How can I display an image (jpg) on a scrollable frame?

[frag]

Hi it's me again!

Here is my second problem:
I want to display a jpg-file on a scrollable frame/window.
I have no idea where to start! I don't even know how to open an image (i can only open text-files)!! :-I

Oh.. by the way... does anyone know how to set a filefilter for jpg-files in a JFileChooser?

thanx a lot!

Try java.awt.ScrollPane or java.swing.JScrollPane.

There's flashing problems though for very large images which I think you have to solve by extending the class and overriding update() or something to that effect.

For the jpg filechoose thing check in the api and use the files they provide for it. (they have done is already);
For getting image look at toolKit and getImage().

For scrollpane look at JScrollPane and a JPanel to it you must set the preffered size of the panel to be the size of image so that the scroll bars come up.

Chris good luck ( I know how you feel)

Hi, this is frag again!

Sorry boys, I am just too stupid for this!
I know that I need a JScrollPane and a JViewport but I don't know how to handle this stuff.
The example given on java.sun.com is too hard (I don't want to have a ruler!) and I can't change it to an easier one.
All I want is to display an image on a scroable frame!

Could please somebody trop me some lines of code?!?

Very thankful

frag,

> I finaly did it on my own (after 3 hours of research)!

Yup, that's the way it is supposed to work. None of us was born knowing how to do any of this stuff. If we know, it's because we did the 3 hours of research to learn it.
