Function overriding with argument inheritance -


I have a general item list class, to create a more specific list that uses it as a base class, Some .. 

  Referee class item-badge {} referee class item one: itembase {} Ref Class Maddist summary {public: Add virtual zero (item box ^ P); } Ref class item list A: Madlist (public: Add virtual zeros (alcoholia ^ P) override; // This does not work :(}

I want to control adding.

accepted pattern base class method protected < / Code> Creating: 

  Ref Class Item Box {ref} Category Item: Item: Item Buzz {} Ref Slash Item Element Essentials {Protected: Virtual Zero addInternal (Item Box ^ P);} Ref Class Item List A: Radial {Public: Virtual Zero Addition (Item A ^ P) {addInternal (p);}}  < / Pre> 
 Here's a better solution for using generic. Note that how do we force the normal parameter  T  to  ItemBase , implement it For that this collection should only be used with  ItemBase  or its subclasses. 
 
  Referred The class item item {}; Ref class item: public itembase {}; generic & lt; Class T & gt; Where T: itembash ref class itemlist summary {public: add virtual zeros (tp) {}}; Ref Class item item: list: item list & lieutenant; Item A ^> {// no add here to override Ed}; // use int main (array  args) {item list a ^ list = gcnu mandista (); List-> Add (GCNE alcoholicum); }

Eclipse CDT variable colors in editor -

I hope this is a good question to ask here. This programming is related, so I thought it would be better than the superuser, so I am using the CDT C ++ Eclipse plugin. I know how the editor changes colors for some things But is there a way to do that all the variables are different colors? For example in KDEValue, it sets the local variables and square variables in different colors and bold square squares. Can I copy it to CDT? Eclips provides some level of color customization for text editor syntax You can see it on the following: There are many elements, including the Window> Preferences> C / C ++> Editor> Syntax color code that can be changed, assembly, Comments, Preprocessor and Doxian Under the code, it is possible to change the color of some variable types, such as global variables, local variable announcements, local variable references, and parameter variables. But I do not think the code is capable of changing the color of each variable declared....
