(JTree)Full node caption is not visible

Hello everyone,
I am a novice swing developer.
I have generated JTree by implementing TreeModel interface.
I show node caption by overriding toString() metod of node object.
Now on valueForPathChanged event i make changes in child node so node caption changes accordingly.
But full node captions are not displayes instaead it shows partial name followed by ...
Kindly suggest appropriate solution.

This sounds backwards to me! I would expect you to fire the 'valueForPathChanged' event when you update the value associated with a node.

  • Node Handles not visible.

    Hi i have a tree table based on the swing example for TreeTable 2. My nodes for the data does get added and i do expand the tree in the tree table by calling the method:
    tree.scrollPathToVisible(new TreePath(child.getPath()));
    But the root handles for the root or the child nodes are not displayed in the TreeTable. It could be because i'm not using fireTreeNodesInserted(TreeModelEvent e). But i don't know what each parameter in the event stands for. I would really appreciate your help if youcan tell me why the node handles are not visible.

    Thanks for posting your own solution!
    It was exactly the same problem I had for about a day - driving me mad it was.

  • Value attribute not visible in runtime collection

    Hi,
    I have created some 2-3 value attributes (display only) in a standard model node for BTDOCFLOW (which also contains some display only fields). Put in the logic in their Getter methods and fields are getting displayed in UI with the values.
    Now, my requirement is to display this table view (Assignment block) in default sorting based upon one value attribute and one model node attribute. But the problem here is, I am unable to find value node attribute at runtime in BTDOCFLOW collection at DO_PREPARE_OUTPUT. (Even display only standard context node attributes, which are not part of model node structure are not visible)
    I have re-defined method GET_TABLE_LINE_SAMPLE with the value attributes, resulting in enhanced rv_sample line, but still the value attribute is not visible at runtime in the collection.
    Can someone pl. tell me, how can I display my value attributes in collection along with model node attributes, so that I can do default sorting based upon one custom and one model node attribute.
    Thanks,

    Hi,
    Whne you define value attributes within the model attribute then the node becomes mixed instead of either value node or model node.
    So you need to access the mixed node and then should access model attributes and value attributes separately.
    Get your collection into a normal entity then assign the entity to mixed node
    DATA: lr_mixed TYPE REF TO cl_bsp_wd_mixed_node ,
                current TYPE REF TO if_bol_bo_property_access,
                 lr_current TYPE REF TO cl_crm_bol_entity.
         current ?= me->typed_context->entity name->collection_wrapper->get_current( ).
          lr_mixed ?= current..
          lr_current ?= lr_mixed->if_bsp_wd_ext_property_access~get_model_node( ).

  • JTree - dashed lines and + and - icons not visible

    Hi,
    I implemented a TreeCellRenderer for my JTree:
    public java.awt.Component getTreeCellRendererComponent(javax.swing.JTree tree, Object value, boolean sel, boolean expanded, boolean leaf, int row, boolean hasFocus)
    Object userObject = ((DefaultMutableTreeNode)value).getUserObject();
    if (userObject instanceof Struct)
    this.setLeafIcon(this.iconStructClosed);
    this.setClosedIcon(this.iconStructClosed);
    this.setOpenIcon(this.iconStructOpen);
    else if (((DefaultMutableTreeNode)value).isRoot())
    this.setLeafIcon(iconEmptyClosed);
    this.setClosedIcon(iconEmptyClosed);
    this.setOpenIcon(iconEmptyOpen);
    /*else
    this.setLeafIcon(iconDatatypeClosed);
    this.setClosedIcon(iconDatatypeClosed);
    this.setOpenIcon(iconDatatypeOpen);
    return super.getTreeCellRendererComponent(tree, value, sel, expanded, leaf, row, hasFocus);
    ...the icons of the nodes are displayed correctly, but the dashed lines to visualize the level of a node and the + and - icons for collapsed or not collapsed nodes are not visible. I am using Windows LAF. What's wrong ?

    Please provide following information also:
    1) Are you using the default images?
    2) What is the Image URI?
    3) Snapshot of the Structure window, property inspector window?
    4) Are you using any switcher?

  • Full Screen is not visible

    Hi Experts,
    When i execute any web dynpro application(e.g Leave Approval) in browser(IE6), the screen is not visible fully that's why i can't click on submit button in order to approve the req.
    work around for this issue is F11. by pressing F11 full screen comes up but I need permanent Solution. Kindly help me.
    I appreciate any suggestions.
    Regards
    Manish

    Hi Manish
    Are you running the application directly from the wd or you have created the iview for that application?
    If you have created an iview for your application, there might b the reason that you forgot to set the open page property as full page. If this is the case, do it.
    If you are running your application from wd itself, and not able to see the complete view - try this
    1. try to run in other IE versions. But, tell you something, 6 is the best to run all the applications.
    2. check the component used by you in the application & there sizes. Sometimes, problem comes that you outerframe size is less as compared to inner. This will result in the same situation.
    Just try this and tell me if something worked out for you. Thanks.

  • Menu bar is not visible, but neither is Full Screen mode button. How do I fix this?

    While I am in Firefox, it appears that I am in Full Screen mode, as my Menu Bar is missing while in the application, but when I looked up how to troubleshoot, it told me to click on the Full Screen mode button (with diagonal arrows) but it is not visible anywhere in my browser. How else can I get out of Full Screen mode? Thank you!

    On Mac you can use: command+Shift+F

  • Node not visible in the JTreeTable

    Hi i am using the example provided at www.java.sun.com for TreeTable. I have a tree table and when i add new nodes the data is visible in the table but the nodes are not visible. I don't know how to resolve this problem. Below is my code where i'm adding new data.
    private void addNewNode(MyNode _root) {
    NodeInfo info = new NodeInfo();
    info.order= "Pending";
    info.qty = "200";
    info.price = "20,000";
    MyNode node = new MyNode(info);
    _root.add(node);               
    tree.expandPath(new TreePath(_root.getPath()));

    It's hard to say without seeing the code for TreeTable. But they probably have something like an addNode mothod for the TreeTableNode which will take care of all the updates for you. If you want to do it youself, you will probably have to get the data Model (tree.getModel()???)behind the TreeTable and use one of the fire... methods on it like fireRowChanged(???) or fireTableChanged(???). I would suspect Sun would do it this way.

  • Lables fully not visible in the Tree node

    Hi friends,
    Some text in the tree node were not visible fully.
    example : instead of documentation, it just displays doc...
    instead of Library, it just displays lib....
    And the problem doesn't appear continuously. Sometime the text is fully visible and some time it doesn't.
    If I expand the tree the text is fully visible again. I couldn't reproduce the issue continuously. I tried tree.repaint(), tree.validate(), tree.invalidate(), tree.revaidate(). but it didn't work.
    Anybody can suggest what would be the exact problem?
    Thanks in advance.

  • SAP RM: How can I create a Node when the node is not visible for the user

    Hi,
    Product: SAP records Management for Public Sector
    Version: 7.00
    is it possible to create a instance node when the model not is not visible for the active user?
    I looked in the CL_SRM_XML_REC_MODEL but every methode I used gave me no results with the special user.
    Regards and thanks for every beginning
    Fanninger Thomas

    Hi,
    here an example.
    When I use the method CL_SRM_XML_REC_INSTANCE->IF_SRM_XML_POID~GET_ALL( POID_TAB COUNT_USER_REST COUNT_POID_AUTH ).
    When I used the user with no right for viewing the invisible nodes I get no elements in the tabelle POID_TAB and 38 in the value COUNT_USER_REST.
    So did any one know a solution you can I create a nodes and change the restriction for the new node with the normal user?

  • Hierarchy Node Variable is not displaying full list of Hierarchy

    Hi,
    I loaded Hierarchy  to an info object using flat file.
    When i created a test reports and settings to display of MAster Data of Char and executed the report
    The output displays full list of Hierarchy
    Now to have a User Entry on Hierarchy ...created a Hierarchy Node variable and executed the value help of Hierarchy Node variable is not displaying fill list of Hierarchy ...its only displaying first 15 entries in Hierarchy.
    I changed the settings of variable...etc but couldn't get the Hierarchy full list in User entry selection
    How can i fix it...
    Thanks in advance

    If anyone has the same problem, I think I found the reason when transported to production.
    BW7.3 (at least) can not show the hierarchy nodes if there is no transactional data loaded.
    So do your hierarchies only after the data has been loaded..

  • DataSource is saved, but not visible in BW under the node NODESNOTCONNECTED

    Does anyone know a work around for this?
    Thank you.

    Hi,
    you are missing Application Component Hierarchy in your BW System which is stored in tables called RODSAPPL and RODSAPPLT (for the texts).
    First try to replicate the DataSources/Component Hierarchy from the Source System.
    Goto RSA1 -> Source Systems -> Replicate DataSources
    Goto DataSources again and try to activate.
    Take also a look:
