Code for Tree component(tomahawk )

I am new to JSF,I want a tree component in my page and i want to construct the tree by retriving data from database.I searched most of materials but could'nt find any good one.

How would it match the trees? What have you done so far?

Horizontal scroll for Tree component scrolls too far right

I've enabled the horizontal scroll bar for the Tree component.
But the scroll bar allows the user to scroll very far to the right into blank space.
The maximum width of my components measures 124px, as calculated by measureWidthOfItems(0,0), and I've verified this by measuring pixels of a screen shot.
I have tried adding an event to set the Tree.maxHorizontalScrollPosition, and I traced the value that I'm setting it to, and I also traced the value that it actually assumed after I set it. Both are 124px.
So I can't understand the behavior. I can scroll something more like ~400px to the right with lots of blank space.
Any ideas why?
Thanks,
David

Hmm, I'm not sure why this works, but it works, so for completeness here's what I did (in case anyone else runs across this same thread):
var measWidth:Number = myTree.measureWidthOfItems(0,0);
filesTree.maxHorizontalScrollPosition = measWidth - myTree.width;
I call the above code whenever the window is resized (in my app there are 2 places that can cause a resize of the window, I manually added calls to a function with the above code). There is also an example out there that resizes any time the window is resized, but if you do this then you really can't have liveDragging=true in a DividedBox (which I have) because the cost of resizing is very high and overtaxes the cpu when called many times consecutively. I just call it when the dragging is finished (that way I have live dragging enabled, but it only updates the scroll bars when the user stops dragging, which is visually acceptable).

Garbage Collection Issue for Tree Component

Dear:
When I created a new Tree instance dynamically by following code, and clicked any tree node randomly and then I removed it via another button, but I found this instance couldn’t be removed by GC, if I just created this tree without mouse action, it can be removed by GC.
Tree Component:
-- TreeView
<mx:canvas>
<mx:Tree dataProvider="{data}" />   // data is a XML staments
</mx:canvas>
Create Tree:
           public function createView(event:Event):void{
              var view:TreeView = new TreeView ();
              view.name="myTree";
              addChild(view);
              view=null;
Remove Tree:
           public function deleteView(event:Event):void{
              var view:TreeView= TreeView( _con.getChildByName("myTree"));
              removeChild(view);
Could someone give me some suggestion?
Thanks a lot

Hi ajmcfarlane,
This is my first post here. I'm fairly new to AS3 still and
have been getting my education from a number of places. The best
education i have found is from the book located at
http://www.learningactionscript3.com/
Rich Shupe address this problem of removing the child from
memory. I Downloaded your file and found 2 problems and resolved
one of them. By now you might have already solved this anyway.
To remove the child from the Display List use -->
removeChild(myChildObject);
To remove the object from memory use --> myChildObject =
null;
You did these two steps but in the incorrect order, just by
moving the 'myChildObject = null' under the removeChild code makes
it work.
I found running a few trace statements after fixing the first
problem, i found the second problem. The error of trying to remove
a child when it is no longer there.
You just need to rework the design so that the order of
events fires as you want. Below is the traces i used and the output
that is received.
function Click1(e:MouseEvent){
trace("four ", loadedcontent);
modLoader.unload();
modLoader = null;
function unloadCompleteHandler(event:Event):void{
trace("one ", loadedcontent);
removeChild(loadedcontent);
trace("two ", loadedcontent);
loadedcontent = null;
trace("three ", loadedcontent);
output
Loaded mem: 20668 KB
four [object MainTimeline]
one [object MainTimeline]
two [object MainTimeline]
three null
unLoaded mem: 23352 KB
So you can see the click event is firing of the unload first,
when i think you want that last.
I hope this has been of some help :)

2 Line Text for Tree Component

Hi
I am trying to use a tree component for a Course navigation ,
and I have a Node names Getting clipped and I wanted to have
mulitple lines in the tree node, I would appreciate if anyone could
help me in how the tree component can be extended to accomodate
this requirement.
Thanks

Hi Begum,
There are few default attributes you need to fill in your data structure,
PARENT_KEY - Parent (in your ex : header1, header2)
ROW_KEY - Children (col1, col2, col3, col4...)
EXPANDED
IS_LEAF -
TEXT
CHILDREN_LOADED
IMAGE_SRC
Include these fields with same name in your structure(structure of the table filling CT_DATA in GET_DATA method) and fill the relevant data, output will be displayed.
Cheers,
Vemula.

Save last selected and state for Tree Component?

I have a Tree component that refreshes its data everytime I
open the Tab containing it (doing a SQL call to return an index of
models). The problem is that everytime the dataProvider changes (a
new one overwrites the old one) with databinding, even if the data
is exactly the same, it loses its old state and selected node. Is
there any way to save this state/selected node when the
dataProvider updates?

good article on all aspects of trees including your issue.

Data Binding for Tree Component

Hi ,
I have to make a tree structure and bind it to a column in a table,
which when expanded should list the rows of the table for the selected column as individual sub nodes of the tree.
So far I am not able to get that done.
Any suggestions how to do it?

If find what I need among ADF Faces Core component, ... the ADF TreeTable (http://www.oracle.com/technology/products/jdev/htdocs/partners/addins/exchange/jsf/doc/tagdoc/core/imageIndex.html).
Unfortunetly It seems quite dificult to integrate ADF or any other 3rd part component with JSC2.

Issue with af:tree component

Hi All,
I am using JDev 11.1.1.6
I am creating a tree component with collection model.I want to provide different action to each node,so I have defined an action attribute in the bean
which I set in the constructor as shown below
TestTree node1 = new TestTree("node1", "#{TreeBean.action1}");
Is this the correct approach..This gives me "method not found " error when I click on the node.
Below is the code for tree component :
<af:tree value="#{TreeBean.model}" id="t1" var="node"
styleClass="AFStretchWidth" inlineStyle="height:600.0px;">
<f:facet name="nodeStamp">
<af:commandLink text="#{node.label}" id="cl1" immediate="true"
actionListener="#{node.action}"/>
</f:facet>
<f:facet name="pathStamp"/>
</af:tree>

Setting up scrolling for a component which has g2d features...

Hi, everyone, Im working on adding scrolling capablitlity to a component, as it currently exceeds the room I have given it. The problem is....
1) My scrollbar is always hidden under my g2d images... If I click on top of where the scroll bar should be, like crazy it appears piece by piece.
2) The scrollbar doesn't seem to be scrolling. BTW its on a regular panel (getContentPane()), is this a problem??
Well....here's the relevant code (the code for the component)
static class MyComponent extends JComponent {
JScrollBar scroll;
//~~~~~~~~~~~~~~Component Stuff~~~~~~~~~~~~~~~
          MyComponent() {
                    setBackground(Color.pink);
                    setBounds(0,0,500,500);
                    setBorder(BorderFactory.createLineBorder(Color.pink,10));
                    scroll = new JScrollBar(JScrollBar.VERTICAL,0,20,0,100);
                    scroll.setBounds(484,0,16,500);
                    scroll.setVisible(true);
                    add(scroll);
                    System.out.println(scroll.isEnabled() + "" + scroll.isVisible() + scroll.getBounds());
                    setVisible(true);
Then in the main() function, I add it to the panel like so...
MyComponent mc = new MyComponent();
joe.getContentPane().add(mc);
Thanks a lot,
Mark

Ok, I tried making the panel....but this has led to some strange(er) problems...
Here's some info on my panels
JPanel something....is the panel holding buttons, and under a flowlayout i think
ContentPane, i dont know what it holds...
JScrollPane pane...this is hidden from view, unless I set the something JPanel to be hidden.
Why cant i just see them all at the same time? I made sure the JPanel something had opque set to false, and now i can see the contentPane....but where are my g2d objects (located on "something")
thanks...

Hi i have the same problem, Did you found a solution ?

How to create a binding through code for both a table and a query component

Hi,
I have a unique use case where I need to dynamically assign the dataBindings to a query Component and its resultant table component in a page. What I mean is,
1. I have a jsff page with a query and table (no bindings associated)
2. I know the name of the AM and the VO
3. I need to through java code create a DataCntrol bindin for
a. <searchRegion/> for query component
b. <iterator ... /> and <bindings... /> for the table
4. The VO and AM is dynamic and not known at design time.
Is there anyway to achieve this? Please let me know if you need further classification on my question.
Appreciate your input!
Thanks

Script Component WebService Binary code for the script is not found

I am using SSIS 2012 to access a Public Web Service
http://marketinformation.natgrid.co.uk/MIPIws-public/public/publicwebservice.asmx
However, when adding reference to WebService (not Service Reference),
I receive the dreaded msg "Binary code for the script is not found"
I have spent an age ploughing through the forums.
Many replies seem to suggest not using Script Component to acces WebService.
Should I write a .NET app ?
Any thoughts how I should proceed would be most welcome.
thanks JohnJames

Hi JohnJames,
If I understand correctly, you already add this public web service via Add Service Reference option in the Script Component. Then you receive the error message when you trying to call the bindings and Contract settings stored in app.config file to access
the web service.
Please note that we cannot all the web service normal way as SSIS Script Component task doesn’t recongnise the app.config file. To fix this issue, we should define the BINDINGS via code rather than depending on the App.config file. For more details, please
see the following blog:
http://social.technet.microsoft.com/wiki/contents/articles/22587.consume-webservice-via-ssis-script-component.aspx

The binary code for the script is not found error for the Script component - SSIS 2012

Hi,
I'm implementing a SSIS 2012 pkg. For a data flow task, I'm using a Visual Basic 2010 script component with an Oracle input flow. For the script component I've an input column and I've created an output column. Inside the script code I've edited only inside
Public Overrides Sub Input0_ProcessInputRow(ByVal Row As Input0Buffer).
The written code is:
If Year(Row.OFFDATAORI) < 1900 Then
Row.OFFDATAORIconv = CDate(CStr("1900" + "-" + Right("00" + CStr(Month(Row.OFFDATAORI)), 2) + "-" + Right("00" + CStr(DatePart(DateInterval.Day, Row.OFFDATAORI)), 2))
Else : Row.OFFDATAORIconv = Row.OFFDATAORI
End If
It is to note that OFFDATAORI isn't the name of the input column for the script component.
When I close the script component I've an error about "The binary code for the script is not found".
Any helps to me, please?
Thanks

Hi,
I've solved. There was a syntax error, a bit hidden.
Bye
