path to images? [message #448952]

Hi,

Can anyone tell me what the path (for loading etc.) to any image files I
have in my plugin?

e.g. if I have a directory icons in my plugin project, what is the path to

icons/mypic.gif

?? I cannot get anything other than a hardcoded full path to work.

cheers
David

While the following solution is not the simplest, I prefer it to other
options. Create the following plug-in

public class MyPlugin extends AbstractUIPlugin {
private static MyPlugin instance;

public MyPlugin() {
MyPlugin.instance = this;
}

public static MyPlugin getDefault() {
return MyPlugin.instance;
}

public String getPluginId() {
return (this.getBundle().getSymbolicName());
}

public Image getImage(String path) {
Image img = this.getImageRegistry().get(path);

if (img == null) {
img = getImageDescriptor(path).createImage();
this.getImageRegistry().put(path, img);
}

return (img);
}

public ImageDescriptor getImageDescriptor(String path) {
ImageDescriptor desc =
AbstractUIPlugin.imageDescriptorFromPlugin(this.getPluginId( ), path);
return (desc == null? ImageDescriptor.getMissingImageDescriptor() : desc);
}
}

Now, in your code, you load images using the following code:

Image img = MyPlugin.getDefault().getImage("path/to/my/image.gif");

Images must be stored in your plug-in folder or in sub-folder. The added
benefit of this solution is that your plug-in manages loaded images and
you do not need to dispose() them. It also makes easy to load image
descriptors.
