  • Constructor Details

    • QShortProperty

      public QShortProperty()
      Constructs a short-typed property.

    • QShortProperty

      public QShortProperty(short initialValue)
      Constructs a short-typed property with the provided initialValue.
      Parameters:
      initialValue -

    • QShortProperty

      public QShortProperty(QShortPropertyBinding binding)
      Constructs a short-typed property with the provided binding.
      Parameters:
      binding -

    • QShortProperty

      public QShortProperty(QPropertyBinding<@QtPrimitiveType Short> binding)
      Constructs a short-typed property with the provided binding.
      Parameters:
      binding -

    • QShortProperty

      public QShortProperty(QtUtilities.ShortSupplier functor)

      Constructs a short-typed property bound to the provided functor.

      Parameters:
      functor -

  • Method Details

    • value

      @QtUninvokable public short value()
      Returns the value of the property. This may evaluate a binding expression that is tied to this property, before returning the value.
      Returns:
      value

    • setValue

      @QtUninvokable public void setValue(short newValue)

      Assigns newValue to this property and removes the property's associated binding, if present.

      Parameters:
      newValue -

    • setBinding

      @QtUninvokable public QShortPropertyBinding setBinding(QtUtilities.ShortSupplier functor)

      Associates the value of this property with the provided newBinding expression and returns the previously associated binding.

      The first time the property value is read, the binding is evaluated. Whenever a dependency of the binding changes, the binding will be re-evaluated the next time the value of this property is read.

      Parameters:
      newBinding -
      Returns:
      oldBinding

    • setBinding

      @QtUninvokable public QShortPropertyBinding setBinding(QShortPropertyBinding newBinding)

      Associates the value of this property with the provided newBinding expression and returns the previously associated binding.

      The binding's value type (QUntypedPropertyBinding.valueMetaType()) has to be short, otherwise the property remains unchanged.

      The first time the property value is read, the binding is evaluated. Whenever a dependency of the binding changes, the binding will be re-evaluated the next time the value of this property is read.

      Parameters:
      newBinding -
      Returns:
      oldBinding

    • setBinding

      @QtUninvokable public QShortPropertyBinding setBinding(QPropertyBinding<@QtPrimitiveType Short> newBinding)

      Associates the value of this property with the provided newBinding expression and returns the previously associated binding.

      The binding's value type (QUntypedPropertyBinding.valueMetaType()) has to be short, otherwise the property remains unchanged.

      The first time the property value is read, the binding is evaluated. Whenever a dependency of the binding changes, the binding will be re-evaluated the next time the value of this property is read.

      Parameters:
      newBinding -
      Returns:
      oldBinding

    • setBinding

      @QtUninvokable public boolean setBinding(QUntypedPropertyBinding newBinding)

      Associates the value of this property with the provided newBinding expression.

      The binding's value type (QUntypedPropertyBinding.valueMetaType()) has to be short, otherwise the property remains unchanged and the method returns false.

      The first time the property value is read, the binding is evaluated. Whenever a dependency of the binding changes, the binding will be re-evaluated the next time the value of this property is read.

      Returns true if the type of this property is the same as the type the binding function returns; false otherwise.

      Parameters:
      newBinding -
      Returns:
      true if types match, false otherwise.

    • hasBinding

      @QtUninvokable public boolean hasBinding()
      Checks if the property has a binding.
      Returns:
      true if the property has a binding, false otherwise.

    • binding

      @QtUninvokable public QShortPropertyBinding binding()
      Returns the binding expression that is associated with this property. A default constructed QShortPropertyBinding will be returned if no such association exists.
      Returns:
      binding

    • takeBinding

      @QtUninvokable public QShortPropertyBinding takeBinding()

      Disassociates the binding expression from this property and returns it.

      After calling this function, the value of the property will only change if you assign a new value to it, or when a new binding is set.

      Returns:
      the removed binding

    • onValueChanged

      @QtUninvokable public 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
      See Also:

    • subscribe

      @QtUninvokable public 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
      See Also:

    • addNotifier

      @QtUninvokable public QPropertyNotifier addNotifier(Runnable f)

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

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

      Parameters:
      f -
      Returns:
      property notifier

    • notifyProperty

      @QtUninvokable public final void notifyProperty()
