L_LTANN_API L_INT L_AnnSetAutoDefaults(hAutomation, hObject, uFlags)

HANNOBJECT hAutomation;

/* handle to the automation object.*/

HANNOBJECT hObject;

/* handle to the annotation object.*/

L_UINT uFlags;

/* flags that determine which objects to process */

Assigns the default properties of the specified automation object to the specified annotation object.

Parameter

Description

hAutomation

Handle to the automation object.

hObject

Handle to the annotation object.

uFlags

Flags that determine which objects, referenced by hObject, to process. Most of the flags apply only to container objects. You can combine values when appropriate by using a bitwise OR ( | ). The following are valid values:

 

Value

Meaning

 

0

Process only the specified object.

 

ANNFLAG_SELECTED

[0x0001] Process only objects that have the selected property set to TRUE. For getting and setting the selected property, use the L_AnnGetSelected and L_AnnSetSelected functions.

 

ANNFLAG_NOTTHIS

[0x0004] Process only one level of objects within the specified container, not the container itself. If there are containers within the container, they are modified, but the objects within them are not.

 

ANNFLAG_RECURSE

[0x0008] Process objects within a container, and within any subcontainers, down to any level.

 

ANNFLAG_NOTCONTAINER

[0x0002] (Used with ANNFLAG_RECURSE) Process objects within containers, not the containers themselves.

 

ANNFLAG_NOINVALIDATE

[0x0010] Do not invalidate the affected rectangle in the window. Use this to avoid generating unwanted paint messages.

Returns

SUCCESS

The function was successful.

< 1

An error occurred. Refer to Return Codes.

Comments

This function simulates the action that takes place when an annotation object is created using the automated mode. An annotation object created in automated mode receives the same default properties as the automation object, such as foreground color, line width, etc. This lets you assign the same default properties in an automation object to the specified annotation object.
