TopForm Attribute
Data Type: FrameForm
4GL Access: R
The TopForm attribute contains the form associated with a frame (a FrameForm object). The form contains all of the non-menu fields.
Two common uses of the TopForm attribute are to check whether the user has changed any data in the form (through the CurFrame.TopForm.HasDataChanged attribute) and to reset a frame to the default settings (using the CurFrame.TopForm.SetToDefault method).
