Struct libadwaita::OverlaySplitView

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

A widget presenting sidebar and content side by side or as an overlay.

overlay-split-view overlay-split-view-collapsed

OverlaySplitView has two children: sidebar and content, and displays them side by side.

When collapsed is set to TRUE, the sidebar is instead shown as an overlay above the content widget.

The sidebar can be hidden or shown using the show-sidebar property.

Sidebar can be displayed before or after the content, this can be controlled with the sidebar-position property.

Collapsing the split view automatically hides the sidebar widget, and uncollapsing it shows the sidebar. If this behavior is not desired, the pin-sidebar property can be used to override it.

OverlaySplitView supports an edge swipe gesture for showing the sidebar, and a swipe from the sidebar for hiding it. Gestures are only supported on touchscreen, but not touchpad. Gestures can be controlled with the enable-show-gesture and enable-hide-gesture properties.

See also NavigationSplitView.

OverlaySplitView is typically used together with an Breakpoint setting the collapsed property to TRUE on small widths, as follows:

<object class="AdwWindow">
  <property name="default-width">800</property>
  <property name="default-height">800</property>
  <child>
    <object class="AdwBreakpoint">
      <condition>max-width: 400sp</condition>
      <setter object="split_view" property="collapsed">True</setter>
    </object>
  </child>
  <property name="content">
    <object class="AdwOverlaySplitView" id="split_view">
      <property name="sidebar">
        <!-- ... -->
      </property>
      <property name="content">
        <!-- ... -->
      </property>
    </object>
  </property>
</object>

OverlaySplitView is often used for implementing the utility pane pattern.

§Sizing

When not collapsed, OverlaySplitView changes the sidebar width depending on its own width.

If possible, it tries to allocate a fraction of the total width, controlled with the sidebar-width-fraction property.

The sidebar also has minimum and maximum sizes, controlled with the min-sidebar-width and max-sidebar-width properties.

The minimum and maximum sizes are using the length unit specified with the sidebar-width-unit.

By default, sidebar is using 25% of the total width, with 180sp as the minimum size and 280sp as the maximum size.

When collapsed, the preferred width fraction is ignored and the sidebar uses max-sidebar-width when possible.

§Header Bar Integration

When used inside OverlaySplitView, HeaderBar will automatically hide the window buttons in the middle.

§OverlaySplitView as gtk::Buildable

The OverlaySplitView implementation of the gtk::Buildable interface supports setting the sidebar widget by specifying “sidebar” as the “type” attribute of a <child> element, Specifying “content” child type or omitting it results in setting the content widget.

§CSS nodes

OverlaySplitView has a single CSS node with the name overlay-split-view.

It contains two nodes with the name widget, containing the sidebar and content children.

When not collapsed, they have the .sidebar-view and .content-view style classes respectively.

overlay-split-view
├── widget.sidebar-pane
│   ╰── [sidebar child]
╰── widget.content-pane
    ╰── [content child]

When collapsed, the one containing the sidebar child has the .background style class and the other one has no style classes.

overlay-split-view
├── widget.background
│   ╰── [sidebar child]
╰── widget
    ╰── [content child]

§Accessibility

OverlaySplitView uses the GTK_ACCESSIBLE_ROLE_GROUP role.
