function toolbar_themes_preprocess_toolbar_themes__toolbar in Toolbar Themes 8

Implements hook_preprocess_HOOK().

Piling everything into preprocess like this is probably lazy programming, but it's what I'm familiar with, if you have a better way to do some of this stuff patches are most welcome!

Parameters

$variables:

1 string reference to 'toolbar_themes_preprocess_toolbar_themes__toolbar'

toolbar_themes_theme_registry_alter in ./toolbar_themes.module

Implements hook_theme_registry_alter(). ...well this seems repetitive. TODO, abstract something or?

File

./toolbar_themes.module, line 232
