Constructor Details

QComputedFloatProperty

public QComputedFloatProperty(QtUtilities.FloatSupplier getter)

Constructs a float-typed computed-value property according to the given value supplier.

Parameters:

getter - supplying the computed value

Method Details

value

@QtUninvokable public float value()

Returns the value of the property computed by the given getter.

Returns:

value

valueMetaType

@QtUninvokable public final QMetaType valueMetaType()

hasBinding

@QtUninvokable public final boolean hasBinding()

onValueChanged

@QtUninvokable public final QPropertyChangeHandler onValueChanged(Runnable f)

Registers the given functor f as a callback that shall be called whenever the value of the property changes.

The returned property change handler object keeps track of the registration. As long as the change handler is alive i.e. as long as a reference to the QPropertyChangeHandler instance exists, the callback remains installed. When the garbage collection deletes the instance, the callback is de-registered.

Parameters:

f -

Returns:

property change handler

QPropertyChangeHandler

subscribe

@QtUninvokable public final QPropertyChangeHandler subscribe(Runnable f)

Subscribes the given functor f as a callback that is called immediately and whenever the value of the property changes in the future.

Parameters:

f -

Returns:

property change handler
