Images from web in Eclipse [message #264588]

Hello there,

Currently I'm busy playing around with eclipse and there is a litle thing
that does not work yet. I have an image. (lets say
http://www.jvw.nl/images/eclipse.jpg ) and I want to show it in a eclipse
application. I read it from the web with an input stream but the image is
not shown. There are no errors reported whatsoever.

Does anyone know how to accomplish this?

Hello,

here is some code I use to create the image:

I've got an Object which generates an url string, creates an get method
for the apache httpclient and finally does the following:

InputStream in = getImage.getResponseBodyAsStream();
return this.loader.load(in)[0];

As you can see here I return the ImageData that was generated from the
InputStream. Tests with a filewriter object (plain old java) showed me
that the image that I write to the disk using this getresponsebodyasstream
was a valid image.

In the code that is using the return value I do the following:

ImageData data = this.gm.generateMap() // method wich returns the
imagedata shown above

Image img = new Image(this.map.getShell().getDisplay(),data);
this.map.setImage(img);

the this.map is a Label instance.
Even when I do a map.getShell.redraw the image is not shown.

When I set the image as background for the Label it does work now.
