dataGrid.addTablelistener {
public void onCellClicked(SourcesTableEvents sender, final int
row,final int cell) {
textBox.addFocusListener(new FocusListenerAdapter() {
public void onLostFocus(Widget sender) {
callDB(...);//pass whatever you want based on sender
}
});
textBox.addKeyboardListener(new KeyboardListenerAdapter() {
public void onKeyPress(Widget sender,char keyCode, int
modifiers) {
callDB(...);//pass whatever you want
}
});
});
private void callDB(...) {//must be outside of
dataGrid.addTablelistener
}
Please see the above code. If you are not satisfied with the above
code, you can use one class that implements FocusListener and
KeyboardListener.
