So where is your code? What have you tried?

I tried your code with one of the demo plots and it worked just fine. Are you setting the series paint colors after you have added all of the series to your dataset?

Did you try it? Did it work?

If you insist on using a GUI designer for everything then you'll probably have to use card layout, as efxee mentioned above.

That's not a question. Ask something comprehensible or stop wasting peoples' time.

If you have separate panels for each group of controls, you can simply swap those in and out of a target panel that remains in a fixed place in your UI.

To swap them, remove the old panel, add the new, and call targetPanel.revalidate() and targetPanel.repaint().

A text editor?

I'm not really certain what the question even is. It just sounded vaguely like he was asking for some kind of installer.

You could use IzPack to create an installer for your program.

Would you like to rephrase that to something comprehensible?

Who knows? You didn't post the tester class.

Seriously? You resurrected this 2-year-old thread to post that? Did you even bother to read the rest of the posts?

Fates Warning - Point of View

Read the docs or forums I suppose. I have no idea if that will allow you to use the Access ODBC driver. Maybe their FAQ will help?

I'll just reiterate my suggestion to use a different database if you want to work on Mac.

No, Java has no drivers for Access. You are currently using the JDBC/ODBC bridge driver, which allows JDBC connection through a separately installed ODBC driver.

> do I have to install Access on my mac
You need the ODBC driver for Access. There are third-party vendors that sell them, though I'm not sure if there are any free options available to you.

Maybe you could switch to JavaDB or H2 instead?

Please elaborate. "Many errors" doesn't give anyone much to work with.

You didn't post a question.

Please do not create multiple threads for a single question. Closing this one to forestall two active threads on this.

What is your specific question?

With a null layout, use setLocation() or setBounds().

Alright, maybe this will clarify a bit:

1) main method must be wrapped into invokeLater()

For concurrency reasons, GUIs should be created on the event dispatch thread. In your main method, you should create your GUI instance in a small Runnable that can be executed on the dispatch thread

javax.swing.SwingUtilities.invokeLater(new Runnable() {
            public void run() {
                new TableFrame();
            }
        });

3) don't call fireXxxXxx outside AbstractTableModel

Your model should fire those events itself as needed when the data changes.

5) don't create/recreate JTable inside Model,

I don't see where your latest code is doing this, so I'm not sure why that was mentioned.

mKorbel already mentioned a few changes above. If you don't understand some of them, just ask for some clarification.

Personally I would also move the methods that build or update your model data into the model class itself and expose a method like addRow() for your GUI to call when the button is clicked.

You are updating your local 'data' array in the frame - not the one in your table model.

HTML is a markup language. It is not a scripting language.

Don't know why another thread was necessary:
http://www.daniweb.com/software-development/c/threads/385432

I believe he was referring to the removing and recreating all of your components each time instead of merely updating the data they contain. Update the data in your table model. You don't have to throw everything away.

Has advanced search simply moved or gone away entirely? It looks like search has changed a bit and I can't seem to get to the advanced search screen.

From your code above, it looks like you're showing the file name in a dialog just before opening

JOptionPane.showMessageDialog(null,outFileNamePDF);

Can you check the read/write permissions on that location?

Netbeans created build and dist folders for the files that it generates. I'm not sure how ownership and permissions are set on those. I've never used Ubuntu in my life, so I couldn't tell you how to check them.

Have you checked the file permission on the location you're showing for 'outFileNamePDF'?

Folder permissions are the likely culprit. Is the exception giving you any more information?

Unless you're allowed to use the Math.floor() function, which seems unlikely, you need to keep only the integer portion of your divisions.

In your case of 32/20, you can't use the 0.608 portion, you can only return 1 bill. You can't round it because then you're giving back too much. You must discard the decimal portion of that calculation.

And the reason is that bills and coins are integer quantities - not floats. Treat them as such.

Consider that bills and coins are not fractional. They are whole integers.

Do the standard IDEs have options that would warn about the condition?

Yes, Netbeans warns you of that.

When do you ever want to shadow a class level variable with a local definition?

No good case for it really comes to mind. It's just likely to cause confusion at the least and hard to spot bugs at worst.

I guess the one exception that is somewhat common is parameters of the same name in constructors, where the local variable is qualified with 'this'.

Why isn't that a warning from the javac.exe program?

No idea.

Post your current code and explain which part you are having trouble with.

> Am believing that He'll certainly speak through DANIWEB
You'll find a lot of speaking if you use the search feature. There are thousands of "final year project" threads. After you have read them, post back if you have a specific question.

This thread was happily sleeping in 2007 before Niluk decided to hijack and resurrect it for a completely unrelated question.

I'm going to close it here since I imagine the OP has solved his question.

It seems pretty obvious from this post that he is irritated that you bailed out of this ongoing thread and started a new one to go in some other direction.

You could use a math package like javax.vecmath, which has several matrix classes with invert() methods or you can do the math yourself. You can find the math easily on the net.

> Can someone help me?

Not if you don't ask specific questions.

Glad you got it working.

For future reference, you can right align drawn strings like this

int fahrCol = 40;
String fahrString = (int) farhen + "\u2109";
int fahrStringWidth = g.getFontMetrics().stringWidth(fahrString);
g.drawString(fahrString, fahrCol-fahrStringWidth, row);

You can truncate the decimal portion by simply casting the variable to an int

(int)cels

If you want to round, you can use DecimalFormat or the String.format() method.

Agreed. Mine was merely a note on future simplification once he gets the image display issue resolved.

Thank efxee, I just agreed with his/her suggestion. :)

Unrelated note on the code:
These code blocks only seem to vary by the image offset

BufferedImage img = (BufferedImage) Toolkit.getDefaultToolkit().getImage("Images/image.png");
			character = img.getSubimage ((32 * animationNumber), (32 * offset), 32, 32);
			animationNumber ++;
			if (animationNumber == 4){
				animationNumber = 1;
			}

so you could easily factor out all that repeated code. It's also unlikely that you need (or want) to reload your images constantly as your animation runs.

Nope, wouldn't matter. JPanel, JLabel, or even just an extension of JComponent.

Look at all of the identical code in your if-else cases. The only part of those code blocks that varies is the setColor() call. The rest is executed for every case, so it doesn't need to be in your if() blocks. Don't repeat more code than you need to.

For your 'cel' calc, be careful about mixing integers with float division. 5 and 9 are ints, so consider how that impacts your formula result.

To change the alignment, you'll have to change where you draw the strings. That may involve some calculations on the string lengths as well. You can check this entry in the Java 2D graphics tutorial about measuring text: http://download.oracle.com/javase/tutorial/2d/text/measuringtext.html

After you get it to compile, consider that the only part of your code that will be different in all of those if-else cases is the check for which color to use.

You don't need to repeat all that code in each case. Just check the current value of 'faren' and set your color.

Also note that Applets don't use a main() method. Just remove that.
