public class SimpleType extends BaseClass
SimpleTypes can be created at any time, and subsequently referred to as a
field type
in DataSources
and
DataBoundComponents
. This allows you to define
validation
, formatting
and editing
behaviors for a type to be reused across all
DataBoundComponents
.
The SimpleType class also allows data to be stored in some opaque format but treated as
simple atomic values as far as Smart GWT components are concerned by implementing
getAtomicValue()
and updateAtomicValue()
methods.
For example, if some record has a field value set to a javascript object with the
following properties:
{ stringValue:"A String", length: 9 }this value could be treated as a simple string by defining a SimpleType with
inheritsFrom
set to "text"
and a custom
getAtomicValue()
method that simply extracted the "stringValue"
attribute from the data object. DataBoundComponents would then display
the string value, and use it for sorting and other standard databinding features.
Note that the term "simpleType" is used in the same sense as in
http://www.w3.org/TR/xmlschema-0/, and
XMLTools.loadXMLSchema()
will create new SimpleType definitions.
When using the Smart GWT Server, SimpleTypes can be defined server-side, and should be defined server-side if validators are going to be declared so that the server will enforce validation. To define server-side SimpleTypes using Component XML you should create file {typeName}.type.xml in the following format:
<SimpleType name="{typeName}" inheritsFrom="{otherSimpleType}" editorType="{FormItemClassName}"> <validators> <!-- validator definition just like DataSourceField --> </validators> </SimpleType>.. and place this file alongside your DataSource files (.ds.xml) files - in any of folders listed in
project.datasources
property in server.properties
.
SimpleTypes can be loaded via DataSourceLoader or loadDS JSP tags
and
should be loaded before the definitions of any DataSources that use them (so
generally put all SimpleType definitions first).
Define validators in the server-side type definition, for example:
<SimpleType name="countryCodeType" inheritsFrom="text"> <validators> <validator type="lengthRange" min="2" max="2" errorMessage="Length of country code should be equal to 2." /> <validator type="regexp" expression="[A-Z][A-Z]" errorMessage="CountryCode should have only uppercase letters." /> </validators> </SimpleType>
For client-side formatters, add these to the type definition after loading it from the server, for example:
SimpleType.getType("independenceDateType").setShortDisplayFormatter(new SimpleTypeFormatter() { public String format(Object value, DataClass field, DataBoundComponent component, Record record) { if (value == null) return null; return "<i>" + (((java.util.Date) value).getYear() + 1900) + "</i>"; } });Note that formatters must be added to the SimpleType definition before any DataBoundComponent binds to a DataSource that uses the SimpleType.
An example is here.

FormItem
configuration for editing values of this type.
You can create a simple custom FormItem by adding default
icons
that launch custom value picking dialogs (an example is in the QuickStart Guide, Chapter 9,
Extending Smart GWT).
By setting simpleType.editorProperties to an instance of your custom FormItem, forms will
automatically use the custom FormItem, as will grids performing
grid editing
.
Note: When you supply a custom FormItem via setEditorProperties(), you're really providing properties which are then used to create
multiple FormItems (e.g., in grids, forms and trees) and there's an underlying limitation here where event handlers have to be written to
dynamically receive the actual FormItem rather than relying on "this" (because there's more than one "this").
This means you need to follow the special rules indicated for
DataSourceField.setEditorProperties(FormItem)
.
As an alternative, you can use setEditorType(String)
or
setEditorType(Class)
to avoid these limitations, if you register
the FormItem subclass with the reflection mechanism
