JTree custom renderer - JScrollPane

Hi,
I am building a JTree and need a custom renderer that will allow me to display the contents of certain leaf nodes in a JEditorPane that is contained in a scrollpane as the leaf may contain a varying amount of text.
I have managed to get a renderer displaying the text as expected however the scrollbars do not work as I hoped - I cannot scroll down the editorpane.
Has anyone got an example of a renderer that uses a scrollpane, any help/suggestions would be gratefully received.
Thanks

Return the size of your editor pane in customized cell renderer's getPreferredSize() method and set JTree rowHeight to zero. When row height is 0, it use renderer's getPreferredSize() to get size of the cell, I think. I have made custom cellrenderer which extends Jpanel and in getCellRendererComponent I add there another panel which contains buttons etc. I have used super.getPreferredSize() in my renderer's getPreferredSize() method.

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);

JTree custom renderer setting selection background color problem

Hi,
I have a JTree with a custom icon renderer that displays an icon. The JTree is part of a TreeTable component. Iam having a problem setting the selection background uniformly for the entire row. There is no problem when there is no row selected in the JTable.
My present code looks like this:
Iam overriding paint in my renderer which extends DefaultCellRenderer.
     super.paint(g);
        Color bColor = null;
        if(!m_selected) {
             if(currRow % 2 == 0) {
                  bColor = Color.WHITE;
             } else {
                                                bColor = backColor;
        } else {
             bColor = table.getSelectionBackground();                  bColor = getRowSelectionColor();
     if(bColor != null) {
                       g.setColor(bColor);
         if(!m_selected) {
               g.setXORMode(new Color(0xFF, 0xFF, 0xFF));
         } else {
             g.setXORMode(new Color(0x00, 0x00, 0x00));
              I have a color I arrive at using some algorithm that I want using method getRowSelectionColor(). The other cells in the row have this color. But the cell containing the tree node shows different color. Iam not able to arrive at the right combination of the color to set and the xor color so my tree node also looks like the other cells in the row.
It is not a problem really as the table still looks good. Its just that the tree node looks like it has been highlighted and this might cause a problem when a table cell is highlighed later on in the application ( two cells in the row would be highlighted causing confusion).
Any help would be appreciated.

Hi Camickr,
Thanks for the reply. Iam sorry I didn't include the sources the first time around. There were too many of them. I have created a small, self-contained, compilable program that demonstrates the problem and including it herewith. Still there's quite many files but they are all needed Iam afraid. The only one you will have to concern yourself fior this problem is the file IconRenderer.java. The treenode background and the other cells background are not in sync when table row is not selected in this example though. But they are in my real program. I just need them to be in sync i.e have the same background color when the row is selected.
Your help would be very much appreciated.
These are the files that are included below:
1. AbstractTreeTableModel.java
2. Bookmarks.java
3. BookmarksModel.java
4. DynamicTreeTableModel.java
5. IconRenderer.java
6. IndicatorRenderer.java
7. JTreeTable.java
8. TreeTableExample3.java (contains main)
9. TreeTableModel.java
10. TreeTableModelAdapter.java

Making JTree custom renderer panel scalable

Hi, everyone. I have made custom TreeCellRenderer which extends JPanel. Panel's background is in different color than JTree's backgound. I need to get my panel rendering the nodes to fill the whole space JTree has in it's parent panel horizontally. For now I have put static width to nodes and it looks fine, but it's not scalable. If I don't put any sizes the panel takes only the size it needs in cell and the outfit is crappy because of panel's different bgcolor. Is there any easy way to make rendering panel use the width which JTree has in it's container. I have implemented getPreferredSize() method in custom TreeCellRenderer and now it returns the static width and height of the rendering panel. Do I have to get JTrees container panel's width every time and pass it to renderer and get size somehow from there or is there some easier way.
-e

Yes, there is a reason. Different levels of nodes contain different components. Example main level nodes have print and save buttons on the most right of the panel. Only leafs have same bgcolor as the tree has and those are already now scalable, because size is not set for them.

JTree selection problem when using custom renderer and editor

Hello:
I created a JTree with custom renderer and editor.
The customization makes JCheckBox to be the component
responsible for editing and rendering.
The problem is that when I click on the node with the checkbox
the JTree selection model does not get updated.
Without customizations of the editor and renderer the MouseEvent would be fired and BasicTreeUI$MouseHandler.mousePressed() method would call
the selectPathForEvent() method which would be responsible for updating
the selection model. At the same time if I attach a mouse listener to the JTree (customized) I see the events when clicking on the nodes. It seems like the MouseEvent gets lost and somehow as a result of which the selection model does not get updated.
Am I missing something?
Thanks
Alexander

You probably forgot to call super.getTreeCellRendererComponent(...) at the beginning of your getTreeCellRendererComponent(...) method in your custom renderer.
Or maybe in the getTreeCellEditorComponent(...) of the TreeCellEditor...

Disabling JTree in a JScrollPane.

Greetings,
I'm trying to figure out how to disable a Jtree that is inside a JScrollPane. I've tried using setEnable(false) but it doesn't even phase it, its still enabled (I can expand branches and its not greyed out) . I've tried setting the JScrollPane to setEnable(false) but once again nothing really changed. The only thing I can think of is that using setEnable(false) is not propigating to the cell renderers for the JTree for some reason. Is there a way to disable the JTree without writing a custom renderer?

Also make sure that the JScrollBars are set to not focus.

'...' 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

Jtree cutom renderer and buttons

I am trying something new in a jtree and have no idea where to start
I have written a custom renderer that is a panel
In this panel I have an Icon and some text (both labels) and 2 buttons (up and down)
The renderer looks pretty but does nothing
Is there any way I can make it so that when the up button is pressed the tree will move this node up and when the down button is pressed it moves the node down.
Hope someone can help

JTable JTrees and components that use renderers do not paste the renderer component at the desired location but only paint their picture . That means the place where u r expecting ur JPanel is occupied by its image .
Now what u need to do will be
1. Handle the mouse click on the component which has ur renders .
2. use the mouse clicks to find out the component on which the mouse was clicked
3. take appropriate action
may be i'll post u an example in short while ..
try ur luck

          setOpaque(true);
     @Override
     public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected, boolean hasFocus, int row, int column) {
          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

     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.

JTree Custom TreeCellRenderer problem on Mac OS + Firefox

Hi,
I have a JApplet containing a JTree component with custom renderer that implements TreeCellRenderer to display CheckBox along the tree nodes.
Everything works fine on Window and Linux OS (firefox browser)
Problem is with :
Firefox + Mac: applet fails to load because getTreeCellRendererComponent() does not seem to get invoked.
Appreciate you time and thoughts on the problem.
Edited by: rg18mar on Nov 27, 2007 10:31 PM

Our only other environment we could set up was on Mac OS 10.7.5, and we could not reproduce the issue. Based on that it would appear to be something new with Mac OS 10.8.

Jtable custom renderer

how to set or create custom renderer for a Jtable ?.. i want have following components in each cell of jtable.
1)checkbox
2)icon
3)combobox
i know how to render these components for Jtree, but i didn't get any method like setCellRendere() for Jtable.
plz help !!

You can use the both:
JTable method:
+Sets a default cell renderer to be used if no renderer has been set in a TableColumn.+
public void setDefaultRenderer(Class<?> columnClass, TableCellRenderer renderer)TableColumn method:
+Sets the TableCellRenderer used by JTable to draw individual values for this column.+
public void setCellRenderer(TableCellRenderer cellRenderer)

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 !

Adding a custom rendering extension to SQL Server Reporting Services 2012 for SharePoint 2010 integrated mode

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
      5E86EF9DD3233F9F130F8891911345176650F72330F84CA3F54C96DEB08439680660F02872EEF5DA3955

      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.com

Hi 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

Custom rendering extensions not working in SSRS Report Designer (rsreportdesigner.config)

My custom rendering extension is working in Report Builder (in RSReportServer.config), but not in Report Designer (in RSReportDesigner.config): instead of adding a "TXT" export option, it's just adding a duplicate "CSV" option.
SUMMARY:
Is there a way to get these features working, with Report Designer?
DETAILS:
We are running SSRS (Reporting Services) under SQL Server 2008 R2.
Here's my rendering section:
    <Render>
      <Extension Name="XML" Type="Microsoft.ReportingServices.Rendering.DataRenderer.XmlDataReport,Microsoft.ReportingServices.DataRendering" />
      <Extension Name="CSV" Type="Microsoft.ReportingServices.Rendering.DataRenderer.CsvReport,Microsoft.ReportingServices.DataRendering" />
      
      <Extension Name="TXT" Type="Microsoft.ReportingServices.Rendering.DataRenderer.CsvReport,Microsoft.ReportingServices.DataRendering">
       <OverrideNames>
           <Name Language="en-US">TXT(ASCII,NoColHds)</Name>
       </OverrideNames>
       <Configuration>
          <DeviceInfo>
              <FileExtension>txt</FileExtension>
               <FieldDelimiter>,</FieldDelimiter>
               <Encoding>ASCII</Encoding>
               <NoHeader>true</NoHeader>
           </DeviceInfo>
       </Configuration>
      </Extension>
      <Extension Name="IMAGE" Type="Microsoft.ReportingServices.Rendering.ImageRenderer.ImageRenderer,Microsoft.ReportingServices.ImageRendering" />
      <Extension Name="PDF" Type="Microsoft.ReportingServices.Rendering.ImageRenderer.PDFRenderer,Microsoft.ReportingServices.ImageRendering" />
      <Extension Name="HTML4.0" Type="Microsoft.ReportingServices.Rendering.HtmlRenderer.Html40RenderingExtension,Microsoft.ReportingServices.HtmlRendering" Visible="false" />
      <Extension Name="MHTML" Type="Microsoft.ReportingServices.Rendering.HtmlRenderer.MHtmlRenderingExtension,Microsoft.ReportingServices.HtmlRendering" />
      <Extension Name="RPL" Type="Microsoft.ReportingServices.Rendering.RPLRendering.RPLRenderer,Microsoft.ReportingServices.RPLRendering" Visible="false" />
      <Extension Name="EXCEL" Type="Microsoft.ReportingServices.Rendering.ExcelRenderer.ExcelRenderer,Microsoft.ReportingServices.ExcelRendering" />
      <Extension Name="WORD" Type="Microsoft.ReportingServices.Rendering.WordRenderer.WordDocumentRenderer,Microsoft.ReportingServices.WordRendering" />
    </Render>
When I add the above "TXT" section to RSReportServer.config, then Report Builder (and production) both show an export option "TXT(ASCII,NoColHds)".
But when I add this "TXT" section to RSReportDesigner.config, and then (in Report Designer / BIDS) attempt to export from a "Preview" of the report, the export drop-down does not show a "CSV" option followed by a "TXT"
option, but instead shows the "CSV" option twice.
This simply limits testing of the export option, to Report Builder... or requires any reports be published from Report Designer before they can be tested with
this export option.
(FYI, why this export option: compliance in our industry requires sending data to government agencies, in text files, with fixed-length columns, and ASCII encoding. Also, we're attempting to give the production of these files to the *users* managing
communication with those agencies... so we're putting them into SSRS.
I worked around the fixed length columns (and no delimiters -- no commas), by writing a version of the report where all string columns are padded, and all columns are concatenated, to form ONE LONG COLUMN... but Reporting Services' CSV export format produces
a Unicode file (UTF-8, which the agency rejected, because it had a leading "ï»¿", or "EF BB BF" in hex), whereas the agency requires an ASCII file.)

Hi Doug_atMidway,
According to your description, you want to enable your custom render extension. Right?
In Reporting Services, if you want to deploy the custom extension, you just need to add the extension into rsreportserver.config file. The
RSReportDesigner.config file stores settings about the rendering extensions available to Report Designer. Since you still use the csv rendering extension in your assembly, we don't need to do any modification in rsreportdesigner.config file. Pleaes
refer to the links below:
Thanks for attempting to help, Simon.
As my question states, I've *already done* both the above: changed (1) rsreportserver.config and (2) rsreportdesigner.config. I added the same code, shown above, to both files. I did that so I could see the new "txt" extension
both (1) when exporting in production and Report Builder, and (2) when exporting in Report Designer's "preview".
The change in (2) is not working: I do not see the "TXT" extension in Report Designer, when I try to export from a preview. Instead, Report Designer shows the CSV extension repeated.
Thanks for the docs. I consulted them (well, I consulted the EQUIVALENT pages, for SQL Server 2008 R2), when creating my block of code above.
Do you see anything to correct, in my code?
Are the features I'm using actually working, with rsreportdesigner.config?
Thanks again,
-- Doug
