Ahhhhh! Well spotted.
Wouldn't it be cleaner to do
template <class Inset, class Params>
void ControlInset<Inset, Params>::show(Params const & params)
{
if (params_) delete params_;
params_ = new Params(params);
setDaughterParams();
+ static bool isBuilt = false;
+ if (!isBuilt) {
+ isBuilt = true;
+ view().build();
+ }
bc().readOnly(isReadonly());
view().show();
}
