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 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

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...

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

Bugs: open new doc, custom XMP panel crash

When opening a new document after starting Photoshop, it appears with half a checkboard pattern:
Drawing on it looks like below:
I also had an issue where I closed the doc (without saving) after drawing, then opened a new doc. The previous drawing then appeared partially twice (large, and a small version in top left corner) in the new doc, this only happened once though.
I added a custom XMP panel that works fine with CS5 to $user-dir\AppData\Roaming\Adobe\XMP\Custom File Info Panels\4.0\panels
On selecting the custom panel, in the File Info window, the panel window / CS6 crashes. (The grey window in the sshot below is an imprint of the irfanview settings I used to take these screenshots, this imprinting behaviour (not sure if it has a proper name) is reasonably common with crashed programs).

According to Nvidia's website, I already have the latest drivers installed (I updated them just a few days ago). I turned off hardware acceleration as you suggested, and that fixed the problem.
You can download the XMP panel that causes the crash from: http://www.iliveinabin.com/image-xmpPanel%20v2.zip That contains the source for the panel and also the compiled panel I'm using, which is in the target folder.

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.

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.

Using a repeater in a custom FileInfo Panel --data binding error

When I developed a custom FileInfo panel in Flex Builder 3, I could use an array to populate a checkBox control inside a repeater, and it worked.
Now, using Flash Builder 4, data binding with <mx:Repeater> doesn't seem to work, resulting in an empty fileInfo panel.
When I remove the dataProvider from the <mx:Repeater> tag, my panel displays, but without the repeater. How can I specify the dataProvider in a different way that works?
Thanks
The code:
<fi:XMPForm
          xmlns:mx="http://www.adobe.com/2006/mxml"
          xmlns:fi="com.adobe.xmp.components.*" width="100%" height="100%"
          label="TestPanel2_1" xmlns:s="library://ns.adobe.com/flex/spark" >
     
     <fi:XMPNamespaces>
          <fi:XMPNamespace prefix="dc" value="http://purl.org/dc/elements/1.1/"/>
     </fi:XMPNamespaces>
     <mx:Script>
          <![CDATA[
               import mx.collections.ArrayCollection;
               [Bindable] public var newArray:Array =["One", "Two", "Three", "Four", "Five"];
          ]]>
     </mx:Script>
     <fi:XMPFormItem>
          <mx:VBox id="primaryFrame" width="800">
               <mx:Repeater id="myRep" dataProvider="{newArray}">
                    <mx:Label text="{myRep.currentItem}"/>
               </mx:Repeater>
          </mx:VBox>
     </fi:XMPFormItem
</fir:XMPForm>

Okay, I may have been making a rookie mistake. I see online reports that you can't bind an array to a repeater (even though it has worked for me).
I've added the following variable to make my array an array collection:
[Bindable] public var newArray2:ArrayCollection = new ArrayCollection(newArray);
After changing the binding of the repeater to the new array and running the build, the fileInfo panel still does not function.
Any thoughts?

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)

h:form in customized rendering of jsps

But i am facing another problem.
i am rendering two jsp pages
index.jsp<-1.jsp
<- 2.jsp
(rendering the two pages based on selection in tabbedpane custom component)
I have a <h:form> tag with unique ID in index.jsp .
I have my custom tabbedpane component in it.
Now using this component i am calling other two pages and renderering them in the same component's workspace.
When i use another <h:form> tag in either of the 1.jsp or 2.jsp the tabs work for only one time.

As in a Standard Shell i have header,footer, navigation area ,workspace area.
I am making a custom tabbedPane component that controls both navigation and workspace area simultaneously.
Also the url that i return ,is being rendered by method
getRequestDispatcher(display).include(request, response);

now this pages which i am rendering ,if they contain <h:form> tag even with distinct ID --the component works for only one time .

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

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
      A14C63F96E57DFB71B1535280C37DA2CB5BA37D78A9882414DB11F67FD66DEBC4AD93DD34F4A587D34D
      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?

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
