Overwrites the internal bitmap handle of a bitmap in a list. Use this function with LAnimationWindow::GetAt to manipulate a bitmap in a list.


#include "ltwrappr.h"

L_INT LAnimationWindow::SetAt(nIndex, pBitmap, bReflectIndex = FALSE)


L_UINT nIndex

Position of the bitmap in the list. Use zero-based indexing. For example, if there are 10 bitmaps in a list, the index of the last one is 9.

LBitmapBase * pBitmap

Pointer to the bitmap handle that will overwrite the internal bitmap handle in the list.

L_BOOL bReflectIndex

Flag that indicates whether to set the class object's current index to the passed index. Possible values are:

Value Meaning
TRUE Set the class object's current index to the passed index.
FALSE Do not set the class object's current index to the passed index.


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


When a bitmap is in a list, you do not have direct access to the bitmap handle. Therefore, to do any image processing, you must first use LAnimationWindow::GetAt to get a copy of the internal handle, then do the image processing, then update the internal handle using LAnimationWindow::SetAt.

You cannot use this method to update a bitmap list while it is being used in an animation playback.
