Javapad 2.0

[Eku]

Attach here the Beta Version of Notepad with some Java Features.

Contains Basic Features of a Notepad. Except the Print feature is not yet working. (Can someone send me a printing function =))

Contains Extra Features such as Build, Run, Open-Command Line (Must have java_home and Java declared in the environmental variables) (Works in Windows but not yet tested in other platforms)

Feel free to email me your reactions/proposed feature/Bugs and error.
This is my contribution to the Java Community. =)

I've tested your program....

Win XP SP3
Im using jdk 6 update 3
bin path already set

Build and Runtime error. why? using Runtime? or JavaCompiler class?

I suggest you shall create a documentation about your program. How should specifically use it, its condition before using it, and EULA ( detailed )...

Not bad, keep it up.....

Here is a simple PrintData Class, it will print a page.

public class PrintData implements Printable{
    private Component data;
    
    public PrintData(Component e){
        this.data = e;
    }
    
    public void setValue(){
        new PrintData(data).initializePrint();
    }
    
    public void initializePrint(){
        PrinterJob proceed = PrinterJob.getPrinterJob();
        proceed.setPrintable(this);
        if(proceed.printDialog()){
            try{
                proceed.print();
            }catch(Exception e){
                JOptionPane.showMessageDialog(null,"AN ERROR OCCURED WHILE INITIALIZING PRINTER");
            }
        }
    }
    
    public int print(Graphics g, PageFormat format, int page){
        int value = Printable.PAGE_EXISTS;
        Font pattern = new Font("Arial",Font.PLAIN,10);
        if(page>0){value = Printable.NO_SUCH_PAGE;}
        Graphics2D g2D = (Graphics2D)g;
        g2D.setFont(pattern);
        g2D.translate(format.getImageableX(),format.getImageableY());
        data.setFont(pattern);
        data.paint(g2D);
        return value;
    }
}

where Component e should be the source of text ( TextArea for example )

WAW thanks a lot. I really appreciate it. =)
I just used the command line in Compiling. Here is the Command i used. i just cut it from the main code. I just invoke the Javac and java commands. One more problem is how do i Handle those errors in compiling. I will read the compilerClass, thanks for informing that, Im still have lots to learn about java. =)

else if (command.equals("Build")) {
            try
            {   File filename2 = new File(filename.getAbsolutePath().substring(0,filename.getAbsolutePath().lastIndexOf(".")));
                
                String s ="javac -cp \""+ filename2.getAbsolutePath().substring(0, filename2.getAbsolutePath().lastIndexOf("\\"))+"\" \""+ filename2.getAbsolutePath() +".java\"";
                Runtime.getRuntime().exec(s);
                JOptionPane.showMessageDialog(this,"Building Succesful");
            }
            catch (Exception ex){ System.err.println(ex);
            JOptionPane.showMessageDialog(this,"Building Error");}
        }
        else if (command.equals("Run")) {
            try
            {   File filename3 = new File(filename.getAbsolutePath().substring(0,filename.getAbsolutePath().lastIndexOf(".")));
                String s ="cmd.exe /k start java -cp \""+ filename3.getAbsolutePath().substring(0, filename3.getAbsolutePath().lastIndexOf("\\"))
                        + "\" "+ filename.getName().substring(0,filename.getName().lastIndexOf("."));
                Process process = Runtime.getRuntime().exec(s);
                BufferedReader stdout = new BufferedReader(new InputStreamReader(process.getInputStream()));
                JOptionPane.showMessageDialog(this,"Run Succesful");
            }
            catch (Exception ex){ System.err.println(ex);
            JOptionPane.showMessageDialog(this,"Run Time Error");}
        }else if (command.equals("Open Command Line")) {
            try
            {  Runtime.getRuntime().exec("cmd.exe /k start cd \\");}
            catch (Exception ex){ System.err.println(ex);
            JOptionPane.showMessageDialog(this,"Run Time Error");}
        }
