MethodsDetailed DescriptionFolderListModel 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 Qt.labs.folderlistmodel module. Elements in the Qt.labs module are not guaranteed to remain compatible in future versions. import Qt.labs.folderlistmodel 1.0 The 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:
Additionally a file entry can be differentiated from a folder entry via the isFolder() method. FilteringVarious properties can be set to filter the number of files and directories exposed by the model. The 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 showDirs property, and navigation directories can also be excluded by setting the showDotAndDotDot property to false. It is sometimes useful to limit the files and directories exposed to those that the user can access. The showOnlyReadable property can be set to enable this feature. Example UsageThe following example shows a FolderListModel being used to provide a list of QML files in a ListView: import QtQuick 1.0 import Qt.labs.folderlistmodel 1.0 ListView { width: 200; height: 400 FolderListModel { id: folderModel nameFilters: ["*.qml"] } Component { id: fileDelegate Text { text: fileName } } model: folderModel delegate: fileDelegate } Path SeparatorsQt 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. See also QML Data Models. Property DocumentationReturns the number of items in the current folder that match the filter criteria. The folder property holds a URL for the folder that the model is currently providing. The value is a URL expressed as a string, and must be a file: or qrc: URL, or a relative URL. By default, the value is an invalid URL. The nameFilters property contains a list of file name filters. The filters may include the ? and * wildcards. The example below filters on PNG and JPEG files: FolderListModel { nameFilters: [ "*.png", "*.jpg" ] } Note: Directories are not excluded by filters. If true, directories are included in the model; otherwise only files are included. By default, this property is true. Note that the nameFilters are not applied to directories. See also showDotAndDotDot. If true, the "." and ".." directories are included in the model; otherwise they are excluded. By default, this property is false. See also showDirs. If true, only readable files and directories are shown; otherwise all files and directories are shown. By default, this property is false. See also showDirs. The sortField property contains field to use for sorting. sortField may be one of:
See also sortReversed. If set to true, reverses the sort order. The default is false. See also sortField. Method DocumentationReturns true if the entry index is a folder; otherwise returns false. |
