Ho cercato molto su Google ma non ho trovato una risposta al mio problema. Come puoi vedere dall'immagine qui sotto, l'applicazione avviata in modalità debug da NetBeans rispetta le dimensioni che ho assegnato.
IMMAGINE 1
quando compilo il programma e avvio il JAR creato, le dimensioni sono maggiori. Voglio che le dimensioni del JFrame siano sempre quelle assegnate
IMMAGINE 2
ATTENZIONE, NELLA REALTA' L'IMMAGINE 2 E' QUASI IL DOPPIO DELLA 1
questa è la classe
public class MainFrame extends javax.swing.JFrame {
static Preferences sp;
/**
* Creates new form NewJFrame
*/
public MainFrame() {
initComponents();
sp = Preferences.userNodeForPackage(MainFrame.class);
URL whatismyip = null;
try {
whatismyip = new URL("http://checkip.amazonaws.com");
} catch (MalformedURLException ex) {
Logger.getLogger(MainFrame.class.getName()).log(Level.SEVERE, null, ex);
}
BufferedReader in = null;
try {
in = new BufferedReader(new InputStreamReader(
whatismyip.openStream()));
} catch (IOException ex) {
Logger.getLogger(MainFrame.class.getName()).log(Level.SEVERE, null, ex);
}
String ip = null;
try {
ip = in.readLine(); //you get the IP as a String
} catch (IOException ex) {
Logger.getLogger(MainFrame.class.getName()).log(Level.SEVERE, null, ex);
}
if (sp.get("ip", "").equals("")) {
sp.put("ip", ip);
}
if (sp.get("ip", "").equals(ip)) {
jLabel5.setText("Non cambiato");
jLabel2.setText(ip);
jLabel4.setText(ip);
} else {
jLabel5.setText("Cambiato");
sp.put("ip", ip);
jLabel4.setText(ip);
}
}
