|
|
* TODO:
|
|
* - Fix ImageList_DrawIndirect (xBitmap, yBitmap, rgbFg, rgbBk, dwRop).
|
|
* - Fix ImageList_GetIcon.
|
|
* - Fix ImageList_SetFilter (undocumented).
|
|
* BTW does anybody know anything about this function???
|
|
* - It removes 12 Bytes from the stack (3 Parameters).
|
|
* - First parameter SHOULD be a HIMAGELIST.
|
|
* - Second parameter COULD be an index?????
|
|
* - Third parameter.... ?????????????????????
|
|
*
|
|
* Comments:
|
|
* - ImageList_Draw, ImageList_DrawEx and ImageList_GetIcon use
|
|
* ImageList_DrawIndirect. Since ImageList_DrawIndirect is still
|
|
* partially implemented, the functions mentioned above will be
|
|
* limited in functionality too.
|
|
*
|
|
* - Hotspot handling still not correct. The Hotspot passed to BeginDrag
|
|
* is the offset of the image position relative to the actual mouse pointer
|
|
* position. However the Hotspot passed to SetDragCursorImage is the
|
|
* offset of the mouse messages sent to the application...
