L_AnnSetTextRTF

Summary

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.

Syntax

#include "l_bitmap.h"

L_LTANN_API L_INT L_AnnSetTextRTF(hObject, uFormat, pText, uFlags)

Parameters

L_UINT 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.

L_TCHAR *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.

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

Returns

Value	Meaning
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. Only ANNOBJECT_RTF and ANNOBJECT_AUTOMATION objects are affected.

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 L_AnnGetTextLen, L_AnnGetText, and L_AnnSetText.
