An example GtkActionBar

It is expected to be displayed below the content and expand horizontally to fill the area.

It allows placing children at the start or the end. In addition, it contains an internal centered box which is centered with respect to the full width of the box, even if the children at either side take up different amounts of space.

CSS nodes

ActionBar has a single CSS node with name actionbar.

the center Widget or None.

Gets whether the contents of the action bar are revealed.

Returns

the current value of the property::ActionBar::revealed property.
