Java - Set width/height of JLabel

Question

I am adding an image into a JLabel and trying to set the width and height... but it's not working... help?

as you can see here... the tiles are not 32 by 32...

code:

import java.applet.Applet;

public class LayoutExample extends JApplet {

    Label msgL = new Label("Messages");
    Label statusL = new Label("Status");
    Label inventoryTitleL = new Label("Your Inventory");
    Label idL = new Label("Name, Stats");
    Label messageInL = new Label("read message here");
    Label messageOutL = new Label("type message here");

Answer 1

There are numerous problems with the posted code:

a) Don't use AWT components in a Swing Application. All components used should start with "J" (ie. JLabel, JTextArea, JTextField)

b) The code you have posted was copied from an old AWT Applet. Swing Applets are coded differently. Start by reading the section from the Swing tutorial on How to Make Applets for a basic example. For example you should NEVER override the update() or paint() methods in a JApplet or JFrame or JDialog.

c) There is no need to set the size of a JLabel. The label will automatically be the size of the Icon added to it.

Clean up your code and then post a SSCCE (http://sscce.org) if you still have problems. I'm not about to look through a hundred lines of code to figure out where you read the image and add it to a label.

Answer 2

Normally, you can call label.setMinimumSize(new Dimension(width, height)) to make something be forced at a size. Not sure exactly what you're trying to do here - your SSCCE isn't all that short.
