Struct gtk4::DirectoryList[−][src]

pub struct DirectoryList(_);

Expand description

DirectoryList is a list model that wraps FileExtManual::enumerate_children_async().

It presents a GListModel and fills it asynchronously with the GFileInfos returned from that function.

Enumeration will start automatically when a the property::DirectoryList::file property is set.

While the DirectoryList is being filled, the property::DirectoryList::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 property::DirectoryList::error property will be set to give more indication about the failure.

The GFileInfos 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.
