QueryListVisual--Functional Organization--Expected Use

Top  Previous  Next

As an aid to understanding the QueryListVisual class, it is useful to organize its various methods into two large categories according to their expected use--the primary interface and the virtual methods. This organization reflects what we believe is typical use of the QueryListVisual methods.

Non-Virtual Methods

The Non-Virtual Methods, which you are likely to call fairly routinely from your program, can be further divided into three categories:

Housekeeping (one-time) Use:

 

Init (d)

program the QueryListVisual object

MainStream Use:

none

Occasional Use:

none

(d) This method is also Derived.

Derived Methods

Typically you will not call these methods directly--other ABC Library methods call them. However, we anticipate you will often want to override these methods, and because they are derived, they are very easy to override. These methods do provide reasonable default behavior in case you do not want to override them.

 

Init

program the QueryListVisual object

 

SetAlerts

prepare the query dialog for EIP

 

TakeEvent

Handle events for the query dialog

 

TakeCompleted

wrap up the query dialog

 

TakeAccepted

handle EVENT:Accepted events
