我只想爲ComboBox設置自定義列表模型。評論的代碼也沒有奏效。我完全不知道爲什麼!在intellij中自定義組件創建失敗
我在的IntelliJ社區版工作JDK 1.8
import jssc.SerialPortList;
import javax.swing.*;
import java.awt.*;
public class sampleForm extends JFrame {
private JComboBox comboBox1;
private JPanel panel1;
/*public sampleForm() {
super("title");
String[] portNames = SerialPortList.getPortNames();
setLayout(new FlowLayout());
comboBox1 = new JComboBox(portNames);
add(comboBox1);
}*/
public static void main(String[] args) {
JFrame frame = new JFrame("sampleForm");
frame.setContentPane(new sampleForm().panel1);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.pack();
frame.setVisible(true);
}
private void createUIComponents() {
// TODO: place custom component creation code here
String[] portNames = SerialPortList.getPortNames();
comboBox1 = new JComboBox(port);
}
}
