Problems with inheritance

I've got a little problem. I don't know how can I rewrite a method form base class. I rewrote it, but it isn't called. Could you tell me what I'm doing wrong? Compilation was done without errors or warnings.
Thanx.

C is nothing more than a portable assembler.

RE: Problems with inheritance

In order to override a method the declaration must be exactly the same. That is probably the reason to your problem. From a brief peak at your code the only such problem I can spot if that your event handling methods are not protected as in the class that you inherit. I do not know if this is the problem though.

No the problem in your code is that you don't create the view widget with new.

write:
new View(this);

instead of:
View v(this);

The problem is that after the constructor your object does not exist anymore, and this is why it is not showed at all.
