Trait containing all NavigationPage methods.

NavigationPage

Provided Methods

fn can_pop(&self) -> bool

Gets whether @self can be popped from navigation stack.

Returns

whether the page can be popped from navigation stack

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

Gets the child widget of @self.

Returns

the child widget of @self

fn tag(&self) -> Option<GString>

Gets the tag of @self.

Returns

the page tag

fn title(&self) -> GString

Gets the title of @self.

Returns

the title of @self

fn set_can_pop(&self, can_pop: bool)

Sets whether @self can be popped from navigation stack.

Set it to FALSE to disable shortcuts and gestures, as well as remove the back button from HeaderBar.

Manually calling NavigationView::pop() or using the navigation.pop action will still work.

See show-back-button for removing only the back button, but not shortcuts.

can_pop

whether the page can be popped from navigation stack

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

Sets the child widget of @self.

child

the child widget

fn set_tag(&self, tag: Option<&str>)

Sets the tag for @self.

The tag can be used to retrieve the page with NavigationView::find_page(), as well as with NavigationView::push_by_tag(), NavigationView::pop_to_tag() or NavigationView::replace_with_tags().

Tags must be unique within each NavigationView.

The tag also must be set to use the navigation.push action.

tag

the page tag

fn set_title(&self, title: &str)

Sets the title of @self.

It’s displayed in HeaderBar instead of the window title, and used as the tooltip on the next page’s back button, as well as by screen reader.

title

the title

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

Emitted when the navigation view transition has been completed and the page is fully hidden.

It will always be preceded by hiding or showing.

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

Emitted when the page starts hiding at the beginning of the navigation view transition.

It will always be followed by hidden or shown.

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

Emitted when the page shows at the beginning of the navigation view transition.

It will always be followed by shown or hidden.

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

Emitted when the navigation view transition has been completed and the page is fully shown.

It will always be preceded by showing or hiding.

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

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

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

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