Builder

protected Builder()

Default constructor for a Builder object.

Method Details

build

public SignalGroup build()

Finish building the SignalGroup object. This will call GObject.withProperties(org.gnome.glib.Type, java.lang.String[], org.gnome.gobject.Value[]) to create a new GObject instance, which is then cast to SignalGroup.

Overrides:

build in class GObject.Builder<B extends SignalGroup.Builder<B>>

Returns:

a new instance of SignalGroup with the properties that were set in the Builder object.

setTarget

public B setTarget(GObject target)

The target instance used when connecting signals.

Parameters:

target - the value for the target property

Returns:

the Builder instance is returned, to allow method chaining

setTargetType

public B setTargetType(Type targetType)

The GType of the target property.

Parameters:

targetType - the value for the target-type property

Returns:

the Builder instance is returned, to allow method chaining

onBind

public B onBind(SignalGroup.BindCallback handler)

This signal is emitted when GSignalGroup:target is set to a new value other than null. It is similar to GObject::notify on target except it will not emit when GSignalGroup:target is null and also allows for receiving the GObject without a data-race.

Parameters:

handler - the signal handler

Returns:

the Builder instance is returned, to allow method chaining

See Also:

• SignalGroup.BindCallback.run(org.gnome.gobject.GObject)

onUnbind

public B onUnbind(SignalGroup.UnbindCallback handler)

This signal is emitted when the target instance of self is set to a new GObject.

This signal will only be emitted if the previous target of self is non-null.

Parameters:

handler - the signal handler

Returns:

the Builder instance is returned, to allow method chaining
