[MonoDevelop] Gdk# Color Parse function

[Abdul Rauf]

Thanks for your reply. I am passing Gdk.Color.ToString() which is of the
form rgb:ffff/0/0
Here is a snippet:

Gdk.Color colour1 = new Gdk.Color(255, 0, 0); //red
Gdk.Color colour2 = new Gdk.Color(255, 255, 0); //Yellow
        bool result = Gdk.Color.Parse("red", ref colour2);

In this scenario, the colour2 variable changes from yellow to red and the
function returns true. However if I passes the string as follows:

Gdk.Color colour1 = new Gdk.Color(255, 0, 0); //red
Gdk.Color colour2 = new Gdk.Color(255, 255, 0); //Yellow
        bool result = Gdk.Color.Parse(colour1.ToString(), ref colour2); //
rgb:ffff/0/0

the colour2 variable remains yellow and the function returns false.

Regards
Rauf
