Theming question: How to get rid of gradient background image

[panyasan]

Hello,

I am trying to get rid of the stylish gradient background image in the
toolbar and table headers which looks good in principle but gets old really
fast a complex UI with many toolbars and tables. I have experimented with
overriding entries in the Appeareance and Decoration classes in the "theme"
folder of my app, but haven't been successful.

Is there an easy way of replacing the gradient image with a plain color
background? Maybe someone has already done that.

Thanks,

Christian

Hello Christian,


overriding entries in your application's theme is the correct way to go. :-)

What have you tried so far? You can remove a decorator by setting the value
to undefined:

qx.Theme.define("helloworld.theme.Appearance",
{
  extend : qx.theme.modern.Appearance,

  appearances :
  {

    "table-scroller/header":
    {
      style : function(states)
      {
        return {
          decorator : undefined
        };
      }
    }
   
  }
});


Kind regards
Jonathan

Does undefined work? I would have thought null would be a better option?

Hello Matthew,


yes, null would als work, as we do a simple check like "if (decorator)  ...
{} ". But we decided to use undefined anywhere in the qx.theme namespace, so
it would be convenient to stay with it. ;-)

Cheers
Jonathan
