null-layout-manager

Few months ago i read this Swing tutorial http://zetcode.com/tutorials/javaswingtutorial/resizablecomponent/ for understanding how implementing resizable components inside Swing. The tutorial tells about using a null LayoutManager in order to have the possibility of absolute positioning child components. In a discussion relative to another subject @Andrew Thompson pointed out that using null layout is a bad idea. This article http://download.oracle.com/javase/tutorial/uiswing/layout/none.html describe null layout manager as not desirable too, anyway it says that in certain situations the might

I'm doing the following call in my code: ... setLayout(null); ... I'm trying to place a button and a textfield by specifying their x and y coordinates. The problem when I run the program (either with Eclipse or BlueJ) is that I need to run on the panel up to the position of the button and the textfield in order to see respectively the button and the textfield. When I find the textfield, it is small. Only when I start writing it assumes the size I specified. Does anyone know how to solve it? Avoid setLayout (null), unless you have a very good reason for it. You can learn about layout managers

I want to show many different labels over a map, so I'm using null layout in my panel, and calling setLocation for each label. For some reason, though, the labels don't show. If I remove the pan.setLayout(null), then the label appears in the top-center of the panel. Why isn't null layout working with setPosition? package mapa; import java.awt.*; import javax.swing.*; public class Mapa extends JFrame { private static JPanel pan; private static JLabel lab; public Mapa() { } private static void createAndShowGUI() { Mapa frame = new Mapa(); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); lab

I have all of the labels working correctly but the userLabel[3] is not positioning properly No matter what I do, the label "Color:" always shows up on the frame with a x-coordinate of 0 and a y-coordinate that is half way down the frame. JLabel[] userLabel = new JLabel[4]; for(int p = 0; p < userLabel.length; p++){ userLabel[p] = new JLabel(); userLabel[p].setSize(100,50); frameSetUp.add(userLabel[p]); } userLabel[0].setText("Width of Frame:"); userLabel[1].setText("Height of Frame:"); userLabel[2].setText("# OF Balls:"); userLabel[3].setText("Color:"); userLabel[0].setLocation(10,35);

I'm trying to place a series of JLabels at specific X and Y coordinates on a JPanel (and set its height and width, too). No matter what I do, each label winds up immediately to the right of the previous label and has the exact same size as all of the others. Right now, my Jpanel is in a Grid Layout. I've tried Absolute Layout (illegal argument exception results), Free Design (no labels appear), Flow Layout (everything just gets squeezed to the center), and a few others. Not sure what I need to do to make this work. Can anyone help? Thanks! JLabel lbl1 = new JLabel("label 1"); JLabel lbl2 = new
