Gdk::Color to HTML Format Hex

Desktop Ruby-Gnome 2
1

I’m trying to convert the hex code that Gdk::Color.to_s() returns into
HTML Format Hex. I think what needs to be done is some math on the
string, but I’m fairly new to ruby and not sure how to do this. For
instance, if the color in HTML hex is a six string code, #ffffff, then
Gdk::Color would return #ffffffffffff.

Here is an example of how to do it in C, but I’m not sure how to
translate that to ruby.

Thanks in advance.

str = (color.red >> 8).to_s(16)
str += (color.green >> 8).to_s(16)
str += (color.blue >> 8).to_s(16)

Scrap that: “#%02x%02x%02x” % [c.red, c.green, c.blue]
