Thread: Another printing topic

Hey guys,
I know I'm new and all (And most of you will hate me for doing this).
But I got one small problem with printing.

As you see, i made my very own notepad. And I'm kinda stuck with getting the text from the user into the picture.

//Global variable for the text. String textPrint;   private void printMenuActionPerformed(java.awt.event.ActionEvent evt) { textPrint = text.getText(); //text = the user input PrinterJob pj = PrinterJob.getPrinterJob(); PageFormat pf = pj.defaultPage(); Paper paper = new Paper(); double margin = 36; // half inch paper.setImageableArea(margin, margin, paper.getWidth() - margin * 2, paper.getHeight() - margin * 2); pf.setPaper(paper);   pj.setPrintable(new notepad(), pf); if (pj.printDialog()) { try { pj.print(); } catch (PrinterException e) { System.out.println(e); } }   }       public int print(Graphics g, PageFormat pf, int pageIndex) { if (pageIndex != 0) return NO_SUCH_PAGE; Graphics2D g2 = (Graphics2D) g; g2.setFont(new Font(FontPrint, Font.PLAIN, fontS)); g2.setPaint(Color.black); g2.drawString(textPrint, 100, 100); return PAGE_EXISTS; }

When I use this method, I get blank sheet that gets printed. No errors.
The problem lies with the variable and i don't know a way around it.

^ would this work?

i tried it yesterday, doesnt work :/ just prints the line together.

Here is the code:

it follows this:
Make a new file with the data on it
open file
make a scanner
make a while loop that will read the text on it
then String data = data + "/n" + x.nextLine();
then use
private void drawString(Graphics g, String text, int x, int y) {
for (String line : text.split("\n"))
g.drawString(line, x, y += g.getFontMetrics().getHeight());
}
once all this is done, delete the file.

norm, the code i showed earlier makes a file with the text from the text area and then reads the file with it. i did this to use the x.next() method for the while loop and make so i can have this algorithim in it: data = data + x.nextline(). i hope you understand what i mean.

yea but the thing is, if i hard code a string it wont work the way i want it to. as you can see, i want the user to print all text on the text area.
im trying to make the program atm print out the lines, instead of it just giving it as one line.
norm do you have any other methods i could try?

I think i need to do another approach to the printing method, does anyone else have another way in which i could try?

norm, my problem is i cant figure out a printing method where it will print multiple lines and keep within the margins at the same time.
so atm i dont know how :S

Soz norm for the long wait for my reply. I was away for easter and came back to see my pc was broken. All fixed now.


Ok so can you help me through this?

ill start of, can you guide me through this please?

public class JavaPrint implements Printable{   }

Ok, im trying to make a notepad, and i am trying to get the print method to work as i want it to.

1) Must print multiple lines
2) Must print within a certain area
3) Must print more than one line.

But I keep getting errors where 1) doesn't even work.

ok so i dont get syntax errors, just visual errors.

Say like i type into the text area:

Hello my name is slim shady.
Hello

it will repeat itself multiple times(on top of each other.)


Here is the method:
