DirectoryList#

class DirectoryList(**properties: Any)#

Superclasses: Object

Implemented Interfaces: ListModel

GtkDirectoryList is a list model that wraps enumerate_children_async().

It presents a GListModel and fills it asynchronously with the GFileInfo’s returned from that function.

Enumeration will start automatically when the file property is set.

While the GtkDirectoryList is being filled, the loading property will be set to True. You can listen to that property if you want to show information like a GtkSpinner or a “Loading…” text.

If loading fails at any point, the error property will be set to give more indication about the failure.

The GFileInfo’s returned from a GtkDirectoryList have the “standard::file” attribute set to the GFile they refer to. This way you can get at the file that is referred to in the same way you would via get_child(). This means you do not need access to the GtkDirectoryList, but can access the GFile directly from the GFileInfo when operating with a GtkListView or similar.

Constructors#

class DirectoryList

classmethod new(attributes: str | None = None, file: File | None = None) → DirectoryList#

Creates a new GtkDirectoryList.

The GtkDirectoryList is querying the given file with the given attributes.

Parameters:

attributes – The attributes to query with
file – The file to query

Methods#

class DirectoryList

get_attributes() → str | None#: Gets the attributes queried on the children.

get_error() → GError | None#

Gets the loading error, if any.

If an error occurs during the loading process, the loading process will finish and this property allows querying the error that happened. This error will persist until a file is loaded again.

An error being set does not mean that no files were loaded, and all successfully queried files will remain in the list.

get_file() → File | None#: Gets the file whose children are currently enumerated.

get_io_priority() → int#: Gets the IO priority set via set_io_priority().

get_monitored() → bool#: Returns whether the directory list is monitoring the directory for changes.

is_loading() → bool#

Returns True if the children enumeration is currently in progress.

Files will be added to self from time to time while loading is going on. The order in which are added is undefined and may change in between runs.

set_attributes(attributes: str | None = None) → None#

Sets the attributes to be enumerated and starts the enumeration.

If attributes is None, the list of file infos will still be created, it will just not contain any extra attributes.

Parameters:: attributes – the attributes to enumerate

set_file(file: File | None = None) → None#

Sets the file to be enumerated and starts the enumeration.

If file is None, the result will be an empty list.

Parameters:: file – the GFile to be enumerated

set_io_priority(io_priority: int) → None#

Sets the IO priority to use while loading directories.

Setting the priority while self is loading will reprioritize the ongoing load as soon as possible.

The default IO priority is %G_PRIORITY_DEFAULT, which is higher than the GTK redraw priority. If you are loading a lot of directories in parallel, lowering it to something like %G_PRIORITY_DEFAULT_IDLE may increase responsiveness.

Parameters:: io_priority – IO priority to use

set_monitored(monitored: bool) → None#

Sets whether the directory list will monitor the directory for changes.

If monitoring is enabled, the ::items-changed signal will be emitted when the directory contents change.

When monitoring is turned on after the initial creation of the directory list, the directory is reloaded to avoid missing files that appeared between the initial loading and when monitoring was turned on.

Parameters:: monitored – True to monitor the directory for changes
