Hi,
Is there a "elegant" way to make blink a treeview node?
I am thinking to use a timer with the collection of nodes that I want to make the blink effect, and update the icon ...

Hi,
You can develop your custom control for this purpose. The logic you mentioned was correct. Here is a sample control that I developed by the logic you mentioned.
public class BlinkingTreeView : TreeView
private Timer t = new Timer();
private List<TreeNode> blinkingNodes = new List<TreeNode>();
public BlinkingTreeView()
t.Interval = 1000;
t.Tick += new EventHandler(t_Tick);
bool isNodeBlinked = false;
void t_Tick(object sender, EventArgs e)
foreach (TreeNode tn in blinkingNodes)
if (isNodeBlinked)
//update Icon
tn.Text = tn.Text.Substring(0, tn.Text.Length - 1);//to test
isNodeBlinked = false;
else
//update Icon
tn.Text = tn.Text + "*";//to test
isNodeBlinked = true;
public void AddBlinkNode(TreeNode n)
blinkingNodes.Add(n);
public void RemoveBlinkNode(TreeNode n)
blinkingNodes.Remove(n);
public void ClearBlinkNodes()
blinkingNodes.Clear();
public List<TreeNode> BlinkingNodes
get { return blinkingNodes; }
public int BlinkInterval
get { return t.Interval; }
set { t.Interval = value; }
public void StartBlinking()
isNodeBlinked = false;
t.Enabled = true;
public void StopBlinking()
t.Enabled = false;
just show me how to use BlinkingTreeView class. i will have tree view which will have few node and few nodes may have few child nodes. now how to achieve by this class BlinkingTreeView and show me how to blink few specific node not all. thanks

better to come with code. first populate tree view with some dummy node this way
Root
       Child1
                Child1-sub1
                Child1-sub2
       Child2
                Child2-sub1
                Child2-sub2
now blink Child1-sub2 & Child2-sub1. please come with code. thanks

  • How to expand a tree at a specific node/item?

    Hi,
    we have a tree and the nodes/items were binded to context with this code
    lo_nd_nvccmp = wd_context->get_child_node( name = wd_this->wdctx_nvccmp ).
    lo_nd_tree = lo_nd_nvccmp->get_child_node( name = wd_this->wdctx_tree ).
    lo_el_tree = lo_nd_tree->bind_structure( new_item = ls_tree set_initial_elements = abap_false ).
    We want that the tree is expanded at a specific node/item?
    The structure has the field is_expanded of type WDY_BOOLEAN. I think that if the field of the right structure is 'X' then the tree should expanded. How can we find the right structure in the context and change this field to 'X'?
    Code is appreciated.
    Thanks, regards

    Oh, apparently if you try that call right after you create
    the Tree, it will throw a null reference exception. That might
    count as a bug in the flex api...
    If you create a Tree, and give it's dataProvider some xml
    data, and then add it to the stage (addChild), and then you call
    expandItem or expandChildrenOf() right after, you will get a null
    object exception. You have to wait... for something. I don't know
    what.
    I even tried calling _tree.invalidateList() before the
    expandItem, but it will still throw the error...
    I wonder what the Tree needs to wait for? Is this a bug for
    Adobe to fix?

  • How to have a tree view for value node..

    Hi all,
    I need to display a tree view for a value node in web ui  just like a model node, for a custom view in a pop up. Please guide me  how to do this or let me know the process steps.
    Thanks in advance.

    Hi All,
    while debugging I found that in class CL_BSP_WD_CONTEXT_NODE_TREE , the method GET_T_TABLE the below code is not triigerring for the child node attributes ( to trigger the get method of attribute for value node).
    this call method is not triggering at all only for first coulmn its triggering ..
      LV_TN ?= ME->NODE_MAPPER->GET_NODE_OBJECT( <LINE>-NODE_KEY ).
        CONCATENATE 'GET_' COMPONENT INTO LV_METHOD.
        TRY.
            CALL METHOD LV_TN->(LV_METHOD)
              EXPORTING
                ATTRIBUTE_PATH = ''
              RECEIVING
                VALUE          = VALUE.
          CATCH CX_ROOT INTO LV_ERROR.
    I created the GETTER method inthe class CN01 and CN02. But those methods are not triggered in CALL METHOD LV_TN->(LV_METHOD). Even that class CN02 is having the  same methods. Those methods are already Implemented. May I know what was the reason Why those methods are not triggered ( getter method ). With out that Method data will not display in the Tree view. Can anybody tell me the reason why it is not happenning?
    .Please find the below .HTM code  as well.
    <chtmlb:configTree
                          actionsMaxInRow       = "5"
                       id             = "Table1"
                       nodeTable      = "<%= ZTREEVIEW->node_tab %>"
                       table          = "//ZTREEVIEW/Table"
                       noFrame        = "FALSE"
                       personalizable = "TRUE"
                       onCollapseNode = "NODECOLLAPSE"
                       selectionMode  = "MULTILINEEDIT"
                       onExpandNode   = "NODEEXPAND"
                       onRowSelection = "select" />
    Only one column was triggered another column did not get any value becasue of the above method call fail.. We are not restricted anywhere to display one column value in the output.   Even in Debugging I checked that LV_METHOD  is having the method name. CN02 class is also having the  same method, But it is not going into the method. It is coming out side. What could be  the reason I could not able to understnad.
    Please provide me some pointers on the issue....

  • How to address message to the specific node of the ESB cluster

    Hi!
    We are running ESB on two node active-active cluster configuration. We use custom adapter to communicate with customer legacy system over Socket connection. The point is, that we need to transfer large amount of data from our database into customer system using one open socket connection. Because of memory limitation we had to split data into multiple messages in ESB. This socket connection can be open from any of the active cluster node, but ones it's open all messages must be send within the node which had open the connection.So, the messages should not arrive into another node. The question: How is it possible to address (route) ESB messages into specific node of the cluster?
    Thanks in advance.

    Thank you for your reply. It is very useful for me.  But i can't give conditional operator in that operator. It is showing error.
    My Test cases
    A[0]+A[1]>150

    If those are your exact statements, then they don't make sense in a formula node.  You have to use them in an if-statement or some other type of control logic.  This mimics text-based programming languages such as C... See here for instructions on formula node syntax: http://zone.ni.com/reference/en-XX/help/371361G-01​/lvhowto/formula_node_syntax/
    For instance, you COULD say something like:
    **In this example, let A[0] == x, A[1] == y, A[31] == z**
    if(x+y>150)
    /* do something if this is true */
    else if(z-50 < 100)
    /* do something else */
    EDIT: 
    It should also be noted that Variable Names MUST be lowercase!! I just discovered this
    EDIT2:
    I stand corrected.  After trying to create an example and digging through the LabVIEW Help, I stumbled across this:
    Differences between the Parser in the Mathematics VIs and the Formula Node
    The parser in the Mathematics VIs supports all elements that Formula Nodes support with the following exceptions:
    Variables—Only a, a0, ..., a9, ... z, z0, ..., z9, are valid.
    Logical, conditional, inequality, equality—?:,, &&, !=, ==, <, >, <=, and >= are not valid.
    Functions—atan2, max, min, mod, pow, rem, and sizeOfDim are not valid. You can use these functions in a Formula Node or use their corresponding LabVIEW functions.
    So it DOES NOT seem like Eval Formula Node can do conditionals like you want.  I would just implement them using a LabVIEW based algorithm after all.  Trying to out smart the formula nodes to avoid simple LabVIEW code is just too much of a hassle

  • How to make Tree View sort-able-"ICCMP_INBOX/InboxItems"

    Dear Expert,
    Does anyone knows how to activate sort functionality in Tree View.

    Hi,
    I "solved"  my problem with  using some not-used   fields  based on the  Configuration Key.  Not nice but it works.
    I think it should normaly  work with adding fields on  structure   crmst_inbox_resultlist   but this is  **.   In other screens that solution works good.
    see   ->  get_table_line_sample
    TYPES: BEGIN OF line,
    INCLUDE TYPE crmst_inbox_resultlist.
                node_name        TYPE string,
    Anyway thanks for your reply.

  • ADF Tree Traversal from one node to its leafs

    Hello,
    after a titanic effort I have been able to add a checkbox next to each node of an adf tree table.
    This checkbox is based on an "helper" entity attribute (not mapped to a column table on the database).
    My next huge problem is to perform an automatic selection of all the checkboxes next to the nodes under the currently selected one.
    For example, if the user checks a checkbox in the second level, then all the checkboxes next to the nodes under that, belonging to level three and four must be checked.
    If this helps, in my case there are at most four levels.
    Up until now I can get all the information from the currently checked node, but I fail to navigate the hierarchy under it for the automatic checking. I think that one problem is to navigate all the rows in the (only) VO the tree is based on. For example, since the tree is not expanded at the beginning, if I iterate on the VO retrieved from the current selected node at the top level, I can't see any rows corresponding to any children. Maybe I just miss something.
    I have followed this example from Frank Nimphius, which only gets the current selected nodes, as I said, but no more. Maybe this is a good starting point, but I need to advance somehow.

    Hi,
    here is a sample of how to search in trees, which actually shows how to traverse trees from a specific node
    http://www.oracle.com/technetwork/developer-tools/adf/learnmore/61search-in-rendered-trees-177577.pdf
    Given you have a transient attribute defined, each node (and instance of JUCtrHierNode --> getRow will give you access to the attribute for read/access). Note that because the checkbox is stamped in the context of the tree, upon selecting a parent node, you need to refresh the tree to show the selection state change

  • How to scroll to a specific node in the webdynpro tree

    Hi all,
    I'm developing an application where I need to load and expand a tree upon some action in another view.
    Loading the children, expanding nodes and setting a new lead selection (with cl_wd_dynamic_tool=>set_tree_lead_selection) all works fine.
    But I did not find a way to scroll the tree, so that the node is in the currently visible area of the tree. Is there a way to do this?
    Thanks for your answers!
    Best regards,

    Tree is a particular structure, you need to realize a recursive function, specially if the tree with is a recursive TreeNode.
    this is a quickly answer, i did this in java.
    The idea is the same everywhere, this is an ABAP-LIKE solution, understand and translate in a good ABAP source.
    FUNCTION FindNode(TypeNode tree_node, TypeNode node_to_find ).
    IF ( tree_node.ELEMENT_ID EQ node_to_find.ELEMENT_ID ).
    """""""    do what you wanna do  """""
    ELSE.
      n = tree_node.GET_NUMBERS_OF_CHILDS;
      """"""""" RECURSION
      FOR i = 0 TO n.
        child_node = tree_node.GET_CHILD(i).
        CALLFUNCTION FindNode(child_node, node_to_find ).
      ENDFOR.
    ENDIF.
    ENDFUNCTION.

  • BSP Tree View - how to create checkboxes on each node?

    Hello all,
    On my (non-MVC) BSP page I'd like to have a tree in which each node has a checkbox that the use can select, e.g. node 1.1: X, node 1.2: space; node 1.3: X
    It doesn't seem like the standard <htmlb:tree> can do this. Is there any quick way I can achieve this functionality?
    Any suggestions/code samples will be appreciated.

  • Tree view control - populating speed - over 100 nodes

    I have a few questions about a tree view control:
    1. If you put more than approximately 100 nodes in a tree, it populates too slow. There is no change if you try with query or record group. I figured that the populating of the record group makes all problems, but there is no chance to enlarge the array siye of the record group. Developer 6 has some built-ins which can do that, bu after many unsuccesful tries I don't see a solution.
    I tried to make fetches from cursor into a record group (30 nodes on a "page", but it looses a real hierarchy and you should do a lot of programming). If anybody knows how to make the population of the tree faster or have some template / please forward.
    2. After we put the patch 5 of developer6, tree view control is totally unpredictable. Usually its when you programmaticaly try to select a node (ftree.set_tree_selection)...Anybody have the same problems?

    Try taking out the 'start with' and 'connect by' clauses in your select statement if you're using them. However, this will mean that you will have to determine the levels of the tree manually and ensure that the data comes out in the same order each time you execute the select statement.

  • How to maintain several views of the same data and update a tree

    I have an object UiUser, which is displayed in my application in several different views. There are three different views which all have the User object i.e. search results, user tree and user table. Each of the views has the same menu items, so the user can be deleted from any of the views.
    What I am trying to work out is how should I ensure the item is updated in all of the views?
    I can fire a property change event with the UiUser and update two of the views i.e. search results and user table, but how do I update the tree?
    I thought of overiding the equals/hashcode methods of the UserTreeNode to compare uiUser.getId () and I could then search the tree and find the tree node of the required UiUser. But I have reservations about this whole approach as it just seems wrong.
    Any ideas of how to keep N views in sync, I really don't want all of the views to have tree nodes as this equally seems wrong. This should be a simple problem to solve and I'm sure lots of people have done it, I'm just not sure which is the best approach to take.

    Hi Jan,
    This is so because each installer has a GUID that is used to check whether the application needs to be upgraded or not. (It's a Microsoft function).
    What you can do is create a new installer with a different GUID (copy the installer in the projects), and check witha  text editor whether this GUID has changed.
    But any specific reason you need two seperate installs? You can run the application twice with a specific INI token:

  • How to create a tree view to show hierarchy

    Hi all,
    i am new in plugin development.i need help in creating a tree view to show hierarchy.i gone through sdk\paneltreeview example.but not getting clear idea how to create child node.and how to display it..i want to create a simple tree view which displays my custom data as root\child in hierarchy as i want.
    thanks..

    I did this in CS3 a few weeks ago...
    1. subclass NodeIDClass to create your node id class.
    2. subclass ITreeViewHierarchyAdapter to create the adapter
    3. subclass CTreeViewWidgetMgr
    4. in your .fr file, define two "Class"'es based on kTreeViewWidgetBoss (with Interface IID_ITREEVIEWWIDGETMGR and IID_ITREEVIEWHIERARCHYADAPTER) and kTreeNodeWidgetBoss.
    Btw, I put down "persistentlistui" in my note so I guess I looked at that sample instead of the paneltreeeview.
    Good luck.
