  1. POCombbox action listener to show and hide an image
    text
    copied!<p>I've created a combobox with two options: Hide and Show inside a JPanel. I want to know how I can write an action listener, so when I select "Show" from the drop-down, a picture appears next to the combobox, and hides it when "Hide" is select. Many thanks in advance. Following is what I've got so far.</p> <pre><code>myPanel = new javax.swing.JPanel(); myLabel = new javax.swing.JLabel(); myComboBox = new javax.swing.JComboBox(); setDefaultCloseOperation(javax.swing.WindowConstants.EXIT_ON_CLOSE); myLabel.setText("myLabel:"); myComboBox.setModel(new javax.swing.DefaultComboBoxModel(new String[] { "Hide", "Show" })); javax.swing.GroupLayout myPanelLayout = new javax.swing.GroupLayout(myPanel); myPanel.setLayout(myPanelLayout); myPanelLayout.setHorizontalGroup( myPanelLayout.createParallelGroup(javax.swing.GroupLayout.Alignment.LEADING) .addGroup(myPanelLayout.createSequentialGroup() .addGap(28, 28, 28) .addComponent(myLabel) .addPreferredGap(javax.swing.LayoutStyle.ComponentPlacement.RELATED) .addComponent(myComboBox, javax.swing.GroupLayout.PREFERRED_SIZE, javax.swing.GroupLayout.DEFAULT_SIZE, javax.swing.GroupLayout.PREFERRED_SIZE) .addGap(237, 237, 237)) ); myPanelLayout.setVerticalGroup( myPanelLayout.createParallelGroup(javax.swing.GroupLayout.Alignment.LEADING) .addGroup(myPanelLayout.createSequentialGroup() .addGap(44, 44, 44) .addGroup(myPanelLayout.createParallelGroup(javax.swing.GroupLayout.Alignment.BASELINE) .addComponent(myLabel) .addComponent(myComboBox, javax.swing.GroupLayout.PREFERRED_SIZE, javax.swing.GroupLayout.DEFAULT_SIZE, javax.swing.GroupLayout.PREFERRED_SIZE)) .addContainerGap(36, Short.MAX_VALUE)) ); </code></pre>
