How do I put a picture in my gui?

HI there,

you can put a picture in your GUI by Using a JLabel

JLabel bg = new JLabel(new ImageIcon("test.jpg"));

then by using XYLayout you can specify the size

myFrame.getContentPane.setLayout(new XYLayout());

myFrame.getContentPane.add(bg,new XYConstrain(0,0,800,600));

the previous code shows the Picture (test.jpg) as a JLabel and it's put at the background (imagin that your frame size is(800,600))

then the XYConstrain helps you specify the location and the size

(int,int,int,int)

these are for :

1 - y location

2 - x location

3 - width (size)

4- height (size)

note : the picture should be put in the same class file.

good luck

Well, thats what you get for copying code rather than taking the time to read the tutorial an understand what is going on.

XYLayout is not a standard JDK class. It comes with a GUI builder, which is why the code shouldn't be used. Its not portable.

How about this.....can anyone please tell me how to put some buttons on the top of the gui instead of all of them in one row? Also I have code for an image but it changed the java cup, instead of inserting it somewhere in the gui window.

any help would be much appreciated!!!

Someone used my code before I added this new stuff. They took it word for word.

I apologize if you are getting frustrated with me. Please know I am working very hard on this. Learning Java in just a few weeks to me is impossible so I wil take all the help i can get. I know it must seem very easy to you because you know it very well but I am just learning, maybe you can remember back to when you were learning?

Anyways i tried this code but it did not work. I didn't get any errors when compiling but nothing showed.:

JLabel label = new JLabel ( new ImageIcon("test.gif"));

f.getContentPane().add(label, BorderLayout.NORTH);

Here is my code but please keep in mind that alot of it has comments because I have not actually worked on the code for it yet. Just getting the buttons set up is where I am at.

I really wish that i could look at the examples and just have it be easy to code from it. I tried and I tried and sometimes I can get it but sometimes I just can't.

Thank you,

If it is to hard for you then change careers. Just please stop whining about how hard it was for you. When I learned it I never used my ignorance as an excuse.

It does work. Please, please, please read the linke posted about an SSCCE program!

I am not a java programmer. It is a required class to get an IT degree. My speciality is not Java, I use unix everyday but not Java.

I'm a full time working mother of 4. And I'm not exaggerating when I say it's very hard to attend school but I'm toughing it out.

I really am trying my best.

Last time I was told that I posted two liines of code, i posted the rest of my code and then was told why did I post all my code.....

Please if you don't want to help me, I really do understand. But then don't post to my question please. I'm sure there are others who remember or know what it's like to experience what I am and are willing to help me. All your negativity is just discouraging me and I need all the encouragement I can get.

And I did eventually figure it out.

thank you.

Because Java is so foreign to me I did not know I could just send you bits of my code enough for you to compile. My mistake. That is not something I knew.

I appreciate your advice and obviously you were very irritated that I could not comprehend your adivce so easily. I was not at all ignoring any of the posts...I always try to best to understand it.

And my last comment, well each of your posts have been negative and mean. Sorry but its just how I read them and it was just very discouraging.

thank you for your time.
