Create Company Form
On the client node, go to 'Forms'. Right click on the node to create the Company The Scout documentation has been moved to https://eclipsescout.github.io/. [1]. As name of the form, enter Company
and choose to create the Form ID which is the primary key of the company [2]. Click next to choose from the artefacts which also should be created [3]. Uncheck all permissions as The Scout documentation has been moved to https://eclipsescout.github.io/. is not part of this tutorial. Also, we uncheck the NewHandler
to only access existing companies.
As page layout, chooseAbstractPageWithTable
[4] to create a page representing tabular data. On the next step, enterCompany
as name for that page and choose to add this page to theMainOutline
[5]. By clicking Finish, the page is created and attached to the MainOutline.
Create columns
On the CompanyTablePage
node, go to 'Table' | 'Columns'. Right click on the node to create a new The Scout documentation has been moved to https://eclipsescout.github.io/. [6]. Please add the following three columns to that table:
CompanyNrColumn Type: Long Column [7] Name: Do not fill because column represents primary key and therefore is hidden Class name: CompanyNrColumn [8]
NameColumn Type: String Column Name: Name Class name: NameColumn
SymbolColumn Type: String Column Name: Symbol Class name: SymbolColumn
To not display the CompanyNr
column because of holding the primary key, go to that column in Scout SDK and uncheck Displayable
in Scout Property View [9].
To have the columns equally distributed over the available space of the table page, go to the The Scout documentation has been moved to https://eclipsescout.github.io/. node and check Auto Resize Columns
in Scout Property View [10].
Create service to load company data from database
Finally, we have to populate the table with company data. For that purpose, we create an Outline Service. An Outline Service is just like all other services in Scout. Basically, they are plain OSGi services which are registered in plugin.xml
and are accessible by SERVICES#get(<service name>)
. Depending on the service factory chosen in their service registration, they act as proxy for client-server communication, meaning that all service requests are tunneled to the backend. For more details, please refer to The Scout documentation has been moved to https://eclipsescout.github.io/..
To create the Outline Service, go to the server node. Right click on the node 'Outline Services' to create the new outline service [11]. Please create the service as follows:
Service definition [12] Class name: MainOutlineService Super Type: AbstractService
Service registration [13]
On the second wizard page you choose where to create and to register the service.
Because the MainOutlineService
is used for client-server communication, we are required to have a service interface in the Shared Plug-In with a proxy registration on client-side.
Double click on the MainOutlineService
created to open the corresponding Java class. In there, create the operation getCompanyTableData
to load company data from database. Also add the operation signature to the service interface IMainOutlineService
to be accessible from client side.
public class MainOutlineService extends AbstractService implements IMainOutlineService { @Override public Object[][] getCompanyTableData() throws ProcessingException { return SQL.select("" + "SELECT COMPANY_NR, " + " NAME, " + " SYMBOL " + "FROM COMPANY "); } }
Load company data into CompanyTablePage
Once the MainOutlineService
is created to load company data from database, go to CompanyTablePage
to consume the service's data.
On the Scout Property View, click on the operation Exec Load Table Data
to populate the company table [14]. Implement the method as follows:
public class MainOutlineService extends AbstractService implements IMainOutlineService { @Override protected Object[][] execLoadTableData(SearchFilter filter) throws ProcessingException { return SERVICES.getService(IMainOutlineService.class).getCompanyTableData(); } }
Finally, if you launch the application, you should see something like this:
