    • Method Detail

      • getPredefinedProps

        public void getPredefinedProps()
        Gets potential references to predefined properties for this container. This method is called once just after cloning of the property container.

        The method should get reference to using the getProp(...) methods. This allows the subclass to be able to retrieve the new instances to the properties created during addPredefinedProps() if stored in instance variables.

        Subclasses must override this method to do the appropriate initialization, as this method does nothing for the PropCnr class implementation.

        Overrides:
        getPredefinedProps in class UIContainer

      • clone

        public UISwapContainer clone()
        Creates a clone out of this property. The cloning is overridden by the subclasses in order to handle cloning of its class variables appropriately.

        Cloning is used for "virtualization" of a property tree in the server. Client property classes will therefore throw CloneNotSupportedException.

        Once a tree has been cloned, the change-flag is reset, and the create-flag is set. All listeners are also removed! The new cloned property is an orphan, i.e. has no parent set. All children properties are also (deep) cloned.

        Note that the cloning process is done WITHOUT thread synchronization for performance reasons, thus no modifications should be done to the tree!

        Overrides:
        clone in class UIContainer

        public boolean mustHaveExplicitWidth()
        Does this component require an explicitly defined width?
        Overrides:

        public boolean hasImplicitAlignFillY()
        Returns if the component has implicit component vertical fill.
        Overrides:

      • isSelected

        public boolean isSelected()

        For a multiple-selection capable component, this indicates any selection, i.e. true is returned as soon as at least one element is selected, false for none.

        The checkbox for example has two "selected states": checked and third state: in this case, true is returned for the third state as well as the checked state.

        Specified by:

        Default type is SLIDE.

        Parameters:
        type - The transition type.
        Returns:
        true if animation type was changed, false for no change.

      • setTransition

        public boolean setTransition​(int dir)
        Sets the animation transition direction to use from now on when a view is changed or swapped programmatically or through a focus change.
        Parameters:
        dir - The transition direction. If 1, transition forward. If 0, automatic transition forward or backward depending on view ordering when switching, If -1, transition backward. For example, the slide transition slides the view from right to left when dir == 1, and from left to right when dir == -1.
        Returns:
        true if animation direction was changed, false for no change.
        Throws:
        java.lang.IllegalArgumentException - If dir is not -1, 0 or 1.

        Sets the focus to the UI container and all its parents. This method is called when focus is to be set to a component, making it possible for containers such as accordion/swap/tab to change its main container into view.

        Subclasses must override this method to process it, but make sure to call super.setUIContainerFocus(requestor) first!

        Specified by:
        setUIContainerFocus in interface IUIComp
        Overrides:
        setUIContainerFocus in class UIContainer
        Parameters:
        requestor - The requestor is a child to this container.
        doAnimate - Flag to enable animation when selection is changed for e.g. accordion, swap or tab containers.

        public void onUISelection(UISelectionEvent event)

        Specified by:
        getOnUISelectionMethod in interface IUISelectionComp
        Returns:
        The method, or null if none is registered.
