Expand description

Trait containing all ListBoxRow methods.

§Implementors

ListBoxRow

Provided Methods§

Source

fn changed(&self)

t fully control the data model you have to duplicate the data that affects the listbox row functions into the row widgets themselves. Another alternative is to call ListBox::invalidate_sort() on any model change, but that is more expensive.

Source

fn is_activatable(&self) -> bool

Gets whether the row is activatable.

§Returns

true if the row is activatable

Source

fn child(&self) -> Option<Widget>

Gets the child widget of @self.

§Returns

the child widget of @self

Source

fn header(&self) -> Option<Widget>

Returns the current header of the @self.

This can be used in a `callback::Gtk::ListBoxUpdateHeaderFunc to see if there is a header set already, and if so to update the state of it.

§Returns

the current header

Source

fn index(&self) -> i32

Gets the current index of the @self in its ListBox container.

§Returns

the index of the @self, or -1 if the @self is not in a listbox

Source

fn is_selectable(&self) -> bool

Gets whether the row can be selected.

§Returns

true if the row is selectable

Source

fn is_selected(&self) -> bool

Returns whether the child is currently selected in its ListBox container.

§Returns

true if @self is selected

Source

fn set_activatable(&self, activatable: bool)

Set whether the row is activatable.

§activatable

true to mark the row as activatable

Source

fn set_child(&self, child: Option<&impl IsA<Widget>>)

Sets the child widget of @self_.

§child

the child widget

Source

fn set_header(&self, header: Option<&impl IsA<Widget>>)

Sets the current header of the @self.

This is only allowed to be called from a `callback::Gtk::ListBoxUpdateHeaderFunc. It will replace any existing header in the row, and be shown in front of the row in the listbox.

the header

Source

fn set_selectable(&self, selectable: bool)

Set whether the row can be selected.

§selectable

true to mark the row as selectable

Source

fn connect_activate<F: Fn(&Self) + 'static>(&self, f: F) -> SignalHandlerId

s parent ListBox.

Source

fn emit_activate(&self)

Source

fn connect_activatable_notify<F: Fn(&Self) + 'static>( &self, f: F, ) -> SignalHandlerId

Source

fn connect_child_notify<F: Fn(&Self) + 'static>(&self, f: F) -> SignalHandlerId

Source

fn connect_selectable_notify<F: Fn(&Self) + 'static>( &self, f: F, ) -> SignalHandlerId

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
