  • def refresh ([parent=QModelIndex()])

Detailed Description

The usage of QDirModel is not recommended anymore. The QFileSystemModel class is a more performant alternative.

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 filer.

QDirModel keeps a cache with file information. The cache needs to be updated with refresh() .

QDirModel 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() and isDir() functions provide information about the underlying files and directories related to items in the model.

Directories can be created and removed using mkdir() , rmdir() , and the model will be automatically updated to take the changes into account.

Note

QDirModel requires an instance of QApplication .

This constructor is deprecated.

param parent:

PySide2.QtCore.QObject

param nameFilters:

list of strings

param filters:

Filters

Description

QDirModel.FileIconRole

QDirModel.FilePathRole

QDirModel.FileNameRole
PySide2.QtWidgets.QDirModel.fileIcon(index)
Parameters:

index – PySide2.QtCore.QModelIndex

Return type:

PySide2.QtGui.QIcon

Returns the icons for the item stored in the model under the given index .

PySide2.QtWidgets.QDirModel.fileInfo(index)
Parameters:

index – PySide2.QtCore.QModelIndex

Return type:

PySide2.QtCore.QFileInfo

Returns the file information for the specified model index .

Note

If the model index represents a symbolic link in the underlying filing system, the file information returned will contain information about the symbolic link itself, regardless of whether resolveSymlinks is enabled or not.

PySide2.QtWidgets.QDirModel.fileName(index)
Parameters:

index – PySide2.QtCore.QModelIndex

Return type:

str

Returns the name of the item stored in the model under the index given.

PySide2.QtWidgets.QDirModel.filePath(index)
Parameters:

index – PySide2.QtCore.QModelIndex

Return type:

str

Returns the path of the item stored in the model under the index given.

PySide2.QtWidgets.QDirModel.filter()
Return type:

Filters

Returns the filter specification for the directory model.

setFilter() Filters

PySide2.QtWidgets.QDirModel.iconProvider()
Return type:

PySide2.QtWidgets.QFileIconProvider

Returns the file icon provider for this directory model.

See also

setIconProvider()

PySide2.QtWidgets.QDirModel.index(path[, column=0])
Parameters:

  • path – str

  • column – int

Return type:

PySide2.QtCore.QModelIndex

This is an overloaded function.

Returns the model item index for the given path .

PySide2.QtWidgets.QDirModel.isDir(index)
Parameters:

index – PySide2.QtCore.QModelIndex

Return type:

bool

Returns true if the model item index represents a directory; otherwise returns false .

PySide2.QtWidgets.QDirModel.isReadOnly()
Return type:

bool

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

PySide2.QtWidgets.QDirModel.lazyChildCount()
Return type:

bool

This property holds Whether the directory model optimizes the hasChildren function to only check if the item is a directory..

If this property is set to false, the directory model will make sure that a directory actually containes any files before reporting that it has children. Otherwise the directory model will report that an item has children if the item is a directory.

This property is false by default

PySide2.QtWidgets.QDirModel.mkdir(parent, name)
Parameters:
Return type:

PySide2.QtCore.QModelIndex

Create a directory with the name in the parent model item.

PySide2.QtWidgets.QDirModel.nameFilters()
Return type:

list of strings

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

setNameFilters()

PySide2.QtWidgets.QDirModel.refresh([parent=QModelIndex()])
Parameters:

parent – PySide2.QtCore.QModelIndex

QDirModel caches file information. This function updates the cache. The parent parameter is the directory from which the model is updated; the default value will update the model from root directory of the file system (the entire model).

PySide2.QtWidgets.QDirModel.remove(index)
Parameters:

index – PySide2.QtCore.QModelIndex

Return type:

bool

Removes the model item index from the directory 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()

Return type:

bool

This property holds Whether the directory model should resolve symbolic links.

This is only relevant on operating systems that support symbolic links.

PySide2.QtWidgets.QDirModel.rmdir(index)
Parameters:

index – PySide2.QtCore.QModelIndex

Return type:

bool

Removes the directory corresponding to the model item index in the directory 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.

remove()

PySide2.QtWidgets.QDirModel.setFilter(filters)
Parameters:

filters – Filters

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

Note that the filter you set should always include the AllDirs enum value, otherwise QDirModel won’t be able to read the directory structure.

filter() Filters

PySide2.QtWidgets.QDirModel.setIconProvider(provider)
Parameters:

provider – PySide2.QtWidgets.QFileIconProvider

Sets the provider of file icons for the directory model.

See also

iconProvider()

PySide2.QtWidgets.QDirModel.setLazyChildCount(enable)
Parameters:

enable – bool

This property holds Whether the directory model optimizes the hasChildren function to only check if the item is a directory..

If this property is set to false, the directory model will make sure that a directory actually containes any files before reporting that it has children. Otherwise the directory model will report that an item has children if the item is a directory.

This property is false by default

PySide2.QtWidgets.QDirModel.setNameFilters(filters)
Parameters:

filters – list of strings

Sets the name filters for the directory model.

See also

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

Parameters:

enable – bool

This property holds Whether the directory model should resolve symbolic links.

This is only relevant on operating systems that support symbolic links.
