I'm developing a BlackBerry 10 mobile application using the Momentics IDE (native SDK).
All I want is to set a label color in c++ with an hex value using the TextStyleDefinition class like below :
Label* titleLabel = container->findChild<Label*>("titleLabelObj");
TextStyleDefinition* TSD;
TSD->setColor(Color::fromARGB("#F01E21"));
titleLabel->textStyle()->setBase(TSD()->style());
The problem is that the ' fromARGB(int argb) ' fuction reclaim an int value so I tried to replace " # " by " 0x " but it doesn't work.
Can any one help me on this ? I will be very thankfull .
Color::fromARGB() expects an integer, not a string...
Try that:
#include <cstdlib>
#include <iostream>
using namespace std;
int hexToInt(string s)
{
char * p;
if (s[0]=='#') s.replace(0,1,"");
return (int)strtol(s.c_str(), &p, 16);
}
then
m_TSD->setColor(Color::fromARGB(hexToInt("#F01E21")));
Actually it was simple, you just need to precise the alpha ;
// Let's take for example the hex color below :
QString color = "#F01E21"
// We need to convert string to int after we replace the "#" with "0x"
bool ok;
int stringColorToInt = color.replace("#", "0xFF").toUInt(&ok, 16) // The 'FF' is alpha
// We set the color
TSD->setColor(Color::fromARGB(stringColorToInt));
