How to add 'binaries' to Galleria using Jakarta 10 & Faces 4.0?

[NOTiFY]

Using: GraphicImage I could add a single binary image by:

Code: Select all

public InputStream getGraphicImage() throws IOException {

   ...
   
   return Files.newInputStream(Paths.get(stringBuffer.toString()));
}

Code: Select all

<p:graphicImage value="#{nOTiFYMotorcycleController.graphicImage}" stream="false"/>

I can't see how to add a "InputStream/byte[] array)" in "Galleria - Basic". I want to display a number of "Images" within a <List>?

The Doc doesn't show a 'binary' in: https://primefaces.github.io/primefaces ... s/galleria

TIA

if you combine this:
https://primefaces.github.io/primefaces ... collection

and

https://primefaces.github.io/primefaces ... ce-request

it should work (didnt try and no time to create a example)

The PF demo of Galleria shows using "galleriaView.photos":

Code: Select all

<p:galleria value="#{galleriaView.photos}" var="photo" numVisible="5" style="max-width: 640px">

In a Array List:

Code: Select all

private List<Photo> photos;

The "photo`' is just a Strings for "Galleria":

Code: Select all

private String itemImageSrc;
private String thumbnailImageSrc;
private String alt;
private String title;

To add "InputStream/byte[] array)" to "Galleria - Basic" I believe I really need something like:

Code: Select all

private InputStream itemImageSrc;
private InputStream thumbnailImageSrc;
private String alt;
private String title;

Added to an "ArrayList".

The two examples you've posted, I don't understand how to add a <List> of 'x' "p:galleria" (byte). Have you a demo of the "Dynamic Collection" -"galleriaBean.images"

[tandraschko]

you have to understand what happens in my second link, thats the key.
In general you should completely read the whole page to understand: https://primefaces.github.io/primefaces ... miccontent
everything is explained there, why your apporach doesnt work.

Where/How do I store/add the URLs of the Images or the Image as a InputStream/StreamedContent?

Where in 'Galleria' hardcoded demo has a number of Images in a ArrayList.

IMO - I find the PF Documentation re GraphicImage/Galleria a little too terse for me. TIA.

if you read my links carefully, you should be able to combine it. You can also check it: https://stackoverflow.com/questions/804 ... pdatatable
Doenst matter if ui:repeat and p:galleria

we just dont have enough time to create a example for everything. feel free to help to improve our samples or docs.

Doesn't matter if ui:repeat and p:galleria

Still confused.

Should/Can I use "ui:repeat" or with JSF 4.0 "<c:forEach>" with "p:galleria" ?

The example you referenced: https://stackoverflow.com/questions/804 ... pdatatable

Does't use "p:galleria" it has:

Code: Select all

private List<StreamedContent> allImages = new ArrayList <>();

So can I create my 1-999 'Images' be added to a 'List' and display them with <u:report> (<c:forEach>):

Code: Select all

<ui:repeat value="#{ImageLoader.allImages}" var="img"> 

When worked i'm happy to provide: "feel free to help to improve our samples or docs.".

check the answer in stackoverflow, not the question.

[NOTiFY]

Had a good look at "check the answer in stackoverflow, not the question" for:

https://stackoverflow.com/questions/804 ... pdatatable

JSF:

Code: Select all

<ui:repeat value="#{bean.images}" var="imageID">
    <p:graphicImage value="#{bean.image}">
         <f:param name="imageID" value="#{imageID}" />
    </p:graphicImage>
 </ui:repeat>

Managed Bean:

Code: Select all

public List<String> getImages() {
    List<String> l = new ArrayList<String>();
    for (Theme t : themeFacade.findAll())
        l.add(t.getId().toString());
    return l;
}

Code: Select all

public StreamedContent getImage() {
      FacesContext context = FacesContext.getCurrentInstance();
      HttpServletRequest myRequest = (HttpServletRequest) context.getExternalContext().getRequest();
      String imageID = (String) myRequest.getParameter("imageID");
      return new DefaultStreamedContent(new ByteArrayInputStream(themeFacade.find(Long.parseLong(imageID)).getImage()));
}

Do you know/suggest what "Theme (themeFacade)" should be?:

Code: Select all

Theme t:themeFacade

it should work (didnt try and no time to create a example)

Any chance of a simple sample that shows a "List" of 'images' on "Galleria"? TIA

"is EXACTLY your case but i had some minutes and ported this example to the primefaces showcase.... github.com/primefaces/primefaces/issues/9948 and no, i can't deploy it, that's up to primetek"

Thanks.
