* 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 tagCREATEMRULIST
|
|
*|{
|
|
*| DWORD cbSize;
|
|
*| DWORD nMaxItems;
|
|
*| DWORD dwFlags;
|
|
*| HKEY hKey;
|
|
*| LPTSTR lpszSubKey;
|
|
*| PROC lpfnCompare;
|
|
*|} CREATEMRULIST, *LPCREATEMRULIST;
|
|
*
|
|
* MEMBERS
|
|
* cbSize [I] The size of the CREATEMRULIST structure. This must be set
|
|
* to sizeof(CREATEMRULIST) by the caller.
|
|
* nMaxItems [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.
|
|
* dwFlags [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().
|
|
* - Free an MRU-list with FreeMRUList().
