[RESOLVED] None of the 2 overloads could convert all the argument types

[Mybowlcut]

Hey.

Got a really stupid problem. I get the errors below from the first call below to set_from_slider_value. I tried casting the arguments to the parameters the function takes, but no cigar. I then created x and sv2, and passed 0 and 100 as min and max, and that worked...

void Board::Set_Computer_Delay(const Slider_Value& sv)
{
    set_from_slider_value(sv, computer_delay, min_computer_delay, max_computer_delay);
    int x = 0;
    Slider_Value sv2(23, 34);
    set_from_slider_value(sv2, x, 0, 100);
}

computer_delay, min_computer_delay and max_computer delay are declared as:

unsigned short	min_computer_delay; // Minimum computer delay in milliseconds.
unsigned short	 max_computer_delay; // Maximum computer delay in milliseconds.
unsigned short	 computer_delay; // Seconds it takes for the computer to make a move.

The set_from_slider_value functions:

int& set_from_slider_value(const Slider_Value& sv, int& value, int min, int max);
// Exactly the same as above except doesn't clamp.
int& set_from_slider_value(const Slider_Value& sv, int& value, int max);

int& set_from_slider_value(const Slider_Value& sv, int& value, int min, int max)
{
    if(sv.denominator == 0)
    {
        throw LRE_Exception("Tried to divide by zero in " + std::string(__FUNCTION__) + '.');
    }
    value = std::max(min, std::min(sv.numerator * max / sv.denominator, max));
    return value;
}

int& set_from_slider_value(const Slider_Value& sv, int& value, int max)
{
    if(sv.denominator == 0)
    {
        throw LRE_Exception("Tried to divide by zero in " + std::string(__FUNCTION__) + '.');
    }
    value = sv.numerator * max / sv.denominator;
    return value;
}

Cheers.
