Sorry but the code works but I do not understand why it works...
this is all code of the method
// this method is call when click add button from web interface.
private void addStock(String s)
{
// TODO
int row;
lastUpdatedLabel.setText(s);
final String
symbol=newSymbolTextBox.getText().toUpperCase().trim();
if (!symbol.matches("^[0-9A-Z\\.]{1,10}$"))
{
Window.alert("'" + symbol + "' is not a valid symbol.");
newSymbolTextBox.setText("");
return;
}
if (stocks.contains(symbol))
return;
row = stocksFlexTable.getRowCount();
stocks.add(symbol);
stocksFlexTable.setText(row, 0, symbol);
Button removeStock=new Button("X");
removeStock.addClickHandler(new ClickHandler() {
public void onClick(ClickEvent event)
{
System.out.println(symbol);
// why
when I click on button remove (removestock) the symbol variable
contains
the value corresponding to the table row?
int removedIndex =
stocks.indexOf(symbol);
System.out.println(symbol);
stocks.remove(removedIndex);
stocksFlexTable.removeRow(removedIndex + 1);
}
});
stocksFlexTable.setWidget(row, 3, removeStock);
newSymbolTextBox.setText("");
}
with best regards,
Angel
