L_LTANN_API L_INT L_AnnGetTextExpandTokens(hObject, pbTextExpandTokens)

HANNOBJECT hObject;	/* handle to the annotation object */
L_BOOL *pbTextExpandTokens;	/* address of variable to be updated */

Gets a value that indicates whether the annotation object's text tokens will expand.

This function is available in the Document and Medical Imaging toolkits.

Parameter	Description
hObject	Handle to the annotation object
pbTextExpandTokens	Address of the variable to be updated with the object's text expand token property. Possible values are:
	Value	Meaning
	TRUE	Text tokens will be expanded for this object.
	FALSE	Text tokens will not be expanded for this object.

Returns

SUCCESS	The function was successful.
< 1	An error occurred. Refer to Return Codes.

Comments

This function gets a value that indicates whether the text tokens will be expanded for certain annotation objects that display text. The function is valid only for the following annotation objects:

ANNOBJECT_AUTOMATION
ANNOBJECT_BUTTON
ANNOBJECT_NOTE
ANNOBJECT_PUSHPIN
ANNOBJECT_STAMP
ANNOBJECT_TEXT
ANNOBJECT_TEXTPOINTER

Calling this function on an object other than one listed above will return ERROR_FEATURE_NOT_SUPPORTED.

If pbTextExpandTokens is updated with TRUE, then all tokens will be expanded.

For example, if you have an ANNOBJECT_BUTTON object that will expand text tokens, and #D is defined to be the current day of the week (ANNTOKEN_DATE_DAY_OF_WEEK), then entering #D for the text of this button will cause it to display the current day of the week when in design or run mode.
