Class UICheckedMenuItem

    • Constructor Detail

      • UICheckedMenuItem

        public UICheckedMenuItem()
        Creates the component without a name. The name must be set in all cases using the setPropertyAtom call.

      • UICheckedMenuItem

        public UICheckedMenuItem​(Atom propertyAtom)
        Creates the component with the specified name. All system-reserved names for components begins with "$".
        Parameters:
        propertyAtom - the name of the component, unique within it's parent.

      • UICheckedMenuItem

        public UICheckedMenuItem​(Atom propertyAtom,
                         GProp<?>[] newValue)
                  throws PropException
        Creates the component with the specified name, initialized to contain the GProp items. All system-reserved names for components begins with "$".
        Parameters:
        propertyAtom - The name of the component, unique within it's parent.
        newValue - The array of all properties the component should have.
        Throws:
        PropException - when at least one of the properties to initialize the component with is invalid.

    • Method Detail

      • clone

        public UICheckedMenuItem 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 UIComp

      • getSelectionPropAtom

        public Atom getSelectionPropAtom()
        Returns the selection property atom for verification of selection changes.

        This method is used by the framework in UIComp to fire selection events when the property value changes.

        Specified by:
        getSelectionPropAtom in interface IUISelectionComp
        Returns:
        The atom of the selection property.

      • getDeviceType

        public final int getDeviceType()
        Gets the device type: -1=mobile, 0=both, 1=desktop.
        Specified by:
        getDeviceType in interface IUIComp

      • onValueChanged

        public void onValueChanged​(VSField field,
                           Value value,
                           GProp<?> trigger,
                           IPostEventProcessing postProcessing)
        Called when the field value is set.

        The check component overrides this method to set the check state in the component accordingly.

        Specified by:
        onValueChanged in interface IVSFieldListener
        Overrides:
        onValueChanged in class UIComp
        Parameters:
        field - The VS field.
        value - The value, never null, but value.isNull() could be true.
        trigger - The trigger property that may be null.
        postProcessing - Post-processing instance.

      • onSelectionChanged

        protected void onSelectionChanged​(GEvent event)
        Method called when the selection of the component changed due to a property change (value changed, property added or removed).
        Overrides:
        onSelectionChanged in class UIComp
        Parameters:
        event - The event that causes the selection change.

      • canRequestFocus

        public java.lang.String canRequestFocus()
        Returns if this component can receive focus. Focus capable components may override to return null for success, or other error message.
        Specified by:
        canRequestFocus in interface IPropCnr
        Overrides:
        canRequestFocus in class UIComp
        Returns:
        "Checked menu item not focusable" always.

      • couldRequestFocusIfVirtualized

        public java.lang.String couldRequestFocusIfVirtualized​(boolean ignoreStates)
        Returns if this component could receive focus if it would be virtualized. Focus capable components may override to return null for success, or other error message.
        Specified by:
        couldRequestFocusIfVirtualized in interface IPropCnr
        Parameters:
        ignoreStates - Flag indicating that states should be ignored, such as visible or enabled. If false, hidden or disabled components return an error message.
        Returns:
        "Checked menu item not focusable" always.

      • onPrepare

        protected void onPrepare​(ClassReference cr,
                         java.util.List<java.lang.Throwable> errors)
        Called to resolve methods for the component from main "onPrepare" once the ClassReference has been found.

        Components should override this method to load it's required methods.

        Overrides:
        onPrepare in class UIComp
        Parameters:
        cr - The class reference with a valid reference.
        errors - The list of errors that is returned to the caller in case resolving fails.

      • getOnUISelectionMethod

        public java.lang.reflect.Method getOnUISelectionMethod()
        Returns the method to use for onUISelection notifications that is attached to this selection component. The method name is not important, but must have the annotation and signature:

        @OnUISelection(name = "some/property")
        public void onUISelection(UISelectionEvent event)

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

      • getApproximateSize

        public Size getApproximateSize()
        Returns the size of the component in pixels. The size is a calculation and does not exactly reflect the real size that may be different due to additional styles not taken into account by this method. The size is calculated from the font of the component and default or defined values (such as character length or number of lines for text area).
        Specified by:
        getApproximateSize in class UIComp
        Returns:
        The size of the component: 0x0 (none).
