Tree component menu

Hi guyz,
I’ve developed a menus using
Tree Component with
xml connector. can anybody help me to control its speed,
like in my scenario;
suppose, 3 nodes captioned (item 1 & item 2),
- item 1 has 10 sub items and item 2 option has 5
issue #1: there's no speed synchronization b/w both (item1
& item2). item 1 has take more time to popup then item2 coz of
xml data.
issue #2: I want to increase the speed of popup or scrolling.
Please help me that how can I optimize my menu and resolve
these issues. Please tell me any book, development kit (software),
extensions etc. for reference or help.
Thanks
mail me
Raheel

there is pool size error is coming.Why do people allude to an error without posting the actual error message?
(in other words - please post the full error message/stack trace)

Binding menu model to a tree component

Hi,
I have generated menu models to all my unbounded task flows in my application and I want to display the menus as a tree in the side bar ...
The hosted demo here tells that we can add the same menu model to a tree component...
http://jdevadf.oracle.com/adf-richclient-demo/faces/components/pagehierarchy/page.jspx?_afrLoop=14156998585414802&_afrWindowMode=0&_afrWindowId=null
Is it possible to bind a menu model to a Tree component? If possible...how to achieve this? If not...Is there any other way we can display the application menu in the form a tree...using the existing menu models?
Edited by: user12747136 on Apr 13, 2010 12:26 AM

Hi,
I don't understand your question. You simply can use the tree and specify the MenuModel as its value and define the right detailStamp, like any kind of tree. Or was your question more general like how to use a tree?

Use of tree component as menu

hi..
i want to use tree component which will work as menu.Like it should give options and when we choose one option it should show dialogue box with required functionalities.Please suggest me how to implement it in Javafx

Thinks

Sans,
I am no Apex expert, but with a situation as "complex" as yours, have you thought about creating a VIEW that joins these 7/8 tables, placing an INSTEAD OF trigger on that view to do all the business logic in the database, and base your application on the view?
This is the "thick-database" approach that has been gaining momentum of late. The idea is to put your business logic in the database wherever possible, and let the application (Form, Apex, J2EE, whatever) concentrate on UI issues,

Tree Component as swf

I have a swf file that is a Tree Component... (So when it
diplays it looks like a Directory structure with folders and files)
Some nodes access url links... And some access .doc files on
the network... This works fine when I run it from my local site,
but when I run it on the remote site (Intranet server) the nodes
that reference file paths so nothing, instead of opening the file,
the url type links do work fine on the remote site.
Any thoughts on why this might be occurring ? I am putting
the swf and the associated xml file and html page on the remote
site... Am I missing a file or setting on the server that I have
locally? I am also including my .as file and xml file for review.
Any help would be greatly appeciated.

It is quite a pain in the rear to skin the AS2 components.
And I don't know of many 3rd party components for AS2. I know of
plenty AS3 3rd party components, but if you were using AS3
components you wouldn't need a Tree to replicate the adobe video
workshop type navigation, all you would need is the built in List
component. If you can go sans icons, I would suggest using the AS2
List to get the feel you're looking for.

JDev10g: Using a Tree component based on different queries.

Hello,
I've been doing some research on how to implement a tree component in ADF which I got working. However I need to implement a tree component that uses several different queries.
The parent node would be one query, the child/leaf nodes would be based on another query but still related to the parent.
For Example: 'select parent_nodes from mydatabase' then 'select child_nodes from mydatabase where child_nodesID = parent_nodesID'
This will ultimately have to branch down more levels but I'm not sure exactly how to achieve this. I'm thinking I have to create new View Objects but I'm not sure exactly how to do that either.
Thank you in advance.

For an SQL query on a database use a View Object. First, you will need to create a new Entity object to represent each table in the database you need to use in the queries. Once you have created your view objects with their correct SQL queries, you need to specify how they are related. Example:
RootView is all elements with ParentId of null.
OtherView is all elements with ParentId not null.
RootToOtherLink is a view link which links RootView.Id to OtherView.ParentId. You can specify this in the dialog. You will want to select all accessors available to make your life easier later, but make sure to name them something you will recognize, like "RootToOtherDestination".
You will also need OtherToOther Link which links OtherView.Id to OtherView.ParentId. This starts the recursive nature of the hierarchical relationship.
Once you have this set up, you will need to create an Application Module so that you have a data control you can bind your tree to. Set up the data model in a hierarchical fashion using your link.
This will create a data control on the Data Controls pane you can drag onto your .jspx page. A menu will show up from which you can select tree component. This will take you to the tree binding dialog. Here is where all your work so far will pay off. You want to click the green plus button to add your RootView. Then, with the RootView selected you will want to hit the green plus again to select your destination accessor, such as "RootToOtherDestination" as mentioned earlier. This will show the OtherView as a child of the RootView. Finally, with OtherView selected you will want to hit the green plus again and select your other destination accessor, such as "OtherToOtherDestination". Select the attributes you want to have available to your tree at the bottom of the dialog and click ok.
Your tree will show up. If you want to customize the way it looks or especially the attributes it displays in a node, those can be edited in the <af:tree> tag on your .jspx page.

Slide presentation and Tree component

Hello there,
I'm trying to develop a small multimedia application which
will use the Tree component as the menu navivation. I've managed to
setup the tree object and load the menu titles from an external
.xml file. The problem i'm experiencing is that i cannot assign
actions to the menu selections so it will jump to their respective
slide. I have placed the tree component inside a movie clip and at
the presentation level. On first key frame of the movie clip i've
placed this
code but
still can't refence the slide2.
Thank you in advance,
Deann

Not sure, would have to try it myself, but try evt.target
instead of this.

Customizing the Tree Component

Is there a way to set different font sizes and colors for
different levels of the tree menu?

I am guessing that you are using AS2 components, as there is
not a default Tree component for AS3...
I don't know about font sizes, but you can set depth colors
for the AS2 Tree.
The following will set the background colors to black, medium
grey, lighter grey for the Tree that is named "myTree":
var colorArray:Array = new Array();
colorArray.push(0x000000);
colorArray.push(0x555555);
colorArray.push(0x999999);
myTree.setStyle( "depthColors", colorArray );
Note that this is based on the depth. IE for the node
structure:
<node label="First Level">
<node label="Second Level">
<node label="Third Level">
</node>
</node>
</node>
First Level with have a black background, Second Level will
have a medium grey background and Third Level will have a lighter
grey background.

Custom icon per entry in the AS2 Tree Component (using CS3)

I have a tree component that loads its data from an XML file and I wonder if I can customize every entry to have its own icon by adding an icon attribute to every entry in the XML and giving the tree an action to read that icon (which would exist in the library of the Flash file). My goal is to reproduce a tree within an application that my company is developing (it's for a training tool related to that application).
My XML says something like <node label = 'Label' heading = 'LABEL' desc = 'Description' icon = 'icon1' />
My label is what the tree displays, the heading is what the information dialog in the training tool displays as a title bar, the desc is what the training tool displays within the body of the text for the function description and the icon is what I want to be a reference to the graphic in the library to place as an icon in front of the item rather than use setStyle with the properties for disclosure, leaf, and folder icons.
Is that possible? I haven't found a solution for it yet.

I've never used the Tree component, so I'm just guessing here....
There is a slight delay before the xml file loads and your tree has its data provider.
Perhaps during that time there is no node at mTree.getTreeNodeAt(0) to open? Try adding this just before the last line of your code:
trace("the node is: "+mTree.getTreeNodeAt(0));
What do you get?
You might need to move that code inside the xml's load event handler.
Another thing is that the Flash components tend to work on an invalidate-then-wait-one-frame-to-redraw kind of model. So it is possible you will need to wait one frame after the xml has loaded and then tell it to open that node.
The doLater method might help with that.
var home:MovieClip=this;
var xmlTreeData:XML = new XML();
xmlTreeData.onLoad = function() {
mTree.dataProvider = this.firstChild;
mTree.doLater(home,"delay");
xmlTreeData.ignoreWhite = true;
xmlTreeData.load("xml/treeValues1.xml");
mTree.setStyle("fontSize","11");
mTree.setStyle("selectionColor","0xE0E0E0");
mTree.setStyle("useRollOver",false);
function delay(){

Label display issue in Tree component when it is having vertical scrollbar

I am using tree component as dropdown factory for combo box. When i open dropdown, it doesn't have vertical scrollbar and all the root nodes are getting displayed correctly(in closed mode). Now if i try to open any node, i am getting vertical scrollbar as the child nodes are more. Now the problem is if scroll down, some of the nodes(labels) are not getting displayed but i am able to see the icon. If i keep on scrolling bottom to top and top to bottom, some of the nodes are showing labels and some are not(It is inconsistant).
I have not used any custom item renderer for tree control. I used my custom dataDescriptor which i have implemented from ITreeDataDescriptor. Also I tried extending DefalutDataDescriptor, but no luck.

Does it work if the tree is not in a combobox?

Layout issue with af:tree component

I am using af:tree component but I am finding layout issue with it. I have a requirement where in I need the tree to stretch to the available space but a horizontal and a vertical scrollbar comes up automatically. Is there a way to handle this issue?

User, without your jdev version it's hard to help.
Have you embedded the tree component in a stretch layout?

[F8] Tree Component: How can I hide/remove the scrollbar and border?

I'm using the Tree Component in my Flash 8 Pro - Project. I'm
trying to customize the look of the Tree component in two ways:
1. Is there any way to remove the scrollbar from the Tree
Component?
2. Can I also remove the Border from the Tree Component?
I checked the Component Inspector and couldn't find any
options for the scrollbar nor the border.
Does anyone know how to do this or could you point me in the
right direction?
Thanks

You can use the Status-4-Evar extension to replace some functionality that was lost withthe removal of the Status bar in Firefox 4.
Open the Customize window via "View > Toolbars > Customize" or via "Firefox > Options > Toolbar Layout" after you have installed the Status-4-Evar extension and drag the items (Status Text, Progress Meter, Download Status) upon the Add-ons Bar (View > Toolbars > [X] Add-on Bar)

Tree Component Icons

I'm using the tree component for a little Windows Parody I'm making. In my .fla, There's a tree component that loads an external XML file. I can't figure out how to add custom icons to my component, though.
I know it's possible to set the icons for just the default folder and file icons, but since it's a Windows Parody, there'll be different icons for different file types, folder types, etc.
In other words, I'd like to have a different icon for every item in my Tree component.
How can I do this?
Here are the contents of my XML file:
<node>
    <node label="Desktop">
</node>
    <node label="Documents">
<node label="Pictures" isBranch="true" />
<node label="Movies" isBranch="true" />
<node label="Games" isBranch="true" />
<node label="Video" isBranch="true" />
</node>
    <node label="Computer">
<node label="Local Disk (C:)" isBranch="true" />
<node label="Local Disk (D:)" isBranch="true" />
<node label="DVD-RAM Drive (E:)" isBranch="true" />
<node label="DVD/CD-RW Drive (F:)" isBranch="true" />
</node>
<node label="Readme.txt" isBranch="true" />
</node>
And the code on the first frame of my .fla file. The Tree's name is "fileTree", and the XML file is "doors_explorerXML.xml".
//Tree
var fileDP:XML = new XML();
fileDP.ignoreWhite = true;
fileDP.load("doors_explorerXML.xml");
fileDP.onLoad = function() {
    fileTree.dataProvider = this.firstChild;
Also, I don't need to have an XML file loaded. If there's an easy way that does it all within Flash, please tell me. I just need to be able to handle events from the Tree.

Im having the same issue. I dont know how to change the tree icons separately with the xml. Is there anyone who knows how to do it?
This is what I got so far. However, i can only get my first branch to show custom icons. I tried ALOT, but i guess I´m doing something completely wrong.
Here is the code for my tree so far:
my_xml = new XML();
my_xml.ignoreWhite = true;
my_xml.load("tree.xml");
my_xml.onLoad = function(){
myTree.dataProvider = this.firstChild;
var folders = my_xml.firstChild.firstChild;
var docs = folders.childNodes;
for (var i=0; i < docs.length; i++){
currDoc = docs[i];
trace(docs[i]);
var docIcon = currDoc.attributes.pic;
switch(docIcon){
case "pdf":
myTree.setIcon(currDoc, "pdfIcon");
break;
case "word":
myTree.setIcon(currDoc, "wordIcon");
break;
case "excel":
myTree.setIcon(currDoc, "excelIcon");
break;
case "ie":
myTree.setIcon(currDoc, "ieIcon");
break;
}//switch
} //for
};//onLoad
And here is the XML I used:
<node label="» Dokument typer">
<node label="» links - document">
<node label="test.url" url="http://www." pic="ie" info="test text" />
<node label="test.doc" url="test.doc" pic="word" info="test text" />
<node label="test.excel" url="test.xls" pic="excel" info="test text" />
<node label="test.pdf" url="test.pdf" pic="pdf" info="test text." />
</node>
<node label="» Links - document">
<node label="test URL" url="http://www." pic="ie" info="test text." />
<node label="test URL" url="http://www." pic="ie" info="test text." />
</node>
</node>

Questions about AS2 Tree Component (Flash CS3)

I have Flash application with a Tree component on the Stage. I'm using an XML file to create the structure of the Tree component.
Each entry on my XML has the attributes id, label, heading, desc, and icon.
My problem is that I can't seem to be able to set the Tree to default with the first node open.
My code is:
var xmlTreeData:XML = new XML();
xmlTreeData.onLoad = function() {
mTree.dataProvider = this.firstChild;
xmlTreeData.ignoreWhite = true;
xmlTreeData.load("xml/treeValues1.xml");
mTree.setStyle("fontSize","11");
mTree.setStyle("selectionColor","0xE0E0E0");
mTree.setStyle("useRollOver",false);
mTree.setIsOpen(mTree.getTreeNodeAt(0), true);
My tree populates fine, and the handler I retrieve whatever item is clicked works great. However, the tree refuses to default to having that first node open.
I'm also interested in placing custom icons into certain nodes via the icon attribute I've set in the XML, but that will have to come later I guess.

I've never used the Tree component, so I'm just guessing here....
There is a slight delay before the xml file loads and your tree has its data provider.
Perhaps during that time there is no node at mTree.getTreeNodeAt(0) to open? Try adding this just before the last line of your code:

Ext. data source and Tree component

Im using tree component and XMLConnector here.
as far as i can see results in my tree (when testing my
movie) it ouputs data thats loaded fom ext. XML file.
But the problem is that it publishes [type Function] in the
tree.
no actual xml nodes are visible, just bunch of [type
Function]
ive also searched for info / tutorial how to publish actual
xml data in the tree component but without any luck.
So what should i do and how ?

Solved
xml tags needed just a label with attributes
