    \ingroup qmlmodules
    \brief The FolderListModel provides a model of the contents of a file system folder.
 
    To use this module, import the module with the following line:
 
    \qml
    import Qt.labs.folderlistmodel
    \endqml
*/
 
/*!
    \qmltype FolderListModel
    \inqmlmodule Qt.labs.folderlistmodel
//!    \nativetype QQuickFolderListModel
    \ingroup qtquick-models
    \brief The FolderListModel provides a model of the contents of a file system folder.
 
    FolderListModel provides access to information about the contents of a folder
    in the local file system, exposing a list of files to views and other data components.
 
    \note This type is made available by importing the \c Qt.labs.folderlistmodel module.
    \e{Elements in the Qt.labs module are not guaranteed to remain compatible
    in future versions.}
 
    \note Some features in FolderListModel depend on \l QFileSystemWatcher. If \l QFileSystemWatcher
    is disabled, the folder set using \c setFolder is not watched for changes, which results in
    signals typically emitted on directory changes (like directoryUpdated or directoryChanged) not
    being emitted without manually calling \c setFolder again. For more information, see
    \l{Qt Configure Options}.
 
    \qml
    import Qt.labs.folderlistmodel
    \endqml
 
    The \l folder property specifies the folder to access. Information about the
    files and directories in the folder is supplied via the model's interface.
    Components access names and paths via the following roles:
 
    \list
    \li \c fileName (\c string)
    \li \c filePath (\c string)
    \li \c fileUrl (\c url) (since Qt 5.15)
    \li \c fileBaseName (\c string)
    \li \c fileSuffix (\c string)
    \li \c fileSize (\c qlonglong)
    \li \c fileModified (\c date)
    \li \c fileAccessed (\c date)
    \li \c fileIsDir (\c bool)
    \endlist
 
    Additionally a file entry can be differentiated from a folder entry via the
    isFolder() method.
 
    \section1 Filtering
 
    Various properties can be set to filter the number of files and directories
    exposed by the model.
 
    The \l nameFilters property can be set to contain a list of wildcard filters
    that are applied to names of files and directories, causing only those that
    match the filters to be exposed.
 
    Directories can be included or excluded using the \l showDirs property,
    navigation directories can also be excluded by setting the \l showDotAndDotDot
    property to false, hidden files can be included or excluded using the
    \l showHidden property.
 
    It is sometimes useful to limit the files and directories exposed to those
    that the user can access. The \l showOnlyReadable property can be set to
    enable this feature.
 
    \section1 Example Usage
 
    The following example shows a FolderListModel being used to provide a list
    of QML files in a \l ListView:
 
    \qml
    import QtQuick
    import Qt.labs.folderlistmodel
 
    ListView {
        width: 200; height: 400
 
        FolderListModel {
            id: folderModel
            nameFilters: ["*.qml"]
        }
 
        Component {
            id: fileDelegate
            required property string fileName
            Text { text: fileName }
        }
 
        model: folderModel
        delegate: fileDelegate
    }
    \endqml
 
    \section1 Path Separators
 
    Qt uses "/" as a universal directory separator in the same way that "/" is
    used as a path separator in URLs. If you always use "/" as a directory
    separator, Qt will translate your paths to conform to the underlying
    operating system.
