Custom Renderer / Embedded Objects
In looking over the developer's guide, it suggests that one would have to create a custom XML renderer to handle deep structured documents (i.e., embedded objects). Is my reading of the renderer chapter correct?
Thanks in advance.

Custom Mapping: Storing embedded objects to column of Oracle Object type
Hello,
How hard in your opinion it would be to write custome mapping to store an
embedded object which only have simple fields in it (no references to other
persistent classes) to oracle object column. What superclass is the best for
the job?
Simplest approach I see is to define "none" mapped class for my embedded
object and use transformation mapping to do the job
What if I need to reference other persistent objects in my embedded one - do
you think it will make any difference?
Thank you for your assistance

Looks like transform mapping would not work - Kodo does not support object
mappings (use stream instead) or I am missing something?

Problem with JTree custom renderer when editing
I have a JTree which uses a custom renderer to display my own icons for different types of nodes. The problem I am having is when I setEditable to true and then attept to edit a node the icon switches back to the default icon, as soon as I am done editing it goes back.
What I am doing wrong?Here is my rendererer
public class DeviceTreeRenderer extends DefaultTreeCellRenderer implements GuiConstants {
public Component getTreeCellRendererComponent(JTree tree, Object value, boolean selected, boolean expanded, boolean leaf, int row, boolean hasFocus) {
JLabel returnValue = (JLabel)super.getTreeCellRendererComponent(tree, value, selected, expanded, leaf, row, hasFocus);
if (value != null) {
returnValue.setToolTipText(value.toString());
if (value instanceof Device) {
returnValue.setIcon(TREE_DEVICE);
if (!((Device)value).isAlive()) {
returnValue.setEnabled(false);
else if (value instanceof GuiPanelGroup) {
if (expanded) {
returnValue.setIcon(TREE_PANEL_GROUP_OPEN);
else {
returnValue.setIcon(TREE_PANEL_GROUP_CLOSED);
else if (value instanceof GuiPanel && ((GuiPanel)value).isDirty()) {
returnValue.setIcon(TREE_PANEL_DIRTY);
return returnValue;
}Here is my editor:
public class WwpJTreeCellEditor extends DefaultTreeCellEditor implements GuiConstants {
private WwpJTree tree;
* Creates a new WwpJTreeCellEditor.
* @param tree The WwpJTree to associate with this editor.
public WwpJTreeCellEditor(WwpJTree tree) {
super(tree, (DefaultTreeCellRenderer)tree.getCellRenderer());
this.tree = tree;
* Overrides the default isCellEditable so that we check the isEditable() method
* of the WwpJTreeNodes.
* @param e An EventObject.
public boolean isCellEditable(EventObject e) {
boolean returnValue = super.isCellEditable(e);
if (returnValue) {
WwpJTreeNode node = this.tree.getSelectedNode();
if (node == null || !node.isEditable() || node.isDragging()) {
returnValue = false;
return returnValue;
}In my JTree I make these calls:
super.setCellRenderer(new DeviceTreeRenderer());
super.setCellEditor(new WwpJTreeCellEditor(this));
super.setEditable(true); -
Help! Using a custom renderer to display an image
I have a JTable where I want to set the renderer of one column to a custom renderer. And I want this renderer to show either a play button image, or a stop button image, depending on the status, which is a Boolean value. However, the image won't show up when I run the application. Here's the code from the renderer...
public class StatusRenderer extends DefaultTableCellRenderer {
private ImageIcon playIcon = new ImageIcon("C:/play.jpg");
private ImageIcon stopIcon = new ImageIcon("C:/stop.jpg");
public StatusRenderer() {
setHorizontalAlignment(JLabel.CENTER);
public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected, boolean hasFocus, int row, int col) {
Boolean b = (Boolean) value;
setIcon(b.booleanValue() ? playIcon : stopIcon);
return this;
The application runs, but no icon shows up in the table cell. I'd really appreciate any help on this. Thanks.look at http://www2.gol.com/users/tame/swing/examples/JTableExamples1.html
for some great table examples (they may need minor mods to work on 1.3/1.4)
Basically I think you need something more like:
public class StatusRenderer extends JLabel
implements DefaultTableCellRenderer
public StatusRenderer() {
super();
setHorizontalAlignment(JLabel.CENTER);
public Component getTableCellRendererComponent(JTable table,
Object value, boolean sSelected,
boolean hasFocus, int row,
int col)
Boolean b = (Boolean) value;
setIcon(b.booleanValue() ? playIcon : stopIcon);
return this;
}Don't forget to add the renderer to the column you want it in ! -
'...' not appearing in obscured table cell when using custom renderer.
Hello all -
I am using a custom JPanel as a cell renderer in a JTable to display two icons per cell. Unfortunately, I am running into a problem that occurs when resizing a column such that the width of the column is less than the size of the cell content. Normally, when resizing a cell in this manner, it will start to cut off the text within the cell and add '...' to signify that some material is obscured. However, using my cell renderer, the text simply cuts off with no indication whatsoever there is more content that is being hidden. I have tried looking through the JComponent code to find a function to overload but I haven't had much luck. Does anyone have any suggestions?
For a simple example, compile and run the following code and try resizing the two columns. You should be able to notice the difference.
Thanks,
- Alex

Trex error: No embedded object found in document (Errorcode 14037)
Hi,
we have following problem with our crawler:
in the crawler 50 % of documents are returning the error "No embedded object found in document (Errorcode 14037)" and are not displayed in the trex monitor. All other documents are indexed correctly an are in the trex monitor in "OK".
We are on Stack 14 Patch 4.
Regards,
GerhardHi Gerhard,
Typically, errors codes 14XXX are related to filter problems during the preprocessing of documents. Details about TREX error codes are explained in the help portal and in the note 898404.
Unfortunatelly, filter problems could not be easily fixed. However, a good starting point would be to use a newer TREX release. If this doesnt help please open a Customer Message and attach documents, which causes the mentioned error. Please attach only not sensible documents!
Kind regards,

Cell with boolean value not rendering properly in Swing (custom renderer)

Component comp = super.getTableCellRendererComponent(table, value, isSelected, hasFocus, row, column);
int desCol = table.convertColumnIndexToView(1);
if (! isSelected && value instanceof Boolean && column == desCol) {
if (((Boolean) value).booleanValue()) {
comp.setForeground(hasIt);
} else {
comp.setForeground(UIManager.getColor("table.foreground"));
return comp;
* Override for performance reasons
@Override
public void firePropertyChange(String propertyName, boolean oldValue, boolean newValue) {
// EMPTY
@Override
protected void firePropertyChange(String propertyName, Object oldValue, Object newValue) {
// EMPTY
@Override
public void revalidate() {
// EMPTY
@Override
public void validate() {
// EMPTY
} // end classBut the rendering comes all wrong (a String saying true or false, not the expected checkbox from the default renderer) and also there is a weird flickring effect as this particular boolean column is editable (per table model, not show here)...
I can post the table model and the other renderer if needed (didn't want to put too much code on the question, at least initiallty).
Should I render a checkbox myself for this cell in the custom renderer? I'm puzzled as I expected the default renderer part of the code to do this for me instead.
Thanks!

Thats because the default render is a JLabel and it just displays the text from the toString() method of the Object in the table model.What I meant to say is that I expected the JCheckbox not a String representation of the boolean value.
Thats because a different renderer is used depending on the Class of data in the column. Look at the source code for the JTable class to see what the "default >renderer for the Boolean class" is. Then you can extend that or if its a private class then you will need to copy all the code and customize it.At the end I looked at the code and replicated the functionality I needed. I thought than maybe there was a way to avoid replicating the same logic all over again in order to implement this functionality. Good advice, though.
see you learned nothing from your last posting. This is NOT a SSCCE. 90% of the code you posted is completely irrelevant for the described problem. There is abosutelly no need to post the custom TableModel, because there is no need to use a custom TableModel for this problem. The TableModel has nothing to do with how a column is rendererd.The custom table model returns the type of the column (giving a hint to the renderer on what to expect, right?) and for the one that had a problem it says than the class is Boolean. That's why I mentioned it:
public Class getColumnClass(int columnIndex) {
// Code omited....
You also posted data for 4 columns worth of data. Again, irrelevant. Your question is about a single column containing Boolean data, so forget about the other columns.
When creating a SSCCE you don't start with your existing code and "remove" code. You start with a brand new class and only add in what is important. That way hopefully if you made a mistake the first time you don't repeat it the second time.That's what I did, is not the real application. I copy & pasted code in a haste from this dummy program on this forum, not the best approach as it gave the wrong impression.
Learn how to write a proper SSCCE if you want help in the future. Point taken, but there is NO need for you to be rude. Your help is appreciated.

Jose. -
Custom renderer (almost works)

Custom renderer in datagrid, needs to know if data changed
Hi,
I am hoping someone can help me out please.
I have a datagrid that uses a custom renderer that is
subclassed from a TextInput. When the user changes the data in a
cell, I need to color the cell. This is so that on a potentially
big grid, the user can easily see which cells he has made changes
to.
It is easy enough to set the color of the itemrenderer by
using setStyle() inside the overridden set data() method of the
custom renderer, but that is only a fraction of the solution. Since
Flex instantiates and destroys custom renderers at will depending
on if it is scrolled into view by the datagrid, keeping the state
of whether a value has changed inside the custom rendererer is not
an option.
So the only choice I have is to call back from the custom
renderer into the container that hosts the datagrid. As the
itemEditEnd event is handled in that container, a list of cells
that have had their data changed can be stored. The custom renderer
then needs to call back into the container with its cell
coordinates and ask if the data has changed, and if it has, set its
color.
How can a custom renderer know its cell position as x,y
coordinates? I see that TextInput implements IListItemRenderer
interface and has properties x and y, but putting a trace on these
gives me nonsensical numbers that seem to have no relation to the
cell coordinates.
The other thing I need to do is have the custom renderer call
back into the container that hosts the datagrid to know whether
data has changed. Is outerDocument the reference? Or is there a
proper way of doing this?
Thanks for the help you can give.Here is a simplified version of how we track the cell by cell
changes in a datagrid. It does require you to identify the fields
that will be editable and maintaining the original data for each
column in the data source.
Our production version is much more complex than this but it
will give you the idea.

Copy & paste embeded object to file system
Cross-post at:
http://stackoverflow.com/questions/27685791/copy-paste-embeded-object-to-file-system
Background:
I wrote a large piece of VBA code in an Excel workbook to help handle a lot of repeating jobs. I found it is painful to maintain and modify the code by using the "pool" VBA Editor. Then, I decided to move those VBA code to C# solutions, which I
suppose I can benefit from the modern editor - Visual Studio.
Problem:
Although I don't know too much about VBA, I know even less about C#. Hence I got some problem when I try to "translate" my VBA code to C#, and here is one of them:
I create a document-level solution for Excel. I need to embed some files (.cab, .exe) into the solution, so when I run a method (e.g. by clicking a button), those files will be copied to the file system, and do some job.
In VBA, I embedded those files in the Excel workbook, then I can copy the embedded objects to the clipboard by using the following VBA code:
Sheet1.OLEObjects("obj_cab").COpy
And then I can paste the object to the file system by using the following VBA code:
CreateObject("Shell.Application").Namespace("C:\Sample\").Self.InvokeVerb "Paste"
In the C# solution, I can use the following equivalent method to copy the embedded object to the clipboard:
Microsoft.Office.Interop.Excel.OLEObject OLEobj = (Microsoft.Office.Interop.Excel.OLEObject)sheet1.OLEObjects("obj_cab");
OLEobj.Copy();
Then I stuck here, I don't know how to get this object from clipboard and put it to the file system. The 'CreateObject' method does not exist in C#.
Anyone can help? Either a better way to embed those files or a working way to paste those objects (files) from clipboard to the file system?
Thanks a lot!Hi FantaC,
It's possible to save the oleobject to the disk. But it's not very simple. Because when you call the Copy method of OLEObject to clipboard, it's actually not the exact the oleobject file itself, it's actually a wrapper of the file, it means that it has different
file headers and some other information from the original oleobject file.
To save oleobject on the disk, you need to analyze the byte array by yourself, this would be a little complicated. You could check the answer in this thread for the code sample:
https://social.msdn.microsoft.com/Forums/vstudio/en-US/1ab7a178-8021-4c67-a14b-5031a254fd9c/saving-oleobject-content-to-a-file

JTable loses selection with custom renderes
Hello,
I have a JXTreeTable with five columns, out of which I have custom rendered 3 columns. When I select a node is the tree, the corresponding columns are selected except the custom rendered columns. Any reason why it would be so?.
I have set the row selection enabled to be true.
I know I shouldnt be posting JXTreeTable questions here, but am hoping any JTable guru's might be able to help me out
Thanks
KThe general structure of the renderer code would be:
class CustomRenderer extends DefaultTableCellRenderer
public Component getTableCellRendererComponent(
JTable table, Object value, boolean isSelected, boolean hasFocus, int row, int column)
super.getTableCellRendererComponent(table, value, isSelected, hasFocus, row, column);
if (! isSelected)
// add your custom code here to change background
return this;

DropDownList as a custom renderer
Any idea how to create a custom renderer based on DropDownList for dataGrid?
ThanksI'm sorry but that went a little over my head, could you point me in the direction of an example, alternativly I have extracted the following example from my application showing what I have so far. If I skin my ItemRenderer for the DropDownList, I'm worried it will upset the ItemRenderer for each of the items in the list!

We are attempting to add OfficeWriter report rendering extensions for SSRS 2012 in SharePoint (2010) integrated mode through powershell. The documentation for “New-SPRSExtension” is rather
sparse and we have not found any clear examples on the internet. With SSRS 2012 in native mode, we make the following two changes to the config files:
We add the following report rendering extension declaration to
RSReportServer.config:
<Configuration>
<Extensions>
<Render>
<Extension Name="XLTemplate" Type="SoftArtisans.OfficeWriter.ReportingServices.ExcelTemplateRenderer,
SoftArtisans.OfficeWriter.RS2008"/>
<Extension Name="WordTemplate" Type="SoftArtisans.OfficeWriter.ReportingServices.WordTemplateRenderer,
SoftArtisans.OfficeWriter.RS2008"/>
</Render>
</Extensions>
</Configuration>
We add the following security trust codegroup to
RSSvrPolicy.config:
<configuration>
<mscorlib>
<security>
<policy>
<PolicyLevel version="1">
<CodeGroup version="1" PermissionSetName="Nothing">
<CodeGroup
version="*"
PermissionSetName="FullTrust"
Name="SoftArtisans_OfficeWriter_Strong_Name"
Description="This
code group grants SoftArtisans OfficeWriter code full trust.">
<IMembershipCondition
class="StrongNameMembershipCondition"
version="*"
PublicKeyBlob="00240000048000009400000006020000002400005253413100040000010001004779CB207F11

B4D23D9C6AF83431D88A7EF42BB01082913F3560DCB50129C5BBA7ECA0DE8BC286DA74F58FADE"/>
</CodeGroup>
</CodeGroup>
</PolicyLevel>
</policy>
</security>
</mscorlib>
</configuration>
What would be the equivalent syntax for “New-SPRSExtension” to do the above for SSRS 2012 in SharePoint (2010) integrated mode?
Alison Bird SoftArtisans Technical Services www.softartisans.comHi Alison,
Unlike the deployment of other custom extensions such as custom delivery extension and data processing extension, it is not necessary to add a code group for the custom assembly that grants FullTrust permission for the extension during the deployment of
custom rendering extension. If you have copy the custom assembly to the %ProgramFiles%\Microsoft SQL Server\MSRS11.<InstanceName>\Reporting Services\ReportServer\Bin folder, and modify the RSreportserver.config file to add the extention entry properly,
please open the SSRS Service Application created on the SharePoint and verify that your extension is included in the list of available export types for a report.

Best Practice : Creating Custom Renderer for Standard Component
I've been reading the docs and a few threads about Custom Renderers. The best practice seems to be to create a Custom Component where you need a Custom Renderer. Is this the case?
See [this post|http://forums.sun.com/thread.jspa?forumID=427&threadID=520422]
I've created several Custom Renderers to override the HTML provided by the Standard Components, however I can't see the benefit in also creating a Custom Component when the behaviour of the standard component is just fine.
Thanks,
Damian.It all depends on what you are trying to accomplish. Generally speaking if all you need is for the user interface output to be changed then a renderer will work just fine. A new component is usually made in order to provide some fundamental change in server side functionality not related to the user interface. - Ponderator
