But when I try to use it, I get the following errors:
Warning: C preprocessor directive #e9e9e9 is not supported
Warning: C preprocessor directive #d6d6d6 is not supported
I thought it was odd having 'q' in front of the opening curly
brace... is this a typo? Shorthand for "string quote"?
Something like that?
Or do I need to escape these somehow?
They are named "token string" and contained code must be a
valid d code. See https://dlang.org/spec/lex.html#token_strings
Thanks, Andrea and Max.
Turns out there's a simpler way to inject CSS into D code. In
case anyone else comes looking, I found that instead of an
enum, a string will do. Here's the solution I came up with to
make visible tabs in a Notebook:
That should have been:
class CSS // GTK4 compliant
{
CssProvider provider;
string myCSS = "tab { background-color: #f2f2f2; }";
this(StyleContext styleContext)
{
provider = new CssProvider();
provider.loadFromData(myCSS);
styleContext.addProvider(provider,
GTK_STYLE_PROVIDER_PRIORITY_APPLICATION);
} // this()
} // class CSS
The CSS path/file name isn't needed.
