Hi all,
So I understand that onModuleLoad() method in the class that
implements EntryPoint is the method that basically initiates the GWT
web app. On this web app, I have some headers and metadata info, such
as the main title. However, I have a Table which dynamically pulls in
data from a local SQL DB. While I am able to successfully read from
the DB and display the data, I want the table to automatically reload
ever 5 minutes, which in return, refreshes the view if the DB changes
info.
I tried implementing a sleep timer function within the onModuleLoad()
within an infinite while loop but that does not work and the page
never completely loads because onModuleLoad() needs to finish being
called before the view gets loaded. Any ideas on how to implement an
automatic table or page refresher ever X minutes?
Here's the code in my onModuleLoad() function:
public void onModuleLoad() {
// Set alignment and size
DockPanel mainPanel = new DockPanel();
mainPanel.setSize("100%", "100%");
mainPanel.setVerticalAlignment(HasAlignment.ALIGN_MIDDLE);
mainPanel.setHorizontalAlignment(HasAlignment.ALIGN_CENTER);
final AppTableView tableView = new AppTableView();
final AppFrameView frameView = new AppFrameView();
// Add view modules to the page
mainPanel.add(appFrameView, DockPanel.NORTH);
mainPanel.add(appTableView, DockPanel.CENTER);
RootPanel.get().add(mainPanel);
while (true)
{
// This method pulls in data from the SQL db
and displays it
tableView.draw();
timer(500);
}
}
The tableView.draw() method is the one that pulls in data from the SQL
DB and displays it.
Thanks in advance,
-I.
