Problem in JTable Renderer and Editor

Hi All
I have created a JTable with one Column have the Custom TableCellRender, and TableCellEditor
Which has the a JPanel with one lable and a button.
Problem is:
I have to edit the content of table by clicking the button, i will select some data from another dialog,
if i select that data the cell contenet is not updating, and i can not able to select any other cell in the table.
if i resize the colomn the above problem will solve.
Please help on this to fix

Hello,
Very sorry but it is difficult to understand your problem.
Anyway you should have a careful look on Sun's Tutorial for JTable:
http://java.sun.com/docs/books/tutorial/uiswing/components/table.html
Be patient as JTable are complex components.
Good luck, Frank

JCheckBox as nodes in JTree having problems with custom renderer and editor

Ok, let me give some background. I have an XML document that I am parsing and reading in as a JTree. Works fine.
Next, I have overwritten the DefaultTreeCellEditor to return a JCheckBox and in this implementation of the getTreeCellEditorComponent(), I actually tell the node that he is selected. Works great.
Next, I have overwritten the DefaultTreeCellRenderer to return a JCheckBox and in the implementation of the getTreeCellEditorComponenet, I actually check to see if the Node is selected in the tree based upon the isSelected state of the actual Tree Node set in the tree cell editor, and if so, I set the JCheckBox to selected(true).Works Great.
Now, here is the issue. If a node in the tree is selected that contains children, then I want all of the children of that node to also be selected. However, when I select a node with children only the selected node is changed, and then a few moments later, the system repaints the entire tree and ALL nodes int the tree are set to a selected state. Strange? Yes. Any ideas?? WONDERFUL!! :)
Here is the TreeCellEditor code:
public Component getTreeCellEditorComponent(JTree tree,
Object value,
boolean isSelected,
boolean expanded,
boolean leaf,
int row)
elementCheckBox_ = new JCheckBox();
Component result = null;
System.out.println("isSelected? Editor = " + isSelected);
TreePath newPath = tree.getPathForRow(row);
System.out.println("value = " + value.getClass().toString());
if(value instanceof IMarketTreeNodeElement)
if(isSelected)
if(((IMarketTreeNodeElement)value).isSelected())
((IMarketTreeNodeElement)value).setSelected(false);
else
((IMarketTreeNodeElement)value).setSelected(true);
elementCheckBox_.setSelected(isSelected);
return elementCheckBox_;
Here is the TreeCellRenderer code:
public Component getTreeCellRendererComponent(JTree tree,
Object value,
boolean selected,
boolean expanded,
boolean leaf,
int row,
boolean hasFocus)
Color colSelBorderCol = UIManager.getColor
("Tree.selectionBorderColor");
selBorder_ = BorderFactory.createLineBorder(colSelBorderCol, 1);
normBorder_ = BorderFactory.createEmptyBorder(1,1,1,1);
elementCheckBox_.setText(value.toString());
if(selected)
elementCheckBox_.setSelected(selected);
elementCheckBox_.setForeground(Color.YELLOW);
elementCheckBox_.setBackground(Color.RED);
else
elementCheckBox_.setForeground(tree.getForeground());
elementCheckBox_.setBackground(tree.getBackground());
if (hasFocus)
elementCheckBox_.setBorder(selBorder_);
else
elementCheckBox_.setBorder(normBorder_);
return elementCheckBox_;
Here is the Node Code setting all child nodes to selected:
public void setSelected(boolean selected)
isSelected_ = selected;
if(isSelected_)
if((this.getTagName() == "MARKET") ||
(this.getTagName() == "TIER") &&
(this.getChildCount() != 0))
selectChildren(true);
else
if((this.getTagName() == "MARKET") ||
(this.getTagName() == "TIER") &&
(this.getChildCount() != 0))
selectChildren(false);
public boolean isSelected()
return isSelected_;
public void selectChildren(boolean selected)
int children = getChildCount();
for(int i = 0; i < children; i++)
IMarketTreeNodeElement elem = (IMarketTreeNodeElement)
this.getChildNodes().item(i);
isSelected_ = selected;
Thanks for any help! :-)

I tried to run your sample code and it won't compile. The header files:
#include
#include
#include
#include
#include
do not exist on my install of MeasurementStudio. I am a bit suspicous that I don't have the latest and greatest (loading the dialong resouce gave version warnings). Here is one of my header file headers:
//==============================================================================
// Title : NiAxes3d.h
// Copyright : National Instruments 1999. All Rights Reserved.
// Purpose : Defines the CNiAxes3D class.
//==============================================================================
I
looked on your updates site and don't really see an update that applies to ComponentWorks or MeasurementStudio. My version per the MAX program for 3DControls is 3.5.549.
Do I need a newer version? What do I have to do to get the updated version? What does it cost?

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...

Help on Renderer and Editor

Hi All,
I am new to Swing and get really confused with the concepts of Renderer and Editor. I don' t really understand what Renderer is, why/when use it and how to use it. Similarly questions for Editor. There are a lot of classes related to renderer, such as TableCellRenderer, DefaultCellRenderer etc and they make me crazy. What makes different when we use Renderer and Editor?
Thanks.

Read "Concepts: Editors and Renderers" for JTable at http://java.sun.com/docs/books/tutorial/uiswing/components/table.html#editrender and "Customizing a Tree's Display " for JTree "http://java.sun.com/docs/books/tutorial/uiswing/components/tree.html#display

JTable custom cell renderer and editor breaks row sorting

Hello Forum,
I have a JTable on which I set setAutoCreateRowSorter(true); I then hook up a custom cell editor and renderer for the Date class.
this.tblLeden.setDefaultRenderer(Date.class, new DateCellEditor());
this.tblLeden.setDefaultEditor(Date.class, new DateCellEditor());
The sorting for that particular row then breaks, it works fine for every other row. How do I fix this? Just directions where to look would be great too.
Here is my code for the renderer/editor:

Problems with JTable Renderer

I have a problem with applying a custom renderer. I know the renderer works so thats not the problem. If I do like this:
DefaultTableModel aDefaultTableModel = new DefaultTableModel(data, columnNames);
it works. But if I do like this:
DefaultTableModel aDefaultTableModel;
aDefaultTableModel.setDataVector(data, columNames);
is doesn't, why?

I think maybe it's not the renderer at all. It may be my custom TableModel thats causing problems. Now this doesn't work:
private JTable aTable;
private CustomTableModel aTableModel;
public MyProgram() {
aTableModel = new CustomTableModel();
aTable = new JTable(aTableModel);
aTableModel.setData(data, columnNames);
private class CustomTableModel {
private String[] columnNames = null;
private Object[][] data = null;
public CustomTableModel() {
columnNames = new String[0];
data = new Object[0][0];
... snip
public void setData(Object[][] data, String[] columnNames) {
this.data = data;
this.columnNames = columnNames;
fireTableDataChanged();
... snip
Now, why doesn't that setData method work??

This is going to be a bit hard to explain.. Jtable +rendererd and editors

I have a custom cell renderer that returns a panel, from a vector of panels, dependant upon the row. The panel from the vector is made up of different numbers of panels with some graphics drawn on them.
Ok so when I change the vectors of panels, the tables cells update fine and all the correct graphics are displayed.
BUT>.. when I load the vectors from a file and try and intialise the table it does not display the panels. It leaes space for the panles in the cell but it does not draw the graphics in them.
I hope you understand!! This is a prettty big deal to me any help would be excellent.
here comes the lengthy code snippets!!!!
RENDERER>>>>>>>>>>>>>>>>>.
class OverCellRendererClass extends DefaultTableCellRenderer {

return op;
HOW THE TABLE IS INTIALISED>>>>>>>>>>>>>>>>

               for (int i =0; i < size; i++)

                    m.addRow(info);
               m.fireTableRowsUpdated(0,size-1);
COLUMN FOUR HAS MY RENDERER SET AS ITS RENDERERthe create over panels function just takes in information from a source.
I know that the informatino is all there its just not drawing the graphics!!!!
Thanx

This is a wild guess, but are you loading images into the vector? Many image methods return immediately and the graphic is loaded in the background. It could be that your code continues and attempts to display images that have not yet loaded.

Table header renderer and editor

Hi,
I am making a customised table, in which the column headers are required to be JButton components.I want to catch action events on the headers.Can anyone suggest how should i go about it?
thanx,
regards.

This isn't as easy as it should be because of how the header is drawn. It doesn't create individual header components, it uses one component like a rubber stamp to draw the headers. So it isn't as simple as just sticking in some buttons in the proper place.
Here is a pretty good example that might get you started:

Problems in JTable

Hi all
I have added a JButton in a Jtable cell. Now i want to fire actionPerformed event. But i could not click on it ....
Any suggestion plz.
Regards
Umer

You don't add components to a table. You add data. The data is then rendered to look like a component.
To solve your problem you need a custom renderer and editor. Read the section from the Swing tutorial on: [url http://download.oracle.com/javase/tutorial/uiswing/components/table.html#editrender]Concepts: Renderes and Editors to understand the basics.
Then you can check out [url http://www.camick.com/java/blog.html?name=table-button-column]Table Button Column for an implementation of these concepts.

ProRes422 effects rendering and graphics card

We are having problems with effects rendering and playing using Prorez 422 HQ.
Our system is: Mac Pro 2x 2.66 GHz dual core Xeon, 4GB RAM, with a NVidea GeForce 7300GT graphics card with 256 MB VRAM, pulling media off of a Facillis Terrablock.
We get the following error message:
"The effect "Desaturate" cannot be rendered in sequence of this size with the current graphics card"
The time line shows the effect as rendered, but it will not play in the canvas desaturated. It does show in the Browser desaturated.
Settings are at Safe RT, High Quality, full frame rate - we need to go out to tape.
Obviously, the error indicates we should use a different graphics card, but is this correct? Everything else I read indicates that this card should be enough to edit and do effects with in FCP. Is there a problem with using this card for Prorez or HD material? Is there a settings issue we should be looking at? What is the recommended card? Are there any links to the recommendations or known issues? Any help is greatly appreciated.
Thank you,

I'm assuming that's an FXPlug filter. ATI cards handle FXPlug filters netter than nVidia cards, so if that's the problem, I wonder if one of these workarounds might help:
1) Place the clip, with enough heads and tails to allow for transitions in the final sequence, in a new sequence, apply the filer and see if it renders OK. Export that to a QT movie, import that back into the project and drop it into the final sequence in place of the unrenderable clip that's there now.
2) Put the clip into a new sequence, apply the filter but don't render. Export to a QT reference movie, and drop that into Compressor, and select the same codec as you are using for the final sequence and see it that will render.

I think Problem is between these code only

               TableCellRenderer renderer = null;
               TableCellEditor editor = null;

                                                            itemTable.getColumnModel().getColumn(k).setCellRenderer(renderer);or in this renderer
class TextAreaCellRenderer extends JTextArea implements TableCellRenderer
     public TextAreaCellRenderer() {
          setEditable(false);
          setLineWrap(true);
          setWrapStyleWord(true);
     public Component getTableCellRendererComponent(JTable table,
          Object value, boolean isSelected, boolean hasFocus,
          int nRow, int nCol)
          if (value instanceof String)
               setText((String)value);
          // Adjust row's height
          int width = table.getColumnModel().getColumn(nCol).getWidth();
          setSize(width, 1000);
          int rowHeight = getPreferredSize().height;
          if (table.getRowHeight(nRow) != rowHeight)

JTable custom cell editor focus problem

Hi I have created a JTable (using Java 1.4.2) and have three cell Editors, one is a JFormattedTextField, one is a JComboBox and one is a custom cell editor.
When I press tab I can select the cell with the JFormattedTextField and when I start typing the JFormattedTextField accepts my input and it is displayed in the cell. This is the type of behaviour I would like but it does not seem to work for my other 2 cell editors:
When I tab to the JComboBox cell I can see that the cell is selected but typing or using the arrow keys does not allow me to select a new value in the JComboBox. (I have also tried typing space or enter to activate the JComboBox whilst the cell is selected.) The only ways to select a new value at the moment is to first click on the cell with the mouse and then use the keyboard to select a new value. It is like the actual JComboBox is not receiving the focus? Does anyone know how to solve this problem?
I also seem to have the same problem with my custom cell editor. My custom editor is a JPanel which contains JFormattedTextField again I can tab to the cell and see that it is selected but to activate the JFormattedTextField I have to actually select it with the mouse.
I have been stuck on this for some time so if any one has any suggestions they would be much appreciated !

Jtable Renderer Problem

Hi
I have Jtable table where i am setting the model by using TableModelSorter model (extending defaulttablemodel), this table moedel is used for sorting.
tblDocs.setModel(new TableModelSorter(modelDocument,tblDocs.getTableHeader()));
The same Jtable have renderer where last column have Jcombobox componet.
Here propbllem is that Jtable sorting is working properly but once i click renderer column header
Jtable renderer is getting lost.
Please tell me where i am doing mistake.
Regards
Qaisar

Just a remark that nowadays, considering JTable has built-in support for row sorter, that enable you to specify sorting order, sorting algorithm (comparators), and to sort on demand, my first reaction is to warn that developping/using a specific model class for that is overkill (and probably inefficient, as the "sorting model" would likely fire spurious TableEvents although the gut contents have not changed (just been reordered).

Rendering and Artifacting problems on Mac OS

I am currently deveolping a game and after recently installing Flash Player 11 I have been getting rendering and artifacting issues along with mouse over states of the stage not being recongnized. The swf works fine in the flash preview of Flash CS5 and on a windows machine. The issue only shows up on Mac OS. The problem occurs in Chrome, Safari, and Firefox. This is also occuring on others Macs in the office as well. Link to the game http://bs-dezign.com/2011_Cyclones.swf. The viewing area is down the center of the stage aligning with hud.
Thank you for any help your can provide.

JTable - help with custom cell renderers and editors

I've got myself into a bit of a mess with cell renderers and editors.
I've got a custom component that wants displaying in a column and then hand over all functionality to this component when you start editing it.
Now how I went out about this was to create a custom cell renderer that extends this component and implements TableCellRenderer.
I then created a table cell editor that extends AbstractCellEditor and implements TableCellEditor and this cell editor creates a new component when it's initialized. I then use setCellEditor(new MyCellEditor()) on the column and setCellRenderer(new MyCellRenderer()).
This works slightly but I'm wondering how this is all implemented.
When I set the cell editor on it's own it seems to be sharing a reference to the single component that's being used which means that if you edit one cell all the cells get changed to the new value.
Thanks for the help,
Alex

only a few forums are actually browsedAnd theSwing forum is one of the most active. Did you search it for editiing examples? I've seen many editing examples posted in a SSCCE format.
SSCEE is also impossible as the functionality spans over about 10 classes We did not ask for your application, we asked for a SSCCE. The whole point of a SSCCE is to simplify the 10 classes into a single class and maybe an inner class for the editor to make sure you haven't made a silly mistake that is hidden because of the complexity of your real application.
