Good afternoon,
I'm using Scout 6 in the neon eclipse.
I have the following problem, I need to create in the menu bar of the desktop an avatar that can be changed by the image that is saved in the database.
The abstractMenu does not allow to insert image, only icons already registered. Is there any way to load an image into a menu without being an icon?

Hi Juliano

I did not try it, but it seems to be possible by using special iconIds that are handled by your own IIconProviderService. Have a look at this code:
https://github.com/BSI-Business-Systems-Integration-AG/org.eclipse.scout.docs/blob/releases/6.0.x/code/bahbah/org.eclipsescout.demo.bahbah.client/src/main/java/org/eclipsescout/demo/bahbah/client/services/BuddyAvatarIconProviderService.java

Regards,
Beat

Hi,
In my Scout application I would like to do a very similar thing: present in the desktop menu, dynamically determined avatar from a graphic file downloaded ad-hock from the Internet. I referred to the above-mentioned example BuddyAvatarIconProviderService.java, but I have the following problem with it. During desktop initialization, the icon content (using the loadLocalAvatarIconSpec method) is downloaded twice by a web browser:

Initial POST request, where in the above-mentioned loadLocalAvatarIconSpec method, the ClientSession.get() call returns the session object, and thus further download of the image content is done correctly.
Second GET method, where in the above-mentioned loadLocalAvatarIconSpec method, the ClientSession.get () call returns NULL, and thus the icon content cannot be read (in the session object I store information necessary to download the icon). This finally results in the avatar not being displayed in the menu.

My question:
Why does the ClientSession.get() method return NULL while handling this second GET request?
How to solve this problem?

Hi Krzysztof

I overlooked your question, because it was in an old thread. In newer Scout releases this is quite simple. Use an AbstractFormFieldMenu and place an AbstractImageField in the menu, which simply points to the URL of the image. Example code:

@ClassId("ee078d57-7f35-4f8e-9cc8-0e243a4965fe")
public class GraphicalMenu extends AbstractFormFieldMenu {

	@ClassId("e01405aa-4465-42c7-84d5-0068f33142a9")
	public class Image extends AbstractImageField {

		@Override
		protected void execInitField() {
			setImageUrl("https://img.icons8.com/color/2x/bmo.png");
		}
	}
}

See the attached image-menu.jpg for a preview.

Cheers,
André

Hi André,

Your solution did not work for me. No image is displayed in the menu.
Maybe because on your attachment "image-menu.jpg" I see, that you have placed the GraphicalMenu declaration in the table/form node menu, and as I wrote earlier, I need to display the image in the desktop main menu.
