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.

Inserting cell inside JTable cell

Hi!
i want to insert another cell inside a JTable cell, so that they are both displayed.
Is it possible to do that.

I was thinking about something like the below. I have not tested it, so let me know if it works.
public class TwoCellTableCellRenderer extends DefaultTableCellRenderer {
     public Component getTableCellRendererComponent(JTable table,
            Object value,
            boolean isSelected,
            boolean hasFocus,
            int row,
            int column) {
          JPanel panel = new JPanel();
          panel.setLayout(new BoxLayout(this, BoxLayout.X_AXIS));
          panel.add(new JTextField(), null);
          panel.add(new JTextField(), null);
          return panel;
     protected void setValue(Object value) {
          // DO SOMETHING HERE TO PARSE YOUR TWO VALUES
public class YourTwoCellDataClass {
yourTable.setDefaultRenderer (YourTwoCellDataClass.class,
     new TwoCellTableCellRenderer());

Indeterminate JProgressBar inside JTable cell

I am able to put a JProgressBar inside a JTable cell, via a custom renderer to do so, however, I am unable to make the progress bar show the indeterminate animation. Any ideas? I calledbar.setIndeterminate( true ); and it doesn't seem to want to show. Is the JTable preventing it?
(should I include more of my code?)

Your JProgressBar is used to render the table cell only when that cell of the JTable needs to be rendered and the JProgressBar has no say in this.
I don't know why you would want to do this but to do this I would set up timer that fired a tree model event to say that the content of the cell had changed. This would trigger the cell to be re-painted. I think, but I can't be sure, that you will not be able to use
bar.setIndeterminate( true );
You may have to craft your own progress bar to make this easy.

Combobox Autocomplete editor inside Jtable cell

I have a custom combobox editor which supports the autocomplete feature as follows:
as soon as the user keys in any character, this editor searches for the item that starts with keyed in character. This item is displayed in the editor text field and the combobox popup is set to visible and the this item is set to selected.
this editor works fine when standalone. but the popup fails to become visible when this combobox is used as an celleditor inside jtable. infact the focus is lost from the entire table.
can anyone suggest the possible reason (and solution if possible).
following are the code snippets for the same: -
     private TableCellEditor addCellEditor() {
          final JComboBox myJComboBox = new PIComboBox();
          myJComboBox.setModel(new DefaultComboBoxModel(// some data model //));
          //change the size of popup window

You need to create a custom CellEditor which will prevent these problems from occurring. The explanation behind the problem and source code for the new editor can be found at Thomas Bierhance's site http://www.orbital-computer.de/JComboBox/. The description of the problem and the workaround are at the bottom of the page.

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:

If you need more info, please say so.
Thanks.

My mistake... It worked fine. The cell span code was malfunctioning. Thanks anyway.

JTable inside JTable cell

Hello. I'm trying to see if it's at all possible to have a JTable inside a JTable cell. I tried modifying those 'JButton inside JCell' examples, to no avail - it seems I didn't actually grasp the idea.
so anyway - did anyone ever do that? have a table inside a table? anyone can point me in the right direction?
thanks.

There are row height issues as well, especially if the rows/columns of the inner tables are variable. The getValueAt() method will require some thought. What is the value associated with all the cells in the inner table?
All in all, this is doable, but may not be desirable.

Setting the foreground in JTable cells conditionally.

I have a JTable which contains two columns adjacent to each other, both containing numbers (Floats).
If the number in the cell at a given row of column2 is greater than the number in the corresponding cell of column1, I want to set < row, column2 >'s text/foreground to red.
i.e.: If 0, 2 value > 0, 1 value: Set 0, 2 foreground to red
Also, I want to do this for all the cells in the second column whose values meet the criterion, simultaneously.
My question:
Am I right in assuming that this is a routine task in Java, and that there are well established ways of doing this?
If so, can anyone post or point me to some example code? If this is a wheel, I would hate to reinvent it.
Many thanks in advance.

karen,
I suggest you just make the whole cell the "select" colour, especially if it's a background colour... it gives the user a better impression of what it will look like in the "whatever".... even if you think it doesn't look so good "in itself".
The trick, is to use contrastingly dark or light forground colour.
If you really must have small region to the left containing a text colour then just make it another column in the table.

super(new javax.swing.JTextField());
this.editorComponent = new javax.swing.JTextField();
//this.setClickCountToStart(1);
ths is the source code to insert a new row in the JTable:
private void AddRowsinTable(){
int row = JTable.getRowCount() - 1;
JTextField[] newrow = CreateRow();
this.DefaultTableModel.addRow(newrow);
private JTextField[] CreateRow()
JTextField[] newrow = {this.JTextField0, this.JTextField1, this.JTextField2, this.JTextField3, this.JTextField4, this.JTextField5, this.JTextField6};
return newrow;

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.

Inputverifier+Jtextfield inside JTable

I've got an application which a JTable.
Inside the JTable I've got a JTextfield for editing the fisrt column
jTable1.getColumn("First" ).setCellEditor( new DefaultCellEditor( mytextfield ) );
The JTextField has a InputVerifier
This InputVerifier is called when I try to click outside the JTextField
But The JTextField lost the focus always.
What should I do to keep the focus on the JtextField ?
The problem is only when the JTextfield is inside the JTable, if the JTextField is outside then the focus works fine.
Thanks.

Hi,
Create your own editor which implements TableCellEditor and let the stopCellEditing() method
have a logic like this:
public boolean stopCellEditing()
      if (selectedEditor == stringEditor)
         boolean valid = textField.getInputVerifier().verify(textField);
         if (!valid) return false;
      return selectedEditor.stopCellEditing();
   }

In that first column has jcheckbox values which are there because of the tabledata has firstcolumn values as boolean, to know the no of checks in jcheckboxes in jtable, there is count variable which needs to be dynamic. When i first check the box the variable that i have set to know the check i.e count increases by one, then next jcheckbox if i check then count goes to 2, but real problem is when i do some 2 events on same checkbox then ie. if i check the jcheckbox , the count increases but after that the jcheckbox doesnot listen to events fired. Any help is appreciated

The example from above shows how to add Objects to a table. If you want a column of checkBoxes then simply replace the Objects in one of the columns with:
new Boolean(false)

Is there some way to set focus on a JTable Cell?

Hi,
I have used JDK6 with a JTable that has some cells not-editabled and others editable.
Then, when the user types TAB key, I would like to change to next editabled cell, jumping out the not-editables. Is there a way to do this?
Thanks

Theoretically you could modify the FocusTraversalPolicy but I've never done that.

JTable inside JTable cell: drag and drop

Hello. I've table (let's call it ParentTable), which cells contain other table (NestedTable). NestedTable recieves all events (I can move cursor, select cells by mouse, scroll table). ParentTable have enabled Drag nad Drop (D'n'D). When no cells in NestedTable are selected D'n'D works fine. When I select some cell in NestedTable, D'n'D does't work � it forbids the operation. I think this is because NestedTable recieves D'n'D events, but D'n'D is disabled for it. How can I work around this? I don't want to enable D'n'D for each NestedTable (there are several reasons for this).
The question is � can I pass to NestedTable all events, except of D'n'D ones?

Yes, I use custom cell renderer and cell editor for ParentTable, which returns NestedTable.
DnD turned on for the ParentTable, so when the NestedTable is active (some cells selected in it) it receives DnD events, which are turned off for it, and DnD doesn't work.
Possible solution is to turn DnD for NestedTable (not for ParentTable), and i'll do this if it is impossible to make it work in current configuration.
So the question is � is this possible do not pass DnD event to NestedTable ?

JTextField/JTable-cell Button

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:
