LAnnAutomation::SetTextRTF

Show in webframe

#include "ltwrappr.h"

virtual L_INT LAnnAutomation::SetTextRTF(uFormat, pText, uFlags)

L_UINT uFormat;

/* text format type */

L_TCHAR * pText;

/* pointer to the text

L_UINT uFlags;

/* flags that determine which objects to process */

Sets the text (unformatted text or rich text) of one or more ANNOBJECT_RTF annotation objects. It can also set the rich text of an ANNOBJECT_AUTOMATION object.

Parameter

Description

uFormat

Value that specifies the text format type. Possible values are:

 

Value

Meaning

 

RTFFORMAT_TEXT

[0x0001] Interpret the text as unformatted text.

 

RTFFORMAT_RTF

[0x0002] Interpret the text as rich text.

pText

Character string that contains the text to assign to the annotation object. This can be unformatted text, or rich text. This is a NULL terminated string.

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 LAnnotation::IsSelected and LAnnotation::SetSelected 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.

 

ANNFLAG_CHECKMENU

[0x0020] Process objects only if the ANNAUTOTEXT_MENU_TEXT menu item has been selected.

Returns

SUCCESS

The function was successful.

< 1

An error occurred. Refer to Return Codes.

Comments

This function applies to multiple and selected objects based on values of the uFlags parameter.

This function does not affect objects that do not have this property or that do not let you change the property. For descriptions of the various types of objects and their properties, refer to Types of Annotations.

To get or set the text of other text objects, see the documentation for LAnnAutomation::GetTextLen, LAnnAutomation::GetText, and LAnnAutomation::SetText.
