L_LTKRN_API L_INT L_RemoveBitmapListItem(hList, uIndex, pBitmap)
HBITMAPLIST hList; |
/* handle to the list of bitmaps */ |
L_UINT uIndex; |
/* position of the bitmap in the list */ |
pBITMAPHANDLE pBitmap; |
/* pointer to the bitmap handle */ |
Removes a bitmap from the list, and lets you treat it as an individual bitmap.
Parameter |
Description |
hList |
Handle to the list of bitmaps. |
uIndex |
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. |
pBitmap |
Pointer to the bitmap handle that you can use afterward to work with the individual bitmap. |
Returns
SUCCESS |
The function was successful. |
< 1 |
An error occurred. Refer to Return Codes. |
Comments
This function does not free the bitmap. If you want to remove a bitmap from a list and free the bitmap, you should use L_DeleteBitmapListItems.
You cannot use this function to update a bitmap list while it is being used in an animation playback.

Example
This example removes even numbered bitmaps from a list and deletes them.
L_INT RemoveBitmapListItemExample(HBITMAPLIST hList) { L_INT nRet; BITMAPHANDLE TmpBitmap; /* Temporary bitmap for manipulating the list */ L_UINT i; /* Loop counter */ L_UINT uCount; /* Number of bitmaps in the list */ /* Remove even numbered bitmaps from the list and delete them */ nRet = L_GetBitmapListCount(hList, &uCount); if(nRet != SUCCESS) return nRet; for (i = 0; i <= uCount; i += 2) { nRet = L_RemoveBitmapListItem(hList, i, &TmpBitmap); L_FreeBitmap(&TmpBitmap); } return SUCCESS; }
