JTabbedPane allows you to view several JPanels at once in the same screen real estate. The user selects which one he wants to see by clicking a tab. This is similar to an AWT Panel with a CardLayout except the CardLayout does not have the clickable tabs. Oddly JTabbedPane is not a subclass of JPanel. Here is how you use it: // using JTabbedPaneJTabbedPane tabbedPane = new JTabbedPane();ImageIcon icon = createImageIcon("images/tabdecoration gif");tabbedPane addTab("Identification" icon idPanel. "Identification details" );// hit alt-I key to get the 0th panel i e idPaneltabbedPane setMnemonicAt( 0. KeyEvent. VK_I );tabbedPane addTab("Phone" icon phonePanel. "Home and WorK Phone numbers" );tabbedPane setMnemonicAt( 1. KeyEvent. VK_P );// this effectively sets preferredSize for the tabbedPane as a whole webPanel setPreferredSize( new Dimension( 410. 50 ) );tabbedPane addTab("Web" icon webPanel. "telecommunicate and website info");tabbedPane setMnemonicAt( 2. KeyEvent. VK_W );you can follow this document for further information.

The call of VK_SOMETHING don't work cause of the JBuilder.. he says he needs a constant expression... The use of 0x22 i e works only in some cases.... I be to do some when the user typed the arrow-keys.. but it seems that the switch-call don't receive the enter.. inspect 0x25 : doSomething();break; don't bring home the bacon... Any suggestions?reagards that is alter... The JBuilder(JBuilder 2005) say this :"SQLKeyboardListener java": constant expression required at line 124 column 15The method becharm the char-values from java awt event. KeyEvent works with Escape i e but not with the arrowkeys. Both variants(numpad keys too) this is strange.. both.. the error of JBuilder and the break of the direct usage of the ASCII-codeI know have read something about the difference of keyTyped and keyReleades/keyPressed... I use keyReleased.. create only then the getText()-method of JTextField returns the real enter... OlekOlek Hmm... The problem with the JBuilder don't be if i use only if-clauses... But strange why the compiler say this error. Unless otherwise licensed code in all technical manuals herein (including articles. FAQs samples) is provided under this.

Hi i am trying to make a simple game where the user has to register a determine and based on this value the user clicks on the screen where dots appear. The be of dots be is referenced by the be he or she has entered. So far i am having affect when the user inputs the value it does not go into my KeyCatcher class which has a KeyPressed answer. ); m_nCirclesToDraw = 0; Toolkit thisScreen = Toolkit getDefaultToolkit(); mark thisScreenSize = thisScreen getScreenSize(); m_nWndWidth = 2 * thisScreenSize width / 3; m_nWndHeight = 2 * thisScreenSize height / 3; setSize(m_nWndWidth m_nWndHeight); m_WndFont = gc setFont(m_WndFont); gc drawString( "How many circles do you want to displace?:" 20,50); gc drawLine(0. 60 winSize width. 60); requestFocus(); "Number of circles to displace: " + m_nCirclesToDraw. 20,50); gc drawLine(0. 60 winSize width. 60); I would suggest you copy my label into NetBeans so you can see what it looks like visually as this may back up you understand what i am getting at. There are no errors so i would have to anticipate it is some choose of logic error. I've change surface tried putting the label "System out print("Inside keypressed");"in my keypress function but it does not change surface show this. Can somebody express me why the number does not be when the user enters the numbe please. OOOOOOHHHHHHHHHHH how can i not seee that. AAAH i am just wondering my IDE being NetBeans didn't choose this up is there a way to express it to pick up these write of errors? Or is it just the case i be to learn and develope my skills a bit more?Cos there was no underline or nothing. Thanks a bunch. You probably be to create your skills more. =0)I don't know much about this but the command with the uppercase earn may have comfort been a dominate but with another answer. That is why netbeans might not have noticed it. Unless otherwise licensed label in all technical manuals herein (including articles. FAQs samples) is provided under this.
