JLabel + GUI problem

[tonyelaltaico]

Hello


I have a JLabel2 which shows the spanish map. The thing is I do wanna draw lines on my spanish map and save it to as an image file in my desktop . I'm able to draw lines and save my JLabel2(spanish map) as an image in my Desktop. The problem is I'm not able to see any lines that I draw before in my image file. I can see those lines when I do click draw button but I can not see them when I save my file as an image to my desktop.Please help me.This problem killed me for two days..you can see how i converted to icon and how i save it as an image file below.Thank you for your helps from now.


private void jButton3ActionPerformed(java.awt.event.ActionEvent evt) {

File file3;

int returnVal = fc.showSaveDialog(routemap.this);
if (returnVal == JFileChooser.APPROVE_OPTION) {
try {
File f3 = fc.getSelectedFile();
ImageIcon icon = (ImageIcon) jLabel2.getIcon();
System.out.println(icon.getIconHeight());
BufferedImage buf = new BufferedImage(icon.getImage().getWidth(
null), icon.getImage().getHeight(null),
BufferedImage.TYPE_INT_RGB);
buf.getGraphics().drawImage(icon.getImage(), 0, 0,
icon.getIconWidth(), icon.getIconHeight(), null);
ImageIO.write(buf, "jpg", new File(f3.getAbsolutePath()
+ ".jpg"));
System.out.println(f3.getAbsolutePath());

} catch (IOException e) {

}

}
}



I have drawn lines by using draw function as you see below and I can not see those lines without any problem..Lines disapper in the image file when I do save it..Here is the draw button..

private void jButton5ActionPerformed(java.awt.event.ActionEvent evt) {
boolean go = true;
if (OneClicked == false && go == true) {
jLabel3.setText(jComboBox1.getSelectedItem() + " to ");
view = jComboBox1.getSelectedItem().toString() + " to ";
String m = jComboBox1.getSelectedItem().toString();
int size1 = City.size();
for (int i = 0; i < size1; i++) {
if (City.get(i).equals(m)) {
Index.add(i);

}

}
OneClicked = true;
go = false;

}
if (OneClicked == true && go == true) {
jLabel3.setText(view + jComboBox1.getSelectedItem());
view = "";
String m = jComboBox1.getSelectedItem().toString();
int size1 = City.size();
for (int i = 0; i < size1; i++) {
if (City.get(i).equals(m)) {
Index.add(i);
}
}

Graphics g = jLabel2.getGraphics();
g.setColor(Color.BLUE.darker());
Graphics2D g2 = (Graphics2D) g;
g2.setStroke(new BasicStroke(3));

System.out.println(Index.size());
System.out.println(Index.size() - 2);
int m1 = Integer.parseInt(XCoordinate.get(Index
.get(Index.size() - 2)));
int n1 = Integer.parseInt(YCoordinate.get(Index
.get(Index.size() - 2)));
int m2 = Integer.parseInt(XCoordinate.get(Index
.get(Index.size() - 1)));
int n2 = Integer.parseInt(YCoordinate.get(Index
.get(Index.size() - 1)));
System.out.println(m1 + " " + n1 + " " + m2 + " " + n2);
g2.drawLine(m1, n1, m2, n2);
OneClicked = false;

}
System.out.println("index im" + Index);
}

And tested the slangword filter to breaking point on the Sun forum.

You're drawing on the JLabel, not the JLabel's icon. I suggest you get the BufferedImage behind the label first, and then draw onto that. Then you will both be able to display and save the BufferedImage.

It's still same OrangeDog :(.

What's your new code look like? It should be significantly different to the old code.
