Problem with JTable in a JScrollPane

Hello all,
I have a problem using JTable, that the number of columns is very big,
and the JScrollPane shows only vertical ScrollBar, isn't there any way to show a horizontal ScrollBar, to show the other columns without being bunched.
Thanks in advance.

Selection Problem with JTable

Hello,
i have a selection problem with JTable. I want to allow only single cell selection and additionally limit the selection to the first column.
I preffered the style from MS Outlook Express where you can select the email accounts to edit.
It is a table like this:
Account name |   Type |   ...
--------------|---------|---------------------
Hotmail       |   POP3 |
GMX           |   IMAP |The selection should be only avaibable at 'Hotmail' or 'GMX' - not at 'POP3', 'IMAP' or as complete row selection.
Please help me!
Thanks.

Colum Resizing problem in JTable

HI All,
I am facing a problem with JTable while resizing the colum. when user clicks and drags to resize a column, the column width increases continuously till the mouse button is released. I am sure this sounds like a vague description,
(eg)
when I click on a column boundary and drag, the column width is getting increase beyond where the cursor of the mouse is. In a normal table, when I click and drag, the column resizes to the size that I have the mouse position at, and gets set to the width when I release the mouse. But right now, when I click the mouse and drag to say a width of 50 from 10, it is still increasing beyond 50 and stops when I release the mouse at about 100 or higher. I hope this is a clearer explanation.
In Java 1.2, it works fine. but in java 1.4...
If Anyone knows, please let me know
Advance thanks for any comments and suggestion..
Best Regards,
Muthu

I solved this problem... Problem is getPreferredSize() method. I override this method
Thank u for ur suggestion..
Best Regards,
Muthu

Don't forget to use the Code Formatting Tags so the posted code retains its original formatting. That is done by selecting the code and then clicking on the "Code" button above the question input area.
The problem is that the size of the frame is greater than the size of the table so the widths of all the columns get adjusted after you specify the original default size.
Your code should be something like:
typeTable.setPreferredScrollableViewportSize(typeTable.getPreferredSize());
JScrollPane typeTableScrollPane=new JScrollPane(typeTable);
mt.pack();
mt.setVisible(true);Or you might be able to use my [Table Column Adjuster|http://www.camick.com/java/blog.html?name=table-column-adjuster] which will resize the columns automatically.

Hi!!! A Problem in JTable

HI,
I have a problem in JTable.I have a Jtable and a button named validate.My JTable first displays a set of rows and colums.if we name the colns as a,b and c. when i click the validate button i will take the values of a1 and b1 and do some validations. If it is in correct position then the row remains as it is else i will change the value of b1 to a1 position and vice versa. This happens in a loop till the end and the data vector of the table gets changed accordingly.Now the problem is suppose if there are 10 rows and the value changes in row 1,5,7 thn i need that rows alone to be colored while the button ends its action.Finally the JTable should be viewed as row 1,5,7 colored and others in their default color....
Please help me...

You will have to create your own Renderer or use a table like JXTable from swing labs that allows highlighting.

Problems with JTable

Hi All,
I am facing some problems in JTable :
1) How to remove all lines between cells, neither i should have column nor row lines....there should not be any lines between any cell at all.
2) If i select a perticular cell, complete row is getting selected with a blue background, that should not happen at all.....row should not get select....
3) How to make a cell non editable.
Regards,
Ravi

1) Read the API. Check out the set??? methods until you fine what you want
2) Read the API. Check out the methods that deal with row and column selection
3) Override isCellEditable(...) method of JTable or DefaultTableModel

JCheckBox clicking problem in JTable

Hi,
I have a column of JCheckBox in a JTable. The JTable is only used to layout the controls(for lagecy reason). The JCheckBox has an item change listener attached. The problem is that OCCASIONALLY when the JCheckBox[i] was clicked, the debug in itemStateChanged show the source object was NOT JChechBox, it was JCheckBox[i+1] or JCheckBox[i-1]. In other word, it was the check box in the previous or next row changed state.
Has anybody experienced similar problems? Is it a problem of JTable dispatching mouse click event?
How to solve the problem?
Thanks

I'm not sure why you get the results you do, but instead of adding a change listener to the JCheckBox you could add a TableModelListener to the TableModel. This will fire an event whenever any data is changed. This thread shows a simple example:
http://forum.java.sun.com/thread.jsp?forum=57&thread=425540

Cell Editor Problem in JTable

I have a problem using JTable. I have a requirement like each specified cell will have different editors like JtextField or Jcombobox as per some condition. I am building the rows at run time. Number of rows may vary as per condition.
can anyone guide me what to do?
thanks

Override the getCellEditor(...) method to return the appropriate editor.

Another problem with JTable

Hi,
I have encountered a problem with JTable, i am trying to display some 15 columns and their values , one of the columns value is null, then the JTable is not displaying its value from this column(which is with null value) onwards.
Can anybody assiss me in this matter.
Regards
khiz_eng

I don't know If I can fix your problem, but
I know just that it works on my PC.... It's very very
slow... I don't know how to insert PageSetUp option... I have to study the problem.....
However I don't think it's a hard problem....
I want ask to you if you have found some problems when you are in Editing mode in a cell.....
in the jdk1.2 version I could save while was in editing mode using the editingStopped method.
It permit to update all data .... also the data in the cell I was editing.
in the jdk 1.3 if I use this method It doesn't work properly... It maybe destroy the content object in the Cell..... because I'm able to print all the table except the editing cell (it throw an exception...)
What's changed????
I don't know...
Can u help me?

A problem with JTable

Hi !
I have a problem with JTable - would like to use this component as a simple list of rows taken from a database : don't want to be able select or set a focus to a column - want only to be able select and set focus to a row ( just like in the menus). How to disable "focusability" for a cell with JTable ? Could You help me ?
thnx in advance

The Border is changed by the renderer, depending on whether the cell has focus or not. So you will need to create custom renderers without a Border. Something like:
class NoBorderRenderer 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);
          setBorder(null);
          return this;
}

Problem with JTable and JPanel

Hi,
I'm having problems with a JTable in a JPanel. The code is basicly as follows:
public class mainFrame extends JFrame
        public mainFrame()
                //A menu is implemeted giving rise to the following actions:
                public void actionPerformed(ActionEvent evt)
                        String arg = evt.getActionCommand();
                        if(arg.equals("Sit1"))
                        //cells, columnNames are initiated correctly
                        JTable table = new JTable(cells,columnNames);
                        JPanel holdingPanel = new JPanel();
                        holdingPanel.setLayout( new BorderLayout() );
                        JScrollPane scrollPane = new JScrollPane(holdingPanel);
                        holdingPanel.setBackground(Color.white);
                        holdingPanel.add(table,BorderLayout.CENTER);
                        add(scrollPane, "Center");
                        if(arg.equals("Sit2"))
                                if(scrollPane !=null)
                                        remove(scrollPane);validate();System.out.println("ScrollPane");
                                if(holdingPanel !=null)
                                        remove(holdingPanel);
                                if(table !=null)
                                        remove(table);table.setVisible(false);System.out.println("table");
                        //Put other things on the holdingPanel....
        private JScrollPane scrollPane;
        private JPanel holdingPanel;
        private JTable table;
}The problem is that the table isn't removed. When you choose another situation ( say Sit2), at first the table apparently is gone, but when you press with the mouse in the area it appeared earlier, it appears again. How do I succesfully remove the table from the panel? Removing the panel doesn't seem to be enough. Help is much appreciated...
Best regards
Schwartz

If you reuse the panel and scroll pane throughout the application,
instantiate them in the constructor, not in an often-called event
handler. In the event handler, you only do add/remove of the table
on to the panel. You can't remove the table from the container
which does not directly contain it.
if (arg.equals("Sit2")){
holdingPanel.remove(table);
holdingPanel.revalidate();

Problem with JTable checkbox

In my table I have a column of checkboxes. If user clicks any checkbox, the program will first check for some condition and pop out a warning dialog saying that "the action will change the current mode. are you sure you want to continue?". If user select "yes", some action are taken and the checkbox should be selected. Now the problem is that after user select "yes", the checkbox is not selected. (Same as when you press your mouse at a checkbox and then drag it out the checkbox cell, the actions are taken but the checkbox is not selected.)
The code for the cell editor is as follows:
public Component getTableCellEditorComponent(JTable table, Object value,
           boolean isSelected, int row, int column) {
         if (value instanceof ComboString) { // ComboString
           flg = COMBO;
           String str = (value == null) ? "" : value.toString();
           System.out.println("+++++++ " + row+" : "+column+" flg: "+flg);
           return cellEditors[COMBO].getTableCellEditorComponent(table, str,
               isSelected, row, column);
         else if (value instanceof Boolean) {
           flg = BOOLEAN;
           Boolean check = Boolean.getBoolean(value.toString());
                      // promptContinue returns true for continue, false for return; inside it a dialog box is popped for user selection "continue or not"
                      if(!promptContinue()){
                            return null;
           return cellEditors[BOOLEAN].getTableCellEditorComponent(table,
               value, isSelected, row, column);


Thanks. But my problem is not with stopping the editor, but with continuing the editor. Following is the code of getCellEditorValue()
public Object getCellEditorValue() {
         switch (flg) {
         case COMBO:
           String str = (String) comboBox.getSelectedItem();
           return new ComboString(str);
         case BOOLEAN:
         case STRING:
           return cellEditors[flg].getCellEditorValue();
         default:
           return null;
            }I am not very sure whether it is the problem of cell editor or cell renderer, because it seems the code for continue condition is actually executed which is supposed to make the checkbox checked, but the result turns to be that the checkbox is not checked.

I get an exception
pls help

I included this statement only to check if it would print or not, because before that I tried printing the table without setting the size. Anyway, when I tried the same code under Windows it worked fine. Talking about platform independent...:-)

Selection problem in JTable

Hello everyone,
I've a JTable,which I'm rendering using my own renderer.When the background of any cell within the table is rendered,that particular row does not get highlighted on mouseclick.However,when only the foreground is set (without setting the background),the row is highlighted.Can anyone suggest anything on this problem.I want the row to be highlighted on mouse click even if the background of the cell is rendered.
thanx in advance.
J.C

Maybe u can use this, but you might want to extend your cell renderer.
[qouote from API docs]
setSelectionBackground
public void setSelectionBackground(Color selectionBackground)
Sets the background color for selected cells. Cell renderers can use this color to the fill selected cells.
The default value of this property is defined by the look and feel implementation.
