Struct gtk4::DirectoryList
source · #[repr(transparent)]pub struct DirectoryList { /* private fields */ }
Expand description
DirectoryList
is a list model that wraps g_file_enumerate_children_async().
It presents a GListModel
and fills it asynchronously with the GFileInfo
s
returned from that function.
Enumeration will start automatically when a the
file
property is set.
While the DirectoryList
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 Spinner
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 DirectoryList
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 g_file_enumerator_get_child().
This means you do not need access to the DirectoryList
, but can access
the GFile
directly from the GFileInfo
when operating with a ListView
or similar.

Implementations§
source§impl DirectoryList
impl DirectoryList
sourcepub fn new(
attributes: Option<&str>,
file: Option<&impl IsA<File>>
) -> DirectoryList
pub fn new( attributes: Option<&str>, file: Option<&impl IsA<File>> ) -> DirectoryList
Creates a new DirectoryList
.
The DirectoryList
is querying the given @file
with the given @attributes.
attributes
The attributes to query with
file
The file to query
Returns
a new DirectoryList
sourcepub fn attributes(&self) -> Option<GString>
pub fn attributes(&self) -> Option<GString>
sourcepub fn error(&self) -> Option<Error>
pub fn error(&self) -> Option<Error>
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.
Returns
The loading error or None
if
loading finished successfully
sourcepub fn file(&self) -> Option<File>
pub fn file(&self) -> Option<File>
Gets the file whose children are currently enumerated.
Returns
The file whose children are enumerated
sourcepub fn is_monitored(&self) -> bool
pub fn is_monitored(&self) -> bool
sourcepub fn is_loading(&self) -> bool
pub fn is_loading(&self) -> bool
sourcepub fn set_attributes(&self, attributes: Option<&str>)
pub fn set_attributes(&self, attributes: Option<&str>)
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.
attributes
the attributes to enumerate
sourcepub fn set_monitored(&self, monitored: bool)
pub fn set_monitored(&self, monitored: bool)
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.
monitored
true
to monitor the directory for changes

impl DirectoryList
sourcepub fn io_priority(&self) -> Priority
pub fn io_priority(&self) -> Priority
sourcepub fn set_io_priority(&self, io_priority: Priority)
pub fn set_io_priority(&self, io_priority: Priority)
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.
io_priority
IO priority to use
sourcepub fn builder() -> DirectoryListBuilder
pub fn builder() -> DirectoryListBuilder
Creates a new builder-pattern struct instance to construct DirectoryList
objects.
This method returns an instance of DirectoryListBuilder
which can be used to create DirectoryList
objects.
