So make it pure virtual:
vitual CommandInfo const * findInfo(std::string const & cmdName) = 0;
I didn't do that because it needs, at least in the base classes, to
be static, and I wanted to indicate here that it needed to be
implemented as a static function. But of course "virtual static" is
out, and so is "static blah =0". Thoughts?
class Base
{
public:
static Foo findInfo() { return doFindInfo(); }
protected:
virtual Foo doFindInfo() const = 0;
};
class Derived : public Base
{
protected:
virtual Foo doFindInfo() const { return Something; }
};
Thanks!
Spoke to son. This fails:
../../../src/insets/InsetCommand.h: In static member function 'static
const lyx::CommandInfo* lyx::InsetCommand::findInfo(const std::string&)':
../../../src/insets/InsetCommand.h:83: error: cannot call member
function 'virtual const lyx::CommandInfo*
lyx::InsetCommand::doFindInfo(const std::string&)' without object
I take it that the problem is that doFindInfo() is a member function
being called from a static function, and so there is no `this'.
