Release 10.1A: OpenEdge Development:
ADM Reference

viewObject

Procedure that logically views the current object and sets its ObjectHidden property to FALSE.

Location: smart.p

Parameters: None

Notes:

The ADM supports a logical concept of viewing that you can apply to all objects regardless of whether they have a visualization.
When an object is:
Viewed, the linkState property is typically set to active which activates the links.
Hidden, the link is sometimes deactivated, depending on the link type. If an object has an actual visualization, the version of viewObject in visual.p views it.
When a SmartContainer is viewed, it is not necessary for all of the objects it contains to be individually viewed, because they are not explicitly hidden when the container is hidden (see hideObject). For this reason, viewObject, when executed for a SmartContainer, sets the property ContainerHidden to FALSE in each contained SmartObject, without actually running viewObject in each object. The setContainerHidden function then sets the ObjectHidden property to FALSE so that it can be queried successfully. Not running hideObject and viewObject in each individual SmartObject improves performance when SmartObjects are being paged (alternately hidden and viewed), and can eliminate problems with “flashing” of visual objects or problems restoring proper frame order when objects are hidden and viewed.
Examples:

/* Views an object when a button is pressed. */ ON CHOOSE OF Btn_View_Browser DO:   RUN viewObject IN hSDBrowser. END.
