As an aid to understanding the EIPManagerClass, it is useful to organize its 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 EIPManagerClass 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:

Run run this procedure
InitD initialize the EditClass object
InitControls initialize edit-in-place controls
KillD shut down the EditClass object

Mainstream Use:

TakeEvent (d) handle events for the edit control
TakeNewSelection (d) handle Event:NewSelection

Occasional Use:

AddControl register edit-in-place controls
ClearColumn (v) reset column property values
CreateContol (v) a virtual to create the edit control
GetEdit (v) identify edit-in-place field
Next get the next edit-in-place field
ResetColumn (v) reset edit-in-place object to selected field
SetAlerts (v) alert appropriate keystrokes for the edit control
TakeAction (v) process end user actions
TakeCompleted (v) process completion of edit
TakeFocusLoss (v) process loss of focus
TakeFieldEvent (d) handle field specific events

(d) These methods are also derived.

(v) These methods are also virtual.

Virtual and Derived Methods

Typically you will not call these methods directly–the Non-Virtual Methods call them. However, we anticipate you will often want to override these methods, and because they are either derived or virtual, they are very easy to override. These methods do provide reasonable default behavior in case you do not want to override them.

InitD initialize the EditClass object
Kill (d) shut down the EditClass object
TakeEvent (d) handle events for the edit control
TakeNewSelection (d) handle Event:NewSelection
ClearColumn (v) reset column property values
CreateContol (v) a virtual to create the edit control
GetEdit (v) identify edit-in-place field
ResetColumn (v) reset edit-in-place object to selected field
SetAlerts (v) alert appropriate keystrokes for the edit control
TakeAction (v) process end user actions
TakeCompleted (v) process completion of edit
TakeFocusLoss (v) process loss of focus
TakeFieldEvent (d) handle field specific events
