Class ActionBar
- All Implemented Interfaces:
Accessible,Buildable,ConstraintTarget,Proxy
GtkActionBar 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 GtkActionBar implementation of the GtkBuildable 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 GtkActionBar'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.

ActionBar
Create a ActionBar proxy instance for the provided memory address.- Parameters:
address- the memory address of the native object
-
ActionBar
public ActionBar()Creates a new ActionBar.

Method Details
-
getType
-
asParent
Returns this instance as if it were its parent type. This is mostly synonymous to the Javasuperkeyword, but will set the native typeclass function pointers to the parent type. When overriding a native virtual method in Java, "chaining up" withsuper.methodName()doesn't work, because it invokes the overridden function pointer again. To chain up, callasParent().methodName(). This will call the native function pointer of this virtual method in the typeclass of the parent type. -
getCenterWidget
Retrieves the center bar widget of the bar.- Returns:
- the center widget
-
getRevealed
public boolean getRevealed()Gets whether the contents of the action bar are revealed.- Returns:
- the current value of the
Gtk.ActionBar:revealedproperty
-
packEnd
Adds a child to the action bar, packed with reference to the end of the action bar.- Parameters:
child- the widget to be added
-
packStart
Adds a child to the action, packed with reference to the start of the action bar.- Parameters:
child- the widget to be added
-
remove
Removes a child from the action bar.- Parameters:
child- the widget to be removed
-
setCenterWidget
Sets the center widget for the action bar.- Parameters:
centerWidget- a widget to use for the center
-
setRevealed
public void setRevealed(boolean revealed) Reveals or conceals the content of the action bar.Note: this does not show or hide the action bar in the
Gtk.Widget:visiblesense, so revealing has no effect if the action bar is hidden.- Parameters:
revealed- the new value for the property
-
builder
AActionBar.Builderobject constructs aActionBarwith the specified properties. Use the variousset...()methods to set properties, and finish construction withActionBar.Builder.build().- Returns:
- the builder object
