JLabel with Image?
Question
Honestly, I am not that familiar with GUI and I'm still having a study about it. My question is, how can I combine an image and a label? I want to have an output that there's a text above the picture. Here's the code I got from a reference
import java.awt.Container;
import java.awt.EventQueue;
import javax.swing.ImageIcon;
import javax.swing.JFrame;
import javax.swing.JLabel;
class JavaApplication2 extends JFrame {
public JavaApplication2(String title, String imageFileName) {
setTitle("title");
ImageIcon icon = new ImageIcon(imageFileName);
Container pane = getContentPane();
JLabel label = new JLabel(icon);
pane.add(label);
}
public static void main(String[] args) {
EventQueue.invokeLater(new Runnable() {
public void run() {
JFrame f = new JavaApplication2("Orca","C:/Users/Balmaceda/Desktop/Naomi
/Capture.png"); //change pic here
f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
f.pack();
f.setVisible(true);
}
});
}
}
and this thing here:
JLabel label = new JLabel(icon);
everytine I change the (icon) into ("icon"), only the word icon is displayed on the window. The picture is no longer there.
What I want to happen is the word icon is above the picture.

Start by taking a look at How to Use Labels and The JavaDocs for `javax.swing.JLabel
Basically, you have a number of options.
You can use
JLabel label = new JLabel("This is an Icon", icon, JLabel.CENTER);
You can use
JLabel label = new JLabel();
label.setText("This is an icon");
label.setIcon(icon);
You can use
JLabel label = new JLabel("This is an icon");
label.setIcon(icon);
You can use
JLabel label = new JLabel(icon);
label.setText("This is an icon");
To centre the text over the image you could use something like...
label.setVerticalTextPosition(JLabel.TOP);
label.setHorizontalTextPosition(JLabel.CENTER);

You will want to check the JLabel API for there you'll find the correct constructor, one with an Icon, a String and an int for horizontal alignment:
public JLabel(String text,
Icon icon,
int horizontalAlignment)
horizontalAlignment - One of the following constants defined in SwingConstants: LEFT, CENTER, RIGHT, LEADING or TRAILING.

Another way to show images in JLabel, is to use HTML:
String imageInHtml = "<html> Image 1 </br> <img src = \"/absolute/path/to/file.jpg\" height = \"120\" width =\"50\"/> </html>";
JLabel l = new JLabel(imageInHtml);
this way you an also show easily multiple images with one label.
PS:
This also works with images which are in a jar on the classpath.
