class SetProperty[E]class ReadOnlySetWrapper[E]
Members list
Value members
Concrete methods
Creates a content binding between the ObservableSet, that is wrapped in this ReadOnlySetProperty, and another ObservableSet.
Creates a content binding between the ObservableSet, that is wrapped in this ReadOnlySetProperty, and another ObservableSet.
A content binding ensures that the content of the wrapped ObservableSets is the same as that of the other set. If the content of the other set changes, the wrapped set will be updated automatically. Once the wrapped set is bound to another set, you must not change it directly.
Value parameters
- set
-
the ObservableSet this property should be bound to
Attributes
Creates a bidirectional content binding of the ObservableSet, that is wrapped in this ReadOnlySetProperty, and another ObservableSet.
Creates a bidirectional content binding of the ObservableSet, that is wrapped in this ReadOnlySetProperty, and another ObservableSet.
A bidirectional content binding ensures that the content of two ObservableSets is the same. If the content of one of the sets changes, the other one will be updated automatically.
Value parameters
- set
-
the ObservableSet this property should be bound to
Attributes
Deletes a content binding between the ObservableSet, that is wrapped in this ReadOnlySetProperty, and another Object.
Deletes a content binding between the ObservableSet, that is wrapped in this ReadOnlySetProperty, and another Object.
This is a helper method that calls the JavaFX counterpart with a delegate rather than the original object.
Value parameters
- sfx
-
the SFXDelegate object to which the binding should be removed

SFXDelegate -> Any
- Inherited from:
- SFXDelegate
Returns an ObservableValue
that holds this value and is updated only when condition
holds true
.
Returns an ObservableValue
that holds this value and is updated only when condition
holds true
.
The returned ObservableValue
only observes this value when condition
holds true
. This allows this ObservableValue
and the conditional ObservableValue
to be garbage collected if neither is otherwise strongly referenced when condition
holds false
. This is in contrast to the general behavior of bindings, where the binding is only eligible for garbage collection when not observed itself.
A condition
holding null
is treated as holding false
.
For example:
val condition = BooleanProperty(true)
val longLivedProperty = StringProperty("A")
val whenProperty = longLivedProperty.when(condition)
// observe whenProperty, which will in turn observe longLivedProperty
whenProperty.onChange((_, old, current) => println(s"whenProperty change : $old -> $current"));
longLivedProperty.value = "B" // "B" is printed
condition.value = false
// After condition becomes false, whenProperty stops observing longLivedProperty; condition
// and whenProperty may now be eligible for GC despite being observed by the ChangeListener
longLivedProperty.value = "C" // nothing is printed
longLivedProperty.value = "D" // nothing is printed
condition.value = true // longLivedProperty is observed again, and "D" is printed
Value parameters
