Detailed Description

The QFileSystemModel class provides a data model for the local filesystem.

This class provides access to the local filesystem, providing functions for renaming and removing files and directories, and for creating new directories. In the simplest case, it can be used with a suitable display widget as part of a browser or filter.

QFileSystemModel can be accessed using the standard interface provided by QAbstractItemModel, but it also provides some convenience functions that are specific to a directory model. The fileInfo(), isDir(), name(), and path() functions provide information about the underlying files and directories related to items in the model. Directories can be created and removed using mkdir(), rmdir().

Note: QFileSystemModel requires an instance of a GUI application.

Example Usage

A directory model that displays the contents of a default directory is usually constructed with a parent object:

QFileSystemModel *model = new QFileSystemModel;

model->setRootPath(QDir::currentPath());

A tree view can be used to display the contents of the model

QTreeView *tree = new QTreeView(splitter);

tree->setModel(model);

and the contents of a particular directory can be displayed by setting the tree view's root index:

tree->setRootIndex(model->index(QDir::currentPath()));

The view's root index can be used to control how much of a hierarchical model is displayed. QDirModel(obsolete) provides a convenience function that returns a suitable model index for a path to a directory within the model.

Caching and Performance

QFileSystemModel will not fetch any files or directories until setRootPath() is called. This will prevent any unnecessary querying on the file system until that point such as listing the drives on Windows.

Unlike QDirModel(obsolete), QFileSystemModel uses a separate thread to populate itself so it will not cause the main thread to hang as the file system is being queried. Calls to rowCount() will return 0 until the model populates a directory.

QFileSystemModel keeps a cache with file information. The cache is automatically kept up to date using the QFileSystemWatcher.

new bool QtGui.QFileSystemModel.Remove ( QModelIndex  index)

Removes the model item index from the file system model and deletes the corresponding file from the file system, returning true if successful. If the item cannot be removed, false is returned.

Warning: This function deletes files from the file system; it does not move them to a location where they can be recovered.

See also rmdir().

new bool QtGui.QFileSystemModel.Rmdir ( QModelIndex  index)

Removes the directory corresponding to the model item index in the file system model and deletes the corresponding directory from the file system, returning true if successful. If the directory cannot be removed, false is returned.

Warning: This function deletes directories from the file system; it does not move them to a location where they can be recovered.

See also remove().

object  value,
int  role = (int) Qt.ItemDataRole.EditRole 
)
virtual

Reimplemented from QAbstractItemModel::setData().

See also data().

Reimplemented from QtCore.QAbstractItemModel.

new QModelIndex QtGui.QFileSystemModel.SetRootPath ( string  path)

Sets the directory that is being watched by the model to newPath by installing a file system watcher on it. Any changes to files and directories within this directory will be reflected in the model.

If the path is changed, the rootPathChanged() signal will be emitted.

Note: This function does not change the structure of the model or modify the data available to views. In other words, the "root" of the model is not changed to include only files and directories within the directory specified by newPath in the file system.

See also rootPath().

new long QtGui.QFileSystemModel.Size ( QModelIndex  index)

Returns the size in bytes of index. If the file does not exist, 0 is returned.

Property Documentation

Slot<System.String> QtGui.QFileSystemModel.DirectoryLoaded
addremove

This signal is emitted when the gatherer thread has finished to load the path.

This function was introduced in Qt 4.7.

new IQFileSystemModelSignals QtGui.QFileSystemModel.Emit
getprotected
Slot<System.String,System.String,System.String> QtGui.QFileSystemModel.FileRenamed
addremove

This signal is emitted whenever a file with the oldName is successfully renamed to newName. The file is located in in the directory path.

new QDir.Filter QtGui.QFileSystemModel.Filter
getset

Returns the filter specified for the directory model.

If a filter has not been set, the default filter is QDir::AllEntries | QDir::NoDotAndDotDot | QDir::AllDirs.

Sets the directory model's filter to that specified by filters.

Note that the filter you set should always include the QDir::AllDirs enum value, otherwise QFileSystemModel won't be able to read the directory structure.

new QFileIconProvider QtGui.QFileSystemModel.IconProvider
getset

Returns the file icon provider for this directory model.

Sets the provider of file icons for the directory model.

new bool QtGui.QFileSystemModel.NameFilterDisables
getset

This property holds whether files that don't pass the name filter are hidden or disabled.

This property is true by default

new System.Collections.Generic.List<string> QtGui.QFileSystemModel.NameFilters
getset

Returns a list of filters applied to the names in the model.

Sets the name filters to apply against the existing files.

new bool QtGui.QFileSystemModel.ReadOnly
getset

This property holds whether the directory model allows writing to the file system.

If this property is set to false, the directory model will allow renaming, copying and deleting of files and directories.

This property is true by default

new bool QtGui.QFileSystemModel.ResolveSymlinks
