public interface IUIComp extends IComponent, IVSFieldListener, ICustomDataProvider
The interface for the UIComp class is the basic implementation of a single user interface component.

The component has a data container that is not persistent, i.e. is not written e.g. to disk.

    • canAcceptUIContainerFocus

      String canAcceptUIContainerFocus()
      Returns if this container can accept focus itself or for one of its children components. If this is a component and not a container, this request is redirected to the parent container.

      Typically, a container returns itself as instance if it is disabled or hidden.

      Returns:
      null if this container (or parent container if this is a component) and all containers up to the topmost level returns null, otherwise an error message why the container that did not accept focus.
    • setUIContainerFocus

      String setUIContainerFocus(UIComp requestor, boolean doAnimate)
      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!

      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.
      Returns:
      null for success, otherwise an error message why it failed.
    • setComponentToVSField

      int setComponentToVSField()
      Sets the text or value from this text or value component to its VirtualSpace Field, if any.
      Returns:
      1 for update completed, 0 for nothing done and -1 for error occurred.

    • getErrorMessage

      KString getErrorMessage(ILocaleString localeString, ValueConversionException exception) throws KStringException
      Gets the localized error message for a validation exception.

      Throws:
      KStringException - For exceptions formatting a HTML string.
    • setErrorMessage

      void setErrorMessage(ValueConversionException exception)
      Transposes an exception from conversion to the component as an error message.

    • getUIRef

      default @UIRef String getUIRef()
      Gets the @UIRef path to this component. This path is relative the panel or context menu that is located in the Panel Module directory.
