LAnimationWindow::SetAt

#include "ltwrappr.h"

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

L_UINT nIndex;	/* index of the bitmap to overwrite */
LBitmapBase * pBitmap;	/* pointer to the source bitmap handle */
L_BOOL bReflectIndex;	/* flag that indicates whether to set the class object's current index to the passed index */

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

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

Returns

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

Comments

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.
