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.

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).

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.

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 :)

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 name="pathStamp"/>

How do you display multi line text

Hi
How does one display multi line text? I would like to display address information on the screen so that the user can select it and copy/paste it into another application (ms word).
I have the address information as separate columns (address1, address2, city, province, postal code) so I've changed the query on my view object to add it as address1 || chr(10) || address2 || chr(10) || city ....
If I display it on the page as an output text, it all displays as one line (okay, the chr(10) thing did not work but that's beside the point).
In general, is there a way to display multi line text? What component is suitable for this, if there is one?
Thanks

You can use normal outputText components in a panelGroupLayout (vertical layout) and add each attribute to it. The remove the labels or set the components to simple. You can then mark the data in the browser and use normal copy&paste to transfer the data.
If you want to output longer text with line breaks you can use an outputText with escape=false and use the br html tag to generate a line break;
<af:outputText escape="false"
value="+++++++long<br>test<br> this is a long text in multiple lines" id="ot10" truncateAt="#{viewScope.ToggleBean.truncateLength}"/>Timo

Tree component display problem when text too long???

hi all
whenever i use a tree component to display some sort of text, i run into problems when the width of the text being display for a node is larger than the width of the tree component.
Given: Tree tree1 with Node node1 and Child Node child1
When the text of either node1 or child1 is longer than the width of tree1, the text is displayed on its own single line UNDERNEATH the node images. this makes the text look like it does not belong to the group of children of a given node.
is there anyway to add maybe a text area or some sort of scrolling region to allow for any length of text for any node??
thanks everyone!

Yes, you can change the size of the tree node text field. Please see the "Tree Node Component Properties Window" section in the Help Contents within the IDE. Look at the info under the "Appearance" section.

Tree component and loading xml files into text field

Hello and thank you for taking the time to read my issue....
I am making a simple self help application. I have a tree component that loads the different catagories and topics for my help app dynamically via an xml file...no issues there.
I then want it so that when the user cliecks on the actual topic that the TextArea component will load the info from another xml file using the name of the topic as the name of the xml file to make it that much easier for anyone to maintain this program.
So far the code i have is this.
myTreeListener.change = function(eventObject)
    var theSelectedNode = eventObject.target.selectedNode;
    var theSelectedNodeLabel = theSelectedNode.attributes.label;
    topicTextArea.text +=
I am a little fuzzy when it comes to loading the xml file in. Should i be loading html instead of xml is my other question as well?
Thanks in advance for your help
FG

Check out the Oracle XDB Developer's Guide, Chapter 3. There is an example of using BFileName function to load the xml files from a directory object created using create or replace directory. It works really well.

How to put text line just for a moment ?

Hi,
Do you know how to put a text line just for one photo? I mean I have more photos in one portfolio but i need the text line to be seen just for one photo for the others no.
Thank you in advance.

You can use composition for this , where you can insert text frame for that specific photo where you want to add some description and for rest dont use text frame.
Thanks,
