    • Method Detail

      • getValueModel

        protected ValueModel<V> getValueModel()
        Returns:
        The value model used by this component.
      • determineValid

        protected boolean determineValid()
        Checks the state of the component for validity. This version returns true.

        This version performs no additional checks if the control is disabled.

        Overrides:
        determineValid in class AbstractComponent
        Returns:
        true if the component and all children passes all validity tests, else false.
      • validate

        public boolean validate()
        Validates the user input of this component and all child components. The component will be updated with error information.

        This version clears all notifications. This version calls AbstractComponent.updateValid().

        This version validates the associated value model. This version performs no additional checks if the control is disabled.

        Specified by:
        validate in interface Component
        Overrides:
        validate in class AbstractComponent
        Returns:
        The current state of Component.isValid() as a convenience.
      • reset

        public void reset()
        Resets the control to its default value.

        This version clears any notification.

        This version resets the control value.

        Specified by:
        reset in interface Control
        Overrides:
        reset in class AbstractControl
        See Also:
        resetValue()
      • getValue

        public V getValue()
        Specified by:
        getValue in interface com.globalmentor.model.Valued<V>
        Specified by:
        getValue in interface ValuedComponent<V>
        Specified by:
        getValue in interface ValueModel<V>
        Returns:
        The input value, or null if there is no input value.
      • setValue

        public void setValue​(V newValue)
                      throws java.beans.PropertyVetoException
        Description copied from interface: ValueModel
        Sets the new value. This is a bound property that only fires a change event when the new value is different via the equals() method. If a validator is installed, the value will first be validated before the current value is changed. Validation always occurs if a validator is installed, even if the value is not changing. If the value change is vetoed by the installed validator, the validation exception will be accessible via Throwable.getCause().
        Specified by:
        setValue in interface com.globalmentor.model.MutableValued<V>
        Specified by:
        setValue in interface ValuedComponent<V>
        Specified by:
        setValue in interface ValueModel<V>
        Parameters:
        newValue - The new value.
        Throws:
        java.beans.PropertyVetoException - if the provided value is not valid or the change has otherwise been vetoed.

      • clearValue

        public void clearValue()
        Description copied from interface: ValueModel
        Clears the value by setting the value to null, which may be invalid according to any installed validators. No validation occurs.
