    <p>I'm relatively new to GUI building.</p> <p>I want to make a GUI with a button(that I already have) that a user can press and select an image and then dynamically, this image to be loaded in the GUI in a panel. I want the image to change dynamically every time the user browses an image.</p> <p>So far my code is that .... But I cant connect the button to a JPanel or something.</p> <pre><code>import java.awt.Graphics2D; import java.awt.RenderingHints; import java.awt.image.BufferedImage; import java.io.File; import javax.swing.*; public class WebAppImg extends javax.swing.JFrame { private int image_height; private int image_aspect_ratio; private Graphics2D engine; private JLabel photoComponent; /** * Creates new form WebAppImg */ public WebAppImg() { initComponents(); } /** * This method is called from within the constructor to initialize the form. * WARNING: Do NOT modify this code.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
