Hi, everybody,
I wanted to implemented that a JButton in a JFrame, And when I click which button, a picture will be displayed on the JFrame. But how can I enable the size of the JFrame be changed into a suitable size ? And this is also my problem.

You use setSize(width, height) to change the size of a JFrame. How are you getting/storing the image? The Image class has getHeight() and getWidth() methods.

hello,

when the Component that displays your image automatically has the correct preferred size, you can use JFrame#pack().

Thanks so much for your replyes. But I do not think that setSize() and pack() can do what I wanted to do. I used this to show my pic.


Although the pic can be add into JFrame, but the size of JFrame still can not be changed.

Hmm, I tried changing your code and making it change the size of the parent component as well, but that didn't work either. Now I'm kind of stuck too
