swing - Update Label text while button click action executing (Java) -


i have button , label on jframe. clicking on button try connect linux server , takes few second. want set label text connecting.. , connected.but doesn't set label text connecting .. during button operation executing. idea how that

private void buttonlconnectactionperformed(java.awt.event.actionevent evt) {     labellout.settext("connecting");     string ip="";     string userid="username";     string password="password"; main_window.lboxconnect=new sshconnection(ip,userid,password);     int x=lboxconnect.checkconnection();     if(x==1){     labellout.settext("connected");     if(dx==1)         buttonbttinsert.setenabled(true);     else         lx=1;     }     else     labellout.settext("connection failed"); }

you should long actions in background thread, not in button listener, otherwise ui seem frozen.

in listener, set text "connecting" , launch thread wrapping connection stuff. @ end of runnable, update text again once long operation has finished.
