In working through the StockWatcher tutorial and I'm on "Add a button
to remove stocks from the stock list" under Step #5. While the
function works perfectly there is, for me, a logical disconnect. In
my mind, the code shouldn't work (perhaps it's my lack of
understanding of anonymous sub-classes):
// Add a button to remove this stock from the table
Button removeStockButton = new Button("X");
removeStockButton.addClickHandler(new ClickHandler() {
public void onClick(ClickEvent event) {
int removedIndex = stocks.indexOf(symbol);
stocks.remove(removedIndex);
stocksFlexTable.removeRow(removedIndex + 1);
}
});
stocksFlexTable.setWidget(row, 3, removeStockButton);
The "onClick" handler is executed when the removeStockButton is
clicked. The value of "symbol" comes from the newSymbolTextBox when
the stock is entered. So how does the onClick handler know the value
of "symbol" when the button is pressed?
Thanks,
Rob
