SetMnemonic(int) on JButton not working!
Hi,
I tried the following code on a JButton
JButton eg = new JButton("Cancel");
eg.SetMnemonic(KeyEvent.VK_C);
however nothing get underlined.
I am using 1.4.2_03
Java is using a new "feature" in Windows XP (may also be in Win2K, I'm not sure).
In XP, to get the mnemonics to show all the time, go into Control Panel, then Appearance and Themes, then click the Display label. You are now presented with a Display Properties window. Click the Appearance tab. Now click the Effects button and you'll find a checkbox at the bottom which controls whether mnemonics always show, or only show when you press the Alt key.

Hi,
I am programming a Traffic Light, consisting of 3 lights, and a caption describing who's Traffic Light it is. Traffic Lights are to be used inside a bigger program. But as it is, I'm trying out how to program one Traffic Light.
I created a Light object. A TrafficLight object contains 3 of these objects, and a caption. The TrafficLight object is to be used as a button, so the user can push it, after which some magic has to happen, which I still need to develop. The problem I have is the button does not work.
So, the relevant parts of the code. First the main:
public static void main (String [] args) {
JFrame frame = new JFrame();
frame.setBounds(0, 0, 100, 400);
TrafficLight light = new TrafficLight("Caption", "ERR", true);
frame.add(light);
// frame.pack();
frame.setVisible(true);
}Then the TrafficLight object:
public TrafficLight () {
setUp();
private void setUp() {
JComponent component = createComponent();
add(component);
setVisible (true);
private JComponent createComponent () {
JPanel panel = new JPanel(null);
panel.setBounds (xCoordinate, yCoordinate, WIDTH, HEIGHT);
JButton tlsButton = new JButton();
tlsButton.setBounds(xCoordinate, yCoordinate, WIDTH, HEIGHT);
boolean isOn = true;
boolean isNewProblem = true;
tlsButton.setActionCommand(name);
tlsButton.addActionListener(this);
// Create the lights
redLight = new TlsLight (0, 0, Color.RED, isOn, isNewProblem);
tlsButton.add(redLight);
yellowLight = new TlsLight (0, WIDTH, Color.YELLOW, !isOn, isNewProblem);
tlsButton.add(yellowLight);
greenLight = new TlsLight (0, 2 * WIDTH, Color.GREEN, isOn, !isNewProblem);
tlsButton.add(greenLight);
tlsButton.add(customerLabel, Component.CENTER_ALIGNMENTl);
panel.add(tlsButton);
return panel;
}And, finally, the TlsLight object:
public void paint (Graphics graphics) {
setSize(width, width);
int diameter = width - 2 * insets;
// Paint the background (square) based on if the Customer has a new problem or not
if(isNewProblem) {
background = Color.GRAY;
else {
background = Color.BLACK;
graphics.setColor(background);
graphics.fillRect(xPos, yPos, width, height);
// Set color light based on problemStatus
if(isOn) {
graphics.setColor(theColor);
} else {
graphics.setColor(background);
graphics.fillOval(xPos + insets, yPos + insets, diameter, diameter);
// Set the background of the light
graphics.setColor(Color.WHITE);
// Paint the background
graphics.drawOval(xPos + insets, yPos + insets, diameter, diameter);
}When I push the button, nothing happens. Do you know what I need to do to get my prog working?
TIA,
AbelI don't know what goes on in your ActionListener, but I have a feeling that something is missing there.

Need a little help with a Jbutton not working out the way I planned
The following code is to fulfill an assignment I am working on. The problem I am having is with the btnCalc. For some reason when the button is used, the results I get is from another button. I think the variables are set right for the program to function properly but I am really hung up on this. Do anyone have any suggestions?

}This portion to be exact. All the buttons work for me except this one. I need to calculate user input and also use the fixed data that can be found in the dblTrmLoanRate array. When I choos to use user input instead, the program either crashes or for some reason uses the year7InterestRateBtn instead.
if (command == btnCalc)
//dblLoanAmount = Double.parseDouble(txtTotalMort.getText() ); // Loan amount
//interestRate = Double.parseDouble(txtInterestRate.getText() ); // /100 )/ 12; // Devides rate

//int intYearsMonths = Integer.parseInt(txtYearsInput.getText() );// * 12; //Multiplies loan length
int months = Integer.parseInt(txtYearsInput.getText() )* 12;
I was going to leave out the remed portion but thought it might help you with the navigation. I am sorry I did not use code tags, but I am going to go find out what those are and use them in the future. -
JButton not working with for loop...
I am still very new to Java and am having trouble grasping it. I am trying to put together a program that paints a graphic and then each time the "Press Me" button is pressed, an oval randomly appears giving the impression that the picture is 'disappearing' a little at a time. When I run it now, 20 ovals randomly appear all at once instead of waiting for the button to be pushed. Does anyone have any advice for me on how to modify the code? Here is what I have so far...

I am having a problem with JButtons and JCheckBoxes in java. I am finding myself having to click the JButtons more than once in some situations to get to the next stage of my GUI. With the JCheckBoxes it sometimes takes a couple of clicks to change the state (unticked -> ticked). This seems to be occurring more than often. Can anyone help?
If there are clicking problems, it's coming from the computer you're on, not java. There isn't much you can do about that

MB Air Int. Speakers Not Working
The option for internal speakers went away. Tried everything in these discussions. Only option on output is "headphones". If I do a PRAM reset, or SMC, upon reboot I see the "internal speaker" option, but as soon as I press either the volume button on the keyboard or start some music playing, it goes away and becomes "headphones" again.
This is a new 2013 MB Air. 13". All options.
Thanks in advance.I have this problem too, does it work with headphones?
For me it works with headphones, but not the speakers.
I am running in OS X though, makes me wonder if it is a hardware related problem. -
SetSize(int,int) not working in JTextPane.. Please help

SetMnemonic not working in UNIX
Hello,
I'm tried to set a key mnemonic as follows:
JButton close = new JButton("Close");
close.setMnemonic(KeyEvent.VK_C);
This piece of code works fine in NT but not in UNIX. I tried searching all queries in this forum. I haven't got any inputs ?? Any suggestions ??
Sunil.Hi,
This was the outcome of my research.
I thought of running the app. directly on the Sun server instead of using Exceed emulator (client). I didn't see those warning messages and the mnemonics worked fine.
To answer my question earlier, warning messages are directly related to the issue of mnemonics not working on the client machine.
Still looking into why its not working from any client which uses Exceed.
Thanks,
Sunil. -
GetObject(int, Map) not working with oracle JDBC
I'm using Oracle and I'd like to get Date fields as Timestamps since an Oracle date column includes time. I'm trying to use getObject(int, Map) to map the types to Java objects, but it's not working. This is my code:
public static final HashMap oracleMap = new HashMap();
static{
try{
oracleMap.put( "DATE", Class.forName("java.sql.Timestamp") );
oracleMap.put( "NUMBER", Class.forName("java.math.BigDecimal") );
oracleMap.put( "VARCHAR2", Class.forName("java.lang.String") );
oracleMap.put( "CLOB", Class.forName("java.sql.Clob") );
oracleMap.put( "LONG", Class.forName("java.lang.String") );
}catch(Exception e){
IllegalStateException ise = new IllegalStateException("Oracle type mapping failed.");
ise.initCause(e);
throw ise;
}And
BASE.println("rs.getClass().getName(): "+rs.getClass().getName());
BASE.println("rs.getMetaData().getColumnTypeName(i): "+rs.getMetaData().getColumnTypeName(i));
if(rs.getClass().getName().startsWith("oracle")) valObj = rs.getObject(i, DOMTools.oracleMap);
else valObj = rs.getObject(i);
BASE.println("valObj.getClass().getName(): "+valObj.getClass().getName());Here's a snippet of my output that illustrates the code not working:
rs.getClass().getName(): oracle.jdbc.driver.OracleResultSetImpl
rs.getMetaData().getColumnTypeName(i): DATE
valObj.getClass().getName(): java.sql.Date
Anyone know if this is a driver issue? Anyone had luck doing this with Oracle?
Thanks.Well, I'd like it to be java.sql.Timestamp instead of
java.sql.Date. My actual type is an oracle "DATE".
Are you saying the Map key for this would be
"TIMESTAMP" and that by default it maps to
java.sql.Date? Doesn't seem like that makes sense.I am saying that "TIMESTAMP" is not an oracle value but is instead a JDBC value. Thus it is up to to the driver, not you, to determine what oracle types map to the JDBC type. -
On Vista not working host('cmd /c copy C:\docsys\*.int C:\docsys\hsd.txt');
Dear All Experts,
We r running OAS 10g (10.1.2)
On Windows XP Client below command (Merging .INT files in one file hsd.txt) is working perfectly
host('cmd /c copy C:\docsys\*.int C:\docsys\hsd.txt');
But On Windows Vista Clent it's not working and not giving any error.
Please guide to perform this for Windows Vista Clients.
Thanks

Edited by: Eidy on Jan 23, 2009 1:38 PMI think you may be confusing how Forms applications work. Commands such as HOST and TEXT_IO all execute on the server and not the client. This means that in your case the server (+where Application Server is installed+) must be a Windows platform since you are trying to execute a "Windows" command. Second thing is that because this will execute on the server, the client platform has nothing to do with the problem.
I suspect that previously you tried this code in a Forms Builder environment on WinXP then moved the form (fmb/fmx) to another machine where you then tried accessing it from a Vista client. Run from the Builder using OC4J, the code will work because the server and the client are the same machine. Additionally, when running Application Server additional security issues need to be considered. For example, many command line calls will not execute correctly in AS when the server is any Windows platform because the owner of the frmweb.exe process (OPMN) does not have permission to launch a command windows (cmd).
To permit server side HOST calls to execute correctly on a Windows server, you will need to do the following:
1. In the Windows Services management console, locate the server entry for the Oracle Process Manager for the Middle Tier
2. Open the Properties for this service by double clicking on it.
3. Select the Log on tab
4. Check the box labeled "Allow service to interact with Desktop." Click OK to accept the change.
5. The above change will require restarting OPMN or restarting the machine.
IMPORTANT:
Before making the above change, you should be aware of the impact of doing so. Be sure to refer to the Microsoft documentation which explains the Service options:
http://technet.microsoft.com/en-us/library/cc782435.aspx
Back to the beginning :-)
If you want this type of command to execute on the client, you will need to use a custom Java Bean or WebUtil. Information about WebUtil can be found here:
http://www.oracle.com/technology/products/forms/htdocs/webutil/webutil.htm
Be aware that WebUtil is included in Developer Suite 10.1.2 and should not be downloaded from OTN as the version in 10.1.2 is newer. For Application Server 10.1.2, you will need to copy the appropriate WebUtil files from Developer Suite to your AS environment and configure it. Refer to the documentation and Release Notes all available on the page noted above. -

JTextField.select(int, int) not working in modal JDialog
Hi
I have discovered something peculiar. When I have a JDialog, and it is modal, then the select method of any JTextfield will surely fail. (Only tested on win32)
What the owner is does not matter (even null will give the same result). I made a JFrame for your convenience.
import javax.swing.*;
public class MyDialog extends JDialog
private JTextField tf = new JTextField("not selected >selected< not selected");
public static void main(String[] args)
JFrame f = new JFrame("Some parent frame");
f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
f.setVisible(true);
new MyDialog(f);
public MyDialog(JFrame parent)
super(parent, "Child dialog", /*Selecct modality*/ true);
// super();
super.setDefaultCloseOperation(WindowConstants.DISPOSE_ON_CLOSE);
super.add(this.tf);
super.pack();
super.setLocation(0, 50);
super.setVisible(true);
// Selection does not work when dialog is modal.
this.tf.select(14, 22);
this.tf.requestFocus();
}I did not find a bug in the database concerning this.
Did I do something wrong, or should I post this as a bug?1) Please do not dredge posts that are months or years old. If you have something important to say, create your own thread.
2) If you have the same problem, then use the same solution.
3) If this doesn't work, then show your problem: show your code. We don't want to see all of it, but rather you should condense your code into the smallest bit that still compiles, has no extra code that's not relevant to your problem, but still demonstrates your problem, in other words, an SSCCE (Short, Self Contained, Correct (Compilable), Example). For more info on SSCCEs please look here:
http://homepage1.nifty.com/algafield/sscce.html
Also, when posting your code, please use code tags so that your code will be well-formatted and readable. To do this, either use the "code" button at the top of the forum Message editor or place the tag [code] at the top of your block of code and the tag [/code] at the bottom, like so:

Megacom not working for both LD and Int'l
I got the same issue described here https://supportforums.cisco.com/message/311063#311063 but only differences are my setup is using CCM 4.2 and Cisco 3845's.
To make a LD call to work, I got to set the "Called party IE number type" under the GW config to National; and
To make an Int'l call to work, I got to set this value to International.
If I leave everything default, i.e. Cisco CallManager, only LD works.
Basically, I couldn't make both LD and Int'l to work. It's either one way or the other.
Any workaround to make both to work would be greatly appreciated.
Thanks,

Swing components in applet not working in web browser
Hi Guys,
I've created an applet which makes use of some swing components, but unfortunately, not all of them function properly in my web browser (internet explorer or Mozilla Firefox). Its mainly the buttons; the last buttons works and displays the correct file within the broswer, but the first 5 buttons do not work...
any help please on how I can sort this problem out?
Heres the code for my applet:
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import java.applet.*;
public class MainAppWindow extends JApplet
int gapBetweenButtons = 5;
final JPanel displayPanel = new JPanel(new BorderLayout());
public void init()
//Panel for overall display in applet window.
JPanel mainPanel = new JPanel(new BorderLayout());
mainPanel.add(new JLabel(new ImageIcon(getClass().getResource("images/smalllogo2.gif"))),BorderLayout.NORTH);
//sub mainPanel which holds all mainPanels together.
JPanel holdingPanel = new JPanel(new BorderLayout());
//Panel for displaying all slide show and applications in.
displayPanel.setBackground(Color.white);
displayPanel.add(new JLabel(new ImageIcon(getClass().getResource("images/IntroPage.jpg"))),BorderLayout.CENTER);
displayPanel.setPreferredSize(new Dimension(590,400));
JPanel buttonPanel = new JPanel(new GridLayout(6,1,0,gapBetweenButtons));
buttonPanel.setBackground(Color.white);
JButton button1 = new JButton("User guide");
button1.addActionListener(
new ActionListener() {
public void actionPerformed(ActionEvent e)
if(displayPanel.getComponents().length > 0)displayPanel.removeAll(); // If there are any components in the mainPanel, remove them and then add label
displayPanel.setBackground(Color.white);
displayPanel.add(new JLabel(new ImageIcon("images/UserGuide.jpg")));
displayPanel.revalidate(); // Validates displayPanel to allow changes to occur onto it, allowing to add different number images/applicaions to it.
JButton button2 = new JButton("What is a Stack?");
button2.addActionListener(
new ActionListener() {
public void actionPerformed(ActionEvent e)
if(displayPanel.getComponents().length > 0)displayPanel.removeAll();
displayPanel.setBackground(Color.white);
displayPanel.add(new JLabel(new ImageIcon("images/WhatIsAStack.jpg")));
displayPanel.revalidate();
JButton button3 = new JButton("STACK(ADT)");
button3.addActionListener(
new ActionListener() {
public void actionPerformed(ActionEvent e)
if(displayPanel.getComponents().length > 0)displayPanel.removeAll();
displayPanel.setBackground(Color.white);
displayPanel.add(new JLabel(new ImageIcon("images/StackADT.jpg")));
displayPanel.revalidate();
JButton button4 = new JButton("Stacks in the Real World");
button4.addActionListener(
new ActionListener() {
public void actionPerformed(ActionEvent e)
if(displayPanel.getComponents().length > 0)displayPanel.removeAll();
displayPanel.setBackground(Color.white);
displayPanel.add(new JLabel(new ImageIcon("images/StacksInTheRealWorld.jpg")));
displayPanel.revalidate();
JButton button5 = new JButton("DEMONSTRATION");
button5.addActionListener(

Demonstration app = new Demonstration();
JPanel appPanel = app.createComponents();//gets the created components from Demonstration application.
appPanel.setBackground(Color.pink);
displayPanel.add(appPanel);
displayPanel.revalidate();
JButton button6 = new JButton("Towers Of Hanoi");
button6.addActionListener(
new ActionListener() {
public void actionPerformed(ActionEvent e)
if(displayPanel.getComponents().length > 0)displayPanel.removeAll();
TowerOfHanoi app = new TowerOfHanoi();
JPanel appPanel = app.createComponents();//gets the created components from Towers of Hanoi
JPanel mainPanel = new JPanel();//panel used to centralise the application in center
mainPanel.add(appPanel);
mainPanel.setBackground(Color.pink); //sets mainPanel's background color for 'Towers Of Hanoi'
displayPanel.add(mainPanel);
displayPanel.revalidate();
//adding buttons to the buttonPanel.
buttonPanel.add(button1);
buttonPanel.add(button2);
buttonPanel.add(button3);
buttonPanel.add(button4);
buttonPanel.add(button5);
buttonPanel.add(button6);
JPanel p = new JPanel(); // Used so that the buttons maintain their default shape
p.setBackground(Color.white);
p.add(buttonPanel);
holdingPanel.add(p,BorderLayout.WEST);
holdingPanel.add(displayPanel,BorderLayout.CENTER);
//Positioning of holdingPanel in mainPanel.
mainPanel.add(holdingPanel,BorderLayout.CENTER);
//indent mainPanel so that its not touching the applet window frame.
mainPanel.setBorder(BorderFactory.createEmptyBorder(10,20,10,20));
mainPanel.setBackground(Color.white);
mainPanel.setPreferredSize(new Dimension(850,600)); //size of applet window
mainPanel.setOpaque(false); // Needed for Applet
this.setContentPane(mainPanel);
}Thanks for the response. I don't quite understand what you're talking about though. I have, in my humble knowledge, done nothing with packages. I have put the applet class (WiaRekenToolActiz.class is the applet class) in the jar file wia_actiz_archive.jar. From what I read on the tutorial, java looks for the applet class in all the jar files specified. Since I put my CODEBASE as the main url, I thought it baiscally didn't matter where you out the html file.
I shall include the complete html page complete with applet tag to perhaps illuminate a bit more what I mean...
