Add element to GUI
Hi,
I was wondering if it would be possible to add new elements (eg button) to an app GUI (eg iTunes). I know how to do a script and make it available in scripts menu, but, is it possible to add a new button to the iTunes GUI, and fire the script when the user press this button?
I tried searching UI Scripting associate with some kind of skin/theme modification, but found nothing. I'm not restricted to scripting. Any tip/hint in any language/technology (preferably those compatible with OS X 10.8.x) is welcome.
TIA,
Bob
Whether or not you can add controls (or scripts) for an application is up to the developer - without the original source files you can't change an application.

Add element in dropdown list dynamically
Hi All,
I am facing a problem in adding item in a dropdown list dynamically.
When i get dropdown list through IgetElementById get null.
var list = document.getElementById("targetgroupname");
here list comes as null. Now I've to fill this list. I am using below code -
for(var j=0;j< com.length;j++){
iist.options[j]= new Option(com[j],com[j]);
But it is not working. My list is not getting filled with these values.
I doubt due to var list -> null it does not allow to add element.
But I am not getting any clue, how to initialize it.
Please suggest, I am new to javascript.
Thanks & Regards,
Sneha.Hi,
Thanks for the reply, yes the select box has that id - targetgroupname.
actually there are 2 dropdown lists, Based on the selection of first dropdown list another list shd be filled.
So I've written a script at "onchange" of first dropdown list. It works fine when a value gets changed at first dropdown list.
In some cases I've to display a preselected value at first list ( which comes from previous page as parameter), in that cases there will be no onchange on first list, so I've called the script function manually after creating the first list,like below :
<SCRIPT> checkSource();</SCRIPT>
and in this case it does not work & I get a null when i try to read the 2nd list.
But I am not sure why it is happening.. may be it is not loaded /created on page when i am calling it.
If yes, what shd I do ?
Thanks for your time.

Is there a way you can add elements dynamically to an existing array??
hey guys... i need to add elements to an array dynamically... how do i do that?
for example... in one of my functions i do..
for each(var item:Object in fileList){
fileListArr.push(item);
and in a later function i need to add one more element to my fileListArr...
so i tried doing
fileListArr[indexNum].push({
key:videoKey
so i need to have an array which resembles something like this...
Before adding elements...
fileListArr:
[0]: name:test1
Size:12K
caption:testing caption
number:1
[1]: name:test2
Size:12K
caption:testing caption
number:2
after adding key to array
fileListArr:
[0]: name:test1
Size:12K
caption:testing caption
number:1
key:xyxyyy11y1yy1y1y2y2u33n
[1]: name:test2
Size:12K
caption:testing caption
number:2
key:iiduudjmenri112jj2n4n3m2j1j21
any ideas?hmm interesting... so i made the changes... i changed the array to arraylist and the code i have is as follows... but i still get an error... the error says ... "ReferenceError: Error #1056: Cannot create property key on flash.net.FileReference."

How to add elements into Object[][] type of list, in runtime?
I have Object list, ie.
final Object[][] data = {
{"January", new Integer(150) },
{"February", new Integer(500) },
{"March", new Integer(54) },
{"April", new Integer(-50) }
};How can I dynamicly add new elements in it, at the runtime?
Thank you in advance!Do I have to remove 'final' for that, and then add
elements?
No. you can't change an array's size.
You can do this
Object[][] arr = new Object[numRows][numCols];But once you've created it, its size can't change.*
I don't know what you're doing, though, and what actual data you're putting in, but Object[][] holding rows of [String, Integer] is almost certainly a poor data structure. Think about creating a class the represents one "row" here and then create a 1D array of that class.
* Okay, you can kinda sorta effectively "change" the size of second and subsequent dimensions, since a multidimensional array is an array of arrays. I wouldn't recommend it though: int[][] arr = new int[3][2]; // a 3 x 2 rectangular array of int--it's an array of array of int, with 3 "rows", each of which is an array of int with 2 elements.
arr[0] = new int[10]; // now it's a jagged array whose first row has 10 elments instead of 2Here we haven't changed an array's size, just replaced one of its elements, which is also an array, with a new, larger array. -

Hello!
I'm just beginning and can't understand one thing:
When I create JSPDynPage, system create JSP and JAVA file - it's clear. Then I add elements to form in JSP, for example, Layout.
Can I add, for example, row into that Layout in .java file?
.JSP:
<hbj:form>
<hbj:formLayout
id="myLayout"
width="100%">
<hbj:formLayoutRow
id="Row1">
<hbj:formLayoutCell
id="Cell11"
align="LEFT"
width="100%">
<hbj:textView
id="welcome_message"
text="May the force be with you unknown user"
design="HEADER1" />
</hbj:formLayoutCell>
</hbj:formLayoutRow>
</hbj:formLayout>
</hbj:form>
.JAVA:
public void doProcessBeforeOutput() throws PageException {
this.setJspName("myjsp.jsp");
Form Reg_Form = null;
FormLayout RF_All = new FormLayout();
Tray Left_Tray1 = new Tray("TrayRules1");
Reg_Form = (Form)this.getForm();
RF_All = (FormLayout) this.getComponentByName("myLayout");
for (int i = 1; i <= 3; i++ ) { RF_All.addRow(); }
Left_Tray1.setTitle("Sample Title");
Left_Tray1.setWidth("100%");
TextView Left_Tray1_text = new TextView("Left_Tray1_text");
Left_Tray1_text.setText("Sample Text");
Left_Tray1_text.setEncode(false);
Left_Tray1_text.setWrapping(true);
Left_Tray1.addComponent(Left_Tray1_text);
RF_All.addComponent(2,1, Left_Tray1);
Reg_Form.addComponent(RF_All);
That code don't display Tray in page...Paul,
I suggest you not to add the your business logic in that auto generated file.
Instead you can have seperate java file or any Bean.
Since you are writing the logic for layout you can add the code in the jsp file
itself.
If you are using HTMLB Then keep the auto generated code in the jsp otherwise remove the code and keep the file as jsp meaning you use the html, javascript,
jsp code in the .jsp file itself.
you can add the java code in the jsp
<% String strName = "SAP"; %>
<sc ript>
al ert("<%=strName%>");
</sc ript>

GeneralException Node(( Context path of node ): cannot bind or add element,
Hello all,
Stack trace :
GeneralException Node((<Context path of node>): cannot bind or add element, because it is already bound to a node
I am trying to upload data from excel file in web dynpro context.In the process, when I create and add an element to the node which I want to populate with excel data, it throws the above mentioned exception.
Any idea as to wht is causing the problem ?Hi,
GeneralException Node((<Context path of node>): cannot bind or add element, because it is already bound to a node
It seems that its a mapped node, try to bind or addelements at the source.
Ex: If this node is mapped from controller to view try to add elements in contoller instead of doing in view.

ContextException : cannot bind or add element
Hi all,
I can't find an answer to my problem.
Hope you'll be able to
Here are the facts :
Context :
I'm currently creating a TeamViewer for Managers to be able to select the employees they manage.
For that, I have a table which lists them all, displaying their infos in specific columns.
Both columns and data are dynamic and are specified in the SAP back end.
I use the following bapis to get these informations :
- HRWPC_RFC_GET_COL_INFO (returns columns informations)
- HRWPC_RFC_GET_OBJECTS (returns employees personal numbers -> pernr)
Fact is the second one doesn't return as much informations as needed.
So I have then to call a third bapi :
- MYBAPI_USER_INFOS (return informations about an employee)
which, from an employee pernr, returns a lot more informations about him.
Fact is I manage to use efficiently both first bapis, so I get columns and pernr data.
Then I would like to get in a context node the list of enhanced informations of the employees, which is mapped to my view context and applied to a dynamic table.
My problem :
While adding programmaticaly the columns to my context node, I get the following exception : "com.sap.tc.webdynpro.progmodel.context.ContextException: Node(TeamViewerApp.MainViewColumns): cannot bind or add element, because it is already bound to a node" error.

AlphonseHI,
com.sap.tc.webdynpro.progmodel.context.ContextException: Node(HrChiefRedressalView.Ctx_FilteredOutput): cannot bind or add element, because it is already bound to a node
Try to bind or add element from the source of the node instead of mapped one.
Ex:
Controller->View
If your node is mapped from controller to view. bind/add element should be done at controller level not at view level.

Add element in to bundle/unbundle Functions

Hi guys,
I am adding elements to the gui like this:
var myText = win.add("edittext", undefined, "whatever");
Later in my code I need to remove this element from UI. Is it possible?Use the remove() method: win.remove(myText);
In general: container.remove(child);
You can add it later later but then, if you use the autolayout, you'll need to relayout: win.layout.layout(true) otherwise it won't show up -
Hi All,
I am trying a add an element (to the individual/lowest level) in my existing report in 'GRR2'.

I can't find a single example on the internet that does anything like what I'm doing that I can use as a reference. I need something using radio buttons that calculates another number based on the results of the radio buttons...like what mine should do.
This has got to be a noob question, but I just can't get it to work....
