L_AnnSetTextOptions

#include "l_bitmap.h"

EXT_FUNCTION L_AnnSetTextOptions (hObject, pTextOptions, uFlags);

HANNOBJECT hObject;

/* handle to the annotation object */

pANNTEXTOPTIONS pTextOptions;

/* pointer to a structure that specifies the text options */

L_UINT uFlags;

/* flags that determine which objects to process */

Sets the text options for the annotation object. This function is available in the Document/Medical Toolkits.

Parameter

Description

hObject

Handle to the annotation object.

pTextOptions

Pointer to an ANNTEXTOPTIONS structure that specifies the text options to set.

uFlags

Flags that determine which objects 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

Use this function to set the text options of any annotation object that uses text. To use this function, declare a variable of type ANNTEXTOPTIONS, and pass the address of this variable for pTextOptions. For more information, refer to the documentation for the structure ANNTEXTOPTIONS.

The hObject parameter must be one of the following types:

image\sqrblit.gif ANNOBJECT_AUTOMATION

image\sqrblit.gif ANNOBJECT_TEXT

image\sqrblit.gif ANNOBJECT_TEXTPOINTER

image\sqrblit.gif ANNOBJECT_STAMP

image\sqrblit.gif ANNOBJECT_NOTE

image\sqrblit.gif ANNOBJECT_PUSHPIN

image\sqrblit.gif ANNOBJECT_BUTTON

Otherwise ERROR_FEATURE_NOT_SUPPORTED is returned.

Note: In Version 14.5, you need first to enable this function by calling L_AnnSetOptions with the OPTIONS_NEW_TEXT_OPTIONS flag.
