Removes a bitmap from the list.
#include "ltwrappr.h"
virtual L_INT LBitmapList::RemoveItem(uIndex, pRemovedBitmap)
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. When you remove a bitmap from a list, the indexes of other bitmaps change to accommodate the removal.
Pointer to the bitmap object that references the removed bitmap. You can use this object afterward to work with the individual bitmap.
Value | Meaning |
---|---|
SUCCESS | The function was successful. |
< 1 | An error occurred. Refer to Return Codes. |
This function does not free the bitmap. If you want to remove a bitmap from a bitmap list and free the bitmap, you should use LBitmapList::DeleteItems.
You cannot use this function to update a bitmap list while it is being used in an animation playback.
Win32, x64.
