Cardlayout GUI

I

IanH

Hi,

I am currently working on a Payroll Interface. I have been
experimenting with a cardayout view. First, I want to allow employees
to enter their first and last name and to pick how their remuneration
is calculated ie, salary, hourly, commission etc.

At the moment I just have a combo-box that allows each employee to pick
their remuneration type and based on this selection a card is called.

My question is - is it possible to display a Jtextfield for the first
and last name on the interface with the combo-box, and if so how would
i go about it.

any help would be appreciated.

Ian

A very good place to start to learn how to use the different layout managers
is the Java Tutorial. You can find it here:
http://java.sun.com/docs/books/tutorial/index.html. You want the chapter
(they call them "trails") named "Creating a GUI with JFC/Swing". If you
click on that chapter, you'll see a section of the chapter entitled "Laying
Out Components Within A Container"; click on that. I suggest that you then
click on "A Visual Guide To Layout Managers" to get an overview of the
different standard layout managers; you may find one that is more
appropriate than CardLayout for your requirements. In any case, choose the
one that seems best and then click on the 'How to' article for that Layout
Manager for a proper description of how to use each one.

In answer to your specific question, yes, you can certainly have one or more
text fields on the same card as a combo box. The specifics of how to create
text fields can be found by going to this page:
http://java.sun.com/docs/books/tutorial/uiswing/components/components.html
and then clicking on the "text field" link (I doubt that you want a
formatted text field for this problem.) That will show you how to create the
text fields; there is a link to an article on creating combo boxes on that
page too. Once you've created the components though, you will need to figure
out how to lay them out; they usually won't become visible unless they have
been layed out correctly. That's where the layout manager pages are going to
come in handy :)

Basically, I think you have the right design in mind: you want the first
card to prompt for the name and the pay type; then, based on the value
chosen from the combo box, you go to another card that prompts for the
remaining pay information that is necessary for that pay type. Now, if you
really want to start to look professional, you can do some edits on the
information the user gives to show that you won't accept just any old data
but that probably won't be expected in a school assignment. Then, you'd
likely save the information somewhere; in a professional application, it
would likely be to a database. Again, though, a school project probably
won't expect you to go that far.

This should get you started. Ask followup questions if you start getting
stuck in the details and someone will probably be along to help you.

Hi,

I have been working on the above problem. I have tried to insert a
JLabel and a JtextField by following examples on the net and in books
but to no such luck. I have inserted the correct code(i think) to
include these components however, my code is running with no errors nor
does it display the components. If anyone has any suggestions on where
I'm going wrong I would be glad to hear them.

What components do not display.. Or which JLabel and JTextField? Looks
like all display for me. I'm running JDK 1.6.0

Label1 and TextField1 are not displaying on the GUI.(Hope I am
explaining it properly) I'm fairly new to Java. I'm running JDK 1.5.

Well you define textFieldPane and add textField1. Then define labelPane
and add and add textField1 to that panel. The only problem is you do not
add textFieldPane or textField1 to pane.

Thanks for that. I have made the following changes put i seem to be
getting an error. Is it ok to add the JTextField by doing the
following?

JTextField textField1 = new JTextField();
JTextField.add(textField1);

JLabel label1 = new JLabel();

label1.setText("Enter name");
labelPane.add(label1);


JTextField textField1 = new JTextField();
JTextField.add(textField1);



String comboBoxItems[] = { HOURLYPANEL, COMMISSIONPANEL,
BASEPLUSPANEL, SALARYPANEL };
JComboBox cb = new JComboBox(comboBoxItems);

No. You can't add a text field to itself; you have to add it to a container,
like a JPanel. You'll need something like this:

JPanel myPanel = new JPanel();
JTextField myTextField = new JTextField();
myPanel.add(myTextField);

Ok, the textfield is still not appearing on the GUI. I have also added
the following code. Is this what i use to display the textField on the
GUI?
Ian

pane.add(myPanel, BorderLayout.PAGE_START);
pane.add(cards, BorderLayout.CENTER);

Could you post the complete current version of the program, just to make
sure that we are looking at the same code?

Also, did you look at the Java Tutorial sections on creating the different
components and using the layout managers? If not, you may find your
questions answered there. Two other points:
- GUI components are typically (but not always) added to the ContentPane of
your application with the getContentPane() method in the constructor for
your JFrame
- the GUI itself won't normally be visible until you do a setVisible() on
the JFrame

This tiny fragment illustrates both points:

================================================================

public class PayrollApplication extends JFrame {

public static void main(String[] args) {

PayrollApplication myApplication = new PayrollApplication(); //creates
GUI
myApplication.pack(); //packs GUI
myApplication.setVisible(true); //makes GUI visible
}

public PayrollApplication() {

JPanel myPanel = new JPanel(); //creates panel
JTextField nameField = new JTextField(); //creates text field
myPanel.add(nameField); //adds text field to panel

getContentPane().add(myPanel); //adds panel to ContentPane
}

}

================================================================

Naturally, your GUI is more complicated than this one so you'll need to
create more components. But your program will normally follow this model.
