Virtual Destructors ?

[Themuppeteer]

Who can tell me somthing about virtual destructors?
I need them but don't know how to use them.

eg.

I have an class called drawings;
Also I have a new class derived from drawings calls circle,and another class derived from drawings calls rectangle.

If I create an array of pointers to "drawings" , the destructor of the class drawings will be called,when I delete the array. I don't want that, because the array contains circles and rectangles. The only possible solution:virtual destructors.


Any help would be great.


thnx.

yes, I found it.

just make the base class destructor virtual and the childrens destructor will be called automatically.
That easy! Greetz,
