Class: Entry_View_Client_mixin

When activate is performed (as opposed to set current_scope) the first focusable object is activated. Should the first item of the first object become the current_item? If Top_View is true and Top_Item is false you get the old dac behaviors.

**JJT**(2) New properties when false activate will attempt to activate the scope_focus when true, activate activates first object.

**JJT**(2) New properties

keeps track of main-file record when new view is entered! this was public but is no longer user. RowId replaces it. Property Integer Initial_Main_record 0 // obsolete...should it be maintained?

**JJT**(2) When changing views this will keep track of the object that had the focus when this view (scope) was exited. This manages nested scopes within a view.

**JJT**(2) New properties If Main_DD is defined View_latch_state = T : Latch if main-file exists View_latch_state = F : Clear the buffer Default_View_Latch_State

default name...could be useful

internal use

Augmented to allow views to take the focus without changing the focus within the object. The property Auto_top_View_State controls this. If true, always return to first object, first item. If false return to current-item of scope focus (when possible).

**JJT**(2) --- Start of changes Augmented to send Opening_view. If add_focus fails it sends closing_view to reverse effects of Opening_view

Disconnect servers from deos according to rules.

Augmented to Send Closing view as of 15.1 we changed all deactivating/activating signatures to not return values (see windows.pkg / ComboForm / Activating for more) Returns Integer

Views don't delegate to get this property. It uses system default

augment for dependent_item view support v.1.1

added to make the file buffers more reliable

Augment exit_application_check. If a change is detected activate the changed view. This way the user sees what has been changed.

Augment to keep track of the scope that had the focus when this view was exited. Exiting_Scope seems to get called at the right times - only when focus is moved to an object outside of view's focus.

Needed by view. Find the record number of the requested file. If file = 0 use the main_file of Main_DD (if it exists).

Returns The last scope in the view to have the focus. Before returning the value make sure that the scope object is active, else return 0

1) Take care of any buffer initialization

only called if Main_DD exists and it is not yet in-use

use to preload anything into DSOs. By default, if a Main_DD is defined, we will attempt to latch on the record that was in the buffer when the view was entered!

A normal will have its scope_state true and no scoped children. However, a zoom might be scoped. We control this by keeping track of the scope when a scope is exited.
