Possible alternative to input dialog box

The program I'm creating would like to utilize the functionality of an input dialog box, however, I would like for the input dialog box to return a group of values instead of just one. As far as I can tell, the input dialog box can return a single String based an a group of values that I supply. However, the program I use would want the user to be able to select several of those values. Is there a way to have the input dialog box return a String[]? Perhaps there is another option that I'm not really aware of that can mimic the input dialog box functionality?

Hi,
You might create some complex JComponent (a JPanel containing lots of check boxes and text fields etc). Use that component as a message. Then, when the user clicks the OK button, investigate your complex component for all its values.

Trying to create an input dialog box, that will halt execution

I am trying to get a pop up dialog box to appear where the user will enter their name, after clicking OK or Cancel, i would like the code to continue executing. For example when i use the Alert.show("1");Alert.show("2");Alert.show("3"); it appears as 3,2,1. Is it possible to fire one alter at a time AFTER the user has clicked Ok.
Back to the originial question.
I am setting up a Pop up menu
var ret:String;
var Dialog:SimpleTitleWindowExample =SimpleTitleWindowExample(PopUpManager.createPopUp( this, SimpleTitleWindowExample , true));
ret = Dialog.Input //where input is just a public text for example
return ret;
^returns null.
I was hoping it would wait until it was closed to continue. I thought it would by setting the modal = true
Essentially I'm asking is there a way to halt execution until the user inputs some text? Doesn't have to utilize the PopUpManager.
Please help. I've spent 4 hours trying to tackle this. I even tried to do a DoEvent (Visual Studio) type loop until the button was clicked or variable was no longer blank.

I think you may alternately be able to listen for the removedFromStage event and react to that. In any case, you need some way of reacting to SampleTitleWindow closing (via an event listener), and only then trigger the next pop-up.

Input dialog question OK/Cancel Button

Hi there,
I�m busy with an application that displays an input dialog box on start up. It prompts the user for their name. This imput will then be used for a JLabel welcoming the user with their name. If no name is entered. The Jlabel will display �Welcone User�. Everythng works fine but when I press cancel on the input dialog box I get an error. Below is some code of what I�ve done so far.
Thanks,
Patrick.
String name = JOptionPane.showInputDialog(null,
          "Please enter your name",
          "Name input",
          JOptionPane.PLAIN_MESSAGE);
          welcome = new JLabel(name);
          if (name.length() == 0) {
               welcome = new JLabel("Welcome User");
          else if (name.length() > 0) {
               welcome = new JLabel("Welcome " + name);

The error is NullPointerException.
If the cancel button is pushed a null is returned.
Try this test instead
if ((name == null) || (name.length() == 0))
   welcome = new JLabel("Welcome User");
}

Java Dialog Box

How would you make a Data Input Dialog using Java? I am fairly new to Java and im used to programming with C# but for my school syllabus I have to use Java to make database... So how can I make an input dialog box to input like a set of data. I know how to use JOptionPane to input data one by one but how do I input a set of data using a dialog box?
thx

depends on how fancy you want to make it.
you can still use a joptionpane for your 'multiple' input:
(note: error handling seriously lacking)
import javax.swing.*;
import java.awt.*;
class Testing
public static void main(String[] args)
    JLabel nameLbl = new JLabel("Name:");
    JLabel addressLbl = new JLabel("Address:");
    JTextField nameTF = new JTextField(5);
    JTextField address1TF = new JTextField(5);
    JTextField address2TF = new JTextField(5);
    JPanel p = new JPanel(new GridLayout(3,2));
    p.add(nameLbl);p.add(nameTF);
    p.add(addressLbl);p.add(address1TF);
    p.add(new JLabel());p.add(address2TF);
    JOptionPane.showMessageDialog(null,p);
    System.out.println("Your name is "+nameTF.getText());
    System.out.println("Your address is:\n"+address1TF.getText()+"\n"+address2TF.getText());
    System.exit(0);
}

Input dialog help...

I cannot seem to find if there is a way to create an input dialog box that accepts a String as input but only has an 'OK' button and no 'Cancel' button.
It seems that the 'Cancel' button is put in by default. Is there any way to eliminate it or do I have to write my own class?
Edited by: gabel3469 on May 16, 2008 5:07 AM

the best is to impose the user to input with something like:
do
// prompt the dialog
while (userInput.equals("") || optionChosen = CLOSED_OPTION || optionChosen == CANCEL_OPTION);

How to disabled the input parameter dialog box in crystal reports 9

Post Author: Murtaza
CA Forum: General
Hi friends,I have got stuck with a weird problem. In my
crystal report, I have set up some input parameters. I am setting
values for these parameters somewhere inside code. But I don't
want to show the default input parameter dialog box. Under any case,
user should not see the ugly parameter dialog box that crystal
presents. Please suggest me how I can achieve
this. I cannot do this through code, because our environment does
not allow that. I have to do this in crystal reports viewer and
by setting some property of the crystal report object. But everything
must be done on UI, not through code. So, the solution should not be the following.
// step before step 1
// **** the line needs to refer to the report and be set before setting
ReportSource in the viewer to myReport
myReport.EnableParameterPrompting = False
Any help would be greatly appreciated. Murtaza

Hi Murtaza,
Unfortunately, I am not aware of any method to suppress the prompt for the input parameters, but still use them. It is truly a design-related issue for the report. The reason that the prompt appears is because the parameter it is prompting for is used in the report; in particular either the Group or Record Selection, or referenced in another formula.
The only way I can think of to not show the prompt, is to not use the parameter in the report. You did mention that you are setting the value of the parameter inside of the report -- are you doing this through using a formula? Perhaps you can just remove the parameter and only use the formula that you are setting the default values with.

Retrieve 4 inputs from one dialog box at a time

I have a Jframe and when I click a button I want it to open a new Jdialog box. I want 4 different input fields. Two will be for strings, 1 int, 1 double. But I can't get it to open up a dialog with all of those things. Will I have to accept them all as strings then convert them to double and int? and what will the code for 4 input fields in a dialog box look like? If you need more info just ask... And I'm using Netbeans, if this makes it easier.

You could design a custom JDialog or whip up something simpler with JOptionPane:
import java.awt.*;
import javax.swing.*;
public class JOptionPaneExample {
    public static void main(String[] args) {
        JPanel p = new JPanel(new GridLayout(2, 2));
        p.add(new JLabel("name:"));
        p.add(new JTextField(10));
        p.add(new JLabel("age:"));
        p.add(new JTextField(10));
        int result = JOptionPane.showConfirmDialog(null, p, "title",
            JOptionPane.OK_CANCEL_OPTION,
            JOptionPane.PLAIN_MESSAGE);
}

Unable to disable input field in modal dialog box

Hi All, I have a screen typed modal dialog box with a table control.
I want to disable field input in the table control when some conditions meet.
I write the following code in the PBO, but it's not working. The group1 has been set.
LOOP AT SCREEN.
       IF screen-group1 = 'DSP'.
         screen-input = 0.
         MODIFY SCREEN.
       ENDIF.
ENDLOOP.
Would anyone help me? Thanks in advance!

Hi,
Loop over table control and then modify the table control. Check the below threads for reference:

Hex input using user dialog box.

Hello
I am trying to use the user dialog box to input data. I want to input the data as Hex. format. however as I select the input to be a number, it takes as a decimal number and there seems to be no option where I can change it to a hex format. Any suggesstions as how to make this possible..
Thanks in advance.

You made me look. I had to try this on dialog controls for myself.
Place your control and then right click on it and select a representation that works with Hex formats (say I32 or U32).
Then right click on it again and select Format and Precision...
Now you should be able to select Hexadecimal format.

Dialog box user input in AWT

Hey,
I need help implementing a dialog box for user input. I looked at the entry for dialog box on SUN website but i dont have a frame or any of the other components required to use the constructor. I am using an Applet.
Thank you in advance.

The first thing I saw on your code, I've not even looked through it yet, was you are using == to compare Strings... this will almost never work, and will definitely not work for how you are using it. Objects, like Strings, have methods for comparing, in the case you want it's myString.equals(otherString);
You have several options on getting the data from your second window, the easiest is probably just to make a public getter. Since your Window #1 has visibility to your second window, you can use the getter freely.
on the Window #1 side:
myPieceOfData = mySecondObjectRef.getMyDataValue();and on the Window #2 side:
public myDataType getMyDataValue(){
return theReauestedData;
}Congratulations on getting going on Java. One thing about college, they usually do not care what language you are using, they are teaching concepts not tools--they usually leave the tool learning up to you.
Best of luck in your classes.

Define speakable command dialog box does not allow keyboard input

According to article http://support.apple.com/kb/PH11447, one is supposed to easily be able to create speakable commands based on keyboard shortcuts:
Open the app that contains the shortcut you want.
Press the listening key (or speak the key, depending on your settings), and then speak the command “Define a keyboard command.”
In the “Define keyboard command” window, use the keyboard shortcut (such as Command-S), and then click OK.
Type the phrase you want to use to name the command, such as “Save document.”
Step 4 doesn't work, because the dialog box won't permit any input or even allopw the cursor to be in the field.
Any ideas on how to fix/work around this?

Apple doesn't routinely monitor the discussions.
Send Apple feedback. They won't answer, but at least will know there is a problem. If enough people send feedback, it may get the problem solved sooner.

Keyboard input to change the default selection in a dialog box.

Hello,
Let say I close a file that I had just edited without saving. I'll then have a dialog box "do you want to save?" with "yes" as default. If I do not want to save my changes, how can I select "no" or "cancel" with the keyboard?
I'm sure this is an easy one for a long time Mac user.
Thanks

As a matter a fact there is. Just hit the first letter of the choice n = no, c=cancel etc. Edit. I tested this in Word for Mac and it worked but other programs don't so the method below is best.
An alternate method is to tab to the choice and hit enter.
Cheers

Labview runs in front of dialog box from third party .exe - cannot simulate keyboard input

Hello,
I need to use an external software to set some parameters of an actuator. When I run this software from Labview (using System Exec.VI) it opens a screen while loading and then a dialog box. I need to select something from this dialog box (I am using a keyboard simulator). But just after the dialog box appears, Labview's window comes in front of it and then all the keyboard commands end up in the Labview's window instead of the external dialog box.
Has anyone ever had a similar problem? I have been looking aroung and I could not find a solution. I cannot use the ALT+TAB or anything like that because dialog boxes do not appear there (something of "modal" and "non-modal" windows).
I came up with a very unreliable solution by chance: If I hit (actually simulate) one key while the loading screen is on and before the dialog box appears, then the dialog box stays upfront. I think it is like telling the Labview "do not come to the front, I want to stay working in this other window". I do not trust this temporary solution at all but maybe it triggers an idea for a solution.
Please see the attached image: After I hit the RUN button, my exe is called and the "loading" screen is displayed on front. Then, the dialog box is left behind the Labview interface.
Any ideas are welcome!!
Thanks,
Laura

Hi Wayne,
I believe it is a good idea to use Portmon, I will give it a try hopefully today.
I have attached the two manuals that can be downloaded from the actuator's webpage (http://www.miraiintertech.com). Then I have attached the manual of the software (I cannot attached the software because they sell it); check on page 24: CTA-1EX, that's the software I am using.
Isn't it weird that there is little info about the dialog box thing? I would have thought that many people had this issue.
Thanks for the help!
Laura
