C++ (Cpp) set_item_count Examples

Example #1

File: slider.cpp Project: GregoryLundberg/wesnoth

void slider::set_maximum_value(const int maximum_value)
{
    if(maximum_value == get_maximum_value()) {
        return;
    }

    /** @todo maybe make it a VALIDATE. */
    assert(minimum_value_ <= maximum_value);

    const int value = get_value();

    // The number of items needs to include the begin and end so distance + step
    // size.
    set_item_count(maximum_value - minimum_value_ + get_step_size());

    if(value > maximum_value) {
        set_item_position(get_maximum_value());
    }
}

Example #2

{

	const int value = get_value();

	// The number of items needs to include the begin and end so distance + 1.
	set_item_count(distance(minimum_value_, maximum_value) + 1);

	if(value > maximum_value) {
		set_item_position(get_maximum_value());
	} else {
		set_item_position(minimum_value_ + value);
	}
}

Example #3
