#include "ltwrappr.h"
virtual L_INT LAnnAutomation::GetText(pText, puLen)
L_TCHAR * pText; |
/* character string to be updated */ |
L_SIZE_T *puLen; |
/* address of an integer variable to be updated with text length*/ |
Gets the text (character string) of the annotation object. This function is available in the Document/Medical Toolkits.
Parameter |
Description |
pText |
Character string to be updated with the annotation object's character string. |
puLen |
Pointer to a variable to updated with the text length. |
Returns
SUCCESS |
The function was successful. |
< 1 |
An error occurred. Refer to Return Codes. |
Comments
Before calling this function, you must declare a variable as a pointer to a character string. Then, pass the variable in the pText parameter. This function will update the variable with the annotation object's character string.
GetText can be used to retrieve text that was set using LAnnAutomation::SetTextRTF, but no formatting information will be preserved. To retrieve the text with formatting, use LAnnAutomation::GetTextRTF.
Note: |
The text of the ruler object, which can be retrieved through LAnnRuler::GetText and LAnnRuler::GetTextLen, is the length + unit abbrev. The distance is reset every time the object is changed. |
