Help needed urgently .. Please help...

Question

I am using JTable in my project where i am overriding the default editor to my own custom editor.
The problem is, when i am using tab key or mouse click, the cursor does not immediately move the next/clicked editable cell. I have to press the tab key twice to move to the next cell. After debugging i saw that the focus goes from the cell editor to the table and then on the second click to the next editor.
My project requires a single click/single tab key pressed to make the cells editable.
Please help..
Thanks in advance..

Hi!
I really have to get this Tab thing working.
This is what I have tried, and it works partially.
public boolean isManagingFocus()
return true;
public boolean isFocusCycleRoot()
return true;
* Captures tabs and moves focus to the next or previous cell, depending
* on whether the <Shift> key was also pressed (i.e. tab or back tab).
public void processComponentKeyEvent(KeyEvent e)
if ( (e.getID() == KeyEvent.KEY_TYPED) && (e.toString().toLowerCase().indexOf(",tab") >= 0) )
if (e.isShiftDown())
tabToNextEditableCell(BACKWARD);
else
tabToNextEditableCell(FORWARD); // tab
e.consume();
else
super.processComponentKeyEvent(e);
* Sets editing focus onto next editable cell.
* When moving forward, traverses cells from left to right then top to
* bottom
* @param direction FORWARD or BACKWARD
private void tabToNextEditableCell(int direction)
int x = getSelectedRow();
int y = getSelectedColumn();
//Added
clearSelection();
if ( direction == FORWARD && x < getRowCount() )
editCellAt(x+1, ATTRIBUTE_VALUE_COL);
else if (direction == BACKWARD && x >0)
editCellAt(x-1, ATTRIBUTE_VALUE_COL);
Let me describe what is happening..
When I click tab, it moves 2 rows down, The table still highlights the next cell, but since it is not editable, I cant do anything, when I click Tab it moves to the next editable cell, which means that if the current cell is editable the table highlight moves to the next cell (which is not editable), and on the next tab it starts editing the cell.
I dont know if I made too much sense... but I reallly need help with this.
