creating motif logo

Posted: May 14, 2014 10:00 PM

I am trying to create a motif logo taking input from file and the output will show the result in the textarea. Here, input can be taken but output is not shown. I have done the code as follows:

public class Loogo extends JFrame {

Container c = getContentPane();
int lng1, lng2, i, j;
JLabel l1, l2, l3, l4;
JTextField t1, t2, t3, t4;
JTextArea t5;
//int match=5,gap=-4,mismatch=-3;
JButton b1, b2, b3, b4;
String s1, s2, s3, s4;
String output;

public Loogo() {
l3 = new JLabel("NiddlemanWunch Algorithm.");
c.add(l3);
l1 = new JLabel("1st sequence");
l2 = new JLabel("2nd sequence");
l3 = new JLabel("3rd sequence");
l4 = new JLabel("4th sequence");
t1 = new JTextField(20);
t2 = new JTextField(20);
t3 = new JTextField(20);
t4 = new JTextField(20);
t5 = new JTextArea(20, 20);
b1 = new JButton("upload 1st sequence file");
b2 = new JButton("upload 2nd sequence file");
final JButton b5 = new JButton("Motif");
b3 = new JButton("upload 3rd sequence file");
b4 = new JButton("upload 4th sequence file");
FlowLayout f = new FlowLayout();
c.setLayout(f);
c.add(l1);
c.add(t1);
c.add(l2);
c.add(t2);
c.add(l3);
c.add(t3);
c.add(l4);
c.add(t4);
c.add(b1);
c.add(b2);
c.add(b3);
c.add(b4);
c.add(b5);
c.add(t5);
Font font = new Font("Courier", Font.PLAIN, 20);
t3.setFont(font);
b1.addActionListener(new ActionListener() {

public void actionPerformed(ActionEvent ae) {
JFileChooser fj = new JFileChooser();
fj.showOpenDialog(null);
fj.setFileSelectionMode(JFileChooser.FILES_ONLY);
File fe = fj.getSelectedFile();
try {
FileReader reader = new FileReader(fe);
BufferedReader br = new BufferedReader(reader);
t1.read(br, null);
br.close();
} catch (Exception e2) {
System.out.println(e2);
}
}
});

b2.addActionListener(new ActionListener() {

public void actionPerformed(ActionEvent ae) {
JFileChooser fj = new JFileChooser();
fj.showOpenDialog(null);
fj.setFileSelectionMode(JFileChooser.FILES_ONLY);
File fw = fj.getSelectedFile();
try {
FileReader reader = new FileReader(fw);
BufferedReader br = new BufferedReader(reader);
t2.read(br, null);
br.close();
} catch (Exception e2) {
System.out.println(e2);
}
}
});
b3.addActionListener(new ActionListener() {

public void actionPerformed(ActionEvent ae) {
JFileChooser fj = new JFileChooser();
fj.showOpenDialog(null);
fj.setFileSelectionMode(JFileChooser.FILES_ONLY);
File fe = fj.getSelectedFile();
try {
FileReader reader = new FileReader(fe);
BufferedReader br = new BufferedReader(reader);
t3.read(br, null);
br.close();
} catch (Exception e2) {
System.out.println(e2);
}
}
});

b4.addActionListener(new ActionListener() {

public void actionPerformed(ActionEvent ae) {
JFileChooser fj = new JFileChooser();
fj.showOpenDialog(null);
fj.setFileSelectionMode(JFileChooser.FILES_ONLY);
File fw = fj.getSelectedFile();
try {
FileReader reader = new FileReader(fw);
BufferedReader br = new BufferedReader(reader);
t4.read(br, null);
br.close();
} catch (Exception e2) {
System.out.println(e2);
}
}
});

b5.addActionListener(new ActionListener() {

private int colorIndex;

public void paint(Graphics g) {
char c1 = ' ';
char c2 = ' ';
char c3 = ' ';
char c4 = ' ';

s1 = t1.getText();
s2 = t2.getText();
s3 = t3.getText();
s4 = t4.getText();
int l1 = s1.length();
colorIndex = 0;
c1 = s1.charAt(i);
c2 = s2.charAt(i);
c3 = s3.charAt(i);
c4 = s4.charAt(i);
Point loc = new Point(10, 10);
for (int i = 0; i < l1; i++) {
if (c1 == c2 && c1 == c3 && c1 == c4) {

if (c1 == 'A') {
g.setColor(Color.black);
} else if (c1 == 'T') {
g.setColor(Color.red);
} else if (c1 == 'G') {
g.setColor(Color.blue);
} else if (c1 == 'C') {
g.setColor(Color.green);
}
Font f = new Font("TimesRoman", Font.PLAIN, 72);
int width = g.getFontMetrics().charWidth(c1);
g.drawString("" + c, loc.x, loc.y);
loc.x += width;

}
}
}

public void actionPerformed(ActionEvent ae) {
t5.setEditable(true);

if (ae.getSource() == b5) {
repaint();
}

}
});
setVisible(true);
setSize(500, 600);
}

/**
* @param args the command line arguments
*/
public static void main(String[] args) {
Loogo l = new Loogo();
// TODO code application logic here`enter code here`
}
}
