of course) and sums the values in the row's total column. The grand total for the
timecard is then displayed at the lower-right corner of the UI.

private void totalGrid() {

double grandTotal = 0.00;

for (int row=1;row<flexEntryTable.getRowCount();row++) {

Label rowTotalWidget = (Label) flexEntryTable.getWidget(row,

10);
double rowTotal =
Double.parseDouble(rowTotalWidget.getText());

grandTotal = grandTotal + rowTotal;

}

;

totalLabel.setText(NumberFormat.getFormat(".00").format(grandTotal));

}

At this point your application's basic functionality is in place. The next couple of
chapters will deal with authentication and persistence, so this is a good time to take a
look at the entire code in the TimeEntry.java file (Listing 5-1).
