Struct fltk::enums::Color

pub struct Color { /* fields omitted */ }

Defines colors used by FLTK. Colors are stored as RGBI values, the last being the index for FLTK colors in this enum. Colors in this enum don’t have an RGB stored. However, custom colors have an RGB, and don’t have an index. The RGBI can be acquired by casting the color to u32 and formatting it to 0x{08x}. The last 2 digits are the hexadecimal representation of the color in this enum. For example, Color::White, has a hex of 0x000000ff, ff being the 255 value of this enum. A custom color like Color::from_u32(0x646464), will have an representation as 0x64646400, of which the final 00 indicates that it is not stored in this enum. For convenience, the fmt::Display trait is implemented so that the name of the Color is shown when there is one, otherwise the RGB value is given.
