Datagrid hScrollPolicy problem with cellRenderer

Hi all, I'm having a problem which I can't seem to solve. I'm using a cellRenderer to display icons in a dataGrid. All works fine until I type in the command myDg.hScrollPolicy = "auto". Once I issue that command, the icons stop displaying. If I remove that line, all works well once more. Has anyone had this strange behaviour?

Not real sure. The components in AS2 are very strange. I didn't encounter that one before it was just a guess based on their pickiness(if that's a word). The AS3 components seem to be a major upgrade. I actually just built most of my components myself for AS2. They were light weight and easy to customize, however the datagrid is very difficult. Good luck!

Display Problems with CellRenderer for JList and JRE 1.2.2

I'm using a CellRenderer to handle a JList as below. The problem is that with the JRE 1.2.2, I'm getting bizarre artifacts like choosing an item in the list and having every item above it go bold, then choosing another item in the list and having all items go unbold. This works fine with the JDK, but when run with the JRE the cell renderer goes amok. Any suggestions? Could it just be my card? (the Matrox G400 Max is documented to have Java display problems) or did I miss something in the class? Thanks.
class EB_ListCellRenderer extends JLabel implements ListCellRenderer, EditorConstants{
private final String[] text;
private Font plain = new Font("Arial",Font.PLAIN,12);
private Font bold = new Font("Arial",Font.BOLD,12);
public EB_ListCellRenderer(String[] text) {
     this.text = text;
public Component getListCellRendererComponent(JList list,Object value, int index,boolean isSelected,boolean cellHasFocus)
     setText(text[index]);
     setEnabled(true);
     setOpaque(true);
     setForeground(FOREGROUND);
     if (isSelected) {
     setFont(bold);
setBackground(SELECTED);//color
     } else {
     setFont(plain);
     setBackground(UNSELECTED);
     return this;

I found a solution for Matox Gxx cards. If you lower the hardware accelleration down one notch, it will most likely help you to display java gui's correctly.
Hope this helps.

DataGrid highilght problem with ItemRendered Text

I have a datagrid with some elements that are defined as
using an itemrenderer:
<mx:DataGrid id="dg" dataProvider="{dp}" >
<mx:columns>
<mx:DataGridColumn headerText="header"
dataField="element" itemRenderer="dgRenderer" />
Now, the item renderer just lists what text should be there:
override public function set data(value:Object):void
this.text = "new text";
So, as far as it goes, this works fine (all app-specific
stuff ripped out, but you get the idea). The text does show up in
the datagrid correctly. However, when I mouse over the datagrid,
normal (i.e. not-item-rendered) items get a dark background, and
change their font to a gray color. However, item-rendered objects
appear in black text, always.
Does anyone know why that is, or how I can solve it?
Thanks for any help you can provide.

Here are some options:
1) Just use a labelFunction
2) Extend the default itemRenderer
3) Look at the code for the default itemRenderer and see how
it handles

Problem with CellRenderer

Hi everybody.
Look at this piece of code:
package graphics;
import javax.swing.*;
import javax.swing.table.*;
import java.awt.*;
import java.util.*;
public class EssaiJTable extends JTable {
 /** Creates a new instance of EssaiJTable */
 public EssaiJTable() {

 for(Enumeration e = this.getColumnModel().getColumns(); e.hasMoreElements();) {
 TableColumn column = (TableColumn) e.nextElement();
 column.setCellRenderer(new MyCellRenderer());
 private class MyCellRenderer extends JLabel implements TableCellRenderer {
 public MyCellRenderer() {
 this.setHorizontalAlignment(SwingConstants.CENTER);
 public java.awt.Component getTableCellRendererComponent(JTable jTable, Object value, boolean isSelected, boolean hasFocus, int row, int column) {
 if(isSelected) this.setBackground(new Color(0x49aba6));
 else this.setBackground(Color.WHITE);

This code works fine fine, i mean the content of the cells appears in the center of the CellRenderer (my CellRenderer).

Why ???????????
Please help me.

According to the JLabel api:
public void setHorizontalAlignment(int alignment)Sets the alignment of the label's contents along the X axis.
This is a JavaBeans bound property.
Parameters:
alignment - One of the following constants defined in SwingConstants: LEFT, CENTER (the default for image-only labels), RIGHT, LEADING (the default for text-only labels) or TRAILING.
See Also:
SwingConstants, getHorizontalAlignment()
public void setHorizontalTextPosition(int textPosition)Sets the horizontal position of the label's text, relative to its image.
Parameters:
textPosition - One of the following constants defined in SwingConstants: LEFT, CENTER, RIGHT, LEADING, or TRAILING (the default).
Throws:
IllegalArgumentException

Problem with checkbox item renderer in datagrid

I have a data grid having check box as an item renderer. I have viewed many posts in this forum but nothing useful in my case. I am failed to bind my datagrid itemrenderer checkbox with the field of dataprovider i.e. listUnitMovement.CHECK_PATH. Then I have to traverse data provider to check which checkboxes are checked.
[Bindable]
var listUnitMovement:XMLList=null;
In a function call
public function init(event:ResultEvent):void
 listUnitMovement=event.result.unitmovement;
 <mx:DataGrid id="dg_country"
 dataProvider="{listUnitMovement}"
 enabled="true">
 <mx:columns>
 <mx:DataGridColumn>
 <mx:itemRenderer>
 <mx:Component>
 <mx:CheckBox selectedField="CHECK_PATH" />
 </mx:Component>
 </mx:itemRenderer>
 </mx:DataGridColumn>

 <mx:itemRenderer>
 <mx:Component>
 <mx:Button label="Details"/>
 </mx:Component>
 </mx:itemRenderer>
 </mx:DataGridColumn>
 </mx:columns>
 </mx:DataGrid>

Hi,
Do you want to just check/uncheck the checkboxes based on the CHECK_PATH field.
Do you want something like this...
<?xml version="1.0" encoding="utf-8"?><mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute">
<mx:Script>
<![CDATA[

</mx:Script>
<mx:DataGrid dataProvider="{listUnitMovement}">
<mx:columns>
<mx:DataGridColumn>
<mx:itemRenderer>

</mx:itemRenderer>
</mx:DataGridColumn>
<mx:DataGridColumn dataField="NEW_LAT"/>
<mx:DataGridColumn dataField="NEW_LONG"/>
</mx:columns>
</mx:DataGrid>

Please let me know clearly what's your problem...Do you want to just bind the check box based on XmlList or something else..?

Having problem with change of name in the datagrid Coding

I am having problem with changing the name of the datagrid header text name for one of the data either in the flash file or the php file.
The thing is i want to change the Course_Name to Course Name that has no underscore so that it will look nicer in the datagrid but if I change it in the php file like SELECT Course_Name as 'Course Name' ....., it will not turn out in the datagrid when I CTRL ENTER the flash file but the others like Price,description and display is shown.
There is no problem with my php code but I do not know how to change the Course_Name into Course Name so please help me resolve this error that I am having.
This is my flash code
function goCourse(e : MouseEvent):void
gotoAndStop(5);
refreshResponder = new Responder (refreshSuccess, onFault);
connection = new NetConnection ();
connection.connect (gateway);
dataDG.addEventListener (Event.CHANGE, gridItemSelected);
refreshData (true);
function gridItemSelected (e: Event): void {
ID = e.target.selectedItem.ID;
courseTxt.text = e.target.selectedItem.Course_Name;
priceTxt.text = e.target.selectedItem.Price;
descTxt.text = e.target.selectedItem.Description;
private function getParams () {
var param: Object = new Object ();
param.ID = ID;
param.Course_Name = courseTxt.text;
param.Price = priceTxt.text;
param.Description = descTxt.text;
return param;
private function refreshData (refresh: Boolean): void {
if (refresh)
connection.call ("Course.viewCourse", refreshResponder);
private function refreshSuccess (result: Object): void {
dataDG.dataProvider = RecordSetDP.toDataProvider (result);
dataDG.columns = ["Course_Name","Price","Description","Display"];
private function onFault (fault: Object): void {
trace (String (fault.description));
This is my php file code.
function viewCourse()
$this->connect();
$sql = "SELECT Course_Name,Price,Description,Display
FROM coursetb";
return mysql_query($sql,$this->_connection);

i don't see where you're calling your php file in your code, but change 'Course Name' to 'Course_Name' (or vice-versa) there.

Problem with datagrid horizontal scrollbar

Hi all,
I am facing problem with Datagrid HorizontalScrollBar.
As per requirement i need to seperate the Horizontal and verticalscroll bars from grid.
So what i did was, i created HScroll & VScroll components and associated them Datagrid scroll bars. I made HorizontalScrollPolicy and VerticalScrollPolicy "off" for datagrid.
As i binded values to HScroll & VScroll components which are out side of datagrid, i should be able to scroll datagrid using those components.
Its working fine for VScroll. When i scroll VScroll component am able to scroll datagrid vertically.
Problem is with HorizontalScrollPolicy in datagrid, when i change the policy to "on" i can see the scrollbar down to datagrid and able to scroll. once i change the policy to "off", datagrid columns are getting resized and datagrid width will set back to its container width without scrollbar, because of this there will be no HorizontalBar for datagrid to assiciate with HSCroll Component.
Code given below:
[AS]
private function vScrollGrid(event:ScrollEvent):void
mainTable.verticalScrollPosition=vScrollBar.scrollPosition;
private function hScrollGrid(event:ScrollEvent):void
mainTable.horizontalScrollPosition=hScrollBar.scrollPosition;
}[/AS]
[CODE]
<mx:HBox height="100%" verticalScrollPolicy="off" horizontalScrollPolicy="off">
 <mx:DataGrid dataProvider="{reportData}"
 id="mainTable"
 height="100%"
 width="100%"
 textAlign="right" allowMultipleSelection="true" visible="false" verticalScrollPolicy="off" horizontalScrollPolicy="off"/>
 <mx:VScrollBar id="vScrollBar" height="100%" pageSize="1" scrollPosition="{mainTable.verticalScrollPosition}" maxScrollPosition="{mainTable.maxVerticalScrollPosition}" scroll="vScrollGrid(event)"/>
</mx:HBox>
<mx:HScrollBar id="hScrollBar" height="100%" pageSize="1" scrollPosition="{mainTable.horizontalScrollPosition}" maxScrollPosition="{mainTable.maxHorizontalScrollPosition}" scroll="hScrollGrid(event)"/>
[/CODE]
Please help me to resolve this
Thanks & Regards

1. Try calling setEnabled(true); on the scrollbar
2. Check that you need to scroll. If efffectively the knob (as the API docs call it) is larger than the scrollbar, it probably won't be shown.

Problem Module/datagrid, one time with data, one time is null

Hello All
thanks for this discussion place, i have a problem in Flash Builder 4.6 (sdk 4.6.0), construct an application who connect to DB, for now, the CRUD works fine with flex service,
i have a problem with a datagrid, one time it's worked fine, and another time my obj is null, i cannot understand why.. the fact it's work one time trouble me.. and i have no error in console..
the target, is to edit a row of datagrid in popup, it's work as you stay in the ModuleClient, but when i launch another Module and come back to ModuleClient, the edit datagrid doesn't work anymore
i try to put the process here, as the app is large: (say to me if you want more code, i will try to isolate some pieces)
- click in ModuleMenu and load ModuleClient in ModuleContent
- dataGrid populate with ArrayCollection
- double click row in dataGrid (dataGrid_doubleClickHandler(event:MouseEvent))
- dataGridClients.selectedItem contains effective data
- push data to ValueObject (ClientObj) already defined in flex services/connected to DB
 var ClientDataGrid:ClientObj = dataGridClients.selectedItem as ClientObj;
- push data ClientDataGrid to Popup
 in Popup: <valueObjects:ClientObj id="clientObj"/>
- works fine
if i select another Module in ModuleMenu, and later relaunch ModuleClient
- dataGrid populate with ArrayCollection
- double click row in dataGrid
- dataGridClients.selectedItem contains effective data
- push data to ValueObject (ClientObj) already defined in flex services/connected to DB
 var ClientDataGrid:ClientObj = dataGridClients.selectedItem as ClientObj;
- ClientDataGrid is null
- cannot push data ClientDataGrid to Popup as ClientDataGrid is null
- doesn’t work

Thanks in advance for any advices/ideas
i think i make misunderstood of something, im not a flex/flash as3 coder
so any help would be greatly appreciated
best regards anyway

thanks Alex for your link, i read it carrefully, i have to study some thing imo
but, i don't find solution for now, otherwise, i found a strangely similar problem here : it's seem to be the same problem as i have :
https://issues.apache.org/jira/browse/FLEX-18680 [After Module reload dataGrid.selectedItem as MyClass NOT WORKING]
do you think i encounter a bug?
(i will try to isolate some code to test more)
thanks again for advices/ideas

Problems with DataGrid and WordWrap

Hi all,
I have some problem with the headerText property of the
mx:DataGridColumn, when the text is longer than the column width.
Even if I set headerWordWrap property to true, sometimes the text
shown in the header is truncated.
The behaviour is strange: if you change the column width
moving the mouse, sometimes the text is truncated and other times
it isn't.
Can somebody help me or confirm that it is a Flex bug, please
thanks
cheers,

Tab with Cellrenderer and Combobox

When using Cellrenderer to display a combobox in a datagrid, there is an issue with using Tab. If you tab through the cells, it will cause the combobox to erase. To fix this the column needs to be set to non-editable. Problem with doing this is that then you cannot tab to the cell where the combobox is.
Does anyone know a work-around this?

Had you RTFA you would have learnt that JTable uses Renderers in the same way you would use a
rubber stamp... thus each header is NOT a seperate Component, but the same component simply
used to paint it....
Following on from this... you may have now what looks very much like an active combo box, this is
just fooling you. It is merely a ghost of a combo box.. some pixels on the screen, nothing more..
First and foremost, before running around in desperate circles - RTFA

Problem with the MenuBar and how can i delete a own component out of the storage

Hello,
I opened this thread in the category "Flex Builder 2", but
under this category my questions fit better.
I have a problem with the MenuBar and a question to delete a
component out of storage.
1. We have implemented the MenuBar, which was filled
dynamically with XML data.
Sporadically it will appear following fault, if we "mousover"
the root layer.
RangeError: Error #2006: Der angegebene Index liegt
außerhalb des zulässigen Bereichs.
at flash.display::DisplayObjectContainer/addChildAt()
at mx.managers::SystemManager/
http://www.adobe.com/2006/flex/mx/internal::rawChildren_addChildAt()
at mx.managers::SystemManager/addChild()
at mx.managers::PopUpManager$/addPopUp()
at mx.controls::Menu/show()
at mx.controls::MenuBar/::showMenu()
at mx.controls::MenuBar/::mouseOverHandler()
Here a abrid ged version of our XML to create the MenuBar:
<Menuebar>
<menu label="Artikel">
<menu label="Artikel anlegen" data="new_article" />
<menu label="Artikel bearbeiten" data="edit_article" />
<menu label="Verpackung">
<menu label="Verpackung anlegen" data="new_package" />
<menu label="Verpackung bearbeiten" data="edit_package"
/>
</menu>
<menu label="Materialgruppe">
<menu label="Materialgruppe anlegen"
data="new_materialgroup" />
<menu label="Materialgruppe bearbeiten"
data="edit_materialgroup" />
</menu>
</menu>
</Menuebar>
It is a well-formed XML.
2. Delete a component out of storage
We have some own components (basically forms), which will be
created and shown by an construct e.g.
var myComponent : T_Component = new T_Component ;
this.addChild(myComponent)
Some of our forms will be created in an popup. On every call
of the popup, we lost 5 mb or more, all childs on the windows will
be removed by formname.removeAllChild();
What cann we do, that the garbage collector will dispose this
objects.
Is there a way to show all objects with references (NOT
NULL)?
I have read in the Flex Help, that
this.removeChild(myComponent) not delete the form and/or object out
of the storage.
Rather the object must be destroyed.
It is sufficient to call delete(myComponent) about remove
this object out of the storage as the case may be that the
garbage-collector remove this object at any time?
Or how can I destroy a component correctly. What happens with
the widgets on this component e.g. input fields or datagrids?
Are they also being deleted?
Thanks for your help.

If you mena the "photo Library" then you cannot delete it.
This is how iphone handles photos. There are not two copies. There a re simply two places from which to access the same photos. ALL photos synced to iphone can be accessed via Photo Library. Those same pics can be accessed via their individual folder.

Problem with setCursor for JButton in cell on JTable

i have a problem with setCursor to JButton that is in a cell of the JTable}
this is the code
public class JButtonCellRenderer extends JButton implements TableCellRenderer {
public JButtonCellRenderer() {
setOpaque(true);
public Component getTableCellRendererComponent(JTable table, Object value,
boolean isSelected, boolean hasFocus,
int row, int column) {
if (isSelected) {
setForeground(table.getSelectionForeground());
setBackground(table.getSelectionBackground());
else {
setForeground(table.getForeground());
setBackground(Color.WHITE);
setBorder(null);
if(table.getValueAt(row,column) == null){
setText("");
if(isSelected){
setBackground(table.getSelectionBackground());
}else{
setBackground(Color.WHITE);
}else{
if(table.getValueAt(row,column) instanceof JButton){
JButton _button = (JButton)table.getValueAt(row,column);
if(_button.getText().trim().equals("")){
setText("<html>"+ "Ver..."+"");
}else{
setText("<html>"+ "" + _button.getText() + ""+"");
return this;
}

Not quite sure I understand the problem, but I guess you have tried to call setCursor on your renderer and found it didn't work? The reason, I think, is that the renderer only renders a JButton. The thing that ends up in the table is in fact only a "picture" of a JButton, and among other things it won't receive and interact with any events, such as MouseEvents (so it wouldn't know that the cursor should change).
There are at least two alternatives for you: You can perhaps use a CellEditor instead of a CellRenderer. Or you can add a MouseListener to the table and then use the methods column/rowAtPoint to figure out if the cursor is over your JButton cell and change the cursor yourself if it is.

Problem with printing HTML container

Hi all,
I am having a problem with FlexPrintJob (or PrintJob) for the
mx.controls.HTML container. On print i receive only one page (only
the visible area) of my HTML container. How can i print multiple
pages from mx.controls.HTML?
Please Help!!!

And here we have the problems with Adobe's take on printing.
It would be much easier for every developer, if they could say
"HTMLContainer.print()" and have it print all of the text contained
in the html container, maybe even with integrated use of CSS print
stylesheets...
But, for the time being, the easiest method is to break all
of the text out into a second invisible (alpha = 0 NOT
visible=false) html container that is sized to the dimensions of
your page. Then you call addPage, scroll the container exactly 1
page, and call addPage again, repeating until you reach the end of
your content. This method of printing is necessary for people
developing an image builder, that want to make multi-sheet prints.
But people who are writing RIA's have the need to make multi-sheet
prints of TEXT that is not in a datagrid on a regular basis. This
is a SERIOUS limitation, and should have been taken care of prior
to the release of AIR 1.0

Datagrid scrolling problem

I'm trying to create a contact search/selection component
that works somewhat like a combobox (more like SuperComboBox
http://blog.strikefish.com/blog/index.cfm/2008/3/21/Flex-Smart-Combo-aka-look-ahead-combo
See sample at
http://www.eval.rmc.psu.edu/dgt/DataGridTest.html
Source view is enabled.
Basically, after the user types a few characters of the last
name, a datagrid (separate component) is popped up and presents a
list of matching contacts. The component includes view edit add
buttons, too (which are not active in the included example).
This all works great except for a couple of problems with the
popped up datagrid. I've tried both the standard and advanced dg's
and the both act the same.
If the number of rows returned exceeds the area of the
datagrid (12 rows in the example), the datagrid, as expected,
displays a vertical scroll bar. The scrollbar/datagrid doesn't work
properly at that point, though. Clicking the down arrow or in the
scrollbar track or the down arrow DOES NOT scroll the data.
Grabbing the slider bar and dragging it down DOES scroll the data
down. However, when I do scroll down using the slider, clicking on
a row does not fire the itemClick event, and the grid scrolls up to
the first 12 lines and highlights a row in the first 12 rows. CLICK
does get fired but always returns a row between 1 and 12.
Now, ideally, the user is going to type 3 or 4 characters of
the last name and zero right in on the contact they're looking for
without the need for scrolling, but there are always the outliers
like 'Smith' that return a large number hits (the example uses PA
Legislators offices, so it's not quite representative of the
end-use data set). Regardless, the datagrid object doesn't appear
to work correctly when it's a component -- I'm not sure if it's a
bona fide bug, or the whether it's that the grid is a component,
contained in a canvas, or being popped up that's the problem. More
likely, my flex newbie self just doesn't have some vital attribute
set correctly, or I'm doing something else that's not correct.
Any insights would be greatly appreciated.
Thanks,

DataGrid Refreshing Problem

Hi All,
First let me explain my problem clearly.I am facing the
problem with refreshing datagrid for add,update,delete operations.
For adding task(todo app) i am using another mxml
component(PopUpwindow).when i do add,delete or update, changes are
happening
in database pakka and fine.There is no error in that.Only
problem is when i add or delete or update a task, datagrid has to
get refresh with the updated or new data.Then only from ui
user will know that he added a task or deleted a task etc right.
sometimes it's refreshing fine and sometimes not.If it
doesn't refresh at all times i can think of my logic.But if it's
happening sometimes and sometimes not.
after add or delete or update am using below 5 lines of code
to refresh datagrid.
getList.send(); //sending request again to load new data
using httpservice.
datagrid.dataProvider = resultList; //resultList is
bindabale ArrayCollection variable.
resultList.refresh(); //this line not all giving any
changes.i think it's not working
datagrid.validateDisplayList();
datagrid.validateNow();
Thnaks & Regards,

Hey harsha,
the following code i'm using for deleting a task.
<mx:HTTPService id="getTodo" url="
http://dev.edinc.in:8080/poc/ToDo/GetToDo.jsp"
result="resultHandler(event)"/>
private function delTask():void
delTodo.cancel();
delTodo.send(delData);
getTodo.send();
deltaskname.text = "";
deltaskdate.selectedDate = new Date();
deltaskcategory.selectedIndex = -1;
deltaskpriority.selectedIndex = -1;
deltaskstatus.selectedIndex = -1;
Anything i need to apply here.
Thanks & Regards,
Premdas.
