Your void ControlDialog<Base>::show() is common to all objects of type
"Base". Why don't you just use a data member? Rough draft:
template <class Base>
class ControlDialog {
...
private:
...
class State {
public:
bool isBuilt;
State() : isBuilt(false) {}
};
State state_;
};
template <class Base>
void ControlDialog<Base>::show()
{
...
if (!state_.isBuilt) {
state_.isBuilt = true;
...
}
...
}
