Set default cell on JTable
How do I set the default cell on my JTable to be the first cell? Everytime my table gets the TAB or SHIFT-TAB key event, the last cell added to the table gets focus. Is there any way that I can change this to force cell(0,0) to always get focus on receiving the TAB or SHIFT-TAB key?
TableColumn tc = table.getColumnModel().getColumn(0);
tc.setMaxWidth(25);

Default cell values for column not properly saved in uir file in labwindows 2009 (9.1.0 427)?
I've run into a strange problem with the table control. Basically, even though I set default cell values for a particular column as numeric, when I try to add items to the list it tries to add them as strings, and returns an error message that it is expecting *char instead of int. Furthermore, when I open the uir file that contains the table in question in 2010, it appears as if the default cell values for that column are still set as strings, even though in 2009 when I open the uir file it shows as numbers. I tried converting the uir to C code, and sure enough the C code indicated that the column still is a string type.
I've gone ahead and made a small project to show the issue. If you open this project in labwindows 2009 and click on the table in the table_bug.uir, and edit default cell values for column 1, you will see that the cell settings have type as numeric and data type as int. When you run the project, however, it will fail with an error message saying that it is looking for a *char. When this same project is loaded into labwindows 2010, clicking on the table in table_bug.uir and edit default cell values (column 1) shows the type as string. When I change this to numeric (and change numeric attribute to int), this runs fine in 2010. I tried simply changing the uir in 2010, and then using it in 2009, but 2009 complains that the uir is from a newer version (understandable). If there is any workaround that would let me continue to use 2009 for the time that would be great.
Any help would be greatly appreciated.
thanks,

table_bug.zip 324 KBI opened the UIR in 2009 (but I have 2009 SP1) and it still showed that the default value for the first column was a string. I didn't have any problems changing it to a numeric int, and then building and running the project without error.
Here are a few things you can try:
1) Change the default value to a string. OK out of the dialog, re-enter the dialog, and change it back to Numeric int. Resave and see if the problem has gone away.
2) You said you get a ".UIR is from a newer version" error when opening the 2010 UIR in 2009. Does the UIR still open if you click okay? Often times this will work just fine. Assuming you don't have any problems with this, make a minor change to the UIR in 2009, such as moving the table to the left, and then back to the right and then re-save. See if your program works now.

HELP!! set the cell color in jTable
I need to set the color of a specific cell in jTable, but, I need to retain the old color in the jTable. It must not reset the whole table.
would anyone help me in this problem... PLSSSSS its urgentA flexible variation on this is to specify formatting options in the JTable's client properties:
// Use some sort of special "key" to indicate the cell and that you want to set the background color
String key = "background:" + row + "," + column;
table.putClientProperty(key, Color.green);You can then write a general table cell renderer that looks for these special formatting options and it doesn't disrupt your existing TableModel in any way:
public class FormattingTableCellRenderer extends DefaultTableCellRenderer
public Component getTableCellRendererComponent(JTable table, Object value, int row, int column, ...)
Component component = super.getTableCellRendererComponent(table, value, row, column, ...);
// See if the JTable specifies any properties to override the default format
Color backgroundColor = (Color)table.getClientProperty("background:" + row + "," + column);
if(backgroundColor != null)
component.setBackground(backgroundColor);
return component;
}Any custom cell renderers you have then simply need to extend FormatTableCellRenderer instead of DefaultTableCellRenderer.
It's very easy to add formatting options other than background, such as font, to the list of recognised attributes. You'll probably need to make some alterations to get it to recognise selection/focus but hopefully you get the idea.
Hope this helps. -
Dynamically set font in a JTable cell
Hi there,
i have a JTable, and a JTCombo box containing all the system fonts available. The JTable is made up of my own class called myCell which can be seen below. I have also implemented my own custom renderer. What i would like to do is when the user selects a new system font, the text that is then typed into the JTable to be of that font. If the system font is changed again, i would like any new text to be of the new font, and the old fonts remain the same (i hope that makes sense!) Anyway, im quite stuck about this - i have tried messing around with the cellrenderer but all the text in all the cells changes to the new font. Does anyone know how to do this? many thanks, Rupz
public myCell(int aRow,int aCol,Object someValue, TreeSet somecells, String aFormula){
row = aRow;
col = aCol;
value = someValue;
expression = aFormula;
references = somecells;
}First of all the Java standard for class names us to use upper case characters for the first letter of each word. So your class should be MyCell.
Now your MyCell class need to keep the Font as one of its properties. Maybe you would override the JTable getCellEditor(...) method such that if the Font property for the cell is null, then set the cell Font to the current default Font. The renderer would then use the Font from the cell when it is non-null. -
Setting Focus to a particular cell in JTable
Hi, can i know how to set the focus to a particular cell in JTable.
Say I have a table with 2 rows and 10 columns. The focus now is at position (1, 9) which is the last cell in the table. But I want to set the focus to (1, 3). How can i achieve this ? Pls help. ThanksOK. It's partially working. The right methods to use are setRowSelectionInterval and setColumnSelectionInterval. Jeanette was right. Mine didn't work because of a thread issue. I put the those two methods in a block such as:
SwingUtilities.invokeLater(new Runnable(){
public void run()
table.setRowSelectionInterval(tblLineItem.getRowCount()-1,
table.getRowCount()-1);
table.setColumnSelectionInterval(0,0);
Then it worked.
But after I finished editing the first cell of the newly created row and press ENTER, the selection went back to the cell that's next to the originally editing cell on the first(old) row, instead of staying at the current row and going to the second cell.
Can anybody shed a light on what I'm missing? -
How do you set defaults in pages such as font and moving between cells in a table?
How do you set defaults in Pages such as font and moving between cells in a table?
Default layout and styles can be set by setting up a sheet with your settings and saving as a user template (File > Save As Template). I don't know of a way to set defaults for moving between cells in a table.

How to set a cell editable at runtime for jtable
Hi evry body
i need to set a cell as editable during runtime and set some value for the cell and make it non editable after setting value
how can i do it? urgent help appreciated
regards
anilYou could override the methods isCellEditable(...) and setValueAt(...) in your JTable's TableModel to get the effect desired
// Assuming that each element of the array will be false initially
boolean[][] valueSet = new boolean[noRows][noCols];
public boolean isCellEditable(int row, int col) {
return !valueSet[row][col];
public void setValueAt(Object obj, int row, int col) {
super.setValueAt(obj, row, col);
valueSet[row][col] = true;

Setting two JTextFields inside JTable cell
hi,
I am really stick trying to figure out how to set two cells inside a JTable cell. This needs to be done because if there is a value already inside the cell then i want to drop another value - this new value should be displayed inside another cell but along with the other value already in the cell.
I assume that i would need to create two JTextFields.
But can anyone help me further please.That should be a simple issue of customizing table cell editor and renderer.
See tutorials. -
Friends,
I have a JTable with 5 rows and 4 columns now I want to set the Background color of cells as I select the set of cells it changes the background color.
the problem in the below code is I have to select the individual cells to set the bg. can anyone tell what I should add to set bg of all the selection + I am unable to see the cell selection.

I'm not sure why you're passing in an array of Color objects ... typically you'd either pick the color based on the value of the cell, or use standard colors.
Finally, your getTableCellRendererComponent() should check the isSelected argument, and use a different color to highlight the selection. -
How to make a cell in JTable a different colour?
Hi, i've been playing with JTables with a custom CellRenderer, which I'm trying to make so that in the JTable, when two values down a column are found to be the same, the back ground colour changes to something same (hoping that there is a way to randomize the colour values) the code i have atm is
In the main program :
find.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent ae) {
datahome = cC.data;
TableColumnModel colModel = cC.jtable.getColumnModel();
TableColumn column = colModel.getColumn(0);
column.setCellRenderer(new RedCellRenderer(new int[] {1,2}));
in the cellrenderer:
package packageSolo;
import javax.swing.table.DefaultTableCellRenderer;
import javax.swing.*;
import java.awt.*;
public class SetCellColour extends DefaultTableCellRenderer {
private int arrVerifyColumns[] = null;
public SetCellColour(int iTestColumns[]) {
arrVerifyColumns = iTestColumns;
public Component getTableCellRendererComponent(JTable table, Object value,
boolean isSelected, boolean hasFocus, int row, int column) {
this.setBackground(Color.RED); // All columns verified were empty - set
// our background RED
return this;
}any my problem is that this cellrenderer will change the column and not just the cell, i've tried to pass where the cell is (the x and y of the cell) to the cellrenderer, but there is no way for me to interpret this value in cellrenderer and set that cell to that colour i'm not sure if there is a cell model instead of column model and be able to pass that onto the cellrendererell after several tries, i have determined that it may be something wrong with that my jtable is part of a JPanel, that is attached to a container with scroll pane that is then added to a JFrame's center... and somewhere here it freezes the display...

if (finished == true) {
//JScrollPane scrollPane = new JScrollPane(jtable);
this.add( jtable, BorderLayout.CENTER );
Choose.setEnabled(false);
RunOnce = true;
}but upon start, and select start new table, the windows come up, but on where the large JFrame is and where the jtable is, nothing appears, and it acts like a screen cap and the thing just stucks like what is on the background of the computer... i think in all this linking i may have screwed something up, and the examples given were not designed for JPanels, but rather for JFrames... maybe i could implement all this into one class, since the buttons for choosing from load from file and all that can be in the first file as another JFrame, that is first visible, then when user chose one, something becomes visible, or something
but anyone knows how to fix all this? -
How to disable a particular cell in JTable ?
I having a problem on how to set disable a particular cell in JTable. At the first place to load the JTable, I want to set some of the cell to disabled, it only will run at the first time, is there anyway to do it ?
This is the function that disable/enable cells in JTables.
Are you looking for this?
public boolean isCellEditable(int row, int col)
if(((new Integer((String)(getValueAt(row,0)).toString()).intValue()>9))&&(col==1))
return true;
if(row!=4&&col!=5)
return true;
return false;
this metod belong to the TableModel function
and what I gave you is only an example of what you can do with it.
if it return false it disable and if true it enable the cell...but I think this you allready know!

Try
ds = oform.DataSources.DBDataSources.Add("OUSR")
oitem = oform.Items.Item("pm7")
omatrix = oitem.Specific
ocolumns = omatrix.Columns
ocolumn = ocolumns.Item("V_2")
ocombo = ocolumn.Cells.Item(r).Specific (r = row number)
LoadEroToCombo1(ocombo)
Catch ex As Exception
oapp.MessageBox(ex.Message)
End Try
End Sub
load to combo function is below
Public Sub LoadEroToCombo1(ByRef ocombo As SAPbouiCOM.ComboBox)
Dim rset As SAPbobsCOM.Recordset
Dim querystring As String
Dim rcount As Long
Dim rindex As Long
Try
rset = ocompany.GetBusinessObject(SAPbobsCOM.BoObjectTypes.BoRecordset)
querystring = "SELECT T0.U_NAME FROM OUSR T0"
rset.DoQuery(querystring)
rcount = rset.RecordCount
rset.MoveFirst()
ocombo.ValidValues.Add("0", "Select")
For rindex = 0 To rcount - 1
ocombo.ValidValues.Add(rset.Fields.Item(0).Value, rindex)
rset.MoveNext()
Next rindex
ocombo.Select("0")
rset = Nothing
System.GC.Collect()

Problem with select all cells in JTable
Hi guys! I get some problem about selecting all cells in JTable. I tried to used two methods:
1> table.selectAll()2> changeSelection(firstcell, lastcell,false,true)
firstcell:[0,0], lastcell[rowcount-1,colcount-1]
Result: only the first row selected when i use both methods.
Note: i set up the selection model as following:
this.dataSheet.setAutoResizeMode(JTable.AUTO_RESIZE_OFF);
this.dataSheet.setCellSelectionEnabled(true);
this.dataSheet.setRowSelectionAllowed(true);
this.dataSheet.setColumnSelectionAllowed(true);Thanks !What selection properity should be changed in order to enable selectAll() method work properly? Is there Any constraints? Here is the TableModel I am using. And i set up selection mode use the following code:
table.setAutoResizeMode(JTable.AUTO_RESIZE_OFF);
table.setCellSelectionEnabled(true);
table.setRowSelectionAllowed(true);
table.setColumnSelectionAllowed(true);
import java.util.Vector;
import javax.swing.table.*;
import javax.swing.JTable;
public class DataSheetModel extends AbstractTableModel{
private Vector data = new Vector();//Store data
private Vector columnNames = new Vector();//Store head
public DataSheetModel(){}
public DataSheetModel(Vector headVector, Vector dataVector){
if(headVector != null) this.columnNames = headVector;
if(dataVector != null) this.data = dataVector;
public int getColumnCount(){
return columnNames.size()+1;
public int getRowCount(){
return data.size()+1;
public String getColumnName(int col){
if(col==0) return "";
else return (String)columnNames.get(col-1);
public Object getValueAt(int row, int col){
if(col==0) {
if(row != data.size()) return String.valueOf(row);
else return "*";
else{
if(row != data.size()){
Vector rowVector = (Vector)data.elementAt(row);
return rowVector.elementAt(col-1);
}else return null;
public void setValueAt(Object value, int row, int col){
if(row != this.data.size()){
Vector rowVector = (Vector)data.elementAt(row);
rowVector.set(col-1,value);
this.data.set(row,rowVector);
this.fireTableDataChanged();
}else{
Vector rowVector = new Vector();
for(int i=0; i<this.getColumnCount()-1; i++) rowVector.add(null);
rowVector.set(col-1,value);
this.data.add(rowVector);
this.fireTableDataChanged();
public Class getColumnClass(int c){
return getValueAt(0,c).getClass();
public boolean isCellEditable(int row, int col){
if(col == 0) return false;
else return true;
public void setDataVector(Vector head, Vector data){
if(head != null) this.columnNames = head;
if(data != null) this.data = data;
}
