Using Google Visualization in GWT 2.0
- by nick
I'm working on learning GWT (total newb) and have a question regarding the Visualiztion API provided by Google. This page:
http://code.google.com/p/gwt-google-apis/wiki/VisualizationGettingStarted
Describes getting started with a pie chart (which is what I need). However I'm trying to do this in a composite UI using UiBinder. To that end I don't know how to handle the callback correctly that is shown:
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() {
Panel panel = RootPanel.get();
// Create a pie chart visualization.
PieChart pie = new PieChart(createTable(), createOptions());
pie.addSelectHandler(createSelectHandler(pie));
panel.add(pie);
}
};
// Load the visualization api, passing the onLoadCallback to be called
// when loading is done.
VisualizationUtils.loadVisualizationApi(onLoadCallback, PieChart.PACKAGE);
}
My First assumption is this would go in the UiBinder constructor, correct? Yet this assumes that I want to place the element in the RootLayoutPanel, and I don't. I can't see an elegant and obvious way of placing it in the binder. I submit that even this guess may be wrong. Any ideas from the experts?
