). I can see all the code and I see the objects in Structure panel. I know when I migrated between Eclipse and NetBeans I had to make some changes to my code to make it work with the visual designers there. I'm pretty shocked to have the same problem in jDeveloper. Any ideas?
    Thanks,
    Dennis

    That is happening because you must follow some requirements
    if you want to import code and use the visual designer tool:
    - It must be a Java file.
    - It must be free from syntax errors.
    - It must contain a public class (the file name must be the same as the name of the
    public class).
    - It must follow JDeveloper coding conventions:
    * All UI controls are declared as class members or as local variables within jbInit().
    * All UI property settings done in jbInit(). This is necessary in order for the
    JDeveloper UI Editor and Property Inspector to reflect the settings.
    * All property settings set as expressions involve only member UI controls or
    static values.
    - It must have a default constructor.
    Any file that meets the above requirements can be visually designed using the UI Editor and the Property Inspector. You can also visually design a non-UI class.
    Hope this helps !

  • JAVA Swing - JTree

    Hi,
    I would like to know how implementing a horizontal tree in JAVA. I know
    the JTree class, but by default, these one creates only some vertical trees.
    Is it possible with JTree? Or another class?
    Thanks for your help.
    Motorenshi

    that a pretty vague problem to try and diagnose. My advise, use a debugger and watch the code execute to understand why it is behaving the way that it is. Is the problem predictable, or does it vcary from time to time. Variance might indicate threading issues. Sounds like you are in for CS hell to me.

    I'm getting a problem if a file/directoy is added to the file system, after my Applet is loaded. Actually, i have used DefaultTreeModel's reload() method and calling it SwingUtilities.invokeLater() using Thread, but its not working.
    Plz help me out.

  • Future of Swing Developement in JDeveloper 11g  ?

    The Swing part (in the preview) still is unfortunately far behind NetBeans (have a look at Version 6 M9 Matisse with JPA beans binding, not as good as ADF but...) and others, are there any plans to integrate Matisse and/or JSR 296 in the production release? Or is JSF the only technology on the gui layer that is pushed by Oracle in the future?
    What's with javaFX (F3)??
    best regards
    Charly

    Charly,
    this first 11g technology preview reflects the bulk of the features in the UI clients areas that will be available in the initial 11.1.1.0.0 release when it goes production. I agree that the JDK 6.0 GroupLayout layout manager made popular by NetBean's Project "Matisse" GUI builder is a very interesting one from a developer productivity point of view -- it dupliates some of the productive layout "guides" ideas I believe first seen in the Visual Studio 2005 Windows Forms designer. We have our eye on supporting it in a subsequent 11g release. However, that support unfortunately won't make the initial production release of 11g. We also support the JSR 296 and are following it for including support in a future release, too. Regarding JavaFX (F3), just as you are this week, we're getting our first real look at what it means. I assume if it becomes a popular option it will be something to support for future JDev releases as well. We have significant 2/3-tier Swing data binding features that should fit in nicely with JavaFX, but it's honestly too early to say what our plans are there.
    Of course we continue full support of our existing ADF Swing features (including the productive JGoodies FormLayout support we introduced in 10.1.3). We've added a few new interesting ADF Swing components as noted in the 11g "New Features" document, too, as well as rewritten the critically important ADF Business Components Browser testing tool using ADF Swing during this release as a showcase and testbed of ADF Swing functionality.
    While from the new features list you can see we've improved features in many major feature area, in the "UI Clients" area much of the UI-related features in this initial 11g release are out of necessity centered around the significant declarative application development requirements put to us by our Oracle Fusion Applications teams (who are building front-ends using JSF Rich Client). We have thousands of internal apps developers, many of whom have already begun using early builds of our 11g technology platform for development of their next generation of Oracle Fusion Applications.
    In this initial 11g release cycle, given these multitudinous requirements presented to us by our combined Oracle, Peoplesoft, Siebel, and JDEdwards teams, there was reduced bandwidth available for making significant enhancements to our other kinds of UI clients that we continue to support like Struts, ADF Swing, or Mobile clients.
    This definitely does not mean there are not enhancements queued up, waiting to be implemented in future releases in these areas. Only that the initial 11g release doesn't have an "explosion" of new features in those areas.

  • Swing JTree class problems... (feature request)...

    Hello,
    I'd like to be able to change Nodes positions (at least two children inside the same parent node without having to remove/add them [which looses expanded/selected states]).

  • How to connect ms access in swing application  JDeveloper

    hi guys,
    How do I do to connect MSAccess database in a swing application in JDeveloper?

    Just wondering, you asked how to connect to MS Access from a swing app being developed on JDev...
    Are you using ADF ? Or just using JDev to develop a plain vanilla java swing app ?
    If not using ADF :
    You could try the JDBC ODBC bridge. http://download.oracle.com/javase/6/docs/technotes/guides/jdbc/bridge.html
    Might be better than half baked JDBC type 4 drivers for Access.
    If using ADF, I'm assuming you have an ADF model project and an ADF swing project. If you can manage to use the JDBC-ODBC bridge, you should be able to configure a DataSource for your model project as javax.sql.DataSource and javax.sql.ConnectionPoolDataSource are now supported though the bridge.
    Please keep in mind the warnings on http://download.oracle.com/javase/6/docs/technotes/guides/jdbc/bridge.html, especially the limited scalability and performance.
