Manages a set of files for use as a list of recently-opened documents.
This is a handy class for holding your list of recently-opened documents, with helpful methods for things like purging any non-existent files, automatically adding them to a menu, and making persistence easy.

juce::RecentlyOpenedFilesList::RecentlyOpenedFilesList | ( | ) |
Creates an empty list.
void juce::RecentlyOpenedFilesList::addFile | ( | const File & | file | ) |
Adds a file to the list.
The file will be added at index 0. If this file is already in the list, it will be moved up to index 0, but a file can only appear once in the list.
If the list already contains the maximum number of items that is permitted, the least-recently added file will be dropped from the end.
void juce::RecentlyOpenedFilesList::clear | ( | ) |
Clears all the files from the list.
|
static |
Tells the OS to clear the OS-managed list of recent documents for this app.
Not all OSes maintain a list of recent files for an application, so this function will have no effect on some OSes. Currently it's just implemented for OSX.
int juce::RecentlyOpenedFilesList::createPopupMenuItems | ( | PopupMenu & | menuToAddItemsTo, |
int | baseItemId, | ||
bool | showFullPaths, | ||
bool | dontAddNonExistentFiles, | ||
const File ** | filesToAvoid = nullptr |
||
) |
Adds entries to a menu, representing each of the files in the list.
This is handy for creating an "open recent file..." menu in your app. The menu items are numbered consecutively starting with the baseItemId value, and can either be added as complete pathnames, or just the last part of the filename.
If dontAddNonExistentFiles is true, then each file will be checked and only those that exist will be added.
If filesToAvoid is not a nullptr, then it is considered to be a zero-terminated array of pointers to file objects. Any files that appear in this list will not be added to the menu - the reason for this is that you might have a number of files already open, so might not want these to be shown in the menu.
It returns the number of items that were added.

inlinenoexcept |
Returns an array of all the absolute pathnames in the list.
References juce::UnitTestCategories::files.
Returns one of the files in the list.
The most recently added file is always at index 0.
|
inlinenoexcept |
Returns the number of items that this list will store.
int juce::RecentlyOpenedFilesList::getNumFiles | ( | ) | const |
Returns the number of files in the list.
The most recently added file is always at index 0.

void juce::RecentlyOpenedFilesList::removeFile | ( | const File & | file | ) |
Removes a file from the list.
void juce::RecentlyOpenedFilesList::removeNonExistentFiles | ( | ) |
Checks each of the files in the list, removing any that don't exist.
You might want to call this after reloading a list of files, or before putting them on a menu.
void juce::RecentlyOpenedFilesList::restoreFromString | ( | const String & | stringifiedVersion | ) |
Restores the list from a previously stringified version of the list.
Pass in a stringified version created with toString() in order to persist/restore your list.
void juce::RecentlyOpenedFilesList::setMaxNumberOfItems | ( | int | newMaxNumber | ) |
Sets a limit for the number of files that will be stored in the list.
When addFile() is called, then if there is no more space in the list, the least-recently added file will be dropped.
String juce::RecentlyOpenedFilesList::toString | ( | ) | const |
Returns a string that encapsulates all the files in the list.
The string that is returned can later be passed into restoreFromString() in order to recreate the list. This is handy for persisting your list, e.g. in a PropertiesFile object.
