У меня есть простой маленький чат-клиент, я обновляю несколько компонентов графического интерфейса из потока, когда java-клиент получает новое сообщение с сервера.
Вот ветка:
/*
* Thread class to listen for message from the server
*/
class ListenFromServer extends Thread {
public void run() {
BufferedReader in = new BufferedReader(new InputStreamReader(is));
while (true) {
try {
String tmpMsg = in .readLine().replaceAll("\\r\\n|\\r|\\n", "");
JSONObject json = new JSONObject(tmpMsg);
updateInfo(x,x,x,x,x,x,x,x,x); // Just to show
printMsg("hello world", "server", "21:20"); // prints message to JTextPane
}
} catch (Exception e) {
e.printStackTrace();
}
}
}
}
Поэтому, когда сообщение получено, я запускаю следующие две функции:
public void updateVisitorInfo(final String userCountry, final String userCity, final String visits, final String seType, final String seKeyword, final String trafficType, final String currentPage) {
SwingUtilities.invokeLater(
new Runnable() {
public void run() {
System.out.println("UPDATE");
jLabel23.setText(userCountry + ", " + userCity);
int numberOfVisits = Integer.parseInt(visits);
if (numberOfVisits <= 1) {
jLabel33.setText("<html>First visit</html>");
} else {
jLabel33.setText("<html>Returning visit:<br><b>" + visits + "</b> visits</html>");
}
if (trafficType.contains("Direct")) {
jLabel43.setText("<html>Came from: Direct hit</html>");
} else if (trafficType.contains("Organisk")) {
jLabel43.setText("<html>Came from: " + seType + "<br />Searched keyword:<br /><b>" + seKeyword + "</b></html>");
} else if (trafficType.contains("AdWords")) {
jLabel43.setText("<html>Came from: AdWords<br />Searched keyword:<br /><b>" + seKeyword + "</b></html>");
}
jLabel53.setText("<html><div style='width:140px;'><p>Current:<br /> <a href='" + Page + "'>" + currentPage + "</a></p></div></html>");
}
});
//jLabel83.setText("<html><div style='padding-left:50px;'>Chat with " + visitorNick + "</div></html>");
}
а также:
public void printMsg(final String msg, final String from, final String tid) {
SwingUtilities.invokeLater(new Runnable() {
public void run() {
if (msg != null && !msg.isEmpty()) {
String align = "text-align:right;";
String padd = "padding-left:12px;";
if (from.contains(agentName)) {
align = "text-align:right;";
padd = "padding-right:12px;";
} else {
align = "text-align:left;";
padd = "padding-left:12px;";
}
// Print the message
try {
kit.insertHTML(doc, doc.getLength(), "<div id=\"\" style=\"padding-top:10px;padding-bottom:10px;" + padd + "\">" + "<div id=\"\" style=\"position:relative;" + align + "\"><span style=\"color:#111111;font-weight:bold;\">" + from + "</span> at " + tid + ":</div>" + "<div id=\"\" style=\"padding-top:4px;" + align + "\">" + msg + "</div>" + "</div>", 0, 0, null);
} catch (BadLocationException ex) {
Logger.getLogger(Client.class.getName()).log(Level.SEVERE, null, ex);
} catch (IOException ex) {
Logger.getLogger(Client.class.getName()).log(Level.SEVERE, null, ex);
}
ta.setCaretPosition(ta.getDocument().getLength()); // To scroll to the bottom of the JTextPane
}
}
});
РЕДАКТИРОВАТЬ: JPanels, содержащие компоненты из приведенного выше кода, становятся белыми, поэтому все приложение не зависает, но JPanels становится белым
РЕДАКТИРОВАТЬ 2:
Вот как я начинаю тему:
new ListenFromServer().start();
Этот код выполняется при загрузке JFrame (в пределах init())

Любые идеи, что я делаю неправильно здесь?
ListenFromServerв рабочий поток и из этого рабочего потока вызвал бы мои две функции? 09.09.2013
