Qt connect() SLOT and “this” pointer

Question

The following code works:

connect(ui.pushButton, SIGNAL(clicked()), this, SLOT(myMemberFunction()));

---

That other doesn't:

connect(ui.pushButton, SIGNAL(clicked()), this, SLOT(this->myMemberFunction()));

---

Why?

Answer 1

SLOT（）宏编写了一个可以调用（作为函数指针）以交付插槽的函数，它使用参数作为名称，但它本身并不是函数调用。
