Problem About Focus transfer in swing JTable Cell

Question

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?

Answer 1

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.
