How paint method in TiledLayer work ?
It's my 1st time in forum. Does anyone has source code of Sprite, TiledLayer class or know how exactly the paint method work? I had used it in some game but not satisfied with it. I want to code my own class but i wonder it has some native or low-level code.
Sorry for my poor E !!!
perhaps you want to use a more hardware oriented approach. I can highly recommend you the Slick API. It is built on top of the LWJGL API set, which is a Java binding for OpenGL, OpenAL and provides device support such as joysticks/joypads. Slick turns the 3D part into an easy to use 2D rendering framework.

Help with 2D Graphics - How do I send Variable data to paint method?
I am working on a program that figures mortgage payments and an amortization schedule when a user inputs the principle, APR, and term length in years. After it figures all of those, I want to be able to display a chart that shows the principle and interest amounts for each year. My problem is, how do I get my loan information into my paint method so that I can draw a chart using that data? Any help would be greatly appreciated. The graph class in the code below is called after pressing a "Display Graph" button from my GUI.
I'm pasting my code below. This does not include my main method or my GUI method. I can post those if necessary. Here is my code so far:

My email address iss [email protected] if you wish to reply privately. I can send my entire program code if that will help. Thanks!Hi Deca,
You can use the CmdExecuteSync method of the DIAdem.TOCommand interface to set the value of a text channel. For example passing the string "CHT(1,1) := 'test'" as a parameter to the CmdExecuteSync method will set the 1st row of the 1st channel to "test". Please refer to the DIAdem help for more documentation on the CHT function.
I hope this helps! Please post back if I wasn't clear enough in explaining how to do this or if you have any problems getting it to work.
Regards,

I cannot figure out how to make the text larger in a received email. The finger method doesn't work and I can find no tool bar as I can for composing emails. I can find nothing in settings. Please help and thank you in advance.
Hi there,
Download a piece of software called TinkerTool - that might just solve your problem. I have used it myself to change the system fonts on my iMac. It is software and not an app.
Good wishes,

I plug my iphone 3gs into my laptop and it no longer syncs with my iTunes. I've tried all the trouble shooting methods and nothing works. My iPhone doesn't appear on iTunes or under "My Computer." Does anyone know how to fix this?
If AMDS is running, you are using a USB port directly on the computer and not a hub, you have disconnected other USB devices except keyboard and mouse, you have completely uninstalled and reinstalled iTunes as described in http://support.apple.com/kb/HT1925, You have tried cleaning the connector on the bottom of the phone, you have tried a different cable, you have installed the latest USB drivers for your computer, you have disabled your antivirus and firewall, you are running as an Administrator account and you have tried creating a new user on your computer and connected when logged in as that user then you have exhausted my knowledge. The only other thing to try is a different computer. If it isn't recognized on a different computer you have a hardware problem. Good luck!

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

SetBounds method is not working - settings change after Applet paint()
Hello,
I'm creating an applet with a scrollbar on it. I'm using Scrollbar.setBounds to set its position and dimension. These values are correct at the end of the init() method, but when the paint() method starts executing, these values have changed!
Here's my code :
import java.awt.Graphics;
import java.awt.Scrollbar;
public class testSetBounds extends java.applet.Applet {
Scrollbar sb;
public void init(){
sb = new Scrollbar(Scrollbar.HORIZONTAL, 0, 1, 0, 270);
sb.setBounds(10, 200,300,10) ;
this.add(sb);
System.out.println("sb.getWidth() " + sb.getWidth() );
System.out.println("sb.getBounds().x " + sb.getBounds().x ) ;
public void paint(Graphics g){
System.out.println("paint...") ;
System.out.println("sb.getWidth (at start of paint()) " + sb.getWidth() );
System.out.println("sb.getBounds().x " + sb.getBounds().x ) ;
System.out.println("sb.getMaximum() " + sb.getMaximum()) ;
<html>
<body>
<applet code="testSetBounds" codebase="classes" width="300" height="350">

The output I get on the Java Console is:
sb.getWidth() 300
sb.getBounds().x 10
paint...
sb.getWidth (at start of paint()) 50
sb.getBounds().x 125
Can anyone tell me what's going on?

How to use paint method to draw in many componets.
Hi!
I have code like this:
public class MainPanel extends JPanel{
JPanel p1;
JPanel p2;
public MainPanel(){
super(new BorderLayout());
p1 = new JPanel();
p2 = new JPanel();
add(p1 , BorderLayout.Center);
add(p2 , BorderLayout. West);
setVisible(true);
@Override
protected void paintComponent(Graphics g) {
g.setColor(Color.red);
g.fillrect(10,10,10,10);
}This code is onle an example. Supose, this code will paint black rectangle on "main panel" to which p1 and p2 are added. What should i do to be able to paint this rectangle on p1 or p2 without creating separate classes in which i will override paintComponents() method for p1 and p2. I would like to avoid creating separete classes for each panels. Is there any way to do that using one paint Components method. Thanks in advance for all respone.(where's Darryl when you need him?)Erm, Pete, since when did I become an expert lol?
Lost my hard disk, its been hiccuping for a couple of weeks now. I'm running on an old 20 GB PATA with a 5GB c drive. No IDE, no offline Javadoc. I'll get a HDD in the morning, but I hope I can spin up the old disk at least once and recover the last week's "work" ... just fun stuff actually.
Why does this code draw rectangles just for split second?repaint() (and consequently paint(), paintComponent() and other painting methods) may be called by the system any time it is detected that the component needs to be repainted. Since you do not have a override for paintComponent, it will perform its default painting and paint the entire component, wiping out your rectangle.
For persistent drawing on a JPanel or JComponent I know only one way: override paintComponent. If you need to avoid this, you could go with morgalr's suggestion to use JLabel.
For this you would draw the triangle/rectangle/whatever to a BufferedImage, then call label.setIcon with a new ImageIcon constructed from the BufferedImage.
Also, avoid obtaining a Graphics reference via getGraphics. During the lifetime of a visible component, various different Graphics references may be passed into the paintComponent method, so the reference you obtain may not be current. getGraphics can also return null.

My pay method has stopped working so that I can no longer purchase and/or download any apps or products onto my iPad. It is saying "there was a problem with a previous purchase. Use another pay method. What does this mean, and what do I do?
Further, in my attempts to correct the situation, I reset my iPad, resulting in my losing all the apps that I downloaded, and all the products I had bought and downloaded. How do I recover all of them (magazines, books, apps, etc).
Please, help.
Victor KalalaLook, I understand I still need a card attached to the account. The problem is, it won't accept my card because I only have 87 cents in my bank account right now.
If I had known there would be so much trouble with the iTunes card, I would have just put the cash in my bank account in the morning instead of buying an iTunes card (I didn't expect the banks to be open on Thanksgiving of course).
Apple will only accept cards that have a balance. The balance is so small in my account that it won't accept it as a valid card.
I'm going to have to contact Apple anyway to reset the security questions. That's obvious. Your answers were not exactly helpful. You didn't tell me anything I don't already know, but thanks for trying to be helpful. -
Confused by how Paint Brushes Work
I draw a rectangle in object mode, and using the Brush Mode
options:
a) paints fill paints behind the shape. What is considered
the fill in this example?
b) paints inside, seems to paint inside the shape, however,
if I start painting outside the shape and into the shape, the
stroke appears only outside of the shape and not inside.
When drawing the shape in non-object mode:
a) Paints fill paints both on top and outside of the shape
b) paints inside, seems to paint inside the shape, however,
if I start painting outside the shape and into the shape, the
stroke appears only outside of the shape and not inside.
Can anyone clarify how this is supposed to work?

How to add more than one paint method
hi everyone
I am doing a project in which i have already created a paint method but i find that there is necessity to create one more
paint method within the same file in which i have a paint method pls tell me how to how to add a paint method how to call the repaint method
please its very urgentBy even suggesting that I can gather you have a horrible design of what ever you are doing--DON'T! And go back and refactor your application so you do not need or even want such a thing to happen.
1 - paint is for use in AWT. If you are using AWT, then very well, you are at least using the right method to override. If you are using SWING, then you are totally messed up before you even arrived at this ill conceived plan of 2 paint methods.
2 - your paint (AWT)/paintComponent (SWING) is a system called method driven by events you haven't any control over. You need to treat it as such.
3 - your painting method should be very tight. I will bet your's is a horrid mess: overstuffed with attempted control and logic processes.
4 - Even if you are using active rendering, your approach to 2 painting methods is horrible at best.
If you need help in designing your process better, then post what you have and ask for help. IMO what you are doing can only lead to ugliness. -

blazeds/trunk/modules/core/src/java/flex/messaging/io/BeanProxy.javaAs I said in your original post, iTunes U is not available to any institution, government or otherwise, in South Korea. If or when Apple will extend iTunes U to your country is something none of us here can say, and Apple will not until such time as they're ready to make an announcement. What Apple's criteria and requirements are for being able to open iTunes U in a given country is unknown; there is no "procedure" that any of us here can state or direct you to that you could initiate. It's totally up to Apple, and if they are working on this, I'm sure they know who in the SK government they would need to work with.
Sorry, but you will just have to wait and hope that something develops in the future.

How seek method works actually??
Hi,
i am not able to understand how seek method works in java.
plz make me clear on this method..
seek(pos)
The position in the file where the next read or write operation will occur.
But it operates entirely different in the following code. only when i put the value as 5 , it prints the value of 7890. if i pass anything other than that, it would return some values which were not written.
import java.io.*;
public class TestIPApp {
public static void main(String args[]) throws IOException {
RandomAccessFile file = new RandomAccessFile("c:\\test.txt", "rw");
file.writeBoolean(true);
file.writeInt(123456);
file.writeInt(7890);
file.writeLong(1000000);
file.writeInt(777);
file.writeFloat(.0001f);
file.seek(9);
System.out.println(file.readInt());
file.close();
}when i open the test.txt file, it contains some junk values. how could i see this txt file in readable format?
plz help mePannar wrote:

Boolean values are written [in one byte|http://java.sun.com/javase/6/docs/api/java/io/RandomAccessFile.html#writeBoolean(boolean)], int values are written [in four bytes|http://java.sun.com/javase/6/docs/api/java/io/RandomAccessFile.html#writeInt(int)]. Positioning the file pointer to the fifth byte gets ready to read the next int value.
In your code, however, you move the pointer to the ninth byte, which is the start of what you wrote as a long value. So, this code...System.out.println(file.readInt());...should be this:System.out.println(file.readLong());

"the other methods aren't working"
Well, what other methods have you tried that didn't work? Frankly, your post reads as a hoax, but I have some extra time on my hands, and an idea. Make an appointment with the Apple Genius at your local Apple store. You could also bring your MBP to an AASP. Regardless, either one should be able to remove the bottom cover, and use a plastic thingy (dang, what is that tool called?) to push out the offending bit.
