in my case, I've got several url but only one GWT module.
I put a javascript argument in the page (this is your server which put it in
the html page). This argument is read by my gwt module and I've got a switch
block to instanciate one widget which correspond to my page.
With this method, its is easy to deferred loading of javascript block.
Here is an example:
public class WidgetManager implements EntryPoint
{
private static final String VAR_ARGUMENTS = "args";
public static final String WIDGET_PANEL = "widgetPanel";
public static final String WIDGET = "widget";
public enum WidgetType
{
RegisterWidget, LoginWidget
}
/**
* This is the entry point method.
*/
public void onModuleLoad()
{
MainResources.INSTANCE.css_styles().ensureInjected();
// get all arguments
Dictionary args = Dictionary.getDictionary(VAR_ARGUMENTS);
String widgetArg = args.get(WIDGET);
if (!widgetArg.equals(""))
{
WidgetType widgetType = WidgetType.valueOf(widgetArg);
switch (widgetType)
{
case RegisterWidget:
GWT.runAsync(new RunAsyncCallback() {
public void onFailure(Throwable caught)
{
}
public void onSuccess()
{
addToRoot(new RegisterWidget());
}
});
break;
case LoginWidget:
GWT.runAsync(new RunAsyncCallback() {
public void onFailure(Throwable caught)
{
}
public void onSuccess()
{
addToRoot(new LoginWidget());
}
});
break;
}
}
}
public static void addToRoot(Widget page)
{
RootPanel rootPanel = RootPanel.get(WIDGET_PANEL);
DOM.setInnerHTML(rootPanel.getElement(), "");
rootPanel.add(page);
}
}
