c++ - How To change the background color of a container using the Hex format? -

i'm developing blackberry 10 mobile application using momentics ide (native sdk).

i want change background color of container using c++. unfortunately, relating [link], can define below :

**creating color in c++:** color c1 = color::fromrgba(0.5f, 1.0f, 0.2f, 0.8f); color c2 = color::fromargb(0xff996633); 

for color, want use hex format ("#xxxxxx"). 1 can guide me on ?

color c2 = color::fromargb(0xff996633); using hex 0x c++ representation of hex code. ff component, 99 r, 66 g , 33 b

so if want use hex value #000099 no alpha

then

color::fromargb(0x00000099) 

the following code convert string hex value, need remove # string before hand however, , can pass string buffer object

#include <iostream> #include <sstream>  int main() {       std::string hexstring("#ffffff");     hexstring.erase(hexstring.begin());      std::istringstream buffer(hexstring);      int value;      buffer >> std::hex >> value;      std::cout << std::hex << value;     return 0; }
