How To Update Custom ItemRenderer (Image) on DataGrid Edit
I have an DataGrid with 2 columns, column 1 called "Name" and column 2 called "Actions".
The "Name" column contains editable text and the "Actions" column uses a (inline) custom ItemRenderer which displays 2 icon images ( for Edit and Delete). All works fine. Clicking Edit or Delete calls the corrosponding outerDocument method.
The feature I am trying to add is as follows: when someone double-clicks on the text in the Name column to edit it, I would like the edit icon in the Actions column to ( grow/shrink, change color - or some such indication/reminder to click it ). Not seeing how to do this with the inline ItemRenderer, I created a custom item renderer class and, in that class, use mx:Resize to perform the "grow/shrink". I created a method called "pulse()" and, from within that renderer, all works well. ( for testing, I wired the icons click event to the pulse() method ). However, now I am not sure how to call that ItemRenderers "pulse()" method to perform the effect from the main DataGrid (when the user double-clicks on Name field to edit).
The tried using the DataGrid's "itemEditBegin", which fires correctly, but from that point I am not sure how to access the selected rows edit icon in the "Action" column. ( to call its pulse() ) method.
So any suggestions how I can achieve my end result? Being able to manipulate the edit icon in the "Actions" column, when the user double-clicks (edits) that row's "Name" column?
If I'm going about it all wrong, feel free to offer alternative solutions.
Any help would be appreciated.
Thanks,

Hi,
Check the BAPI_MATERIAL_SAVEDATA ,in the BAPI is there a table parameter EXTENSIONIN ?
which you can use to pass the values for user defined fields to the BAPI..

How to update the ItemRenderer at runtime..?
Hi....
am facing a hectic problem with ITemRenderes..
My requirement is like i need to insert a Label and Image in
each item of Horizontal List.
For this i created a ArrayCollection with Lable and
ImagePath. And assigning array as a Dataprovider to HorizontalList.
and am attaching itemrenderer to it (which hold the lable and
image).
code:
var data:ArrayCollection=new ArrayCollection({label:'A',
path:'a.jpg'}, {label:'B', path:'b.jpg'}{label:'C', path:'c.jpg'});
var hList:HorizontalList=new HorizontalList();
hList.dataProvider=data;
hList.itemRenderer=new ClassFactory(rendererObj);
rendererObj holds the Lable Component and Image Componnet..
Now the porblem is am trying to change the horizontal list at
runtime. Like i want to change the lable of selected item in
Horizontal list. Am able to update the arraycollection values. But
its not getting effected in ItemRenderer.

See how that works..you press the button and the itemrenderer
gets drawn into the horiz. list with the values from the

I didnt implement the picture, but you get the idea on how to
get
the values into the hlist..

IS-RETAIL: How to update custom enhancement field using BAPI?
Hi gurus,
Like ECC BAPI: BAPI_MATERIAL_SAVEDATA,
This BAPI(BAPI_MATERIAL_MAINTAINDATA_RT) is specific for IS-RETAIL to create and update material master data.
But now If I append one custom field "ZFIELD" to end of table MARA, my question is how to update this custom enhancement field(ZFIELD) using BAPI(BAPI_MATERIAL_MAINTAINDATA_RT)
Thanks in advance!Hi DongHai,
I suggest you create your own BAPI. Just copy the codes in BAPI_MATERIAL_MAINTAINDATA_RT and add your custom fields. If you want to append the data of the custom field in table MARA, first, you have to create a structure table then goto SE11, type MARA and display. Click the APPEND STRUCTURE then choose the structure that you've created. Hope this will help.

How should a custom cursor image be constructed?
This relates to Java 1.7_u11 and JFX 2.2.4 on Windows 7 64 bit.
When I set a Node's cursor to Cursor.CROSSHAIR, the crosshair is displayed with complementary colour to its screen background (e.g. black on white, blue on yellow, etc.) However when I construct my own custom crosshair image, 32 pixels square, with transparent-white background pixels and opaque-black crosshair pixels, and create an ImageCursor from it to use as the cursor, it works fine, but always displays as black, irrespective of the background that it's being displayed over. I've tried various ways of creating the image.
So my question is, is there something special about the built-in Cursor images, and how should we emulate it for an ImageCursor? More generally, how does the 'blend mode' for cursor images work?
(Apologies if I'm displaying dismaying ignorance here.)Hrm, I tried Crosshair on my Linux computer with different background fills in Scene and didn't notice any change in color. It was always a cross with white fill and black outline. I wonder if the appearance of certain cursors are OS specific.
Anyways, I don't see anything in the documentation to set that. If you want a more customizable cursor, submit an RFE to http://javafx-jira.kenai.com/ -
Setting a DataProvider to a custom itemRenderer in a DataGrid
Hi,
I've got a DataGrid, with one column using a custom AS itemRenderer to display a ComboBox. Everything works, but there are various "wierd" behaviors occuring (when I remove a row, the ComboBox of the next row in line resets to it's label, but none of the others do... When I add a row, various apparently random comboboxes change their selectedItem, etc...)
Anyways, I had some luck isolating each of these individual bugs and squashing them, but each time I do, others seem to pop up. I suspect the main issue is the way I'm setting the ComboBox's dataProvider. The dataProvider is dynamic - an XML file generated from a MySQL table using PHP. Knowing no other way to do so, I'm overriding the set data method and explicitly setting it there, like so:
override public function set data(value:Object):void{
super.data = value;
dataProvider = value.uom; // value.uom is the XML
Is there a better way to set the data provider - an approach where I can set it once and therefor avoid the override entirely? Again, the itemRenderer is an ActionScript class, and not implemented with XML...
<mx:DataGridColumn itemRenderer="renderers.UOMBox" dataField="uom" headerText="UOM" />
and...
package renderers{
public class UOMBox extends ComboBox{
... etc ...
Thanks in advance.How does this code work for you:
override public function set data(value:Object):void{
if(value != null) {
super.data = value;
dataProvider = value.uom; // value.uom is the XML
super.invalidateDisplayList();
The missing invalidateDisplayList in your code might be what will help with your problems.

Flex datagrid custom itemRenderer - making column NOT EDITABLE
Hi all,
I am new to flex and having been trying to build custom editors and renderers for datagrid. I ran into this problem trying to fix another one (http://forums.adobe.com/post!reply.jspa?message=3569216)
The problem is :
I have a custom editor and a renderer for a text column. The whole grid is editable (i.e; editable=true). But clicking on the cell does not show me the editor. However, if I change the renderer to mx.controls.label, clicking on it takes me to my custom editor.
Can anyone please tell what I am doing wrong?? I am pasting the relevant code for more details.

Tricks I have tried and failed :
1. added the following code to the renderer
override public function get data():Object{
return super.data;
2. remove/change focusEnabled
3. wrote the same renderer in Actionscript - making it extend MXDataGridItemRenderer. I had to add the label component txt using addElement. Clicking on this does show th editor but it doesnt show the label txt at all... i.e; I dont get any text displayed.
I am using Flex 4.0 sdk.It worked!!!!!!! Thank you!! What you mentioned was indeed the problem!
Here is the custom item renderer's set data function
Before
Now
override public function set data(value : Object):void{
super.data = text;
this.txt.text = (value as Slide).text ; //txt is the Label control
override public function set data(value : Object):void{
super.data = value;
this.txt.text = (value as Slide).text ; //txt is the Label control
oh man, this is such a stupid mistake. I think I was confused with having three text properties - one inherited from MXDataGridItemRenderer, one in my txt Label control and one on my slide.
I had no idea that sending the value up to the super class was so important. None of the docs I read seemed to give much importance to this statement.
thanks so much and sorry for taking up so much of your time. I guess it is uncessary to post any more code. -
How to bind an itemRenderer to a datagrid
I have a datagrid that uses an itemRenderer. The itemRenderer contains a checkbox. I want the selected checkbox in the datagrid to stay in the correct row when the datagrid is sorted, but when I sort a column the checkbox moves to the wrong row. How do I bind the checkBox to the datagrid? I tried playing around with the following 2 lines of code in the itemRenderer, but without success:
//super.data = value;
//dispatchEvent(new FlexEvent(FlexEvent.DATA_CHANGE));

How to update previously modified Image and prevent from reverting?
Below is my code for updating a painComponent:- it basically zooms in on a particular image. The zooming works for the first try. But since the Image ITSELF isnt updated if i try to zoom in on the zoomed image its actually trying to zoom the original image since my g.drawImage() has the original Image (not zoomed). Is there anyway to update the Image so that it is the previously zoomed image and not the original? I searched for "zoom" throughout the boards and no one seemed to brough this "problem" up. Can someone help me out? thanks
public void paintComponent(Graphics g) {
g.drawImage(zoomingImage,0,0,(int)zoomFrame.getWidth(),(int)zoomFrame.getHeight(),((Point) zoomStartPoints.lastElement()).x,((Point) zoomStartPoints.lastElement()).y,((Point)zoomEndPoints.lastElement()).x,((Point) zoomEndPoints.lastElement()).y,Color.WHITE,null);}
setOpaque( false ); // background will not be painted by super.paintComponent()
if (startPoint != null && endPoint != null) {
int x = Math.min(startPoint.x, endPoint.x);
int y = Math.min(startPoint.y, endPoint.y);
int width = Math.abs(endPoint.x - startPoint.x);
int height = Math.abs(endPoint.y - startPoint.y);
g.drawRect(x, y, width, height);

How to update custom metadata?
Hi,
I have created a xml document (schema based) in the repository.
I append with appendResourceMetadata a xml document (also schema based)
Now I try to change an element value of the metadata with the folowing update command but the value do not change. Why? What is wrong?
a) update resource_view set res = updateXML(res,'//CMSWorkflow/State/text()','submitted','xmlns="http://xmlns.oracle.com/xdb/CMSWorkflow"') where any_path = '/siecom/Australia/CCMIGhtml_test.xml'
b) update resource_view set res = updateXML(res,'/r:Resource/CMSWorkflow/State/text()','submitted','xmlns:r="http://xmlns.oracle.com/xdb/XDBResource.xsd"') where any_path = '/siecom/Australia/CCMIGhtml_test.xml'
c) update resource_view set res = updateXML(res,'/r:Resource/w:CMSWorkflow/w:State/text()','submitted','xmlns:r="http://xmlns.oracle.com/xdb/XDBResource.xsd" xmlns:w="http://xmlns.oracle.com/xdb/CMSWorkflow"') where any_path = '/siecom/Australia/CCMIGhtml_test.xml'
Any help are realy welcome.
Note: if I update with updateResourceMetadata it works, but this meen to update the full document not only one element!

User - exit for STKO table (PCSD0003). How to update customer field.
Hello,
I made a user - exit for STKO table.
It works like a formula field - calculate total weights of the specification components.
But there is a problem!
When I add new components into my specification or change them, my customer field is now calculated.
I always need to click a Customer tag and explode a user subscreen. Is there any way to sort the problem out?
I want to recalculate my customer field every time I change components?Hi,
There is a specific user-exit for delivery-creation/delivery processing/change delivery status.
the program name is MV50AFZ1. Inside this exit, there is a particular sub-routine called as
FORM USEREXIT_MOVE_FIELD_TO_LIPS.
endform.
May be probably you can try this. This also needs an access key for changing the SAP standard program.
Another way is you can use the BADI : LE_SHP_DELIVERY_PROC
This BADI influences processing of delivery data, during creation and changing of deliveries at specific points described in the interface. The BAdI methods enable you to read, write, determine, delete, and save your own delivery-related data, and to change the standard delivery data.

If I assign custom ItemRenderer to a DataGrid, this also affects headers, i.e. headers start looking as the fields in a grid. Not only that, but it seems that render is much worse and it really looks bad. Is this how it's supposed to be, is there a workaround to keep the headers as they should be and just change the actual renderers in the grid?
Post a bit of your code.
Sincerely,
Michael

Conditional Image from DataGrid Value
Hi all,
Using a custom itemRenderer within my DataGrid, I've been
able to add an image. (see code below) Now my problem is this...
How does one go about setting the source of the image based on a
value within the corresponding data. In my case, the value of the
attribute "status" may be either "OK" or "Unreachable", and I want
to control the source of the image based on which one is set. How
would one do such a thing?
<mx:DataGridColumn headerText="" dataField="status"
width="30" resizable="false">
<mx:itemRenderer >
<mx:Component>
<mx:HBox>
<mx:Spacer/>
<mx:Image source="image/ok.png" />
<mx:Spacer/>
</mx:HBox>
</mx:Component>
</mx:itemRenderer>
</mx:DataGridColumn>You can write a custom itemRenderer in MXML that overrides
the set data function. Your renderer would look something like
this:
<mx:HBox xmlns:mx="
http://www.adobe.com/2006/mxml"
>
<mx:Script>
<![CDATA[
override public function set data(value:Object):void
if(value != null)
super.data = value;
if (value.status == "OK")
img.source = "ok,jpg";
else
img.source = "unreachable.png";
]]>
</mx:Script>
<mx:Spacer/>
<mx:Image id="img" source="image/ok.png" />
<mx:Spacer/>
</mx:HBox>
Then, you would just have:
<mx:DataGridColumn headerText="" dataField="status"
width="30" resizable="false" itemRenderer="myCustomRenderer" />
I hope this helps.
