this.setLayout(new GridLayout(9,9));
for (int i=0; i<numbers.length; i++){
for (int j=0; j<numbers[i].length; j++){
numbers[i][j] = new TextArea();
this.add(numbers[i][j]);
numbers[i][j].addTextListener(new Performer(i,j));
}
}
}
class Performer implements TextListener {
int row;
int col;
Performer(int r, int c){
row = r;
col = c;
}
/*
* bogus returns false if there is no problem putting a number
* at a position
*/

for (int i=0; i<numbers[row].length; i++){

return true;
}
}

for (int i=0; i<numbers[row].length; i++){
if (i != row && snum.equals(numbers[i][col].getText())){
return true;
}
}
// scan the box to see ...
int [] istartA = {0,0,0,3,3,3,6,6,6};
int istart =istartA[row];

for (int i=istart; i<=istart+2; i++){
for (int j=jstart; j<=jstart+2; j++){
System.out.print("rc="+row+","+col+"ij="+i+","+j);
System.out.println(" "+snum+","+numbers[i][j].getText());
if (i!=row && numbers[i][j].getText().equals(snum)){
return true;
// numbers[row][col].setText("");
}
}
}
return false;
}
public void textValueChanged(TextEvent t ){
// get the value which just changed

if (bogus(row,col,snum)){

}

}
if (snum.equals(null)){
}
// check every blank block, and
//if it has only one
// possible answer, turn the background green.
//if it has no possible answer
// turn the background red
}
}
}
