I wish this helpful for you It doesn't work with the current C++03, but C++0x will allow to initialize i.e. std::vector with

Are Qt's stylesheets really handling _dynamic_ properties?

Hope this helps I found a quick, although a bit hackish, way to update widget's styling.
code :
myWidget->style()->unpolish(myWidget);
myWidget->ensurePolished();

Unknown error in array initialization: invalid in-class initialization of static data member of non- integral type `cons

wish help you to fix your issue Like it says, you cannot initialize static non-integral types in a class definition. That is, you could do this:
code :
static const unsigned value = 123;
static const bool value_again = true;
static const unsigned char cycles_table[256];
const unsigned char i8080::cycles_table[256] = // ...

How to make inline array initialization work like e.g. Dictionary initialization?

wish of those help The collection initializer syntax is translated into calls to Add with the appropriate number of parameters:
code :
var dict = new Dictionary<string,int>();
dict.Add("key1", 1);
dict.Add("key2", 2);
// Don't do this in production code!
class CrazyAdd : IEnumerable
{
    public void Add(int x, int y, int z)
    {
        Console.WriteLine(x + y + z); // Well it *does* add...
    }

    public IEnumerator GetEnumerator() { throw new NotImplementedException(); }
}
var crazyAdd = new CrazyAdd
{
    {1, 2, 3},
    {4, 5, 6}
};

Programmatic initialization of a long array at compile or initialization time

hope this fix your issue Here is a code snippet illustrating my question: , You could initialize A during dynamic initialization time as follows:
code :
const float *init_a(float x_)
{
  static float data[4];
  for(unsigned i=0; i<4; ++i)
    data[i]=sin(i*x_);
  return data;
}

const float D=0.1f;
const float *A=init_a(D);

How to convert template-sized array initialization to constexpr initialization?

wish of those help They're not guaranteed to be strictly accurate, but they might be good enough for your purposes.
I just used the Taylor-series approximations. Add constexpr and see if they work.
