here is my simplied code. I create a label and a flextable. the label
is updated every 300ms. This page make my computer's CPU go up to
100%.
public void onModuleLoad() {
final Label dateLabel = new Label();
final FlexTable flextable = new FlexTable();
RootPanel.get("errorLabelContainer").add(dateLabel);
RootPanel.get("errorLabelContainer").add(flextable);
for(int i =0;i<600;i++)
{
flextable.setWidget(i, 0, new Label("test"));
flextable.getFlexCellFormatter().setStyleName(30, 10, "demo-
table-cell");
for(int j =0;j<300;j++)
{
flextable.setWidget(i, j, new Label("test"));
flextable.getFlexCellFormatter().setStyleName(30, 10, "demo-
table-cell");
}
}
final Timer schedule = new Timer() {
public void run() {
Date currdate = new Date();
String date =
DateTimeFormat.getMediumDateTimeFormat().format(currdate);
dateLabel.setText(date);
schedule(300);
}
};
schedule.schedule(300);
}
