/*
|
||
|
|
All this is quite ugly but serves two purposes:
|
||
|
|
1. Be almost 100% compatible with old, untyped, wxList class
|
||
|
|
2. Ensure compile-time type checking for the linked lists
|
||
|
|
|
||
|
|
The idea is to have one base class (wxListBase) working with "void *" data,
|
||
|
|
but to hide these untyped functions - i.e. make them protected, so they
|
||
|
|
can only be used from derived classes which have inline member functions
|
||
|
|
working with right types. This achieves the 2nd goal. As for the first one,
|
||
|
|
we provide a special derivation of wxListBase called wxList which looks just
|
||
|
|
like the old class.

Note 1: the outer helper class _WX_LIST_HELPER_##liT below is a workaround
|
||
|
|
for mingw 3.2.3 compiler bug that prevents a static function of liT class
|
||
|
|
from being exported into dll. A minimal code snippet reproducing the bug:
|
||
|
|
|
||
|
|
struct WXDLLIMPEXP_CORE Foo
|
||
|
|
{
|
||
|
|
static void Bar();
|
||
|
|
struct SomeInnerClass
|
||
|
|
{
|
||
|
|
friend class Foo; // comment this out to make it link
|
||
|
|
};
|
||
|
|
~Foo()
|
||
|
|
{
|
||
|
|
Bar();
|
||
|
|
}
|
||
|
|
};
|
||
|
|
|
||
|
|
The program does not link under mingw_gcc 3.2.3 producing undefined
|
||
|
|
reference to Foo::Bar() function
|
||
|
|
|
||
|
|
|
||
|
|
Note 2: the EmptyList is needed to allow having a NULL pointer-like
|
||
|
|
invalid iterator. We used to use just an uninitialized iterator object
|
||
|
|
instead but this fails with some debug/checked versions of STL, notably the
|
||
|
|
glibc version activated with _GLIBCXX_DEBUG, so we need to have a separate
|
||
|
|
invalid iterator.

// wxNode-derived type)
|
||
|
|
//
|
||
|
|
// implementation details:
|
||
|
|
// 1. We define _WX_LIST_ITEM_TYPE_##name typedef to save in it the item type
|
||
|
|
// for the list of given type - this allows us to pass only the list name
|
||
|
|
// to WX_DEFINE_LIST() even if it needs both the name and the type
|
||
|
|
//
|
||
|
|
// 2. We redefine all non-type-safe wxList functions with type-safe versions
|
||
|
|
// which don't take any space (everything is inline), but bring compile
|
||
|
|
// time error checking.
|
||
|
|
//
|
||
|
|
// 3. The macro which is usually used (WX_DECLARE_LIST) is defined in terms of
|
||
|
|
// a more generic WX_DECLARE_LIST_2 macro which, in turn, uses the most
|
||
|
|
// generic WX_DECLARE_LIST_3 one. The last macro adds a sometimes
|
||
|
|
// interesting capability to store polymorphic objects in the list and is
|
||
|
|
// particularly useful with, for example, "wxWindow *" list where the
|
||
|
|
// wxWindowBase pointers are put into the list, but wxWindow pointers are
|
||
|
|
// retrieved from it.
|
||
|
|
//
|
||
|
|
// 4. final hack is that WX_DECLARE_LIST_3 is defined in terms of
|
||
|
|
// WX_DECLARE_LIST_4 to allow defining classes without operator->() as
|
||
|
|
// it results in compiler warnings when this operator doesn't make sense
|
||
|
|
// (i.e. stored elements are not pointers)
|
