CBasePane implements the following virtual Boolean methods to reflect these flags: CBasePane::CanBeClosed, CBasePane::CanAutoHide, CBasePane::CanFloat. You can override them in derived classes to customize their behavior.You can customize docking behavior by overriding CBasePane::CanAcceptPane....
Note that calling a specific explicitly qualified function is not a virtual call even if the function is virtual. 注意:调用一个特定的限定函数不是虚调用,即使这个函数是虚函数。 See also factory functions for how to achieve the effect of a call to a derived class function without risking undefine...
You can override it to invalidate only those regions of the client area that map to the modified portions of the document.To use CView, derive a class from it and implement the OnDraw member function to perform screen display. You can also use OnDraw to perform printing and print preview...
