#[repr(transparent)]pub struct ListItem { /* private fields */ }
Expand description
ListItem
is used by list widgets to represent items in a GListModel
.
The ListItem
s are managed by the list widget (with its factory)
and cannot be created by applications, but they need to be populated
by application code. This is done by calling set_child()
.
ListItem
s exist in 2 stages:
-
The unbound stage where the listitem is not currently connected to an item in the list. In that case, the
item
property is set toNone
. -
The bound stage where the listitem references an item from the list. The
item
property is notNone
.
Properties
activatable
If the item can be activated by the user.
Readable | Writeable
child
Widget used for display.
Readable | Writeable
item
Displayed item.
Readable
position
Position of the item.
Readable
selectable
If the item can be selected by the user.
Readable | Writeable
selected
If the item is currently selected.

Implementations§
source§impl ListItem
impl ListItem
sourcepub fn is_activatable(&self) -> bool
pub fn is_activatable(&self) -> bool
sourcepub fn position(&self) -> u32
pub fn position(&self) -> u32
Gets the position in the model that @self currently displays.
If @self is unbound, GTK_INVALID_LIST_POSITION
is returned.
Returns
The position of this item
sourcepub fn is_selectable(&self) -> bool
pub fn is_selectable(&self) -> bool
Checks if a list item has been set to be selectable via gtk_list_item_set_selectable().
Do not confuse this function with is_selected()
.
Returns
true
if the item is selectable
sourcepub fn is_selected(&self) -> bool
pub fn is_selected(&self) -> bool
sourcepub fn set_activatable(&self, activatable: bool)
pub fn set_activatable(&self, activatable: bool)
Sets @self to be activatable.
If an item is activatable, double-clicking on the item, using
the Return key or calling gtk_widget_activate() will activate
the item. Activating instructs the containing view to handle
activation. ListView
for example will be emitting the
activate
signal.
By default, list items are activatable.
activatable
if the item should be activatable
sourcepub fn set_selectable(&self, selectable: bool)
pub fn set_selectable(&self, selectable: bool)
Sets @self to be selectable.
If an item is selectable, clicking on the item or using the keyboard will try to select or unselect the item. If this succeeds is up to the model to determine, as it is managing the selected state.
Note that this means that making an item non-selectable has no influence on the selected state at all. A non-selectable item may still be selected.
By default, list items are selectable. When rebinding them to a new item, they will also be reset to be selectable by GTK.
selectable
if the item should be selectable
