Problem with layout manager

[mDennis10]

I have been having this problem for quit a while which has force me to use the setBounds method. Whenever i use a layout manager sometime or most times the components are not displayed on screen. What is causing this?

	//MSMsys Constructor
	public MSMsys ()
	{
		setTitle ("Management System \tMSMsys");
		setVisible (true);
		setSize (500,400);
		setDefaultCloseOperation (EXIT_ON_CLOSE);
		setLocation (300,200);
		setLayout (new FlowLayout ());
		
		setMenuBar ();
		setUserLogInPanel ();
	}//end constructor
	
//Displays logInPanel with login components
	public void setUserLogInPanel ()
	{
		//Create Components
		JLabel userNameLabel = new JLabel ("User Name: ");
		JLabel passwordLabel = new JLabel ("Password: ");
		JPanel logInPane = new JPanel ();
		
		logInPane.setBorder(BorderFactory.createTitledBorder ("User Login"));
		
		logInPane.setLayout (null);
		
		//Initialize instance variables 
		userNameTF = new JTextField (10);
		passwordTF = new JPasswordField (10);
		logInButt = new JButton ("Login");
		
		add(logInPane);
		logInPane.add(logInButt);
		
		//logInPane.setBounds (50,20,280,200);
		//logInButt.setBounds (50,20,30,30);
		logInButt.addActionListener (new EventHandler ());
		
	}//logInPanel

Well obviously the answer to your problem is

You're not using the layout managers correctly.

sorry about that

I see that you've edited your post and now have added some code, but your code won't compile nor run for us. We don't want or need the whole program but it would be helpful for you post a small compilable runnable program that demonstrates your problem, an SSCCE. Also, read the layout manager tutorials thoroughly before using them as well as the api, and you'll see that you shouldn't be using setSize or setBounds on anything. Also, please inform us of any and all places where you've cross-posted this question. Not doing so is bad forum etiquette as we may be wasting time answering a question that has already been answered.

I'm no swing expert but you might want to move the call to setVisible to be the last line.

Indeed, and call pack() before calling setVisible(true).
