(Java) inputDialog problem

[brad211987]

When I use JOptionPane.showInputDialog() the input dialog pops up behind any other windows on the screen at the time. Anyone know how to fix that? Not a huge problem but its irritating.

It should automatically focus itself. Can you post your code please?

        String list[] = {"100","400","900","1600"};
        String value = null;

        while(value == null)
        {
            value = (String)JOptionPane.showInputDialog(null,"How many cells do you want?",
                "John Conway's Game Of Life",JOptionPane.INFORMATION_MESSAGE,null,list,list[1]);
                
            if (value == null)
                JOptionPane.showMessageDialog(null,"You must choose a number.",
                    "ERROR",JOptionPane.ERROR_MESSAGE);
        }

This is the section of code that the input dialog is in. Do you think that it could possibly have something to do with the IDE? I had this problem when programming in highschool as well.

I downloaded another IDE and ran it with that and sure enough, the dialog pops up right in front.

Hmm why are you type casting the inputDialog box? The input given is a string by default. No need to type cast it.

[brad211987]

When I don't cast the inputdialog i get:

incompatible types - found java.lang.Object but expected java.lang.String


Still trying to figure that one out because I have never seen a showInputDialog() method that returns an object. Type casting is a remedy for now but still looking for why it needs it. Maybe it has something to do with using a list in the dialog.

[brad211987]

static Object 	showInputDialog(Component parentComponent, Object message, String title, int messageType, Icon icon, Object[] selectionValues, Object initialSelectionValue)

I was wrong, I finally got the docs to load up on this slow college net and found that it does in fact return an object. Thanks for reminding me to look that one up though, I had forgotten about that issue and now I get it.

I need to create an InputDialog using JOptionPane with two input fields an a large information message. How can I do this? Or may be it's better to create a JDialog?

Sounds like you will be using a JFrame or JPanel. Have you worked with either of these yet? The input won't be hard once you get the actual window working.
