Hi,
PS: I'm using JasperReports 1.2.0 + Swing/JDK5.
I'd like to know:
1) How could I contrib with viewer.properties file, creating a
translating to pt-BR? There is only pt-PT available.
2) After this contrib, do I need to recompile all JasperReports changing
the default viewer.properties file to work it? Or is there a method to
call to setup the properties language file in runtime?
3) Is there some method to call saying to JasperViewer doesn't appear if
the ResultSet doesn't contain any data? I only want the message dialog
''The document has no pages.".
4) I had thought a way to show a Progress Bar when the report is
processing by a long way time. Then, I did a method like this:
JSplashTime splash = new
JSplashTime(cl,princ.getDirImagens()+"hourglass.gif","Processing report
...");
try {
try {
String SQL = "something..."
//
Statement stmt = princ.getconnLocal().createStatement();
ResultSet rs = stmt.executeQuery(SQL);
//=======================
// call Jasper with many code... only final 3 lines below for
simplicity...
try {
JasperReport jasperReport =
(JasperReport)JRLoader.loadObject(URLFile);
JasperPrint jasperPrint =
JasperFillManager.fillReport(jasperReport, parameters, new
JRResultSetDataSource(rs));
JasperViewer.viewReport(jasperPrint,false);
}
catch (JRException e) { e.printStackTrace(); }
}
//=======================
stmt.close();
return true;
} catch (Exception e) {
e.printStackTrace();
return false;
}
} finally {
splash.dispose();
}
Then, I made a JSplashTime (JWindow):
public class JSplashTime extends JWindow {
JLabel msgLabel;
String msgtime;
int cttime;
JProgressBar progress;
Timer timer;
/** Creates a new instance of JSplash */
public JSplashTime(ClassLoader cl, String icone, String msg) {
super();
getContentPane().setLayout(new
BoxLayout(getContentPane(),BoxLayout.Y_AXIS));
msgtime = msg;
//
JPanel panel = new JPanel();
panel.setBorder(new BevelBorder(BevelBorder.RAISED));
panel.setLayout(new BoxLayout(panel,BoxLayout.X_AXIS));
if (icone != null && cl.getResource(icone) != null)
panel.add(new JLabel(new ImageIcon(cl.getResource(icone))));
msgLabel = new JLabel(msg);
panel.add(msgLabel);
getContentPane().add(panel);
//
progress = new JProgressBar(0,100);
progress.setStringPainted(true);
progress.setIndeterminate(true);
getContentPane().add(progress);
//
pack();
setLocationRelativeTo(null);
setVisible(true);
//
cttime = 0;
int delay = 0; // delay for 5 sec.
int period = 1000; // repeat every sec.
timer = new Timer();
timer.scheduleAtFixedRate(new TimerTask() {
public void run() {
cttime++;
progress.setValue(cttime);
progress.repaint();
progress.getParent().validate();
progress.getParent().repaint();
System.out.println(cttime);
}
}, delay, period);
}
public void dispose() {
if (timer != null)
timer.cancel();
if (progress != null) {
progress.setValue(100);
progress.setIndeterminate(false);
}
super.dispose();
}
}
========================
But the JWindow (with labels and progressbar) doesn't repaint anything!
I don't know what can I do to solve this... The users become lost, they
don't know if the report is working or if the system is down.
Thanks for this help...
