Image in a JTable cell
How can I put ImageIcon object in a JTable cell?
yes, I'mm trying :
ImageIcon icon = new ImageIcon("something.gif")
DefaultTableModel model = (DefaultTableModel)jTable1.getModel();
Object[] newRow = new Object[5];
newRow[1] = "I don't";
newRow[2] = "know, what";
newRow[3] = "I am doing"
newRow[4] = "wrong"
newRow[0] = icon;
model.addRow(newRow);
but icon doesn't show

}what wrong with this code..
ThanksIn summary, you have one or more columns for which the data must be wholly visible - correct? If you need all the columns to show the whole of their data, you are goinf to have to expand the table, otherwise you can expand a column with something like
myTable.getColumnModel().getColumn(whichever).setPreferredWidth(whatever); -

Multiple JButtons inside JTable cell - Dispatch mouse clicks
Hi.
I know this subject has already some discussions on the forum, but I can't seem to find anything that solves my problem.
In my application, every JTable cell is a JPanel, that using a GridLayout, places vertically several JPanel's witch using an Overlay layout contains a JLabel and a JButton.
As you can see, its a fairly complex cell...
Unfortunately, because I use several JButtons in several locations inside a JTable cell, sometimes I can't get the mouse clicks to make through.
This is my Table custom renderer:
public class TimeTableRenderer implements TableCellRenderer {
Border unselectedBorder = null;
Border selectedBorder = null;
public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected,
boolean hasFocus, int row, int column) {
if (value instanceof BlocoGrid) {
if (isSelected) {
if (selectedBorder == null)
selectedBorder = BorderFactory.createMatteBorder(2,2,2,2, table.getSelectionBackground());
((BlocoGrid) value).setBorder(selectedBorder);
} else {
if (unselectedBorder == null)
unselectedBorder = BorderFactory.createMatteBorder(2,2,2,2, table.getBackground());
((BlocoGrid) value).setBorder(unselectedBorder);
return (Component) value;
}and this is my custom editor (so clicks can get passed on):
public class TimeTableEditor extends AbstractCellEditor implements TableCellEditor {
private TimeTableRenderer render = null;
public TimeTableEditor() {
render = new TimeTableRenderer();
public Component getTableCellEditorComponent(JTable table, Object value,
boolean isSelected, int row, int column) {
if (value instanceof BlocoGrid) {
if (((BlocoGrid) value).barras.size() > 0) {
return render.getTableCellRendererComponent(table, value, isSelected, true, row, column);
return null;
public Object getCellEditorValue() {
return null;
}As you can see, both the renderer and editor return the same component that cames from the JTable model (all table values (components) only get instantiated once, so the same component is passed on to the renderer and editor).
Is this the most correct way to get clicks to the cell component?
Please check the screenshot below to see how the JButtons get placed inside the cell:
http://img141.imageshack.us/my.php?image=calendarxo9.jpg
If you need more info, please say so.
Thanks.My mistake... It worked fine. The cell span code was malfunctioning. Thanks anyway.

Is there any known efficient methods of creating the JTextField or JTable-cell Button as like in Forte's Component Inspector window where you click on the property value field and the value is displayed just left of a small button labelled "..." ie: [some text field with value][...] also referred to as the "ellipsis" buttons, or will most answers to this question simply describe the layout of a JField-JButton combination? The action from clicking on the [...] button aligned right of the JTextField simply invokes or displays a larger input interface in which upon completion of the entered data, returns the input to the related JTextField.
Thanks to anybody for any help with this, and perhaps in return, I may be able to answer any non-gui java questions, or some not so unfamilliar GUI questions.Hello StanislavL and Lutianxiong,
I remember asking this question some time ago, and the time has come again for me to seek this functionality. I have finally achieved the functionality and thought I would post the answer for anybody else. I had not realized that I had recieved a solution/reply to my original question as I come here to post the answer, and in fact, my solution does appear to be very similiar to your reply, StanislavL. As for you, Lutianxiong and other seekers of this info, here is my solution with a JFileChooser style input for the 3rd column which only shows gif,jpg and png files:

Hello -
I'm rather new to Java, so please excuse me if this is a simple question. For a project I am working on, I am attempting to deal with placing two icons in a single JTable cell. For the life of me I have no idea if this is even feasible, let alone how I would implement it. Originally I thought about attempting to overload the JLabel class (as this is what the JTable cell is based upon, if I'm not mistaken?) and allowing two icons to be placed per label.
Am I on the right track? Is this even possible? Any suggestions?
Thanks much.Please read the forum for JTable.
http://java.sun.com/docs/books/tutorial/uiswing/components/table.html
You will know that you canuse any component as CellRenderer, this component can have whatever you want (say 2 icons and 5 comboboxes)
here is short example that shows 2 icons in JTable

Putting icon in the Jtable cell
Can I put the Icon or image in the table cell.?
I am Using Jtable and default model for that.
Waht should be done to place the icon or image in particular cell which will be based on some condition check.
thank you
sumantRead the [url http://java.sun.com/docs/books/tutorial/uiswing/components/table.html#sorting]Table Sorting example. An icon is placed in the header to indicate the direction of the sort. They probably use a custom renderer since the header assumes the data for the headers is a String Object.

HI,
Here trying to populate the ImageIcon using JLabel in Jtable cell. For that I used DefaultCellRenderer. For implement the mouseListener to label I used the DefaultCellEditor. I am facing one problem here. After editing the label I selected the second row of the table, the first row image is not displaying. Can any one help on this issue?
public class LabelCellEditor extends DefaultCellEditor {
public LabelCellEditor(final JCheckBox checkBox) {
super(checkBox);
public Component getTableCellEditorComponent(final JTable table, final Object value,
final boolean isSelected, final int row, final int column) {
Color background = null;
background = ColorManager.SELECTED_ROW_BGCOLOR;
labelVal = (JLabel) value;
labelVal.setOpaque(true);
labelVal.setFont(FontManager.TABLE_DATA_FONT);
labelVal.setBackground(background);
labelPanel = new JPanel();
labelPanel.setOpaque(true);
labelPanel.setBackground(background);
labelPanel.setLayout(new FlowLayout(FlowLayout.LEFT));
labelPanel.setBorder(new EmptyBorder(5, 0, 0, 0));
labelPanel.add(labelVal);
return this.labelPanel;

Can not show the JCheckBox in JTable cell
I want to place a JCheckBox in one JTable cell, i do as below:
i want the column "d" be a check box which indicates "true" or "false".
String[] columnNames = {"a","b","c","d"};
Object[][] rowData = {{"", "", "", Boolean.FALSE}};
tableModel = new DefaultTableModel(rowData, columnNames);
dataTable = new JTable(tableModel);
dataTable.getColumnModel().getColumn(3).setCellEditor(new DefaultCellEditor(new JCheckBox()));
But when i run it, the "d" column show the string "false" or "true", not the check box i wanted.
I do not understand it, can you help me?
Thank you very much!
coral9527Do not use DefaultTableModel, create your own table model and you should implement the method
getColumnClass to display the boolean as checkbox ...
I hope the following colde snippet helps you :
class MyModel extends AbstractTableModel {
private String[] columnNames = {"c1",
"c2"};
public Object[][] data ={{Boolean.valueOf(true),"c1d1"}};
public int getColumnCount() {
//System.out.println("Calling getColumnCount");
return columnNames.length;
public int getRowCount() {
//System.out.println("Calling row count");
return data.length;
public String getColumnName(int col) {
return columnNames[col];
public Object getValueAt(int row, int col) {
return data[row][col];
* JTable uses this method to determine the default renderer/
* editor for each cell. If we didn't implement this method,
* then the last column would contain text ("true"/"false"),
* rather than a check box.
public Class getColumnClass(int c) {
return getValueAt(0, c).getClass();
* Don't need to implement this method unless your table's
* editable.
public boolean isCellEditable(int row, int col) {
//Note that the data/cell address is constant,
//no matter where the cell appears onscreen.
return true;
* Don't need to implement this method unless your table's
* data can change.
public void setValueAt(Object value, int row, int col) {
data[row][col] = value;
fireTableCellUpdated(row, col); -
Shading part of a JTable Cell dependent upon the value of the cell
Hi
Was hoping some one woudl be able to provide some help with this. I'm trying to create a renderer that will "shade" part of a JTable cell's background depending upon the value in the cell as a percentage (E.g. if the cell contains 0.25 then a quarter of the cell background will be shaded)
What I've got so far is a renderer which will draw a rectangle whose width is the relevant percentage of the cell's width. (i.e. the width of the column) based on something similar I found in the forum but the part I'm struggling with is getting it to draw this rectangle in any cell other than the first cell. I've tried using .getCellRect(...) to get the x and y position of the cell to draw the rectangle but I still can't make it work.
The code for my renderer as it stands is:
import java.awt.Component;
import java.awt.Graphics;
import java.awt.Graphics2D;
import javax.swing.JLabel;
import javax.swing.JTable;
import javax.swing.table.TableCellRenderer;
public class PercentageRepresentationRenderer extends JLabel implements TableCellRenderer{
double percentageValue;
double rectWidth;
double rectHeight;
JTable table;
int row;
int column;
int x;
int y;
public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected, boolean hasFocus, int row, int column) {
if (value instanceof Number)
this.table = table;
this.row = row;
this.column = column;
Number numValue = (Number)value;
percentageValue = numValue.doubleValue();
rectHeight = table.getRowHeight(row);
rectWidth = percentageValue * table.getColumnModel().getColumn(column).getWidth();
return this;
public void paintComponent(Graphics g) {
x = table.getCellRect(row, column, false).x;
y = table.getCellRect(row, column, false).y;
setOpaque(false);
Graphics2D g2d = (Graphics2D)g;
g2d.fillRect(x,y, new Double(rectWidth).intValue(), new Double(rectHeight).intValue());
super.paintComponent(g);
}and the following code produces a runnable example:
import javax.swing.JFrame;
import javax.swing.JScrollPane;
import javax.swing.JTable;
import javax.swing.table.DefaultTableModel;
public class PercentageTestTable extends JFrame {
public PercentageTestTable()
Object[] columnNames = new Object[]{"A","B"};
Object[][] tableData = new Object[][]{{0.25,0.5},{0.75,1.0}};
DefaultTableModel testModel = new DefaultTableModel(tableData,columnNames);
JTable test = new JTable(testModel);
test.setDefaultRenderer(Object.class, new PercentageRepresentationRenderer());
JScrollPane scroll = new JScrollPane();
scroll.getViewport().add(test);
add(scroll);
public static void main(String[] args)
PercentageTestTable testTable = new PercentageTestTable();
testTable.pack();
testTable.setVisible(true);
testTable.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
}If anyone could help or point me in the right direction, I'd appreciate it.

How to write an element in a JTable Cell
Probably it's a stupid question but I have this problem:
I have a the necessity to build a JTable in which, when I edit a cell and I push a keyboard button, a new Frame opens to edit the content of the cell.
But the problem is how to write something in the JTable cell, before setting its model. Because, I know, setCellAT() method of JTree inserts the value in the model and not in the table view. And repainting doesn't function!
What to do??
ThanksHi there
Depending on your table model you should normally change the "cell value" of the tablemodel.
This could look like:
JTable table = new JTable();
TableModel model = table.getModel();
int rowIndex = 0, columnIndex = 0;
model.setValueAt("This is a test", rowIndex, columnIndex);
The tablemodel should then fire an event to the view (i.e. JTable) and the table should be updated.
Hope this helps you -
How to select rows in the inner JTable rendered in an outer JTable cell
I have wrriten the following code for creating cell specific renderer - JTable rendered in a cell of a JTable.
table=new JTable(data,columnNames)
public TableCellRenderer getCellRenderer(int row, int column)
if ((row == 0) && (column == 0))
return new ColorRenderer();
else if((row == 1) && (column == 0))
return new ColorRenderer1();
else
return super.getCellRenderer(row, column);
ColorRenderer and ColorRenderer1 are two inner classes, which implement TableCellRenderer to draw inner JTable on the outer JTable cell, having 2 rows and 1 column each.
Now what is happening the above code keeps executing continously, that is the classes are being initialised continously, inner JTables are rendered (drawn) continously, and this makes the application slow after some time. It throws java.lang.OutOfMemoryException.
WHY IS IT SO??? I can't understand where's the bug..
Any advice please???
Moreover i want selections in inner tables and not on outer table, how can this be possible.
I am working on this since a long time but have not yet found a way out...With your help i have overcome the problem of continous repeatition.
The major problem which I am facing is, in selecting rows in the inner rendered JTables.
I have added listener on outer JTable which select rows on the outer JTable, hence the complete inner JTable which being treated as a row, gets selected.
The thing is i need to select the rows of inner rendered JTables,not the outer JTable.
How to go about it??
I have even added listener to inner rendered JTables, but only first row of every table gets selected.
Please help....
Thanks in advance. -

Can anyone show me how to add an image to a datagrid cell in actionscript?
I've added a sample of the code I have written already below. Any help would be much appreciated.

Scaling of images in a table cell
Hi,
I have an issue aboute the scaling of images in a table cell. The table layout is fixed but the images can vary. I tried to transform the images but every time the transformation matrix has a scaling != 1.0 the function results in an error.
The following code is used.
PageItem pi = myCell.getNthChildPageItem(0);
TransformationMatrix[] matrix = pi.transformValuesOf(kCoordinateSpacesInnerCoordinates.value);
TransformationMatrix scalemat = matrix[0].scaleMatrix(OptArg.makeDouble(0.5), OptArg.makeDouble(0.5));
Unit[] matValues = UnitUtils.createDouble(scalemat.getMatrixValues());
pi.transform(
enums.kCoordinateSpacesInnerCoordinates.value,
VariableTypeUtils.createEnumeration(enums.kAnchorPointCenterAnchor.value),
VariableTypeUtils.createUnitList(matValues),
OptArg.makeVariableType(VariableTypeUtils.createEnumeration( enums.kMatrixContentScaleValues.value ) ),
OptArg.noBoolean()
Any suggestions?

tomHi!
You may try to vary the settings for property "type"
navigation
function
reporting
result
If this does not help to solve your issue open a ticket at SAP Support.
There are several UIElements which show such a behaviour and you have no (documented) chance to change this.
Hope this helps.

Custom styles disappear in Smartview
Hi We have given some styles in data forms for HFM (color/ bold, etc) Though this appears rightly on the web, the same does not appear at all when the data form is opened using Smartview in Excel. In excel, it reverts to the standard HFM color code.
