+ Helper function appending the checkable items corresponding to all the
+ columns to the given menu.
+
+ This function is used by ShowColumnsMenu() but can also be used if you
+ show your own custom columns menu and still want all the columns shown
+ in it. It appends menu items with column labels as their text and
+ consecutive ids starting from @a idColumnsBase to the menu and checks
+ the items corresponding to the currently visible columns.
+
+ Example of use:
+ @code
+ wxMenu menu;
+ menu.Append(100, "Some custom command");
+ menu.AppendSeparator();
+ AddColumnsItems(menu, 200);
+ const int rc = GetPopupMenuSelectionFromUser(menu, pt);
+ if ( rc >= 200 )
+ ... toggle visibility of the column rc-200 ...
+ @endcode
+
+ @param menu
+ The menu to append the items to. It may be currently empty or not.
+ @param idColumnsBase
+ The id for the menu item corresponding to the first column, the
+ other ones are consecutive starting from it. It should be positive.
