JTabbedPane display and input help required...

kaizer · February 3rd, 2004, 02:11 AM

Hi Folks,

I have set up a JTabbedPane with a few tabs. I would like each tab to hold a set of questions (using JTextArea or JLabel perhaps?). My question is as follows:

Can anyone list out the code ( or point me to some samples on the web) to present one question inside a tabbed pane? I can then replicate that code to present all my questions.

This second part is a bit more involved:

I now need to set up a textfield that accepts double numbers and nothing else. I need to trap the input number perform a calculation and present the answer in another text area. How do i set it up adjacent to the question 1 and how do i trap the input?

If you could point me to some sample source code that does this i'd be grateful.

Thanks in advance.

Kaizer.

P.S. I'm using Java Swing II edition from o'reilly. It's a bit too involved for me. Any suggestions for any other Swing book (for J2SDK version 1.4.2_03) that is on the lines of MR. Ivor Horton's Beginning Java 2?

Thanks again.

hi!
   you can add different JPanel objects to your JTabbedPane object and these may contains your questions. means each panel may contain a JTextField or JTextArea as your required.

make a JTabbedPane with three tabs and so therefore you make make three JPanel objects for three tabs

for example make one as

   JPanel tabOne = new JPanel();
   //set properties of this panel as border, background and etc and components like JTextField and JTextArea objects

   simmilarly make three panels and add them
