Class DefaultWidgetFactory

java.lang.Object
  org.kuali.student.common.ui.client.configurable.mvc.DefaultWidgetFactory

Direct Known Subclasses:

DefaultWidgetFactoryImpl

public abstract class DefaultWidgetFactory
extends Object

Returns a corresponding auto generated widget based on metadata. Not all fields can have their widgets reliably generated (or it may be better to not use the default), in these cases pass the custom widget into FieldDescriptor directly.
Things within the metadata taken into account: access = meta.getWriteAccess();
isMultiLine - uses text area for multiline
isRepeating - if this is true and the metadata has lookupdata generates a picker that can be used to produce a list
isRichText = MetadataInterrogator.hasConstraint(meta, ConstraintIds.RICH_TEXT);
maxLength - affects how long a text field will be
type - affects why kind of widget is generated
lookupMeta - generates a widget that is backed by a search and based on attributes in its lookupMeta
additionalLookups - additional lookups for the generated widget
canEdit
canUnmask
canView
Note that this class can use gwt deferred binding to have its DefaultWidgetFactory implementation overridden with a custom one, though the result is high impact for as most fields rely on this class. Default widget abstract class - see DefaultWidgetFactoryImpl for implementation.
