Event Handling in Tree structure

Hi all,
I have created an alv tree structure using the FM's 'RS_TREE_CONSTRUCT' and 'RS_TREE_LIST_DISPLAY'. Can anyone tell me how to handle double-click event with these FM's. My requirement is that i should display the tree structure of the Materials from Raw material till Finished materials and i have done that. After that, when i select one of these materials (Either double-click or provide some icon for each item and select that icon), i should be able to call an existing report with the data of the line selected.
Any help will be greatly appreciable.
thanks and regards,
Raja Sekhar.

Hi Raja..
This post was from long back..
And today i have same requirement.. So could you tell me that what you have done for this...
Thanks in Advace

Event Handling for tree structure using "CL_GUI_ALV_TREE_SIMPLE"

Hi,
I have created a tree structure using class CL_GUI_ALV_TREE_SIMPLE.
Now I wanted to insert a check and give message when the user opens the last node in my structure.
I checked the events available in the class , but there in none which gets trigered when we try to open a node.
Please guide me with this scenario.
Thanks & Regards,
Omkar M.

Hello Omkar
The solution is somewhat odd but apparently works. As sample report please check BCALV_TREE_SIMPLE_DEMO.
Copy this report and make the following changes:

As soon as you open a node in the ALV tree the report will stop at the break-point.
Now you need to check if there are still children nodes to be displayed.
If not then trigger your special coding.

Action Event Handler on Tree nodes

I have an actionListener event handler registered on a tree node as follows:
<af:tree value="#{bindings.SomeViewObj1.treeModel}" var="node" rowSelection="none" id="t1"
binding="#{EditFormBean.tree1}" displayRow="selected" summary="Tree"
partialTriggers=":::cb1 :::cb2">
<f:facet name="nodeStamp">
<af:panelGroupLayout id="pgl3">
<af:outputText value="#{node}" id="ot1"/>
<af:commandImageLink text="E" id="cil3" partialSubmit="true"
*actionListener="#{EditFormBean.onEdit}"* binding="#{EditFormBean.cmdImageLink}">
<af:setPropertyListener from="#{node.hiertType.structureDefName}" type="action"
to="#{viewScope.formView}"/>
<f:attribute name="node" value="#{node}"/>
</af:commandImageLink>
<af:commandImageLink text="A" id="cil1"/>
<af:commandImageLink text="D" id="cil2"/>
</af:panelGroupLayout>
</f:facet>
</af:tree>
I have at each node stamp facet a panelGroup Layout that contains the node value and a command Image link. The tree has two hierarchical levels. When I press the command Image link on the first tree noe level, the actioListener method in teh managed bean (EditFormBean.onEdit) gets called. When I press the same commandImage link on the second tree level, the same action listener does not get called. I need to get past this problem before I code the actionListener which needs to set the current row in the iterator based on the key selected on the tree node. I simply have a print statement in the action listener method which shows something when the first level command image link is clicked but does not print anything when the second level command image link is clicked.
I am using JDeveloper 11.1.2.1.0
There is also adf faces code around this snippet that uses an af:switcher facea component to display the appropriate form based on the nodee level in which the comman d image link is clicled but it is irrelevant to the problem I am getting.
Any help on that would be appreciated

Hi,
hard to say . Didn't see this before. Can yoiu remove "binding="#{EditFormBean.cmdImageLink}"" from the command link. The tree stamps its children so that it doesn't make sense to keep a handle to the component instance

Hello Goh
Based on your coding you are using CL_GUI_ALV_TREE instead of CL_GUI_COLUMN_TREE.
Calling method get_selected_item within your event handler method is unnecessary because these data are already provided by the event interface.
[code]METHOD handle_item_double_click.
DATA: lt_selected_nodes TYPE lvc_nkey,
lt_fieldname TYPE lvc_fname.
*$Comment: unnecessary because these data are already provided
by the event interface (IMPORTING nodekey fieldname).
Determine which line is selected
**CALL METHOD gd_tree->get_selected_item
**IMPORTING
**e_selected_node = lt_selected_nodes
**e_fieldname = lt_fieldname.
ENDMETHOD. "handle_item_double_click[/code]
The following sample is based in report BCALV_TREE_04 but can be simply applied to your application:
[code] METHOD handle_item_double_click.
define local data
    DATA:
      ls_outtab     TYPE sflight.
    FIELD-SYMBOLS:
      <ld_fld>      TYPE ANY.
Call this method to get the values of the selected tree line
    CALL METHOD g_alv_tree->get_outtab_line
      EXPORTING
        i_node_key     = node_key
      IMPORTING
        e_outtab_line = ls_outtab
       E_NODE_TEXT    =
       et_item_layout =
       ES_NODE_LAYOUT =
      EXCEPTIONS
        node_not_found = 1
        OTHERS         = 2.
    IF sy-subrc <> 0.
    MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
               WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.
    ENDIF.
    ASSIGN COMPONENT fieldname OF STRUCTURE ls_outtab TO <ld_fld>.

... Call transaction with selected (item) value.
    ENDIF.
ENDMETHOD.                    "handle_item_double_click[/code]
The ASSIGN statement will work if no item of the hierarchy part is selected.

Question on program structure about event handling in nested JPanels in GUI

Hi All,
I'm currently writing a GUI app with a wizard included in the app. I have one class that acts as a template for each of the panels in the wizard. That class contains a JPanel called contentsPanel that I intend to put the specific contents into. I also want the panel contents to be modular so I have a couple of classes for different things, e.g. name and address panel, etc. these panels will contain checkboxes and the like that I want to event listeneres to watch out for. Whats the best way of implementing event handling for panel within panel structure? E.g for the the checkbox example,would it be a good idea to have an accessor method that returns the check book object from the innerclass/panel and use an addListener() method on the returned object in the top level class/panel. Or is it better to have the event listeners for those objects in the same class? I would appreciate some insight into this?
Regards!

MyMainClass.main(new String[] { "the", "arguments" });
// or, if you defined your main to use varags (i.e. as "public static void main(String... args)") then you can just use
MyMainClass.main("the", "arguments");But you should really extract your functionality out of the main method into meaningful classes and methods and just use those from both your console code and your GUI code.

There is any function module to give the F4 help in custome development for Training Event like Tree structure in PSV2.

Check AL S's response here for how to do this. CVI 6.0 does not have a native Tree control. This was introduced with CVI 7.0.

Tree's DragSource changes at DragDrop event handler?

I try to drag a node A into node B. When the DragDrop event
handler is called, the dragSource is changed to the drop source?
I have declared the following:
<mx:Tree ......... dragDrop="OnDragDrop(event)"....../>
In the function:
private function OnDragDrop( event:DragEvent ):void
var ds:DragSource = event.dragSource;
items = new XML( ds.dataForFormat("treeItems")[0] );
I was expecting the "items" has a copy of the dragged item
(node A). However, it has all the drop node's info (node B). How do
I get teh drag and drop nodes in this event?
P.S. I am trying to drag and drop at the same tree control.
Could that be why? Is it suppose to be like this? Or, its a bug?
-Alan

Regarding your button look and feel issue, the easiest thing to do would be to copy the button template you are using for the template-based buttons and modify that to add in your onClick handlers.
The builtin button template for the theme I am using (Theme 12) looks like this
<table class="t10Button" cellspacing="0" cellpadding="0" border="0" summary="">
    <tr>
        <td class="t10L"><img src="#IMAGE_PREFIX#themes/theme_10/button_left.gif" alt="" width="4" height="24" /></td>
        <td class="t10C">#LABEL#</td>
        <td class="t10R"><img src="#IMAGE_PREFIX#themes/theme_10/button_right.gif" width="4" height="24" alt="" /></td>
    </tr>
</table>In other words, each button is rendered in its own HTML table.
Copy this button template, call it mybutton and have it look like
<table class="t10Button" cellspacing="0" cellpadding="0" border="0" summary="">
    <tr>
        <td class="t10L"><img src="#IMAGE_PREFIX#themes/theme_10/button_left.gif" alt="" width="4" height="24" /></td>
        <td class="t10C">#LABEL#</td>
        <td class="t10R"><img src="#IMAGE_PREFIX#themes/theme_10/button_right.gif" width="4" height="24" alt="" /></td>
    </tr>
</table>Notice that I put a no-op in the href tag for the button and added a onClick handler that will do the real work. In your case, you would use the URL Redirect on the Button attributes page to call your SavePage() function. Since the onClick is called before the href, it should (hopefully) do what you are looking for.
I put up these changes at
http://htmldb.oracle.com/pls/otn/f?p=24317:26
Do let us know.

JDEV 10.1.2 UIX Tree Event Handler

Hi,
I have built my tree bound to two ADF entities/views.
It works fine in a small standalone application, but as soon as I try to integrate it with my main app it fails to call either the "null" or the "expand" event handler (null for page rendering and expand for... well expanding the node (see below))
I've run it in debug and the event code just isn't getting fired
There must be something in my main app that is intercepting the event handler before it gets to my uix handlers.
New to all this so any help greatly appreciated!
In summary, what would intercept default event handling in a uix page.
Thanks
Mark
<handlers>
<event name="expand">
<method class="view.TreeUtils" method="doTreeEvent"/>
</event>
<event name="null">
<method class="view.TreeUtils" method="doTreeEvent"/>
</event>
</handlers>

Hi,
it appears that if I change the forward to have 'redirect="true"' within the struts config file then this works fine now.

Report using a tree structure

I have found function modules RS_TREE_CONSTRUCT and rs_tree_list_display
but they enable me in having only 1 line at one level of the heirarchy , my requirement is to have multiple lines at one level of the tree.
I have found a function module TREEV_CREATE_LIST_TREE which i can not figure out how to use . Any help from the experts ?
