I want to create an internal wizard in my Java GUI application such that the clicking of a menu item results in popping up of a wizard that guides the user through a series of steps. I have done lot of research and couldn't find anything with decent enough documentation. Can someone help me out please? Has someone worked on creating a wizard that pops up INSIDE a GUI application?
Thanks in advance!
You can use cjwizard. It can be embedded inside a JDialog as it is based in JPanel.
And you can see how to use it in https://github.com/cjwizard/cjwizard/blob/master/docs/quickstart.md for example:
// create the WizardContainer:
final PageFactory pageFactory = /* create a PageFactory, see the link */;
final WizardContainer wizard = new WizardContainer(pageFactory)
// stick the WizardContainer into a dialog:
final JDialog dialog = new JDialog();
dialog.getContentPane().add(wizard);
dialog.pack();
dialog.setDefaultCloseOperation(JDialog.DISPOSE_ON_CLOSE);
dialog.setVisible(true);
Disclaimer: I'm part of the development team.
If there are no third-party libraries to satisfy the requirements you have then you can just write your own approach. A set of panels, each one having Previous, Next buttons and some of them Finish. The current panel just needs to know which are the previous and the next panels.

I'm starting using java with NetBeans IDE. I'm using drag and dop GUI, it's so easy to use, but I got a problem. I'm writing this code at the contructor:
JComboBox combobox=new JComboBox();
combobox.addItem("Apple");
combobox.addItem("Banana");
for(int i=1;i<=10;i++){
combobox.addItem(i);
}
just right above initComponents(); hoping that my new combobox will shown when I run the project, but it doesn't. Did I do something wrong? Thanks in advance
Yes, you are creating a JComboBox, and yes, you are adding items to it (numeric and int -- that's a problem, but that's a discussion for another day), but no, you're not showing any code where you add this newly created JComboBox to a component that is displayed in the GUI. To display a component in a Swing GUI, it must be created and added to a component that is ultimately displayed in a top-level window, in the "GUI".
So this begs the question, how do you add your created JComboBox to your GUI that you've created with drag and drop code? One way: you could add it to say a JPanel that's already in your GUI, but you will need to do this after initializing components, usually this means after the constructor calls initComponents(), and you'll also need to make sure that this JPanel uses a layout manager that makes it easy for it to accept new components (this means most of the layout managers except NetBean's default layout, GroupLayout).
There are other issues, such as whether or not the container holding your JComboBox is large enough to display it, but the best suggestion that I can give is for you to go through the Swing tutorials, and hit especially hard the layout manager section. You can find links to the Swing tutorials and other Swing resources here: Swing Info.
I am new to Java GUI I deigned and window and menu item using java design tool.But when I want to create window for menu item say New contact I did not find an option to do that in event handler so I did it manually by coding it.But when I go to design part and click on New Contact it does not show the window I created via code.
Here is the screen shot of deign view -when I click on New Contact nothing happens.
Now in the source code when I run it I get the window I coded
Is there any possible way I can make it work in design part? I did not find any option to do it in Add Event Handler
You do not want a JFrame to show another JFrame -- that's a bad GUI design since it means that your application is actually two applications. Better to show a dialog window such as a JDialog. Please see The Use of Multiple JFrames, Good/Bad Practice?
If you want to design a 2nd window, create a new Java program in NetBeans, one that creates this second window (again, better for it to be a JDialog, not a JPanel)
Give it a constructor that allows passing in the parent window, and then pass that to the JDialog super constructor
And then in your ActionListener code above, create a new object of this new program, passing in the current JFrame.
In the future, please post code as code-formatted text, not as an image, since this way we can copy, paste, compile and run it if we want, allowing us to better understand your code and your problem.
I am trying to learn how to use java swing components. I have been trying to build up something like a pop up window.Like facebook when we select a friend a window pops up.I have a list of friends. I wish to create a pop up window when the user selects one of his friend from his friend list.But the problem is , each time I run this code, two internal frames are popping up.I fail to sort out the problem.Here is the code snippet.
Thanks in advance.
private void list2ValueChanged(javax.swing.event.ListSelectionEvent evt) {
JInternalFrame f = new JInternalFrame((String)list2.getSelectedValue(),
false,true,false,true);
f.setSize(150,150);
f.setVisible(true);
desk.add(f,BorderLayout.SOUTH);
}
Here desk is the variable name for JDesktopPane.
A ListSelectionListener will generate multiple events every time the selection changes.
You need to check the ListSelectionEvent.getValueIsAdjusting() to make sure the selection is finished adjusting
if (!event.getValueIsAdjusting())
// create your internal frame.
I am developing an application which needs to pop up new JFrame B with different components, when I click on a button on JFrame A. How do I achieve that?
I don't want to use the tabs.
Use a JDialog , problem solved!
See this java tutorial for more help : How to Make Dialogs
I'm not sure why no one has suggested CardLayout yet, but this is likely your best solution. The Swing tutorials have a good section on this: How to use CardLayout
In a nutshell (a simple solution), you register a listener with the JButton and then have the listener perform the tasks you want it to perform:
setVisible(true) for one frame.
setVisible(false) for the other one.
Regards!
One way to approach this would be to create another jFrame and then add a listener onto your button like so:
jFrameNew.setVisible(true);
This way you have a whole new frame to work with. If you want to just have a pop-up message you can also try using the jDialog frames.
Depending on which IDE you are using...for example Netbeans has a gui that makes designing interfaces slightly easier, so you can test out the different frames.
i've made a menu bar with netbeans.
in the menubar i've got
file >exit
Help >Help F1
>about
the problem is i don't know how to link up either help or about to another frame that has everything i want the user to see.
can someone please tell me how to go to a new frame once eiher help or about is clicked?
thanks
For About, you would typically use a modal dialog, i.e. a JOptionPane - using those is pretty straightforward. For Help, you don't want a modal dialog, but a new separate JFrame. But you don't have to "go to" it - just create it and call show() - that's all you need to do. Like modern GUIs in general, Swing does not have an explicit control flow through or between masks. The GUI is shown, and only when the user interacts with it is your code in the various event handlers called.
