Struct gtk4::SingleSelection
source · #[repr(transparent)]pub struct SingleSelection { /* private fields */ }
Expand description
SingleSelection
is a SelectionModel
that allows selecting a single
item.
Note that the selection is persistent – if the selected item is removed
and re-added in the same items-changed
emission, it
stays selected. In particular, this means that changing the sort order of an
underlying sort model will preserve the selection.
Properties
autoselect
If the selection will always select an item.
Readable | Writeable
can-unselect
If unselecting the selected item is allowed.
Readable | Writeable
item-type
The type of items. See [ListModelExtManual::item_type()
][crate::gio::prelude::ListModelExtManual::item_type()].
Readable
model
The model being managed.
Readable | Writeable
n-items
The number of items. See [ListModelExtManual::n_items()
][crate::gio::prelude::ListModelExtManual::n_items()].
Readable
selected
Position of the selected item.
Readable | Writeable
selected-item
The selected item.

Implementations§
source§impl SingleSelection
impl SingleSelection
sourcepub fn new(model: Option<impl IsA<ListModel>>) -> SingleSelection
pub fn new(model: Option<impl IsA<ListModel>>) -> SingleSelection
Creates a new selection to handle @model.
model
the GListModel
to manage
Returns
a new SingleSelection
sourcepub fn builder() -> SingleSelectionBuilder
pub fn builder() -> SingleSelectionBuilder
Creates a new builder-pattern struct instance to construct SingleSelection
objects.
This method returns an instance of SingleSelectionBuilder
which can be used to create SingleSelection
objects.
sourcepub fn is_autoselect(&self) -> bool
pub fn is_autoselect(&self) -> bool
sourcepub fn can_unselect(&self) -> bool
pub fn can_unselect(&self) -> bool
sourcepub fn selected(&self) -> u32
pub fn selected(&self) -> u32
Gets the position of the selected item.
If no item is selected, GTK_INVALID_LIST_POSITION
is returned.
Returns
The position of the selected item
sourcepub fn selected_item(&self) -> Option<Object>
pub fn selected_item(&self) -> Option<Object>
sourcepub fn set_autoselect(&self, autoselect: bool)
pub fn set_autoselect(&self, autoselect: bool)
Enables or disables autoselect.
If @autoselect is true
, @self will enforce that an item is always
selected. It will select a new item when the currently selected
item is deleted and it will disallow unselecting the current item.
autoselect
true
to always select an item
sourcepub fn set_can_unselect(&self, can_unselect: bool)
pub fn set_can_unselect(&self, can_unselect: bool)
If true
, unselecting the current item via
gtk_selection_model_unselect_item() is supported.
Note that setting autoselect
will
cause unselecting to not work, so it practically makes no sense
to set both at the same time the same time.
can_unselect
true
to allow unselecting
sourcepub fn set_selected(&self, position: u32)
pub fn set_selected(&self, position: u32)
Selects the item at the given position.
If the list does not have an item at @position or
GTK_INVALID_LIST_POSITION
is given, the behavior depends on the
value of the autoselect
property:
If it is set, no change will occur and the old item will stay
selected. If it is unset, the selection will be unset and no item
will be selected.
position
the item to select or GTK_INVALID_LIST_POSITION
