Constructors

Constructor	Description
BindingBuilder()	Create a BindingBuilder to construct a GObject property binding.
BindingBuilder(GObject source, String sourceProperty, GObject target, String targetProperty)	Create a BindingBuilder to construct a GObject property binding.

Method Summary

Modifier and Type	Method	Description
BindingBuilder<S,T>	bidirectional()	Bidirectional binding; if either the property of the source or the property of the target changes, the other is updated.
Binding	build()	Create the property binding.
BindingBuilder<S,T>	invertBoolean()	If the two properties being bound are booleans, setting one to true will result in the other being set to false and vice versa.
BindingBuilder<S,T>	source(GObject sourceObject)	Set the source GObject
BindingBuilder<S,T>	sourceProperty(String sourceProperty)	Set the property on the source object to bind
BindingBuilder<S,T>	syncCreate()	Synchronize the values of the source and target properties when creating the binding; the direction of the synchronization is always from the source to the target.
BindingBuilder<S,T>	target(GObject targetObject)	Set the target GObject
BindingBuilder<S,T>	targetProperty(String targetProperty)	the property on target to bind
BindingBuilder<S,T>	transformFrom(@Nullable Function<T,S> transformFrom)	Set the transformation function from the target to this GObject, or null to use the default
BindingBuilder<S,T>	transformTo(@Nullable Function<S,T> transformTo)	Set the transformation function from this GObject to the target, or null to use the default.

BindingBuilder

public BindingBuilder()

Create a BindingBuilder to construct a GObject property binding.

• Binding

BindingBuilder

public BindingBuilder(GObject source,
 String sourceProperty,
 GObject target,
 String targetProperty)

Create a BindingBuilder to construct a GObject property binding.

Parameters:

source - the source GObject

sourceProperty - the property on the source object to bind

target - the target GObject

targetProperty - the property on target to bind

See Also:

• Binding

Method Details

source

public BindingBuilder<S,T> source(GObject sourceObject)

Set the source GObject

sourceProperty

public BindingBuilder<S,T> sourceProperty(String sourceProperty)

Set the property on the source object to bind

target

public BindingBuilder<S,T> target(GObject targetObject)

Set the target GObject

targetProperty

public BindingBuilder<S,T> targetProperty(String targetProperty)

the property on target to bind

bidirectional

public BindingBuilder<S,T> bidirectional()

Bidirectional binding; if either the property of the source or the property of the target changes, the other is updated.

syncCreate

public BindingBuilder<S,T> syncCreate()

Synchronize the values of the source and target properties when creating the binding; the direction of the synchronization is always from the source to the target.

invertBoolean

public BindingBuilder<S,T> invertBoolean()

If the two properties being bound are booleans, setting one to true will result in the other being set to false and vice versa. This flag will only work for boolean properties, and cannot be used when passing custom transformation functions.

transformTo

public BindingBuilder<S,T> transformTo(@Nullable Function<S,T> transformTo)

Set the transformation function from this GObject to the target, or null to use the default.

transformFrom

public BindingBuilder<S,T> transformFrom(@Nullable Function<T,S> transformFrom)

Set the transformation function from the target to this GObject, or null to use the default

build

public Binding build()

Create the property binding.
