setVisible appears to be jamming screen
I am currently having a problem where I open a new window in a separate class to display a game board. When the window is opened however none of the components show despite setVisible(true) being called. In this class a nework server is also being set up, which could be causing the jam. Although this class runs fine when not loaded from the previous class.
Sorry this is probably not the best explanation ever, here is the code where the new window is called in the initial class:
if (cmd.equals("create")) {
NetServer host = new NetServer();
frame1.setVisible(false);
}
NB: Create is simple an action command
Here is the code for the called class:
Constructor:public NetServer() {
setJMenuBar(menuBar);
setLayout(new BorderLayout());
addWidgets();
add(board, BorderLayout.CENTER);
setDefaultCloseOperation(EXIT_ON_CLOSE);
setTitle("Atomz Server Player");
setSize(400,400);
SwingUtilities.invokeAndWait(this.setVisible(true));
netServ();
}
netServ() method:
public void netServ() {
String lostcon = "";
try {
ServerSocket s = new ServerSocket(3000);
while (true) {
Socket incoming = s.accept();
BufferedReader in = new BufferedReader(new InputStreamReader(incoming.getInputStream()));
PrintWriter out = new PrintWriter(new OutputStreamWriter(incoming.getOutputStream()));
while (true) {
if(!ClientGo){//SERVERS GO
if(ServerTrigger){
out.println(ServerMove);
out.flush();
ClientGo = true;
ServerTrigger = false;
}
}
out.flush();
if(ClientGo){//CLIENTS GO
String str = in.readLine();
System.out.println(str);
int actx, acty;
String act = new String();
for(int i=0;i<gridx;i++) {
for (int j=0;j<gridy;j++) {
actx = i;
acty = j;
act = String.valueOf(i) + String.valueOf(j);
if (str.equals(act)) {
String atoms = play[j].getLabel();
if (gplayer.equals("red")) {if(play[j].getBackground()!=Color.blue){ // check if legal move
addAtom(actx, acty, atoms, gplayer);// red player
gplayer = "blue";
sysmessage.setText("Blue Player's Turn");
out.flush();
} // end legal check
}
}
}
}
if(str == null){
lostcon = null;// test for null
}
ClientGo = false;
gplayer = "blue";
out.flush();
}
if (lostcon == null) {
incoming.close();
// null = lost connection
break; // client closed connection
}
}
incoming.close();
s.close();
}
} catch (Exception e) {}
}
Add widgets simply adds components to board.
A connection is still detected even when none of the swing components show.
I would be very greatful for any help!!>
