    <p>I am currently developing an HTTP application using Apache's http API and I am using a GUI. After after every GET or POST request I want to update a GUI TextArea with some messages. The problem is that those messages appear after all the requests are done. </p> <p>I also noticed that if I write messages on the console after every request, the message appear, but if I write on the GUI all the messages appear on the end.</p> <p>Here is some code snippets:</p> <p>GUI constructor:</p> <pre><code>public GUI() { initComponents(); SetMessage.gui = this; } </code></pre> <p>SetMessage class:</p> <pre><code>public class SetMessage implements Runnable{ public static GUI gui; private String msg; public SetMessage( String msg){ synchronized(gui){ this.msg = msg; } } public void run() { gui.setText(msg); } } </code></pre> <p>The GET request class (every request is made by a thread):</p> <pre><code>public class SendGetReq extends Thread { private HttpConnection hc = null; private DefaultHttpClient httpclient = null; private HttpGet getreq = null; private int step = -1; private String returnString = null; public SendGetReq(HttpConnection hc, DefaultHttpClient httpclient, HttpGet getreq, int step) { this.hc = hc; this.httpclient = httpclient; this.getreq = getreq; this.step = step; } @Override public void run() { // CODE } </code></pre> <p>And HttpConnection Class (the instance of this class is created when I press a button on the GUI):</p> <pre><code> public class HttpConnection { private DefaultHttpClient httpclient = null; private HttpGet getreq = null; private HttpPost postreq = null; private SendGetReq tempGet = null; // More fields private void RandomMethod(){ //Initialize getreq (tempGet = new SendGetReq(this, httpclient, getreq, 0)).start(); new SetMessage("Message").run(); } </code></pre> <p>Oh! And the GUI's SetText method:</p> <pre><code>public synchronized void setText(String msg){ if(!"".equals(msg)){ Date currentDate = new Date(); Calendar calendar = GregorianCalendar.getInstance(); calendar.setTime(currentDate); jTextArea1.append(calendar.get(Calendar.HOUR_OF_DAY)+":"+calendar.get(Calendar.MINUTE)+":"+calendar.get(Calendar.SECOND)+" --- "+msg+"\n"); } } </code></pre> <p>Can anyone help me with this problem? Thanks! }</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
