I have a JTable with very large font in it. I am trying to format the text in a cell editor to match the rest of the table.
Looking at Sun's web page for CellEditor http://java.sun.com/j2se/1.4.2/docs/api/javax/swing/CellEditor.html makes me think that it just does not support formatting features, so I am thinking that I need to make something fit over the cell (like a JTextField) that has the ability to setFont. Is this the easy, or right way to do this?

It looks to me like you are doing real good, so I don't understand what you are having problems with. Adding two and subtracting one seems so simple, maybe I am missing something?

if((die == die2)&&(die == die3)) { result="win"; money += 2; } else { result = "sorry you lose" ; money--; if(money <1) { System.err.println("Game over, you are broke!"); return; } }

Also you may want to use code tags to make your code easier to read.

>> Any of them sound like something you can do?

No, but I got all day and plenty of google left...

Thanks for giving me a place to start looking and learning.

I want to return from a long function if the user presses any key.

This is sort of what my program looks like...
private void jTable1KeyReleased(java.awt.event.KeyEvent evt) { // update data based on key pressed // this function is not called till heavyCrunch() finishes } public class AttributiveCellRenderer extends javax.swing.JLabel implements javax.swing.table.TableCellRenderer {... // update my GUI // I want this function to abort and return if user presses a key heavyCrunch(); return; }

I have been looking in keyEvent, concurrence and threads etc. but it seems
like one should be able to just put in an if statement that asks if a key
has been pressed and then simply call return.

Any ideas on the right way to do this would be most welcome.

Okay it works (sort of).
Java is easier than I thought it would be.
And here is my next problem.
My simple program will download the text of a web page and save it to a .txt file, as long as I do not need a password to access the page.
So how do I include my user id and password info to get access to the pages that are password protected?

For now I am trying to get into my Yahoo! mailbox.
Here is what my code looks like so far.

import java.io.*; import java.awt.*; import java.net.*; import java.awt.event.*; import javax.swing.*; public class ReadList extends JFrame implements ActionListener { public ReadList(String title) { super(title); String line = readURL("http://www.yahoo.com/"); saveStringToFile( "c:/yahooFile.txt", line ); // This works fine since no password is required // I get to -> <title>Yahoo!</title> and the text // is saved to "c:/yahooFile.txt" // I copied the url of my mailbox to see if I could get there // but it would not work String line2 = readURL("http://us.f523.mail.yahoo.com/ym/login?.rand=1ndrg7ajiie7g"); saveStringToFile( "c:/yahooMailFile.txt", line2 ); // I want to get this page -> // <title>Yahoo! Mail - olavisjo@yahoo.com</title> // But without a password all I get is this -> // <title>Yahoo! Mail</title> } public static void saveStringToFile(String filepath,String text) { try { // check if file exists; if not create it File file=new File(filepath); if( ! file.exists()) file.createNewFile(); // write file PrintWriter out=new PrintWriter(new BufferedWriter(new FileWriter(filepath))); out.write(text); out.close(); } catch(Exception e){ e.printStackTrace();} } public void actionPerformed(ActionEvent e) { //useless function but seems to be necessary to overide something. } // In this method, we create a BufferedReader to // read efficiently from a URL. // We keep reading from the BufferedReader until // there are no more characters to // read. The characters are read into a buffer // which is then added to an array. // After all of the characters are in an array, we // convert the characters to a String. private String readURL(String url) { try { BufferedReader input = new BufferedReader(new InputStreamReader(new URL(url).openStream())); char[] chars = new char[0]; char[] buffer = new char[4000*1024]; int length = 0; while ((length = input.read(buffer,0,buffer.length)) != -1) { char[] temp = new char[chars.length+length]; System.arraycopy(chars,0,temp,0,chars.length); System.arraycopy(buffer,0,temp,chars.length,length); chars = temp; } input.close(); return(String.valueOf(chars)); } catch (IOException ie) { return(" readURL error "); } } public static void main(String[] args) { ReadList readList = new ReadList("ReadList"); } }

So much help and so little time.
Thanks for all the information, it is more than I expected, it will keep me busy (happy) for a long time. As bad as I am at programming, I just love it more than anything.

thanx again

Every day I use I.E. and go to about 30 web pages and I click "Select All" then "Copy" and then I "Paste Unformatted Text" into my word processor and then I "save as text file" after which I can use C to parse through the text file to get the data I am after.

Needless to say that navigating to 30 pages per day is very tedious, so I would like to write a JAVA program to automate this process for me.

This does not sound like a difficult thing to do but since all I know about JAVA I learned from Starbucks, I will need a little help to know where to get the information I need to start this project.
Any help is appreciated as I have spent hours wandering the Internet without getting any smarter.

thanx
