Struct libadwaita::ToolbarView

pub struct ToolbarView { /* private fields */ }

Available on crate feature v1_4 only.

A widget containing a page, as well as top and/or bottom bars.

ToolbarView has a single content widget and one or multiple top and bottom bars, shown at the top and bottom sides respectively.

Example of an ToolbarView UI definition:

<object class="AdwToolbarView">
  <child type="top">
    <object class="AdwHeaderBar"/>
  </child>
  <property name="content">
    <object class="AdwPreferencesPage">
      <!-- ... -->
    </object>
  </property>
</object>

The following kinds of top and bottom bars are supported:

• HeaderBar
• TabBar
• ViewSwitcherBar
• Gtk::ActionBar
• gtk::HeaderBar
• Gtk::PopoverMenuBar
• Gtk::SearchBar
• Any Gtk::Box or a similar widget with the .toolbar style class

By default, top and bottom bars are flat and scrolling content has a subtle undershoot shadow, same as when using the .undershoot-top and .undershoot-bottom style classes. This works well in most cases, e.g. with StatusPage or PreferencesPage, where the background at the top and bottom parts of the page is uniform. Additionally, windows with sidebars should always use this style.

top-bar-style and bottom-bar-style properties can be used add an opaque background and a persistent shadow to top and bottom bars, this can be useful for content such as utility panes, where some elements are adjacent to the top/bottom bars, or TabView, where each page can have a different background.

ToolbarView ensures the top and bottom bars have consistent backdrop styles and vertical spacing. For comparison:

Any top and bottom bars can also be dragged to move the window, equivalent to putting them into a Gtk::WindowHandle.

Content is typically place between top and bottom bars, but can also extend behind them. This is controlled with the extend-content-to-top-edge and extend-content-to-bottom-edge properties.

Top and bottom bars can be hidden and revealed with an animation using the reveal-top-bars and reveal-bottom-bars properties.

ToolbarView as gtk::Buildable

The ToolbarView implementation of the gtk::Buildable interface supports adding a top bar by specifying “top” as the “type” attribute of a <child> element, or adding a bottom bar by specifying “bottom”.

Accessibility

ToolbarView uses the GTK_ACCESSIBLE_ROLE_GROUP role.

Properties

bottom-bar-height

The current bottom bar height.

Bottom bar height does change depending on reveal-bottom-bars, including during the transition.

See top-bar-height.

Readable

bottom-bar-style

Appearance of the bottom bars.

If set to ADW_TOOLBAR_FLAT, bottom bars are flat and scrolling content has a subtle undershoot shadow when touching them, same as the .undershoot-bottom style class. This works well for simple content, e.g. StatusPage or PreferencesPage, where the background at the bottom of the page is uniform. Additionally, windows with sidebars should always use this style.

Undershoot shadow is only present if a bottom bar is actually present and visible. It is also never present if extend-content-to-bottom-edge is set to TRUE.

If set to ADW_TOOLBAR_RAISED, bottom bars have an opaque background and a persistent shadow, this is suitable for content such as utility panes, where some elements are directly adjacent to the bottom bars, or TabView, where each page can have a different background.

ADW_TOOLBAR_RAISED_BORDER is similar to ADW_TOOLBAR_RAISED, but the shadow is replaced with a more subtle border. This can be useful for applications like image viewers.
