This is a Web App wrapper component, that ensures that the application component runs authenticated. If upon app initialization, it is not yet authenticated to a 4D backend, this component will display a Login dialog to get user credentials and authenticate the user.

This Component should be used in cases where your Application acts as a workspace area for other sub-applications, usually lazy loaded, that run under it. But those sub-applications may also run standalone. Thus the Web App wrapper will ensure those sub-apps run authenticated to the 4D Backend database, if running in standalone mode.

The component's selector is <web-application>, and here is an example usage:

    <web-application>
        <record-list [editWindow]="editWindow" [dialogInstance]="dialog">
            <query-band [enableSort]="true" [enableQBE]="true" [enableButtonBar]="true" [enableAddRecord]="true" [enableDeleteRecord]="true">
                <queryband class="form-group">
                    <features-queryband #customQueryBand class="form-group"></features-queryband>
                </queryband>
                <custombuttonbar>
                    <button class="regularButton" style="width:120px;" (click)="checkFeature()">Analyze</button>
                </custombuttonbar>
            </query-band>
           <datagrid
                [model]="model"
                [columns]="columnDefs"
                [useLazyLoading]="true"
                [optimizeGridLoading]="true"
                [pageSize]="50"
                [excelFilename]="'FeatureList.xlsx'"
                >
            </datagrid>
        </record-list>
    </web-application>

The Component takes no input and has no API, as it is simply a wrapper to other sub-applications.
