Where is the paint method?

The book I have says it's in the JApplet class, but I can't find it there. Thx

Whoops sorry, already found it in the Java.awt.Container class.

Over-riding the paint() method

I want to create a custom button-rounded sides with straight top and bottom to be exact. I understand that you can use the Component class to create components, and over-ride the paint() method to create the actual button's appearance, but how do you do this? Also how do you go about creating an actionlistener for a component like my button idea? Any help will be appreciated!

Since you are creating your own JButton you want to implement MouseListener so that you can detect the mouse up and mouse down events. If you are going to have a hover image then you want to implement MouseMotionListener as well. Here is an example:
public class MyButton extends JComponent implement MouseListener, MouseMotionListener {
private Vector listeners = new Vector();
public MyButton() {
    addMouseListener(this);
    addMouseMotionListener(this);
public void addActionListener(ActionListener al) {
    listeners.add(al);
public void removeActionListener(ActionListener al) {
    listeners.remove(al);
//add the overridden methods from MouseListener, MouseMotionListener
public void paint(Graphics g) {
    //paint based on the events
}This class will be notified when the mouse enters, exits, is clicked, etc. and you can set a state variable so that your paint routine knows what image to paint.
Hopefully this will clear it up. Not sure how I can make it clearer.

Press and hold down on the Gradient Tool (just below the Eraser Tool) and it will pop up for you to select.
You can also use G as the shortcut key and Shift + G to switch to it.

Where's the "Paint Bucket"?

I just recently uploaded the free 30 day trial of Photoshop CS5 Extended. I currently have Photoshop 7, but what I want to know is... where is the "Paint Bucket"?

Most of the tools on the Tools panel have multiple choices. This keeps the panel small while making a large number of tools available to you. Click and hold on any one of the panel boxes to see all your choices.
The Paint Bucket Tool is here:

Where is the "printf" method?

I have attended to a Sun TechDays lecture showing some new features of J2SDK 1.5 - one of the "hottest things" (hot for the guys with C background...) was the good old "printf" function.
I have downloaded the alpha b31 release. Where is the "printf" function? Is it scheduled to be released in Tiger?
I particularly do not like the "printf" and "scanf" functions, but "promise is debt" (literal translation from the Portuguese).
It is not difficult to write a printf method using the new variance syntax. But the scanf method poses some problems:
char *s = "1000 1.2";
int d; float f;
sscanf (s, "%d %f", &d, &f);
String s = "1000 1.2";
StringReader sr = ...;
___ d = new ___;
___ f = new ___;
sr.scanf ("%d %f", d, f);I can't pass a "Integer" or a "Float" object because they are immutable. If I use the idiom "if you want to pass a int by reference, create a one-element array, pass the array, and get the first element" it will eternize the idiom:
int[] d = new int[1];
float[] f = new float[1];
sr.scanf ("%d %f", d, f);Maybe scanf could return an Object[]. We will have
Object[] o = sr.scanf ("%d %f");
System.out.println (o[0]); //-- the first value
System.out.println (o[1]); //-- the second valueUgly. If Java had tuples:
<d, f> = sr.scanf ("%d %f");
The "principle of minimum astonishment" rules against tuples, although they could be very useful (think the lots of JavaBeans that are created only to return two or three fields...)

What about:
Object[] array = new Object[2];
sr.scanf ("%d %f", array);
Integer i = (Integer) array[0];
Float f = (Float) array[0];

Where is the Stop method for CWDI?

All the other DMA classes have a Stop mehtod. Why not CWDI?

Hi rcsj1,
The Reset method should be used to stop the digital input. A command to stop but not reset the resources was not explicitly exported to be used with the ActiveX control CWDI. Hope that helps. Have a good day.

Where's the clone() method implementation?

this was all i could get from src.jar..
protected native Object clone() throws CloneNotSupportedException;
where is the implementation?
thank you

So the implementation is in some library. And you have already seen the (Java) source. The native code is probably written in C or C++; I don't see any source like that in my Windows SDK so you probably don't have it in yours either.

Where is the "set" method for this ELEMENT?

Hi
I'm trying to understand the relationship between the DTD and XJS, and the JAXB generated code.
Consider the example DTD, XJS, and generated source code (i.e., "value07.java") for ELEMENT value07, below ...
QUESTION#1: Why is there no "set" method generated for ELEMENT "value07a" within the generated value07.java ???
QUESTION#2: How to I code the DTD/XJS in order to force the generation of a "set" method in value07.java???.
-- I want to be able to set a new value for ELEMENT "value07a" in order to generate an XML document containing the new value!!
(NOTE: the reason that ELEMENT value07 (as well as other ELEMENTs) has only a single subelement, is in order to satisfy the XSLT definition in a preexisting application.)

Where is the onAck() method in the ABAP proxy framework?

When working with client proxies there is the possibility of requesting acknowledgements from the receiving party. This will result in a acknowledgement message being sent back after successful delivery (technical acknowledgement) or successful processing of the message.
Java proxies support a callback mechanism by providing an interface com.sap.aii.proxy.xiruntime.ack.AckListenerLocal containing the method.
onAck(com.sap.aii.proxy.xiruntime.ack.AckMessage ack)
An implementation of this interface can be registered to handle the acknowledgment for a specific proxy.
How does this work for ABAP? Is there an ABAP OO interface? Is there a way of registering some handler for acknowledgements by any means?
Thanks for any response on this!

That is bitter truth to hear. I do not understand that because it sounds simple and obvious to provide. Thanks anyway Stefan.
If anybody has a good idea how to setup a trigger that will run upon the receipt of an acknowledgement (not with polling) it would be highly appreciated.

Where is the SOAP Method in XI generated WSDL?

Hi Experts,
I have generated a WSDL from XI for the outbound interface. The web application developer is using this WSDL to send a SOAP request from the web application, but he is not finding a SOAPMethod in the WSDL. Could someone please tell how the XI generated WSDL is to be used from a web application?
Thanks,
Shobhit

Thanks Prateek, but could you send me some document / link on how to send a SOAP request to an XI generated webservice. Is it in any ways different to a regular webservice deployed on a http server.
We are trying to send a SOAP request using a .Net based application. Any clues / leads on how to send the request using the XI generated WSDL.
Appreciate your help.
Thanks,

Stuck with the paint and repaint methods

I am supposed to create a JApplet with a button and a background color. When the button is clicked the first time a word is supposed to appear (I got that part), when the button is clicked the second time the word is supposed to appear again in a different color and in a different location on the Applet (I got that part).
The problem is that the first name is supposed to disappear when the second word appears. So I know I have to repaint the screen when the button is clicked the second time and draw the first string in the same color as the background color to make it invisible.
My problem is I am not sure how I can code to apply different settings each time the button is clicked. Can anyone help? Please let me know if my explanation sucks. I will try to explain better. However here is the code I have so far. I added a counter for the button just for testing purposes.
I just need some hints on what to do and if there is a easier way than using that if statement please let me know. I probably make it harder than it is.
Thanks in advance and Merry Christmas.
import javax.swing.*;
   import java.awt.*;
   import java.awt.event.*;
    public class DisplayMyName extends JApplet
    implements ActionListener
      String myName = "DOG";
      String myName1 = "DOG";
      JButton moveButton = new JButton("Move It");
      Font smallFont = new Font("Arial", Font.BOLD, 12);
      Font largeFont = new Font("Lucida Sans", Font.ITALIC, 20);
      int numClicks = 0;
      JLabel label = new JLabel("Number of button clicks:" + numClicks);
       public void init()
         Container con = getContentPane();
         con.setBackground(Color.RED);
         con.setLayout( new FlowLayout() );
         con.add(moveButton);
         con.add(label);
         moveButton.addActionListener(this);
       public void paint(Graphics g)
         numClicks++;
         label.setText("Number of button clicks: " + numClicks);
         if (numClicks == 2)
         { g.setFont(smallFont);
            g.setColor(Color.BLUE);
            g.drawString(myName, 50, 100);
               else
         if (numClicks == 3)
         { g.setFont(largeFont);
            g.setColor(Color.YELLOW);
            g.drawString(myName, 100, 200);
       public void actionPerformed(ActionEvent move)
         repaint();
   }

You're putting your program logic in the paint method, something you should not do. For instance, try resizing your applet and see what effect that has on number of button clicks displayed. This is all a side effect of the logic being in the paint method.
1) Don't override paint, override paintComponent.
2) Don't draw/paint directly in the JApplet. Do this in a JPanel or JComponent, and then add this to the JApplet. In fact I'd add the button, the and the label to the JPanel and add the label to the JApplet's contentPane (which usually uses BorderLayout, so it should fill the applet).
3) Logic needs to be outside of paint/paintComponent. the only code in the paintComponent should be the drawing/painting itself. The if statements can remain within the paintComponent method though.
4) When calling repaint() make sure you do so on the JPanel rather than the applet itself.
For instance where should numClicks++ go? Where should the code to change the label go? in the paint/paintComponent method? or in the button's actionlistener? which makes more sense?

Invoking the paint repaint methods in Java2D

Hi,
This is the case:
I have used the paint method to a JPanel like this:
public void paint (Graphics g){
Graphics2D g2 = (Graphics2D) g;
g2.setPaint(gradientColor);
g2.fill(rect);
g2.setPaint(Color.white);
g2.drawString( "My label");
Now once the JPanel been painted, after a while,i want to change the

On implementingthe paint method, the panel does not up

Hi,
I have a panel over which i am adding a second panel.
the second panel appears but when i implement the paintmethod() of second panel, it does not show...
what can be the reason???
deepak

hi!
i included the statement super.paint(g); in the paint method and now i can see the panel.
Following is the paint() method i have written, the on;y problem left is that i can't see the images i had drawn...otherwise line and rectangles are coming fine
super.paint(g);
                    if(showImage)
                              Point pe0 = new Point(180, 110);
                              Point pe1 = new Point(180, 280);
                              Point p0 = new Point(138, 182);
                              Point ce0 = new Point(120, 75);
                              Point ce2 = new Point(240, 75);
                              Point ce1 = new Point(120, 380);
                              Point ce3 = new Point(240, 380);
                              g.drawImage(verticalCloudImage, (int)p0.getX() - 20, (int)p0.getY() - 85, this);
                              g.drawImage(peImage, (int)pe0.getX(), (int)pe0.getY(), this);

Adding a JButton when there's a paint method

I'm creating a game application, sort of like a maze, and I want to add buttons to the levelOne panel to be able to move around the maze. When I add the buttons to the panel they don't appear, I assume the paint method is the reason for this. here's my code, I have 3 files, ill post the user_interface, and the levels class, where the level is created and where i tried to add the button. I tried putting the buttons in a JOptionPane, but then my JMenu wouldn't work at the same time the OptionPane was opened. If anyone knows a way around this instead, please let me know. I also tried using a separate class with a paintComponent method in it, and then adding the button (saw on a forum, not sure if it was this one), but that didn't work either. Also, if there is a way just to simply have the user press the directional keys on the keyboard and have the program perform a certain function when certain keys are pressed, I'd like to know, as that would solve my whole problem. Thanks.

i tried adding a keylistener, that didn't work too well, i had tried to add it to a button and a textarea which i added to the 'one' frame, it didn't show up, and it didn't work. How would i go about changing the paint method so that it doesn't contain any logic? That's the only way I could think of getting the program to move forward in the game. Thanks.

How to use an object's paint method

I have created a class imagePanel which extends a jPanel to display an image. When I create a new imagePanel object I pass it an image argument which is used to paint my image on the jPanel, so far so good. I don't wish to have to continuously create new ImamePanels to display new images so I thought I could make a set_Image method that would set a new image in an exising imagePanel object. This is where I run into problems how to use the existing object paint method to replace the image. I tried this without success:
public Image setMyImage (Image myImage)
imageX = myImage; // imageX is the image that is painted by the imagePanel object's paint method
paint(g);
Something must be wrong on how I access the paint method. Thanks for any help.

Yahoooo, got it. This was the code I needed and thanks for your help:
public void setImage (Image myImage)
imageX = myImage;
repaint(300);
}

Where is the paint method?
