Theme customisation ("test-red") - setting background color of top part

[Tim Hoffman]

Hi

I am working through some theme customisation for itop 3.0.x

I am trying to chnage the background of "ibo-navigation-menu--top-part--background-color"

I have tried following https://www.itophub.io/wiki/page?id=3_0_0%3Acustomization%3Atheme#how_to_create_a_new_theme

I unable to user : the example for test theme "test-red"

The example indicates

<theme id="test-red" _delta="define"></theme>

Using _delta="define"  results in an error as I would expect as the theme already exists

""rct-login-custom-content": /theme[test-red] at line 17 could not be added : already exists in /itop_design/branding/themes/theme[test-red] at line 1861"

I tried adding _delta="define " at the variable level (merge at the theme level)

<branding>
<themes>
  <theme id="test-red" _delta="merge">
    <variables>
      <variable id="ibo-navigation-menu--top-part--background-color" _delta="define" >#8E8F9E</variable>
    </variables>
  </theme>
</themes>

Whilst this compiles it has no effect.
Changing to _delta="redefine" outputs an error, saying the variable doesn't exist - which sort of makes sense.

I am clearly missing something in my mental model of how this works.

Looking for some inspiration ;-)

Thanks

Tim

Hi Tim,

You should use _delta="must_exist", or no _delta at all for <theme> as it's only used for reconcilliation in this case.

However your should make sur that your module has itop-structure as depency so it'll ensure the theme exists before you alter it.
