Hello All.

Does anybody knows how can i download an image from internet with
SWT(Image)?????

I´m doing a program that connects with a movie's page, and i want to
download the cover for the movie that user selects...
I´m searching in Google, but i don´t find...
I´m creating Url objetc, inputstream, but i don´t know to do that!!
If someone gives me a url with a snippet, or post here, will be apreciated.

Thansk, and excuse for my bad english...

Here's a simplified snippet:

try {
URL url = new URL("http://www.google.com/intl/en/images/logo.gif");
InputStream is = url.openStream();
Image image = new Image(Display.getCurrent(), is);
}
catch (Exception e)
{
e.printStackTrace();
}
finally
{
is.close();
}

Hope this helps.
- Jeff

Thanks... i will probe this little snippet..Yesterday i was probing a
snippet that i don´t know how, but functions...
------------------------------------------------------------ -----------
private void retrieveImage(String direccionImagen) {

ImageData[] imageDataArray,imageDataArray1;
URL url = null;
try {
url = new URL(direccionImagen);
} catch (MalformedURLException e) {

e.printStackTrace();
}
InputStream stream = null;
String urlfile=url.getFile();

NombreFichero nom=new NombreFichero(urlfile,'/');
// here i parse urlfile to obtain name and extension to save
// after...

try {
stream = url.openStream();
} catch (IOException e) {

e.printStackTrace();
}
ImageLoader loader = new ImageLoader();

imageDataArray = loader.load(stream);
String
pathCompleto=ProgramData.programImagesDir+System.getProperty ( "file.separator")+nom.nombreCompleto();
loader.save(pathCompleto,SWT.IMAGE_JPEG);

try {
stream.close();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

int imageDataIndex = 0;
Image image = new Image(GUI.display, imageDataArray[imageDataIndex]);
