    text
    copied!<p>I have created a basic swing program which displays an image in a <code>JDialog</code> box after it has been selected through a <code>JFileChooser</code>. I have used a <code>JScrollPane</code> inside the dialog box and a <code>JLabel</code> on which image is added as an icon, inside the pane.</p> <p>The following is the code I have used to construct the dialog box and its contents, the objects are already initialized with a simple new call:</p> <pre><code> jDialog1.setTitle("Image"); jDialog1.setModal(true); jLabel1.setHorizontalAlignment(javax.swing.SwingConstants.CENTER); jScrollPane2.setViewportView(jLabel1); </code></pre> <p>Netbeans has been used to build the GUI. </p> <p>The following is the code I have used to load and display the image:</p> <pre><code> int rval = jFileChooser1.showDialog(this, "Show"); File f = jFileChooser1.getSelectedFile(); jDialog1.setTitle(jDialog1.getTitle() + " : " + f.getName()); try { BufferedImage bf = ImageIO.read(f); jLabel1.setIcon(new ImageIcon(bf)); } catch (IOException ioe) { } jDialog1.setLocationRelativeTo(null); jDialog1.setVisible(true); jDialog1.pack(); </code></pre> <p>Though the image is loaded and displayed, the trouble is</p> <ul> <li><p>My dialog box appears in a minimized form in the upper left hand corner and i have to drag its corner to view the image. Including an image of the same.</p> <p><img src="https://i.stack.imgur.com/LLTn9.jpg" alt="enter image description here"></p></li> <li><p>The horizontal scroll of the scroll pane disappears long before the dialog box is fully extended and the image is fully displayed. Though the vertical scroll bar acts fine.</p></li> </ul> <p>I have tried setting size and preferred size of both <code>JDialog</code> and <code>JLabel</code> but the problems still persist.</p> <p>Thanx in advance!</p> <p><strong>Note:</strong> The horizontal scroll bar problem is solved by using the <code>pack()</code> method on the dialog box but the minimized dialog box is still there. Also, the dialog box now appears in the center of the screen as well.</p>
