public class RowLayout extends Object implements AdvancedLayout<org.eclipse.swt.widgets.Control,org.eclipse.swt.widgets.Composite,SwtMetawidget>
org.eclipse.swt.layout.RowLayout.
This is like FillLayout, except it does not fill width. It can be useful for button
bars.

|---|---|
void |
endContainerLayout(org.eclipse.swt.widgets.Composite container,
SwtMetawidget metawidget)
Finish the given container, using the given Metawidget to access additional services if
needed (such as state saving).
|
void |
layoutWidget(org.eclipse.swt.widgets.Control control,
String elementName,
Map<String,String> attributes,
org.eclipse.swt.widgets.Composite container,
SwtMetawidget metawidget)
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)
|
void |
onEndBuild(SwtMetawidget metawidget)
Event called at the end of widget building, after all widgets have been built and added to
the
Layout. |
void |
onStartBuild(SwtMetawidget metawidget)
Event called at the start of the widget building process, before the
WidgetBuilder is called. |
void |
startContainerLayout(org.eclipse.swt.widgets.Composite container,
SwtMetawidget metawidget)
Initialise the given container, using the given Metawidget to access additional services if
needed (such as state saving).

public void onStartBuild(SwtMetawidget metawidget)
AdvancedLayoutWidgetBuilder 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.onStartBuild in interface AdvancedLayout<org.eclipse.swt.widgets.Control,org.eclipse.swt.widgets.Composite,SwtMetawidget>metawidget - the parent Metawidget. Never nullpublic void startContainerLayout(org.eclipse.swt.widgets.Composite container,

LayoutlayoutWidget 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)
