Showing splash screen while loading...
Hi,
I'd like to show a splash screen while the application is loading (setting up hibernate session etc.) - here is my main method which is loading hibernate and starting up the application:
publicstaticvoid main(String[] args){
java.awt.EventQueue.invokeLater(new Runnable(){
publicvoid run(){
MdbCheckerApp app =new MdbCheckerApp();
app.initializeLookAndFeel();
// preload Hibernate session
HibernateUtil.getSession();
// login successful
// if (app.login()) {
new MdbChecker().setVisible(true);
// }
}
});
HibernateUtil.closeSession();
}
How do I show my splash screen while simultaneously loading the hibernate session?
Thanks in advance
- Stephan

However, I'm not quite sure on how to proceed...
public static void main(String args[]) {
final TestForm tf = new TestForm();
tf.showSplash();
tf.runInitializer(new Runnable() {
public void run() {
try {
Thread.currentThread().sleep(3000);
} catch (Exception e) {}
tf.hideSplash();
}
});
}
public void runInitializer(Runnable r) {
Thread t = new Thread(r);
t.start();
}
public SplashScreen showSplash() {
// if a splash window was already created...
if(splash != null) {
// if it's showing, leave it; else null it
if(splash.isShowing()) {
return splash;
} else {
splash = null;
}
}
splash = new SplashScreen(null, true);
centerComponent(splash);
splash.show();
return splash;
}
public void hideSplash() {
if (splash != null) {
splash.dispose();
splash = null;
}
}
I'm wondering why I do only see the splash screen (I was hoping that the splash screen would be disappearing after 3 seconds).
Here is the code of my splash screen:
public class SplashScreen extends javax.swing.JDialog {
/** Creates new form SplashScreen */
public SplashScreen(java.awt.Frame parent, boolean modal) {
super(parent, modal);
initComponents();
setLocationRelativeTo(null);
}
/** This method is called from within the constructor to
* initialize the form.

The only way I got it to work was calling the splash screen before calling invokeLater(). Otherwise the JWindow gets gray.
public static void main(String[] args)
{
// Splash screen s funciona se for exibida antes de invokeLater()
SplashScreen.getInstance().start();
SGPersistence.setPersistenceUnit("AutorizadorOnline");
SplashScreen.getInstance().finish();
java.awt.EventQueue.invokeLater(new java.lang.Runnable()
{
public void run()
{
SGUtil.setLookAndFeel(SGUtil.getCompactMetalLookAndFeelClassName());
// Exibe o formulrio de login
new LoginForm().setVisible(true);
}
});
}
}
In my case, SGPersistence.setPersistenceUnit() starts Hibernate
