Hi!

When using "Implements Methods" on below sample class VA want's to implement the pure virtual method, too. That's not correct.

class test
{
test();
~test();
virtual void pure() = 0;
};

However not usually used, implementing pure virtual methods are valid. For example, the below code happily compiles:

class testclass
{
public:
testclass() {}
~testclass () {}
virtual void pure() = 0 {};
};

class superclass : public testclass
{
superclass() {}
~superclass() {}
virtual void pure() { testclass::pure(); }
};

Mmmhh, to my surprise you're right. I didn't encounter any occasion yet with an implemented pure virtual function. So it't correct, sorry.

Thus I think the best would be to have a check box to decide whether to implement pure virtual functions, too.

Because it takes some doing in a bigger header to uncheck all the virtual functions. (You have to find them first beacuse they are not marked in the overview.) Or at least at a "= 0" in the list.
