## Detailed Description

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.

## Constructor & Destructor Documentation

wxFileHistory::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.

virtual wxFileHistory::~wxFileHistory | ( |  | ) |

virtual

Destructor.

## Member Function Documentation

virtual void wxFileHistory::AddFilesToMenu | ( |  | ) |

virtual

virtual

Appends the files in the history list, to the given menu only.

virtual void wxFileHistory::AddFileToHistory | ( | const wxString & | filename | ) |

virtual

Adds a file to the file history list, if the object has a pointer to an appropriate file menu.

wxWindowID wxFileHistory::GetBaseId | ( |  | ) | const

Returns the base identifier for the range used for appending items.

virtual size_t wxFileHistory::GetCount | ( |  | ) | const

virtual

Returns the number of files currently stored in the file history.

virtual void wxFileHistory::Load | ( | const wxConfigBase & | config | ) |

virtual

Loads the file history from the given config object.

This function should be called explicitly by the application.

virtual void wxFileHistory::RemoveFileFromHistory | ( | size_t | i | ) |

virtual

Removes the specified file from the history.

virtual void wxFileHistory::RemoveMenu | ( | wxMenu * | menu | ) |

virtual

Removes this menu from the list of those managed by this object.
