Re: Dynamic image as table background

Thanks Geoff for your idea.
I can use CSS but my image come from a database and is map as a NSData. 

How can I get the dynamic URL from this ?

  I can't supply any code, just an idea, but couldn't you use CSS here? Put a style definition in your component and feed the image path into that? (this will mean putting the image under the webserver somewhere...)

    Hello list,

    Is there a way to serve a dynamic image as table background ?

    I have try to use a WOGenericContainer as Table  where imageBackground
    method  returns NSData of the image.

    GenericContainer1: WOGenericContainer { 
    background = imageBackground ;
    border = 1;
    cellpadding = 0;
    cellspacing = 0;
    elementName = "TABLE";
    height = hauteurTableau;
    width = largeurTableau;
    }

    Without success, as  I get the following trace :
