I am using JTable to load messages, fetching from server.
I want
1) Table should not allow any editing.
2) click on any cell should select the row
3) mouse Double click implementation
4) setting background for the particular rows.
Thank you,
please reply
1) read the tutorial I gave you in your other posting. (basically you override the isCellEditable() method of JTable or the TableModel
2) this is the default behaviour
3) what does this mean
4) again not a lot of information. Is this based of some data contained in the row. If so then search the forum for my TablePrepareRenderer example. If this done randomly, then search the forum for my TableColor example.
I am preparing a system for my project and the system is "Email client" which get the messages from server and allows the operations on it.
So to show the messages in the tabular form I am using JTable.
SO I think u will be able to understand my need.
ref to 1) thank you for tutorial suggestion.
ref to 3) I want to open a new window on the double click of row.
When i double click the cell, it goes in editing mode but i don't want that.
And when cell get clicked then I want to show that the whole row is selected.
ref to 4) background color is based on some flag associated with message like "unread" or "recent." and that also going to change dynamically.
thank you for reply
hope I will get some more info now.
3) See 1. Once the cell is not editable then when you double click the editor won't be invoked. So you add a MouseListener to the table and show your dialog on a double click. There are methods in the JTable API to convert the mouse point to a row and column in the table
4) See this posting for one way:

thank you sir for that mouse listener and the tablemodel help
One more question :
I have implemented my own datamodel class extending defaultdatamodel.
Fine with those editing problem.
One more problem arised is previously I was deleting row on request.
model.removerow() was getting called and the setting the model again.
I was removing at that time but now it's not working.
what need to be added.
thank you

Well, you have a bug in your code. The method from the DefaultTableModel works.
> Actually I want that font to be set for the data in the row of JTable.
Your requirement still isn't very clear. We don't know if the font changes for the entire row or only for certain cells.
This posting has two different approach for changing the font of a cell:

If you need further help then you need to create a [url http://homepage1.nifty.com/algafield/sscce.html]Short, Self Contained, Compilable and Executable, Example Program[/url] (SSCCE) that demonstrates the incorrect behaviour, because I can't guess exactly what you are doing based on the information provided.
Don't forget to use the [url http://forum.java.sun.com/help.jspa?sec=formatting]Code Formatting Tags[/url] so the posted code retains its original formatting.
messageTable = new JTable(model){
public Class getColumnClass(int column)
{
return getValueAt(0, column).getClass();
}
public Component prepareRenderer(TableCellRenderer renderer, int row, int column)
{
Component c = super.prepareRenderer(renderer, row, column);
try
{
Flags flags = messages[row].getFlags();
String[] uf = flags.getUserFlags(); // get user-flag strings
for (int i = 0; i < uf.length; i++) {
System.out.println("UserFlag : " + uf[i]);
}
}catch(Exception e){}
return c;
}
};

Not able to identify the reason..
thank you
