Dialog box not allowing user input?
Well im hoping someone can figure this out and i didnt see any other problems similar to this so hopefully its not a repeat...anyways here's my problem.
When i use JOptionPane.showInputDialog("What's your name? "); everything shows up just fine but I can't input any text.
my coding is fine - straight from the book - but is there anything that could be causing this problem?

Re: Dialog box not allowing user input?
With out the code, it appears to me you are using a "Message" dialog box. If your looking for input dialog as text check this demo out.
Re: Dialog box not allowing user input?
ok so i just ran that demo and everything worked fine...except i still couldnt actually input an answer in the text box? it was responding cuz i could interact with the dialog box just not input any text.
Re: Dialog box not allowing user input?
As william said, it is difficult to comment on a problem specific for a piece of code without the code itself. We can guess - mine being does the text box have focus? But just guesses. Please post an SSCCE that demonstrates the problem.
Re: Dialog box not allowing user input?
its not the coding thats the problem ...its super simple coding its something with my computer but anyways here's my code:
import javax.swing.JOptionPane;
public class NameDialog
{
public static void main (String [] args)
{
String name = JOptionPane.showInputDialog("What is your name?");
String message = String.format ("Welcome, %s, to Java Programming!", name);
JOptionPane.showMessageDialog (null, message);
}
}
thanks so far by the way....hopefully we can get it figured out.
Re: Dialog box not allowing user input?
Does a blinking cursor show up in the text box? If not, when you click in the text box does the cursor appear?
Re: Dialog box not allowing user input?
no when i click in it nothing happens at all...i can still click "OK" or "cancel" but just not insert text - - no cursor ever
Re: Dialog box not allowing user input?
Strange. What OS? JDK/JRE version?
Re: Dialog box not allowing user input?
windows 7 64 bit
java version "1.6.0_20"
OpenJDK Runtime Environment (IcedTea6 1.9.10) (rhel-1.23.1.9.10.el5_7-x86_64)
OpenJDK 64-Bit Server VM (build 19.0-b09, mixed mode)
Re: Dialog box not allowing user input?
While I don't know much about all those version numbers, the output - if this is from just calling 'java -version' on the command line - doesn't look right (the 'rhel' looks like redhat linux eg. a linux version on windows?). My suggestion would be to reinstall the JDK and JRE from oracle, quadruple checking to make sure the correct OS is chose.
Re: Dialog box not allowing user input?
Yea i did that but now how do i control the precedence of which my computer uses java - make it use the new version?
Re: Dialog box not allowing user input?
Yes. Set the PATH to the newly installed version:Originally Posted by michaelgilbert

Re: Dialog box not allowing user input?
ok i get the same dialog box but still cant insert text --- i just compiled it using
../src/jdk1.7.0_01/bin/javac and ran it with ../src/jdk1.7.0_01/bin/java
instead of completely changing the classpath i just used the new java's bin folder to run it which essentially would do the same thing as changing the classpath right? anyways i still cant change the text
