StyleContext.addClass
void addClass(string className)Adds a style class to context, so posterior calls to [gtk.style_context.StyleContext.get] or any of the gtk_render_*() functions will make use of this new class for styling.
In the CSS file format, a #GtkEntry defining a “search” class, would be matched by:
`` <!-- language="CSS" -->
entry.search { ... }
CODEBLOCK0 <!-- language="CSS" -->
.search { ... }
``
Parameters
className | class name to use in styling |
