The Scout documentation has been moved to https://eclipsescout.github.io/.

A template is some portion of code (a class) that is defined to be used many times in the The Scout documentation has been moved to https://eclipsescout.github.io/..

Overview

The templates are visible in the The Scout documentation has been moved to https://eclipsescout.github.io/. under your scout project > Client > Templates

Form Field template

An easy way to reuse form field code is to use templates.

Consider the following example: A group box for the billing address containing some fields.

   @Order(10.0)
   public class BillingAddressBox extends AbstractGroupBox {
     @Override
     protected String getConfiguredLabel() {
       return TEXTS.get("BillingAddress");
     }
     @Order(10.0)
     public class StreetField extends AbstractStringField {
       @Override
       protected String getConfiguredLabel() {
         return TEXTS.get("Street");
       }
     }
     @Order(20.0)
     public class CityField extends AbstractSmartField<Long> {
       @Override
       protected Class<? extends ICodeType<?>> getConfiguredCodeType() {
         return CityCodeType.class;
       }
       @Override
       protected String getConfiguredLabel() {
         return TEXTS.get("City");
       }
     }
   }

Now let's assume you would like to create a similar box for the correspondence address without copying the code. This is possible by selecting "Create template..." on the group box.

A new abstract class is created containing the code of BillingAddressBox. To make the AddressBox template more useful, we move the configured label code to the BillingAddressBox.

...
@FormData(value = AbstractAddressBoxData.class, sdkCommand = SdkCommand.CREATE, defaultSubtypeSdkCommand = DefaultSubtypeSdkCommand.CREATE)
public abstract class AbstractAddressBox extends AbstractGroupBox {
/*  @Override
 protected String getConfiguredLabel() {
   return TEXTS.get("BillingAddress");
 } */
 public CityField getCityField() {
   return getFieldByClass(CityField.class);
 }
...

...
   @Order(10.0)
   public class BillingAddressBox extends AbstractAddressBox {
     @Override
     protected String getConfiguredLabel() {
       return TEXTS.get("BillingAddress");
     }
   }
...

Now the correspondance address field can be created by choosing the template as type for the new field.

   @Order(20.0)
   public class CorrespondanceAddressBox extends AbstractAddressBox {
     @Override
     protected String getConfiguredLabel() {
       return TEXTS.get("Correspondance");
     }
   }
