Problem About Focus transfer in swing JTable Cell
I open a JDialog in KeyPressed Event of Cell of the JTable,when the JDialog closed, I cannot set the Focus to next Cell in my code. the focus was set on the ToolBar(I don't write it in my code).
key pressed
void this_keyPressed(KeyEvent e) {
String text = this.getText().trim();
if(e.getKeyCode()==10 && text.trim().length()>0)
wzdlg = new JDialog();
Dimension dlgSize = wzdlg.getPreferredSize();
wzdlg.setLocation(0,0);
wzdlg.setModal(true);
wzdlg.pack();
wzdlg.show();
//When JDialog Closed,Focus move to next cell
//table.editAt(0,1); //cannot getFocus
//following cannot get focus too
Component comp = ((DefaultCellEditor)table.getCellEditor(0,1)).getComponent();
if (comp instanceof javax.swing.JTextField) comp.requestFocus();
Why? How Can I do?Try calling prepareEditor after your editCellAt method. It would be like
JTable.editCellAt(row, col);
JTable.prepareEditor(theTextFieldComponent, row, col);
Here, the text field component would be from the component editor. I would recommend you holding a reference than doing a getComponent. But, both may work. -
Turn a single jtable cell into 2 swing component
Hi, i'm trying to turn a jtable cell into two components, a jlabel and a jtextarea with the label on top of the textarea. Is that possible?
I can write my own renderer and editor and turn a cell into a combobox or textarea. But is it possible to put two renderers in a single cell?
thanksA JPanel IS-A Component so you could follow the procedure outlined in Sun's Tutorial and create a JPanel subclass that implements TableCellRenderer. For an editor the tutorial recommends subclassing AbstractCellEditor and implementing getTableCellEditorComponent() to return the panel containing your stuff.
I haven't done this, but it seems worth a try. If you get stuck the best (most knowledgable, quickest) help is to be had from the [Swing forum|http://forum.java.sun.com/forum.jspa?forumID=57].

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.

}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); -

Returning index of selected comp... jComboBox that is editing a jTable cell
so, i'm using an array to populate the choices of a combobox
public String[] progCodes = new String[]{"Standard","Restricted","Combined","Special"};which i'm using to edit a cell in a jtable
baseCatTable.getColumnModel().getColumn(4).setCellEditor(new DefaultCellEditor(new JComboBox(progCodes)));and when i get the value
System.out.println(baseCatTable.getValueAt(0, 4))i'd like to return the index of the selected item in the combo box instead of the text:
Standard
any suggestions?
Edited by: hansbig on Jan 24, 2008 5:04 PMsorry, but i'm using an IDE and it generates a lot of fluffy code.

Update JTable cells via setValueAt
Hello all,
I'm trying to implement a setValueAt method using an arrayList.....no success.What listeners should I have set up(For JTable or my table model)? I am new at this and I'm trying to update the JTable cells after a query from some db. Could anyone help?
When trying to change the a value in the table I get these errors:
"Exception occurred during event dispatching:

public Object getValueAt(int r, int c){

row = (Object[])cache.get(r);
return row[c];
else
return null;
}//getValueAtI would think that everone who starts off with JTable will have a couple of concept problems. I am also going thru this learnig curve. It looks to me ( the blind leading the blind etc) like your basic table has strange data in it. The problem is occuring when the JTable is trying to setup the data from the table model.
I don't think its anything to do with setValueAt.
I kept going back to TableMap, TableSorter and JDBCAdaptor examples and copying the code from them to come right.> I debug by putting a System.out .... in all the methods until I get to where the code is giving trouble.
Good luck [email protected]

Hi,
I have just started coding in Swings and would like to find out ways by which I can add JtextField in a JTable cell. Is there any?
Thanks in Advance.
CheenaThere sure is. The thing you're looking for is the cells TableCellEditor. Check out this tutorial, it will explain how to use CellEditors, you should have no diffculties adapting the example to your needs (otherwise just post again :-)

Way to listen for change in JTable cell?
I am having troubles trying to catch a key event while the user is entering text inside a given JTable cell (x/y location). The JTable only seems to manage String objects in it's cells so I can't place a JTextField in there with a KeyListener on it.
Currently, I can only get control of the application once the user has left the cell they are editing.
Does anyone have an example of a JTable 'cell KeyListener' scenario? At this point I want to see if I can print 'hello world' each time I type a character within a cell. Then I'll go from there....If you want to know when the contents of a cell have been updated you should use a TableModelListener.
If you want to know when a character is added/removed from the cell editor then you need to first understand how this works with a simple text field.
Typically you would use a DocumentListener to receive notifies of a change to the text field. However, within the DocumentEvent you wouldn't be able to change the text field as this notification comes after the text field has already been updated.
If you need to ability to intercept changes to the text field before they happen, then you would need to use a DocumentFilter. An example of using a DocumentFilter is given in the Swing tutorial on [url http://java.sun.com/docs/books/tutorial/uiswing/components/generaltext.html#filter]Text Component Features.
Once you get your regular text field working the way you want, the next step to create a DefaultCellEditor using this JTextField and use this editor in your JTable. The above tutorial also has a section on using editors in a table. -

} // @jve:decl-index=0:visual-constraint="29,25"If you have a different color for every cell in the table, then maybe it would be easier to store a custom Object in the TableModel that has two pieces of information:
a) the text to be displayed
b) the background color of the text.
Then you can write a custom renderer that uses both pieces of information to renderer the cell correctly.
Here is an untested example of what the custom renderer might look like:
class ColorRenderer extends DefaultTableCellRenderer
public Component getTableCellRendererComponent(
JTable table, Object value, boolean isSelected, boolean hasFocus, int row, int column)
super.getTableCellRendererComponent(table, value, isSelected, hasFocus, row, column);
CustomObject custom = (CustomObject)value;
setText( custom.getText() );
if (!isSelected)
setBackground( custom.getBackground() );
return this;

hi, i have a table and one cell is supposed to tell if an item is a file or a directory, and i want to display dir.png or fil.png depending on the type. this column in the table displays names of files and an icon indicating if its a directory or a file.
please how can i get started with this ?Try this example, hope this works well on your side.

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:
