* MRU-Functions {COMCTL32}
|
||||
*
|
||||
* NOTES
|
||||
* The MRU-API is a set of functions to manipulate lists of M.R.U. (Most Recently
|
||||
* Used) items. It is an undocumented API that is used (at least) by the shell
|
||||
* and explorer to implement their recent documents feature.
|
||||
*
|
||||
* Since these functions are undocumented, they are unsupported by MS and
|
||||
* may change at any time.
|
||||
*
|
||||
* Internally, the list is implemented as a last in, last out list of items
|
||||
* persisted into the system registry under a caller chosen key. Each list
|
||||
* item is given a one character identifier in the Ascii range from 'a' to
|
||||
* '}'. A list of the identifiers in order from newest to oldest is stored
|
||||
* under the same key in a value named "MRUList".
|
||||
*
|
||||
* Items are re-ordered by changing the order of the values in the MRUList
|
||||
* value. When a new item is added, it becomes the new value of the oldest
|
||||
* identifier, and that identifier is moved to the front of the MRUList value.
|
||||
*
|
||||
* Wine stores MRU-lists in the same registry format as Windows, so when
|
||||
* switching between the builtin and native comctl32.dll no problems or
|
||||
* incompatibilities should occur.
|
||||
*
|
||||
* The following undocumented structure is used to create an MRU-list:
|
||||
*|typedef INT (CALLBACK *MRUStringCmpFn)(LPCTSTR lhs, LPCTSTR rhs);
|
||||
*|typedef INT (CALLBACK *MRUBinaryCmpFn)(LPCVOID lhs, LPCVOID rhs, DWORD length);
|
||||
*|
|
||||
*|typedef struct tagMRUINFO
|
||||
*|{
|
||||
*| DWORD cbSize;
|
||||
*| UINT uMax;
|
||||
*| UINT fFlags;
|
||||
*| HKEY hKey;
|
||||
*| LPTSTR lpszSubKey;
|
||||
*| PROC lpfnCompare;
|
||||
*|} MRUINFO, *LPMRUINFO;
|
||||
*
|
||||
* MEMBERS
|
||||
* cbSize [I] The size of the MRUINFO structure. This must be set
|
||||
* to sizeof(MRUINFO) by the caller.
|
||||
* uMax [I] The maximum number of items allowed in the list. Because
|
||||
* of the limited number of identifiers, this should be set to
|
||||
* a value from 1 to 30 by the caller.
|
||||
* fFlags [I] If bit 0 is set, the list will be used to store binary
|
||||
* data, otherwise it is assumed to store strings. If bit 1
|
||||
* is set, every change made to the list will be reflected in
|
||||
* the registry immediately, otherwise changes will only be
|
||||
* written when the list is closed.
|
||||
* hKey [I] The registry key that the list should be written under.
|
||||
* This must be supplied by the caller.
|
||||
* lpszSubKey [I] A caller supplied name of a subkey under hKey to write
|
||||
* the list to. This may not be blank.
|
||||
* lpfnCompare [I] A caller supplied comparison function, which may be either
|
||||
* an MRUStringCmpFn if dwFlags does not have bit 0 set, or a
|
||||
* MRUBinaryCmpFn otherwise.
|
||||
*
|
||||
* FUNCTIONS
|
||||
* - Create an MRU-list with CreateMRUList() or CreateMRUListLazy().
|
||||
* - Add items to an MRU-list with AddMRUString() or AddMRUData().
|
||||
* - Remove items from an MRU-list with DelMRUString().
|
||||
* - Find data in an MRU-list with FindMRUString() or FindMRUData().
|
||||
* - Iterate through an MRU-list with EnumMRUList().
