Hello,
First, this is what I'm doing..
I have written a class I call AuthenticationManager. It keeps track of a
database name, user name and passphrase. It has a method called
getAuthentication() which opens a windows with three fields (one for
each of the values I listed). The window contains an ok and a cancel
button. The authMgr object is contained in my application's main JFrame
window.
From my main application frame I want to be able to call
authMgr.getAuthentication() and it should return true or false depending
on if ok or cancel was pressed to close the window.
At first, I just created a new window, and all was well, but when I ran
the application this code didn't do what I wanted:
----------------------
AuthenticationManager authMgr = new AuthenticationManager();
if(authMgr.getAuthentication())
{
System.out.println("Got authentication information: " +
authMgr.getDBName() + ", " + authMgr.getDBUser() +
", " + authMgr.getDBPass());
}
else
{
System.out.println("Didn't get authentication");
}
----------------------
Instead of waiting for an action (ok or cancel button), it immediately
printed "Didn't get authentication". Obviously, I'm new to Java
programming...
I did manage to get it working like I want my changing "extends JFrame"
to "extends JDialog" and added "setModal(true)" to the constructor.
Now I'm almost happy, there are just two issues. One major and one minor:
minor: Whenever I move the mouse-pointer over one of the entry fields,
it doesn't change to one of those 'I'-pointers - it just remains looking
like a standard arrow. This is what caused my major concern:
I get the feeling that what I've done is simply create an ugly hack -
that it works because of side-effects. I would like to know how this
should be done .. officially.
Any ideas? Do I need to provide more information? I can post code if
required.

Impossible to say for sure, because you did not include the
relevant code: the AuthenticationManager.

Still, it sounds like you're not waiting for the button press.
AuthenticationManager.getAuthentication() has to, in some point,
stop to wait for the button press event.

Works here for system and Xplat PLAF's using Java 1.5.0 under WinXP..
<sscce>
import java.awt.*;
import javax.swing.*;
/** Demonstrates the 'I' pointer for textual input for
the xplat and system PLAFs. */
public class WhereIsMyI {
/** Provide an argument to flip the PLAF. */
public static void main(String[] args) {
boolean bXPlatform = !(args.length==0);
try {
if (bXPlatform) {
UIManager.setLookAndFeel(
UIManager.getCrossPlatformLookAndFeelClassName() );
} else {
UIManager.setLookAndFeel(
UIManager.getSystemLookAndFeelClassName());
}
} catch (Exception exc) {
System.err.println("Error loading L&F: " + exc);
}
JDialog dialog = new JDialog((Frame)null, true);
Container container = dialog.getContentPane();
container.setLayout(new GridLayout(1,0) );
container.add(new JLabel("Put a String"));
container.add( new JTextField(10) );
dialog.pack();
dialog.setVisible(true);
}
}

It is a problem in you code (100:1).

Yes, an SSCCE

No, please, not 'code', so much as an SSCCE.
Oh, and it seems a modal JDialog is just what you need.
