Struct gtk4::ActionBar

source ·
#[repr(transparent)]
pub struct ActionBar { /* private fields */ }
Expand description

ActionBar is designed to present contextual actions.

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.

GtkActionBar as GtkBuildable

The ActionBar implementation of the Buildable interface supports adding children at the start or end sides by specifying “start” or “end” as the “type” attribute of a <child> element, or setting the center widget by specifying “center” value.

CSS nodes

actionbar
╰── revealer
    ╰── box
        ├── box.start
        │   ╰── [start children]
        ├── [center widget]
        ╰── box.end
            ╰── [end children]

A ActionBar’s CSS node is called actionbar. It contains a revealer subnode, which contains a box subnode, which contains two box subnodes at the start and end of the action bar, with start and `end style classes respectively, as well as a center node that represents the center child.

Each of the boxes contains children packed for that side.

Implementations§

Creates a new ActionBar widget.

Returns

a new ActionBar

Creates a new builder-pattern struct instance to construct ActionBar objects.

This method returns an instance of ActionBarBuilder which can be used to create ActionBar objects.

Retrieves the center bar widget of the bar.

Returns

the center Widget

Gets whether the contents of the action bar are revealed.

Returns

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

Adds @child to @self, packed with reference to the end of the @self.

child

the Widget to be added to @self

Adds @child to @self, packed with reference to the start of the @self.

child

the Widget to be added to @self

Removes a child from @self.

child

the Widget to be removed

Sets the center widget for the ActionBar.

center_widget

a widget to use for the center

Reveals or conceals the content of the action bar.

Note: this does not show or hide @self in the property::Widget::visible sense, so revealing has no effect if the action bar is hidden.

revealed

The new value of the property
