Displaying Detail Items
Functions Introduced:
Each of the displayable item types has four display functions.
The Show function displays the detail item, such that it is repainted on the next draft regeneration.
The Remove function undraws the detail item permanently, so that it is not redrawn on the next draft regeneration.
The Draw function draws the detail item temporarily, so that it is removed on the next draft regeneration.
The Erase function undraws the detail item temporarily, so that it is redrawn on the next draft regeneration, if it was previously “shown”.
Use the Show function after creating an item, and the Remove function before deleting it. Use the Erase function before modifying an item, and the Draw function afterwards.
 These functions require that the drawing must be the currently displayed model. To create or modify detail items in a model that is not currently displayed, use the attributes in the data structures related to Display. For example use ProDtlnotedataDisplayedSet() to set the item to be saved with the displayed status turned on, so that the next retrieval of the model will display the item. |
