. Uncover late-bound secretsWhat is the late binding of virtual functions implemented by the compiler? Let's find out.The compiler creates a table (calledV ta B L E ). InIn V ta B L E, the compiler places the virtual function address of a specific class. In each class with a virtual functionThe compiler secretly sets a pointer, calledV p o I n t e r (abbreviatedV p t r), pointing to the object'sV ta B L E. Implement Virtual function calling through base class pointersWhen the compiler is statica

Then, in handleevent, the key event is sent to tabpane for processing. If it is processed (it indicates that the left and right direction keys are pressed ), you also need to load the menu (that is, load the corresponding component according to the index of the tab currently changed ).
