我想知道如何将图像添加到MessageDialog框。我尝试了下面的代码,图像无处可寻。
I'm wondering How To Add Image To MessageDialog Box. I tried the code below and the image was nowhere to be found
else if(button == B){
String text = "blahblahblahblahblah";
JTextArea textArea = new JTextArea(text);
textArea.setColumns(30);
textArea.setLineWrap( true );
textArea.setWrapStyleWord( true );
textArea.setSize(textArea.getPreferredSize().width, 1);
Font font = new Font("Verdana", Font.BOLD, 12);
textArea.setFont(font);
textArea.setForeground(Color.BLUE);
JOptionPane.showMessageDialog(
null, textArea, "Border States", JOptionPane.PLAIN_MESSAGE);
image2 = new ImageIcon(getClass().getResource("borderstates.jpg"));
label2 = new JLabel(image2);
add(label2);

你的第一个停靠点应该是和,具体的
Your first port of call should be the Java API Docs and the Java Trails, specific How to use Dialogs
public class TestOptionPane04 {
public static void main(String[] args) {
EventQueue.invokeLater(new Runnable() {
@Override
public void run() {
try {
UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
} catch (ClassNotFoundException | InstantiationException | IllegalAccessException | UnsupportedLookAndFeelException ex) {
}
ImageIcon icon = new ImageIcon(TestOptionPane04.class.getResource("/earth.png"));
JOptionPane.showMessageDialog(
null,
"Hello world",
"Hello", JOptionPane.INFORMATION_MESSAGE,
icon);
JOptionPane.showMessageDialog(
null,
new JLabel("Hello world", icon, JLabel.LEFT),
"Hello", JOptionPane.INFORMATION_MESSAGE);
}
});
}
}
