Defining the Screen elements and layout

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

About this task

To define the Screen elements, you must perform the following steps:

Procedure

  1. Open the-CE Lines tab of a Screen. To do so, select a Screen in the Design Explorer view and double-click or right-click and select Open. Then access its -CE Lines tab from the Overview tab or directly by clicking the -CE Lines tab.
  2. Add a category if necessary, in the table. When it is created, a Screen only contains the top category. This top category line is not displayed in the tree by default but if you do not specify any other category, all the Screen elements are inserted in this category. So to add a repetitive or a bottom category, click Add a category and complete the fields of the Category definition section which opens up.
  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 Add Data Element and complete 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 complete the fields of the Additional controls for the field section which opens up.
    2. Label. To do so, click Add Label and complete the fields of the Label definition section which opens up.
    3. Screen call. To do so, click Add Screen element and complete the fields of the Screen call definition section which opens up.
