Method Detail

• onStartBuild

  public void onStartBuild(SwtMetawidget metawidget)

  Description copied from interface: AdvancedLayout
  Event called at the start of the widget building process, before the WidgetBuilder is called. Layouts may wish to act on this event to initialize themselves ready for processing, or to perform 'outermost-container-only' processing, such as adding facets. This event is only called once per inspection, not once per widget built.

  Specified by:

  onStartBuild in interface AdvancedLayout<org.eclipse.swt.widgets.Control,org.eclipse.swt.widgets.Composite,SwtMetawidget>

  Parameters:

  metawidget - the parent Metawidget. Never null

• startContainerLayout

  public void startContainerLayout(org.eclipse.swt.widgets.Composite composite,
                          SwtMetawidget metawidget)

  Description copied from interface: AdvancedLayout
  Initialise the given container, using the given Metawidget to access additional services if needed (such as state saving).

  Specified by:

  startContainerLayout in interface AdvancedLayout<org.eclipse.swt.widgets.Control,org.eclipse.swt.widgets.Composite,SwtMetawidget>

  Parameters:

  composite - the container to layout. This is often the same as the given Metawidget

  metawidget - the parent Metawidget. Never null

• layoutWidget

  public void layoutWidget(org.eclipse.swt.widgets.Control control,
                  String elementName,
                  Map<String,String> attributes,
                  org.eclipse.swt.widgets.Composite composite,
                  SwtMetawidget metawidget)

  Description copied from interface: Layout
  Layout the given widget within the given container, using the given elementName and attributes as a guide and the given Metawidget to access additional services if needed (such as state saving)

  layoutWidget is called immediately after WidgetBuilder.buildWidget and WidgetProcessor.processWidget, and before the next widget is generated. An alternate design would be to 'collect' all widgets generated by buildWidget and processWidget, then iterate over them separately for the layout. If you prefer this approach, you can simulate it by having layoutWidget do nothing but 'remember' each widget, then iterate over them in endContainerLayout (see the AdvancedLayout interface). However not all UI frameworks allow this approach, because they do not suport widgets being instantiated independent of a layout, nor moved between layouts (e.g. SWT)

  Specified by:

  layoutWidget in interface Layout<org.eclipse.swt.widgets.Control,org.eclipse.swt.widgets.Composite,SwtMetawidget>

  Parameters:

  control - the widget to layout. Never null

  elementName - XML node name of the business field. Typically 'entity', 'property' or 'action'. Never null

  attributes - attributes of the widget to layout. Never null. This Map is modifiable - changes will be passed to subsequent WidgetProcessors and Layouts

  composite - the container to add to. This is often the same as the given Metawidget

  metawidget - the Metawidget to use to access additional services. Never null

• endContainerLayout

  public void endContainerLayout(org.eclipse.swt.widgets.Composite composite,
                        SwtMetawidget metawidget)

  Description copied from interface: AdvancedLayout
  Finish the given container, using the given Metawidget to access additional services if needed (such as state saving).

  Specified by:

  endContainerLayout in interface AdvancedLayout<org.eclipse.swt.widgets.Control,org.eclipse.swt.widgets.Composite,SwtMetawidget>

  Parameters:

  composite - the container to layout. This is often the same as the given Metawidget

  metawidget - the Metawidget to use to access additional services. Never null

• onEndBuild

  public void onEndBuild(SwtMetawidget metawidget)

  Description copied from interface: AdvancedLayout
  Event called at the end of widget building, after all widgets have been built and added to the Layout. Layouts may wish to act on this event to clean themselves up after processing, or to perform 'outermost-container-only' processing, such as adding facets. This event is only called once per inspection, not once per widget built.

  Specified by:

  onEndBuild in interface AdvancedLayout<org.eclipse.swt.widgets.Control,org.eclipse.swt.widgets.Composite,SwtMetawidget>

  Parameters:

  metawidget - the parent Metawidget. Never null

• layoutBeforeChild

  protected String layoutBeforeChild(org.eclipse.swt.widgets.Control control,
                         String labelText,
                         String elementName,
                         Map<String,String> attributes,
                         org.eclipse.swt.widgets.Composite composite,
                         SwtMetawidget metawidget)

• willFillHorizontally

  protected boolean willFillHorizontally(org.eclipse.swt.widgets.Control control,
                             Map<String,String> attributes)

• willFillVertically

  protected boolean willFillVertically(org.eclipse.swt.widgets.Control control,
                           Map<String,String> attributes)

  Parameters:

  control - control that may fill vertically
