Defining the Screen elements and layout

The elements which make up a Screen are: Data Elements, labels or Screen calls. To insert any of these, and to specific their display characteristics in the Screen layout, you must open the -CE Lines tab of a Screen.

To define the Screen elements, you must then:
  1. Open the-CE Lines tab of a Screen. To do so, select a Screen in the Design explorer view of the Design perspective and double-click on it or select Open in the popup menu. Then access its -CE Lines tab from the Overview tab or directly by clicking the -CE Lines tab.
  2. In the tree, located on the left-hand side of the tab, add a category if necessary. When it is created, a Screen only contains the top category. The top category is not displayed in the tree but by default, if you do not specify any other category, all the Screen elements you will specify will be inserted in the top category. So if you need to add a repetitive or a bottom category, click the Add a category button and fill in all the fields of the Category definition section which opens up on the right-hand side of the tab.
  3. Place your cursor in the adequate category in the tree, on the line after which you want to insert a new element.
  4. You can then add a:
    1. Data Element. To do so, click the Add Data Element button and fill in the fields of the Field definition section which opens up. Once a field has been inserted, you can specify additional controls on this field (presence check, validation conditions, update option...). To do so, select a field (a Data Element) already inserted in the tree and click the Add additional controls for the field. Then you must fill in the fields of the Additional controls for the field section which opens up.
    2. Label. To do so, click the Add Label button and fill in the fields of the Label definition section which opens up.
    3. Screen call. To do so, click the Add Screen element button and fill in the fields of the Screen call definition section which opens up.
