Dear All Experts,
I am new to GWT and Visualization wrapper, I try out the example
SimpleViz.java shown in the GWT web. Unfortunately I can't get the
sample works,
......
public class SimpleViz implements EntryPoint {
public void onModuleLoad() {
// Create a callback to be called when the visualization API
// has been loaded.
Runnable onLoadCallback = new Runnable() {
public void run() {
window.alert("3");
Panel panel = RootPanel.get();
// Create a pie chart visualization.
PieChart pie = new PieChart(createTable(), createOptions());
pie.addSelectHandler(createSelectHandler(pie));
panel.add(pie);
window.alert("4");
}
};
// Load the visualization api, passing the onLoadCallback to be
called
// when loading is done.
window.alert("1");
VisualizationUtils.loadVisualizationApi(onLoadCallback,
PieChart.PACKAGE);
window.alert("2");
}
.......
I tried it out and it only print 1 and 2, not printing 3 and 4. It
seems that the Runnable object was not called when the package is
finished loading. Since there is no error and no return code, I can't
really judge by where it goes wrong,
if anyone has any idea, please shine some light on me. Was stucked in
this for 2 days...
Best Regards
Ferdi
