成员函数说明

overrideVfptrFun() [1/3]

template<typename Fun1 , typename Fun2 >

template< typename Fun1, typename Fun2 > static bool Dtk::Core::DVtableHook::overrideVfptrFun ( const typename QtPrivate::FunctionPointer< Fun1 >::Object *  t1, Fun1  fun1, Fun2  fun2  )

注解

重载多继承类中的多个虚函数时，fun1务必标记成一个类名的函数。否则可能出现内存泄露的情况

例如 class A 继承于 B，C，D，当需要重载B中的foo1，C中的foo2时，以下函数的fun1需要统一标记为&A::foo1和&A::foo2

因为如果分开写为&B::foo1和&C::foo2的话，指针转换内部会记录多张虚表，重载多份析构函数，可能导致最开始的部分无法正常析构！

overrideVfptrFun() [2/3]

static bool ::type Dtk::Core::DVtableHook::overrideVfptrFun ( quintptr *  vfptr_t1, Fun1  fun1, Fun2  fun2, bool  forceWrite  )

({code}) in the form of a code is to eliminate - Wstrict - aliasing build warnings

overrideVfptrFun() [3/3]

template<typename Fun1 , typename Fun2 >

static bool Dtk::Core::DVtableHook::overrideVfptrFun ( quintptr *  vfptr_t1, Fun1  fun1, quintptr *  vfptr_t2, Fun2  fun2, bool  forceWrite  )
