The wxFileHistory encapsulates a user interface convenience, the list of most recently visited files as shown on a menu (usually the File menu).
wxFileHistory can manage one or more file menus. More than one menu may be required in an MDI application, where the file history should appear on each MDI child menu as well as the MDI parent frame.
wxFileHistory overview, wxDocManager
A character array of strings corresponding to the most recently opened files.
The number of files stored in the history array.
The maximum number of files to be stored and displayed on the menu.
The file menu used to display the file history list (if enabled).
wxFileHistory(size_t maxFiles = 9, wxWindowID idBase = wxID_FILE1)
Constructor. Pass the maximum number of files that should be stored and displayed.
idBase defaults to wxID_FILE1 and represents the id given to the first history menu item. Since menu items can't share the same ID you should change idBase (To one of your own defined IDs) when using more than one wxFileHistory in your application.
void AddFileToHistory(const wxString& filename)
Adds a file to the file history list, if the object has a pointer to an appropriate file menu.
Appends the files in the history list, to all menus managed by the file history object.
void AddFilesToMenu(wxMenu* menu)
Appends the files in the history list, to the given menu only.
wxString GetHistoryFile(size_t index) const
Returns the file at this index (zero-based).
size_t GetMaxFiles() const
Returns the maximum number of files that can be stored.
size_t GetCount() const
Returns the number of files currently stored in the file history.
void Load(wxConfigBase& config)
Loads the file history from the given config object. This function should be called explicitly by the application.
void RemoveFileFromHistory(size_t i)
Removes the specified file from the history.
void RemoveMenu(wxMenu* menu)
Removes this menu from the list of those managed by this object.
void Save(wxConfigBase& config)
Saves the file history into the given config object. This must be called explicitly by the application.
void UseMenu(wxMenu* menu)
Adds this menu to the list of those menus that are managed by this file history object. Also see AddFilesToMenu() for initializing the menu with filenames that are already in the history when this function is called, as this is not done automatically.
