Accessing Dynamically created Button

Hi,
Can someone give me an example how to access dynamically created button?
I know how to create a button dynamically but don't know how to access from AS3.
Thanks!

Adding f:Attribute dynamically to a dynamically created Button

Hi ,
I am trying to dynamically create a CommandButton and attach a f:Attribute to the same. But somehow I am not able to get hold of the correct API to do the same -
>RichCommandButton button=new RichCommandButton();
>button.setText("Ok");
>AttributeTag attr=new AttributeTag();
>attr.setValue("DC_OPERATION_BINDING", "bindings.DENY");
>button.getChildren().add(attr);
The issue is that the add method expects a UIComponent and attr is of type com.sun.faces.taglib.jsf_core.AttributeTag

gues u can use it like
button.getAttributes().put(DC_OPERATION_BINDING", "bindings.DENY");
{code}

Futureproof and dynamically created button

I have been looking solution how to make buttons dynamically so that I can fetch dynamically values for buttons:
- value,onclick,class,type,request
This excellent page has very closely what I am looking: http://www.laureston.ca/2012/04/20/simple-workflow-implementation-in-apex/
but I have challenges getting the escaped special characters to work especially for the apex.submit - part.
Maybe that is just because 'copy-pasting' the plsql-region code from www-page didn't work out of the box
Application Express 4.2.3.00.08
Because dealing with the escape chars make the page easily break and there are now the new dynamic actions, I need to check what would be futureproof way of dynamically creating the buttons.
If this is anyway the most practical way to proceed, then where I should look for further information about htp.p(....) button creation examples with rich escapes?
Made small test page, where you can see one of my trials trying to get the escapes right.

--below the code for dynamic plsql region -- very likely the escape chars are not copypasted and shown correctly:

</button>');
end loop;
END;

Hi Paavo,
Your right about the button_id. It's value comes from an input parameter. The button won't show up in the "When button pressed"-list_of_values. This is not only because you write the id yourself, but more because the entire button is created on the fly. The button isn't stored internal in an apex table, that's why it won't show up in a list of values.
If you want to trigger a dynamic action with the button, you can use a jQuery selector as triggering element. Here you can refer to the button_id using the '#' as jQuery marker for ID, e.g. '#myButton'.
What the button that you render does, depends on what you put in the p_link parameter. A normal save button would submit the page with condition 'SAVE', you can do that by setting p_link to 'apex.submit("SAVE")'. If the button should do a page redirect, you set p_link to 'http://www.page2go.com', or whatever url you wish to redirect to.
The text you put in the button attributes is added as HTML element definition, so if you set p_attrs to 'alt="alternate text"', that will be added to the html of your button.
An example for a conditional button call could be:
      if p_order_id is null
      then
        create_button
          ( p_id        => 'newOrder'
          , p_link    => 'javascript:apex.submit("CREATE"');'
          , p_label     => 'New Order'
          , p_css       => 'customButton'
      else
        create_button
          ( p_id        => 'updateOrder'
          , p_link    => 'javascript:apex.submit("SAVE"');'
          , p_label     => 'Update Order'
          , p_css       => 'customButton'
      end if;
This would create a 'CREATE' button for a new order (p_order_id is null), or a 'SAVE' button for an existing order.
Regarding your ps: if you mean can you conditionaly create a button using dynamic actions? Then the answer would be yes. Yes you can use the create_button procedure in a dynamic action, however by writing it as stored procedure in the database, or in a database package, you can easily reuse your code and still have only one version of your procedure that you need to maintain.

(Urgent) Dynamically created buttons: which one?

I need to dynamically create an array of gridpanels. There is a button and some other components on each gridpanel. I need to implement an action handler for the button (using method binding). But how do I know which button fires the event?
Thanks a lot!

Hi,
One of the possible solutions is:
Have a hidden field in the form. For each of the buttons write a javascript onclick event method in which the id of the button clicked is assigned to the hidden field. The value of this hidden field is available in the method handler. This helps in identifying which button was clicked.
Hope this helps
Cheers

For loop and xml - how to point the right content in a XML file with a dynamically created button?

Hi Everybody,
as my first experience in AS3 I'm bulding a photo multigallery. In that gallery I have some buttons, each one pointing to its respective set of images.
Each button is created with the for loop, that picks the information from a XML file. From this XML I get the text of the button, the position etc. What I did with some sucess. But there is a scary problem: I don't know how to make each button load the respective and unique set of images.
I've tryied several different methods, with no effect, to make each loop to give to each button an unique identity to load the respective set of images.
I imagine that the solution pass by the use of arrays. I wrote some code, and I guess that I'm almost there (but not sure). Here is my AS3 code until now:
// CREATE MENU CONTAINER //
var menuContainer:MovieClip = new MovieClip();
menuContainer.x=10;
menuContainer.y=300;
addChild(menuContainer);
// CREATE IMAGES CONTAINER //
var imagesContainer:MovieClip = new MovieClip();
imagesContainer.x=10;
imagesContainer.y=10;
addChild(imagesContainer);
//// LOAD XML ////
var xmlLoader:URLLoader = new URLLoader();
xmlLoader.addEventListener(Event.COMPLETE, whenLoaded);
xmlLoader.load(new URLRequest("XML/roiaXML.xml"));
var xml:XML;
function whenLoaded(evt:Event):void {
     xml=new XML(evt.target.data);
     var mySetsList:XMLList=xml.children();
     //// MENU BUTTONS ////
     // CREATE ARRAYS //
     var totalArray:Array = new Array();
     var setNodesArray:Array = new Array();
     var setNamesArray:Array = new Array();
     // POSITIONING BUTTONS INSIDE MENU CONTAINER//
     var rowsQuantity:Number=3;
     var columnsQuantity:Number=Math.ceil(mySetsList.length()/rowsQuantity);
     var cellWidth:Number=160;
     // CREATE BUTTONS //
     for (var i:int=0; i< mySetsList.length(); i++) {
          var newSetButtonMC:setButtonMC=new setButtonMC();
          //what do I do here to make it works? To give each button created a unique id.
          setNodesArray.push(i);
          //trace(setNodesArray);
          var imageNodesArray:Array = new Array();
          for (var j:int=0; j<mySetsList[i].IMAGE.length(); j++) {
               imageNodesArray.push(mySetsList[i].IMAGE[j].attribute("imageTitle"));
          totalArray.push(imageNodesArray);
          newSetButtonMC.setButtonText.text=mySetsList.attribute("galeriaTitle")[i];
          newSetButtonMC.setButtonText.autoSize=TextFieldAutoSize.LEFT;
          var cellX:Number=Math.floor(i/rowsQuantity);
          var cellY:Number=i%rowsQuantity;
          newSetButtonMC.x=cellX*cellWidth;
          newSetButtonMC.y=cellY*(newSetButtonMC.height+10);
          newSetButtonMC.addEventListener(MouseEvent.CLICK, onClick);
          menuContainer.addChild(newSetButtonMC);
     totalArray.push(setNodesArray);
     //// MENU BUTTONS ACTIONS ////
     function onClick(mevt:MouseEvent):void {
          trace(totalArray [0][0]);
          trace(totalArray [0][0]);
          // in the line above I achieved some success loading a specific info from XML.
          // but I don't know what to do with it.
          //what do I do here? To make each button to load its own node from XML.
Here is my XML:

Thanks everyone . ABSTRATO

you can assign each newSetButtonMC and ivar property that points to its i value or, even easier:
// CREATE MENU CONTAINER //
var menuContainer:MovieClip = new MovieClip();
menuContainer.x=10;
menuContainer.y=300;
addChild(menuContainer);
// CREATE IMAGES CONTAINER //
var imagesContainer:MovieClip = new MovieClip();
imagesContainer.x=10;
imagesContainer.y=10;
addChild(imagesContainer);
//// LOAD XML ////
var xmlLoader:URLLoader = new URLLoader();
xmlLoader.addEventListener(Event.COMPLETE, whenLoaded);
xmlLoader.load(new URLRequest("XML/roiaXML.xml"));
var xml:XML;
function whenLoaded(evt:Event):void {
     xml=new XML(evt.target.data);
     var mySetsList:XMLList=xml.children();
     //// MENU BUTTONS ////
     // CREATE ARRAYS //
     var totalArray:Array = new Array();
     var setNodesArray:Array = new Array();
     var setNamesArray:Array = new Array();
     // POSITIONING BUTTONS INSIDE MENU CONTAINER//
     var rowsQuantity:Number=3;
     var columnsQuantity:Number=Math.ceil(mySetsList.length()/rowsQuantity);
     var cellWidth:Number=160;
     // CREATE BUTTONS //
     for (var i:int=0; i< mySetsList.length(); i++) {
          var newSetButtonMC:setButtonMC=new setButtonMC();
          //what do I do here to make it works? To give each button created a unique id.
          setNodesArray.push(i);
          //trace(setNodesArray);
          var imageNodesArray:Array = new Array();
          for (var j:int=0; j<mySetsList[i].IMAGE.length(); j++) {
               imageNodesArray.push(mySetsList[i].IMAGE[j].attribute("imageTitle"));
         nextSetButtonMC.imageArray = imageNodesArray;
          //totalArray.push(imageNodesArray);
          newSetButtonMC.setButtonText.text=mySetsList.attribute("galeriaTitle")[i];
          newSetButtonMC.setButtonText.autoSize=TextFieldAutoSize.LEFT;
          var cellX:Number=Math.floor(i/rowsQuantity);
          var cellY:Number=i%rowsQuantity;
          newSetButtonMC.x=cellX*cellWidth;

          newSetButtonMC.addEventListener(MouseEvent.CLICK, onClick);
          menuContainer.addChild(newSetButtonMC);
     totalArray.push(setNodesArray);
     //// MENU BUTTONS ACTIONS ////
     function onClick(mevt:MouseEvent):void {
          var mc:setButtonMC=setButtonMC(mevt.currentTarget);
for(i=0;i<mc.imageArray.length;i++){
trace(mc.imageArray[i]);

Dynamically creating buttons or hyperlinks

Hi all,
I am new to JSF and I am having some trouble. Hope you can help.
Situation: I have a database that contains contacts (i.e. names, addresses, telephone numbers, etc). I want to display a list of contacts in a table. For each item of this list I want a link in order to come to a detail screen of this item.
Creating a table that displays the names is no problem. However, the button (or hyperlink) seems to be problematic. I have looked in the archives and have found some people asking similar questions, but no alternative approach was really described. (See http://forum.java.sun.com/thread.jsp?forum=427&thread=448135) I am wondering what the best approach is at this moment in time.
Patrick

Roger,
Thanks for the suggestion. Unfortunatley, JSF does not do what you suggest. The id's that it generates are all the same.
Here is the jsf page:
<f:use_faces>
<h:form formName="form1" id="form1">
<h:panel_list id="contacts" >
<h:panel_data id="contact" var="contact" valueRef="searchDatabase.queryResult">
<h:command_hyperlink actionRef="searchDatabase.select" label="View Details" commandName="submit">
<f:parameter name="contactID" valueRef="contact.contactID" />
</h:command_hyperlink>
</h:panel_data>
</h:panel_list>
</h:form>
</f:use_faces>
And here is the resulting html:
<form method="post" action="/wc2/faces/protected/search_database_result_test.jsp">
<table border="0" cellspacing="0" cellpadding="6" >
<tr>
<td><a href="# onmousedown="document.forms[0.id0.value='submit'; document.forms[0].submit()">View Details</a><input type="hidden" name="id0"/><input type="hidden" name="contactID" value="1216"/></td>
</tr>
<tr>
<td><a href="#" onmousedown="document.forms[0].id0.value='submit'; document.forms[0].submit()">View Details</a><input type="hidden" name="id0"/><input type="hidden" name="contactID" value="1432"/></td>
</tr>
<tr>
<td><a href="#" onmousedown="document.forms[0].id0.value='submit'; document.forms[0].submit()">View Details</a><input type="hidden" name="id0"/><input type="hidden" name="contactID" value="1511"/></td>
</tr>
<tr>
<td><a href="#" onmousedown="document.forms[0].id0.value='submit'; document.forms[0].submit()">View Details</a><input type="hidden" name="id0"/><input type="hidden" name="contactID" value="2871"/></td>
</tr>
</table>
</form>
See the problem... all id's are the same, i.e. "id0".

Creating a Function logic for dynamically created XML buttons

Hi!
It's me...... again! Now I've dynamically created some buttons using XML. They're spread around the stage and I've modified a tooltip script to give each button a tooltip on Mouse_Over. But to se the logic and make it work using AS3 is hard (for me). I want a function that accept to parameters: Tooltip text and Object to tooltip.
In my code I get this error msg when initiating the function on dynamically created buttons:
1118: Implicit coercion of a value with static type flash.display:Sprite to a possibly unrelated type flash.display:MovieClip.
I beleive there are more than one thing here needing a fix.
Can someone have a look and give me a pointer?
Thanks
function contentTooltip(ttt:String, ttclip:MovieClip):void {
    ttclip.addEventListener(MouseEvent.MOUSE_OVER, mouseOverHandler);
    function mouseOverHandler(e:MouseEvent):void {
        ttip.descr.text=ttt;
        ttip.x=stage.mouseX;
        ttip.y=stage.mouseY-15;
        ttclip.addEventListener(MouseEvent.MOUSE_OUT, mouseOutHandler);
        ttclip.addEventListener(MouseEvent.MOUSE_MOVE, mouseMoveHandler);
        ttip.visible = true;
    function mouseOutHandler(e:MouseEvent):void {
        ttip.visible = false;
        ttclip.removeEventListener(MouseEvent.MOUSE_OUT, mouseOutHandler);
        ttclip.removeEventListener(MouseEvent.MOUSE_MOVE, mouseMoveHandler);
    function mouseMoveHandler(e:MouseEvent):void {
        ttip.x=stage.mouseX;
        ttip.y=stage.mouseY-15;
contentTooltip("Scale button",scale_btn);
contentTooltip("Hide button",hide_btn);

I totally agree with what Ned says and suggests. Nevertheless, I would like to support your thinking process.
From the way you wrote the tooltip functionality it is apparent to me that you conceptualize as a programmer. Again, as Ned said, nested functions are evil. BUT, in a way, what classes accomplish is encapsulation/nesting of properties and functions under the same umbrella. It actually feels that what timeline does in general is nesting named functions within a single function we have no access to.
How you wrote the code is actually a blueprint for a class that could handle the functionality. You, perhaps, are very ready to start coding with classes - not on the timeline.
With that said, for the sake of theory, here is how your functionality can be rewritten on timeline:
scale_btn.toolTip = "Scale button";
test_btn.toolTip = "Test button";
hide_btn.toolTip = "Hide button";
scale_btn.addEventListener(MouseEvent.MOUSE_OVER, mouseOverHandler);
test_btn.addEventListener(MouseEvent.MOUSE_OVER, mouseOverHandler);
hide_btn.addEventListener(MouseEvent.MOUSE_OVER, mouseOverHandler);
var overTarget:MovieClip;
function mouseOverHandler(e:MouseEvent):void {
     overTarget = e.currentTarget;
     ttip.descr.text = overTarget.toolTip;
     ttip.x = stage.mouseX;
     ttip.y = stage.mouseY - 15;
     overTarget.addEventListener(MouseEvent.MOUSE_OUT, mouseOutHandler);
     overTarget.addEventListener(MouseEvent.MOUSE_MOVE, mouseMoveHandler);
     setChildIndex(ttip, numChildren - 1);
     ttip.visible = true;
function mouseOutHandler(e:MouseEvent):void {
     ttip.visible = false;
     overTarget.removeEventListener(MouseEvent.MOUSE_OUT, mouseOutHandler);
     overTarget.removeEventListener(MouseEvent.MOUSE_MOVE, mouseMoveHandler);
function mouseMoveHandler(e:MouseEvent):void {
     TweenMax.to(ttip, .5, { x:stage.mouseX, ease:Quart.easeOut } );
     TweenMax.to(ttip, .5, { y:stage.mouseY - ttclip.height / 2, ease:Quart.easeOut } );
     //ttip.x=stage.mouseX;
     //ttip.y=stage.mouseY-ttclip.height/2;

I need to create Buttons dynamically Please Help

I am currently developing a card game. I represent my cards as buttons. But as the player draws more cards from the deck I have to generate buttons dynamically at run-time. I could use arrays of buttons and store new buttons inside that arrays of buttons. But the only problem is I need ActionListener for each of my buttons. How do you create ActionListener for each different dynamically created buttons? Please Help.

Scroll bars & creating buttons problem

I am trying to create a basic photo browser. The upper area is the enlarged view of the image. The lower portion is a scrollable view of the thumbnails in the directory chosen. I have most of it working...except that the scrollable view doesn't scroll, and the buttons that I created don't cause the image to show up in the main view port.
There is the main window, divided into two parts: upper and lower. The upper part is the main view, as described above. The lower part is a panel. That lower panel contains two things, another panel and a button. This panel inside the lower section contains the scrollable window; this scrollable window is a viewport onto another panel that contains the dynamically created buttons (which are thumbnails of the images in the directory).
I was trying to force the scrollbar policy to always show the horizontal bar (that is the only one I want visible) but that wasn't working either; I would get compiler errors when that was included. I have tried adjusting sizes of things, and the order that things are added to the main JFrame.
Any suggestions would be appreciated.
Here is the code:

* section for viewing the thumbnail previews. The lower section is also split into two parts: the left part
* is a scrollable pane where the thumbnails will be previewed, and then a small section to the right where
* a button for changing directories will be present. (I wanted the button to always be visible so didn't
* put it in the scrollable area.)

Ah! I got some of it figured out at least...
Setting the preferred size parameter has caused the scroll bars to display! :) Thanks for the hint on that.
But I get an error when I try and use the scrollbar policy settings. Here are the results:
Exception in thread "main" java.lang.IllegalArgumentException: invalid verticalScrollBarPolicy
     at javax.swing.JScrollPane.setVerticalScrollBarPolicy(Unknown Source)
     at javax.swing.JScrollPane.<init>(Unknown Source)
     at PhotoGUI.<init>(PhotoGUI.java:70)
     at PhotoBrowser.main(PhotoBrowser.java:15)And the code I used:
scroller = new JScrollPane(thumbs,
                    ScrollPaneConstants.HORIZONTAL_SCROLLBAR_ALWAYS,
                    ScrollPaneConstants.VERTICAL_SCROLLBAR_NEVER);       //Setting the scroll bar pane to view the thumbnail panel

Creating buttons dynamically in module pool screen

Hi friends,
I have one screen .
It has two input fields .
Say : Sales order no & Bin no .
based on this i found some batches from database table using select query .
Now the number of buttons depends on the no of batches i found .
If I get 5 batches , then I will create 5 Push Buttons on screen .
Please let me know , How to create these buttons dynamically on screen .
Regards ,
Manoj

Hey ,
I tried using custom container and then a toolbar in it .
But this toolbar create buttons either vertically OR horizonatally .
I want buttons all over the screen to be created dynmically .
Please help ...

Dynamically create varying number of buttons

Hi.
The website I'm currently working on has an object gallery.
Whenever the user clicks one of the objects, it zooms in and
displays a sub-gallery with other images of said object. The images
that make up these galleries are loaded into dynamically created
empty MovieClips inside a sub-gallery MovieClip. Each object has a
varying number of images and they're loaded and unloaded when the
zooming in/out of the object ends.
When you click one of the sub-gallery images, the main image
should change and display the clicked image. However, I'm having
trouble telling the MovieClips containing the sub-gallery images to
do anything when they're clicked. See attached code, please.
I'm guessing this has to do with the onRelease being declared
inside the onMotionFinished. The thing is I can't thing of a way to
declare the onRelease for every sub-gallery image before they're
loaded.
Thanks in advance.

Frank,
Thank you for the response.
On the page2 of the pdf link you provided there is a picture of the tree table and it shows the hierarchy of the first level(or root) parent (President, Steven King). If the data had n presidents (n first or root level ) then this will dispaly all data in the same tree table like
King
--Kochhar
----Greenberge
King 2
--report 1
----report 1.1
King n
--report n
----report n.1
My requirement is pretty close to this but slighly different where these n first level should appear in n different tree tables like below:
Treetable for: King
King
--Kochhar
----Greenberge
Treetable for: King 2
King 2
--report 1
----report 1.1
Treetable for: King n
King n
--report n
----report n.1
That is the reason why I am playing with af:forEach and also have a separate VO which returns all the presidents(first level parents) and view linked that to EmployeesVO so that the AM looks like
AllPresidentsVO
-----EmployeesVO (with the view criteria wihch returns the first level parents)
---------reportingManagers
forEach prints n instances for PresidentsVO King, King2.. King n but all these instances have the same children the tree for King (tree for King2 ... King n does not appear)
May be it should be achieved in a different way?

Is there a way to use a statically defined appearance stream in a dynamically created annotation?

Hello,
I want to create a document with cascading 'popups'. Not the built-in text-only popup, but an annotation containing an appearance stream that defines text and images. I'm currently using widget annotations based on a pushbutton field.
Each page in my document has many citations that refer to other pages in the document. When a user hovers over the citation, I want a 'popup' to appear containing a depiction of the destination. However, as the destination will itself have citations, I also want the 'popup' to contain citations that the user can hover over, triggering another popup, etc. In this way, a user could navigate throughout the document without leaving the page or even clicking the mouse.
Obviously, with even a modest number of citations per page, pre-calculating and statically defining all of these widgets causes a combinatorial explosion, making the document sluggish and very large.
Instead, I'd like to statically define appearance streams once per document, and then dynamically create annotations and assign the appropriate appearance stream using JS as the user navigates.
So far I've created a named AP in the names dictionary, but I haven't been able to use it to dynamically set an appearance stream of a dynamically created widget annotation.
Also, I've called Doc.getIcon(), passing in the named AP, which returns an Icon object. However, after field.buttonSetIcon() and passing in the named AP, the button does not display the icon.
Is there a way to use a statically defined appearance stream in a dynamically created annotation?
Thank you,
Dave

Hi George, I've gotten named APs to work, and I expect hidden buttons will follow. Thank you very much!
Quick follow-up - I will have many documents embedded within the same pdf file, and some of these documents will contain identical popups. However, I don't want to store identical icons in each document on account of file size.
Instead, I'd like to store one instance of each icon for all documents in the file.
Can I store all of the icons in a single document, and then access them by calling <DocName>.getField().getIcon() from any document in the file?
Thank you again,
Dave

Adding AJAX support for dynamically created panelGrid components

Hi everyone!
I would like to ask help from anyone who may have encountered similar problem before...
I have a panelGrid whose component is dynamically created by the backing bean. Here is my JSF code:
<h:panelGrid styleClass="panelGrid"
          rowClasses="tsPanelGridRowClass" columns="8" cellpadding="0"
          cellspacing="2" bgcolor="transparent" style="margin-left: 10px"
          id="revCenterItemPanelGrid"
          binding="#{pc_Touchscreen_pull_select_item.revCenterItemPanelGrid}">
</h:panelGrid>And here is the code for backing bean that adds content inside the panelGrid:
HtmlOutputText index = (HtmlOutputText) app.createComponent(HtmlOutputText.COMPONENT_TYPE);
index.setId("1");
index.setValue(String.valueOf(1));
index.setStyle("datagridtext");
revCenterItemPanelGrid.getChildren().add(index);On click of a button...
<a4j:commandButton value="Update"
          styleClass="commandExButtonPou2" id="button1" reRender="revCenterItemPanelGrid"
          actionListener="#{pc_Touchscreen_pull_select_item.doSortActionListener2}">
          <f:attribute name="order" value="2"></f:attribute>
          <f:attribute name="toggleState" value="off"></f:attribute>
</a4j:commandButton>the backing bean is supposed to update the value of the outputText
doSortActionListener2() {
HtmlOutputText index = (HtmlOutputText) app.createComponent(HtmlOutputText.COMPONENT_TYPE);
index.setId("2");
index.setValue(String.valueOf(2));
index.setStyle("datagridtext");
revCenterItemPanelGrid.getChildren().add(index);
}However, update doesn't seem to work. I have been successful in adding ajax support to a panelGrid that is not dynamically created but not for this one.
Has anyone encountered this error before? Any ideas?
Thanks in advance!
