Form
A form object of the type Form is used to organize a main form in one or more subforms. To embed a subform, you create a link to it by selecting the form you would like to link to from the Form reference of the Settings window for the subform. The figure below shows an example where one of the cells of a form emailServer has a link to the subform serverSettings. The Form object has the name emailSettingsForm. This example is taken from the application Tubular Reactor. For more information, see Tubular Reactor:
The figure below shows the referenced form serverSettings, which is a local form to the form emailServer.
If you are using grid layout mode, then you can quickly create subforms using the Extract Subform button in the ribbon. See Extracting Subforms.
