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 contains only 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 (or select this action in the contextual menu) and complete the fields of the Category definition section that opens up.
  3. Place your cursor in the adequate category in the tree, on the line you want to insert a new element.
  4. You can then add one of the following elements:
    1. A Data Element. To do so, click Add Data Element , select a Data Element in the dialog box that opens up and complete the fields of the Field definition section. After a field has been inserted, you can specify additional controls on this field (such as 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 that opens up.
    2. A label. To do so, click Add Label and complete the fields of the Label definition section that opens up.
    3. A Screen call. To do so, click Add Screen element, select a Screen in the dialog box that opens up and complete the fields of the Screen call definition section.
    Note: The possible actions with the buttons are also available in the contextual menu of the table.
