Struct NavigationPage

source
pub struct NavigationPage { /* private fields */ }
Available on crate feature v1_4 only.
Expand description

A page within NavigationView or NavigationSplitView.

Each page has a child widget, a title and optionally a tag.

The showing, shown, hiding and hidden signals can be used to track the page’s visibility within its NavigationView.

§Header Bar Integration

When placed inside NavigationPage, HeaderBar will display the page title instead of window title.

When used together with NavigationView, it will also display a back button that can be used to go back to the previous page. Set show-back-button to FALSE to disable that behavior if it’s unwanted.

§CSS Nodes

NavigationPage has a single CSS node with name navigation-view-page.

§Accessibility

NavigationPage uses the GTK_ACCESSIBLE_ROLE_GROUP role.

§Properties

§can-pop

Whether the page 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.

Readable | Writeable

§child

The child widget.

Readable | Writeable

§tag

The page tag.

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.

Readable | Writeable

§title

The page title.

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.

§Signals

§hidden

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

It will always be preceded by hiding or showing.

§hiding

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

It will always be followed by hidden or shown.

§showing

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

It will always be followed by shown or hidden.

§shown

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

It will always be preceded by showing or hiding.

Widget

§destroy

Signals that all holders of a reference to the widget should release the reference that they hold.

May result in finalization of the widget if all references are released.

This signal is not suitable for saving widget state.

§direction-changed

Emitted when the text direction of a widget changes.

§hide

Emitted when @widget is hidden.

§keynav-failed

Emitted if keyboard navigation fails.

See [WidgetExtManual::keynav_failed()][crate::gtk::prelude::WidgetExtManual::keynav_failed()] for details.

§map

Emitted when @widget is going to be mapped.

A widget is mapped when the widget is visible (which is controlled with visible) and all its parents up to the toplevel widget are also visible.

The ::map signal can be used to determine whether a widget will be drawn, for instance it can resume an animation that was stopped during the emission of unmap.

§mnemonic-activate

Emitted when a widget is activated via a mnemonic.

The default handler for this signal activates @widget if @group_cycling is false, or just makes @widget grab focus if @group_cycling is true.

§move-focus

Emitted when the focus is moved.

The ::move-focus signal is a keybinding signal.

The default bindings for this signal are Tab to move forward, and Shift+Tab to move backward.

Action

§query-tooltip

Emitted when the widget’s tooltip is about to be shown.

This happens when the has-tooltip property is true and the hover timeout has expired with the cursor hovering “above” @widget; or emitted when @widget got focus in keyboard mode.

Using the given coordinates, the signal handler should determine whether a tooltip should be shown for @widget. If this is the case true should be returned, false otherwise. Note that if @keyboard_mode is true, the values of @x and @y are undefined and should not be used.

The signal handler is free to manipulate @tooltip with the therefore destined function calls.

§realize

Emitted when @widget is associated with a GdkSurface.

This means that [WidgetExtManual::realize()][crate::gtk::prelude::WidgetExtManual::realize()] has been called or the widget has been mapped (that is, it is going to be drawn).

§show

Emitted when @widget is shown.

§state-flags-changed

Emitted when the widget state changes.

See [WidgetExtManual::state_flags()][crate::gtk::prelude::WidgetExtManual::state_flags()].

§unmap

Emitted when @widget is going to be unmapped.

A widget is unmapped when either it or any of its parents up to the toplevel widget have been set as hidden.

As ::unmap indicates that a widget will not be shown any longer, it can be used to, for example, stop an animation on the widget.

§unrealize

Emitted when the GdkSurface associated with @widget is destroyed.

This means that [WidgetExtManual::unrealize()][crate::gtk::prelude::WidgetExtManual::unrealize()] has been called or the widget has been unmapped (that is, it is going to be hidden).

§Implements
