LBitmapList::InsertItem

#include "ltwrappr.h"

virtual L_INT LBitmapList::InsertItem(pLBitmap, uIndex=(L_UINT)-1)

Inserts the specified LBitmapBase object's associated bitmap into the class object's bitmap list, or appends the bitmap to the end of the bitmap list.

Parameters

LBitmapBase * pLBitmap

Pointer to the bitmap object to insert.

L_UINT uIndex

Position of the bitmap in the list. Use (L_UINT)-1 to append the bitmap to the end of the list.

Use zero-based indexing. For example, if there are 10 bitmaps in a list, the index of the last one is 9. If you insert a bitmap within a list, the indexes of other bitmaps change to accommodate the insertion.

Returns

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

Comments

After calling this function, the bitmap handle in the list references the original image data, it is not a copy. Therefore, you should not free the bitmap that you pass in, but should instead manage the memory using the related bitmap list functions (LBitmapList::DeleteItems and LBitmapList::Destroy). This function will invalidate the passed LBitmapBase object before it returns. In order to reuse the LBitmapBase object, you must reinitialize it.

You cannot use this function to update a bitmap list while it is being used in an animation playback. Refer to the LPlayBack::Append function for more information.
