Java programmers look inside!

[Slimfast]

Hi, for the programming course at school I need to figure out how to display a jpg image in java in an application, not applet, at the end of a game that I wrote. Can anyone help me out? thanks!

[mprielozny]

not applet,

can you at least use swing?

[Slimfast]

i'm ******** at swing....(I can only do really basic level programming) but can you post some demo code? the stuff i find on google won't compile..maybe i'm doing something wrong. I'm using ConTEXT and compiling stuff through there.

especially look for something like

jPanel1 = new JPanel();
jPanel1.setBorder(new javax.swing.border.EtchedBorder());
jPanel1.setBounds(408, 164, 160, 170);
getContentPane().add(jPanel1);

jLabel1 = new JLabel(new ImageIcon("resources/legend.png"));//new ImageIcon("resources/icon_thing.gif").getImage());
jLabel1.setBounds(0, 0, 200, 200);
jLabel1.setVisible(true);
jPanel1.add(jLabel1);

[Slimfast]

I need all that to display one lousy picture? yowch

[mprielozny]

definately not

tihs is enough

jPanel1 = new JPanel();
jPanel1.setBorder(new javax.swing.border.EtchedBorder());
jPanel1.setBounds(408, 164, 160, 170);
getContentPane().add(jPanel1);

jLabel1 = new JLabel(new ImageIcon("resources/legend.png"));//new ImageIcon("resources/icon_thing.gif").getImage());
jLabel1.setBounds(0, 0, 200, 200);
jLabel1.setVisible(true);
jPanel1.add(jLabel1);

Damn, that's still close to a dozen lines to display a pic!

[fwhc022883]

Damn, that's still close to a dozen lines to display a pic!

Some of those lines are just for visual enhancements such as the setBorder and the setBounds method. I just squeeze it into 4 lines.

[Slimfast]

i got it working! Thanks a lot guys!

[deep]

definately not

tihs is enough

jPanel1 = new JPanel();
jPanel1.setBorder(new javax.swing.border.EtchedBorder());
jPanel1.setBounds(408, 164, 160, 170);
getContentPane().add(jPanel1);

jLabel1 = new JLabel(new ImageIcon("resources/legend.png"));//new ImageIcon("resources/icon_thing.gif").getImage());
jLabel1.setBounds(0, 0, 200, 200);
jLabel1.setVisible(true);
jPanel1.add(jLabel1);

Java seems so efficient suddenly.

[mprielozny]

Damn, that's still close to a dozen lines to display a pic!

well you can go this

getContentPane().add(new JLabel(new ImageIcon("resources/legend.png")));


and i guess you never used any of the real programming languages like 10-15 years ago when displaying JPG took close to 2000 lines.

now they make it too easy for newbies they dont appriciate how easy they have it.

Thats how java is. If you want to do this stuff with less code, choose a different language, that or find some java libraries that will make it easier.
