I tried to open a TitleAreaDialog as the main application dialog. As you=
=

see in the source code below, I tried different ways, but there was no =

success.
The MessagBox sample worked ver well - so I have no idea why the =

TitleAreaDialog doesn't work.

I got a heavy error, the JVM launcher (java 1.4) gives an error window -=
=

"fatal exceptionn occured. Program will exit"
and within the eclipse workbench I can read the message
"java.lang.NoClassDefFoundError: org/eclipse/core/runtime/IStatus
at Main.main(Main.java:25)"
The line concerned by this is
"TitleAreaDialog dlg =3D new TitleAreaDialog(new Shell());"

When I confirm the message window of the JVM launcher, eclipse closes =

itself.


public class Main
{ public static void main(String[] args)
{ //Display display =3D new Display();
//Shell shell =3D new Shell(display);
//shell.setSize(500, 500);
//shell.open();
=

TitleAreaDialog dlg =3D new TitleAreaDialog(new Shell());
//dlg.create();
dlg.setTitle("Test");
dlg.open();
=

//shell.dispose();
/*MessageBox m =3D new MessageBox(new Shell());
m.setMessage("Hello, World");
m.open();*/
}
}

Another question: I found documentations about the classes and hierarchi=
es =

provided by the Eclipse project. However, I didn't find any documentatio=
n =

how to use these classes in small und easy-to-understand examples (see m=
y =

try of a source code above). Are there any good onlinedocumentations ?
