SetColor not working
In an Applet, in the paint(), the color never changes and the default color (black) is always set. Why this is not working?
String[] colores = ("blue", "cyan", "green", "magenta", "orange", "pink", "red", "yellow", "black", "lightGray", "darkGray", "gray" };
h=0;
for(i=1; i<=numero_personas; i++){
if(str1.compareTo(str2[i]) == 0){
h++;
g.setColor(Color.getColor(colores[h]));
else
g.setColor(Color.getColor(colores[h]));
g.draw3DRect(21,21, 100 ,5,true);
g.fill3DRect(21,21, 100 ,5,true);
I think I'm not using getColor correctly. I dont want to use [Color.blue | Color.red | ...]. In order to change the color depending on the string comparison, What do I need to do?
Thanks
Ahem, yes, except for the fact that the "colores"
thing is not a member of the Colors class, hence the
error on the line that includes:I'm to tired...Sorry...
getColor public static Color getColor(String nm)Finds a color in the
system properties.
The argument is treated as the name of a system property to be
obtained. The string value of this property is then interpreted as an integer which is then converted to a Color object.
If the specified property is not found or could not be parsed as an integer then null is returned
Since I've noticed you're Spanish, from Valencia I suppose, isn't this method searching the colors in english in a spanish OS?? This way it wount find anything I suppose...Not sure about this, but try in the
colores array to writte them in spanish....
Hope it helps,
ANeto

Hi ,
I have done some color change on a table column based on certain condition. which is working fine in 11i instance but when i have migrated the same in R12 it is not working.
Code in (PR) :
OALinkBean bean1 = (OALinkBean)webBean.findChildRecursive("Addi1");
if (thsholdVal<CalThVAl)
{ row.setcolor("1");
OADataBoundValueViewObject cssjob1 = new OADataBoundValueViewObject(bean1,"color");
bean1.setAttributeValue(oracle.cabo.ui.UIConstants.STYLE_CLASS_ATTR, cssjob1);
else
row.setcolor("2");
OADataBoundValueViewObject cssjob1 = new OADataBoundValueViewObject(bean1,"color");
bean1.setAttributeValue(oracle.cabo.ui.UIConstants.STYLE_CLASS_ATTR, cssjob1);
Custom.xss code: (Location $OA_HTML/cabo/styles)
<style selector=".2">
<includeStyle name="DefaultFontFamily"/>
<property name="background-color">#00FF00</property>
</style>
<style selector=".1">
<includeStyle name="DefaultFontFamily"/>
<property name="background-color">#FF0000</property>
</style>
Please give me a response if i missed any thing or i need to make some R12 specific change.I don't think there is a specific change required for R12. Have you bounced the Apache after replacing the custom.xss file?
Thanks

'NAVIGATE_ABSOLUTE' method is not working in UWL
We are working on Portal 7.0.
Recently We have upgraded from SP 13-0 To 13-5.
After this upgradation We are facing some problems, following is the scenario:
1. We have a ABAP Web DynPro Application say 'A', which has button "View Details".
2. On Clicking of "View_Details" We navigate to other ABAP Web DynPro Application say 'B' .
This was done using the 'NAVIGATE_ABSOLUTE' method of the 'IF_WD_PORTAL_INTEGRATION'.
3. Now The Same Application 'A' is being send as the Workitem to Approver's inbox.
4. Approver also was able to click on 'View_Details' button and Application 'B' used to call using 'NAVIGATE_ABSOLUTE'.
5. After upgradation, Point 2 is working fine. but point 4 is not working i.e. 'NAVIGATE_ABSOLUTE' functionality is not working when the application is send as workitem.
Please guide us for the above problem. Points assured for best solution.Hi
Thanks for your reply. Actually i wrote simple applets and those are working well.
So i did debug the code and i found that when i am running the following code in Apple MAC IE, nothing is happening in handleEvent method. Especially it is not going into the if statement (if (evt.id==401)). here i am checking for KEY_PRESS. I also tried with keyDown method but same problem in MAC IE.
I am pasting the code that is giving me problem.

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.
public TrafficLight () {
setUp();
private void setUp() {
JComponent component = createComponent();
add(component);
setVisible (true);

tlsButton.setActionCommand(name);
//tlsButton.addActionListener(this);
tlsButton.addActionListener(new ActionListener(){
public void actionPerformed(ActionEvent evt){
System.out.println("Hello World!"); //Implement with you own stuff....
// 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);

KeyListener not working in Linux
Hello guys, I'm having a weird problem I was hoping I could get resolved.
I finished a Pong applet for my Java class, and it works just fine under Windows and on my Mac.
But when I run it under Linux, the Applet doesn't work correctly.
The applet draws, and my timer works, but my KeyListener does not work.
I believe all of my Java files are updated properly.
But I do not understand why KeyListener does not work under Linux, but it does in Windows.
I then made a very basic applet just to test my KeyListener, and it still does not work.
This is how I was taught to do KeyListeners, but if I'm doing something wrong, please help me out!
here is the basic program code:
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class Test extends JApplet implements KeyListener
int x = 0;
int y = 250;
public void init()
addKeyListener(this);
public void paint(Graphics g)
g.setColor(Color.white);
g.fillRect(0,0,500,500);
g.setColor(Color.black);
g.fillRect(x,y,50,50);
public void keyPressed(KeyEvent event)
int keyCode = event.getKeyCode();
if(keyCode == KeyEvent.VK_RIGHT)
x += 10;
public void keyReleased(KeyEvent event)
public void keyTyped(KeyEvent event)What if don't use a KeyListener but instead use key binding? For instance,
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;

This is my 'paddle' game. You bounce a ball around the around the screen, and it's all working. I'm on the final part, which is what happens when you miss the ball (it goes off the left side of the screen). I'd like to print out a message to the middle of my screen saying "Press R to Reset", while the ball is not anywhere to be seen on the screen (is there a way I can get it to stop moving? my method right now is just to place it far away off screen, which just doesn't seem very professional to me). I made an if statement that should control this, but it's not working (when the you miss the ball, it disappears but nothing prints to the screen, and pressing R doesn't do anything either ) .
To skip quickly to the if statement just use the find option in your browser and put in 'PROBLEM'
This is all written in an applet.
This is my code:
int width, height, x, ypaddle, xball = 1, yball = 1, xctrl = 1, yctrl = 1, speed = 5, scorekeeper = 0, startkeeper = 0, keykeeper;

Code not working, anyone know why?
I'm making a simple pong game, and it's important to me that I use JAVA as efficient as possible (that is, use object orientated stuff, mostly). So, for drawing the ball and the players, I had thought up the following steps:
- the applet has an array list that contains drawables*
- if the ball and players need to be drawn, the applet uses a for-each loop, wich will call the draw(Graphics g) of all the drawables in the array list.
* interface, guarantees that the method public void draw(Graphics g) is pressent.
This is how I programmed it:
http://willhostforfood.com/access.php?fileid=32821
Only problem is, it doesn't work. The method paint() of the applet should result in "Hello World" being drawn on the screen (I know this seems like an eleborate method, but using seperate objects will help organise things once I have like, 20 - 30 balls on screen), but it doesn't.
Does anyone know why it is not working?Here ya go, this is something I did quite a while ago, knock yourself out:

Repaint() method is not working in MAC IE
Hi All
why repaint method is not working in MAC IE ? What i am doing is in one class which is inheriting Canvas class getting the keybord input then adding it to main applet.
Please help me i am trying it for whole week and i couldn't find any solution. I didn't put my code but if anyone is willing to help me i can post it.
Thanks in advancs
ShanHi
Thanks for your reply. Actually i wrote simple applets and those are working well.
So i did debug the code and i found that when i am running the following code in Apple MAC IE, nothing is happening in handleEvent method. Especially it is not going into the if statement (if (evt.id==401)). here i am checking for KEY_PRESS. I also tried with keyDown method but same problem in MAC IE.
I am pasting the code that is giving me problem.
import java.awt.*;
import java.applet.*;
public class testApplet extends Applet
public void init()
setLayout(new BorderLayout());
editableArea = new EditableArea();
editableArea.setBackground(Color.yellow);
add("Center", editableArea);
EditableArea editableArea;
import java.awt.*;
public class EditableArea extends Canvas
String s = "";
public boolean handleEvent(Event evt)
if (evt.id==401)
if(evt.key >= 32 && evt.key <= 255)
char c = (char)evt.key;
s = s + c;
repaint();
return super.handleEvent(evt);
public void paint( Graphics g )
g.setColor(Color.blue);
g.drawString( s,5,15);
-------------------------------------------------------------------- -
Why the drawLine() is working only inside the paint method??
BufferedImage image = new BufferedImage(800,500,BufferedImage.TYPE_INT_ARGB);
Graphics2D g = (Graphics2D)image.getGraphics();
public void paint(Graphics g)
g.setColor(Color.black);
//Here, the drawLine() method works
g.drawLine(50,0,50,150);
public void paintX(Graphics g,Point c)
//Here, the drawLine() method does not work
g.setColor(Color.black);
g.drawLine(0-e,0-e,50-e,50-e);
g.drawLine(0-e,50-e,50-e,0-e);
repaint();
}er, unless you're using JDK 1.5 and it introduces methods I know nothing about, as far as I know
public void paintX(..) is not a AWT or Swing method. Thus it will never be invoked unless you call it. -
Why handleEvent is not working in AppleMac IE ?!
Hi There
I am trying to write an editor which should work in Apple MAC and Windows !!.I wrote the following classes and working fine in Windows IE/Netscape and MAC Netscape, But not working in MAC IE. Someone please point out me where i am making mistake. I used JDK1.0.2 version to combile the classes.
import java.awt.*;
import java.applet.*;
public class testApplet extends Applet
public void init()
setLayout(new BorderLayout());
editableArea = new EditableArea();
editableArea.setBackground(Color.yellow);
add("Center", editableArea);
EditableArea editableArea;
import java.awt.*;
public class EditableArea extends Canvas
String s = "";
public boolean handleEvent(Event evt)
if (evt.id==401)
if(evt.key >= 32 && evt.key <= 255)
char c = (char)evt.key;
s = s + c;
repaint();
return super.handleEvent(evt);
public void paint( Graphics g )
g.setColor(Color.blue);
g.drawString( s,5,15);
--------------------------------------------------------------------Someone please give me some idea, i am struggling for long time. As our customers are printers they need the MAC IE. Any help will be appreciated.
